Top Penetration Testing Companies in Sweden for 2026

Swedish security and procurement teams evaluating penetration testing companies need to compare more than headquarters or brand recognition. This guide reviews providers serving Sweden by human testing depth, delivery model, local relationship, reporting and retesting evidence, and practical buyer fit. It includes Sweden-headquartered firms, providers with Swedish delivery presence, and a cross-border specialist. The method matters because a localized webpage does not prove local testers, Swedish-language reporting, on-site availability, or the same technical depth across services. Evidence was reviewed with a cut-off of August 10, 2026.

Editorial disclosure: DeepStrike publishes this article and is included in the comparison. DeepStrike is placed first as an editorial choice, not because an independent universal ranking established it as the best provider for every organization. The same evidence categories are used across the list, and buyers should independently verify scope, assigned testers, contracting entity, terms, references, data handling, and local-delivery requirements before signing.

Key takeaways

• A Swedish office and a deep penetration-testing practice are separate procurement questions.
• Human-led penetration testing should be distinguished from automated vulnerability scanning and from broader PTaaS platforms that may combine people and tooling.
• Ask who will actually perform the test, what is in scope, how exploitation is controlled, what evidence appears in the report, and whether remediation verification is included.
• Swedish and EU rules can affect security-testing expectations, but NIS2, GDPR, ISO/IEC 27001, and Sweden’s Cybersecurity Act should not be treated as universal fixed-schedule penetration-test mandates.
• Choose the provider that fits the technical and procurement constraints of the engagement rather than assuming the largest or most local company is automatically the strongest fit.

How we selected the companies

The comparison uses public, first-party evidence reviewed for the August 10, 2026 research baseline. A company entered the main list only when the research set showed a current penetration-testing or directly relevant offensive-security service, a meaningful human-led component, a defensible relationship to Swedish buyers, and enough evidence to explain a concrete buyer fit and a verification question.

We did not create numerical quality scores. The qualitative dimensions are testing scope, visible human-led depth, application/API/cloud/mobile/infrastructure or adversary-simulation fit, Swedish relationship, reporting/remediation/retesting evidence, methodology transparency, practical buyer fit, and the quality of available evidence.

The relationship labels mean different things. Sweden-headquartered provider indicates a provider rooted in Sweden; provider with a verified Swedish office, legal entity, or delivery team indicates a current Swedish presence without implying that every tester is local; and international cross-border provider explicitly able to serve Swedish buyers indicates delivery into Sweden without claiming a Swedish office. Buyers should still confirm language, on-site work, security-clearance needs, data processing, subcontractors, and the exact contracting entity.

Comparison table

1. DeepStrike

Relationship to Sweden: International cross-border provider explicitly able to serve Swedish buyers. DeepStrike is not presented here as having a Swedish office, Swedish legal entity, Swedish-language reporting team, or guaranteed on-site capability.

Evidence date: August 10, 2026.

Verified service scope: DeepStrike’s current service materials describe penetration testing across web applications, APIs, cloud environments, networks, mobile applications, and related offensive-security scenarios. The company also publishes continuous-testing and red-team service material. See DeepStrike’s penetration testing services for the current service description.

Testing depth model: Human-led penetration testing supported by tooling and a delivery workflow. This article does not repeat the older claim that testing is “almost entirely manual,” because a precise automation/manual percentage was not re-established for this update.

Why it stands out: For this editorial comparison, DeepStrike is positioned for teams that want direct security validation plus remediation and retesting workflow rather than a scanner-only result. The public and CMS-reviewed DeepStrike material supports a human-led service portfolio and remediation-oriented delivery, but the buyer should still verify the assigned team and exact statement of work.

Best fit: SaaS, cloud, product-security, and enterprise teams that need hands-on validation of application, API, cloud, or multi-layer attack paths and want remediation verification included in procurement discussions.

Limitations or tradeoffs: Cross-border delivery can be a mismatch when a buyer requires a Swedish legal entity, Swedish-language deliverables, on-site work, a specific national security clearance, or restricted evidence handling. Those requirements should be tested before commercial evaluation, not assumed from remote service availability.

What to verify before buying: named testers and experience; location and subcontracting; rules of engagement; Swedish-language/on-site needs; evidence handling; data retention; retest entitlement; timeline; and capacity for the full scope.

2. Truesec

Relationship to Sweden: Sweden-headquartered provider.

Evidence date: August 10, 2026.

Verified service scope: Truesec maintains a current first-party penetration testing service page, and its corporate contact material establishes a Swedish operating presence.

Testing depth model: Human-led penetration testing with broader offensive-security adjacency. A buyer should not assume that a penetration test and a red-team engagement are interchangeable; the objective, rules of engagement, and deliverables differ.

Why it stands out: Truesec is relevant when a Swedish buyer wants a local cyber specialist and the option to connect penetration testing with broader offensive or defensive security work. The local relationship can simplify procurement and collaboration, but it should not substitute for verifying the actual testers and test design.

Best fit: Swedish enterprises and organizations that value local commercial/delivery context and may need penetration testing as part of a broader cybersecurity relationship.

Limitations or tradeoffs: The public service category alone does not establish the exact testers, effort allocation, report format, or retesting entitlement for a particular engagement.

What to verify before buying: assigned testers; application/API/cloud depth relevant to the scope; report sample; retesting terms; on-site availability; Swedish-language deliverables; and whether adjacent red-team services are actually needed.

3. Outpost24

Relationship to Sweden: Sweden-headquartered provider.

Evidence date: August 10, 2026.

Verified service scope: Outpost24 markets Penetration Testing as a Service alongside a broader product portfolio that includes automated vulnerability and exposure-management technology.

Testing depth model: Human-led penetration testing delivered through a PTaaS-oriented workflow, with tooling/platform support. This distinction matters: Outpost24’s automated products should not be treated as proof that every product is a manual pentest, and its PTaaS service should not be reduced to scanning.

Why it stands out: The provider is a strong consideration for teams that want a platform-centric workflow around testing and vulnerability management rather than a one-off report-only engagement.

Best fit: Mid-market and enterprise security teams that want human testing integrated into a broader vulnerability-management or continuous-assurance process.

Limitations or tradeoffs: Platform breadth can make procurement less obvious if the buyer does not specify which deliverable is a human penetration test versus an automated assessment or exposure-management product.

What to verify before buying: exact human testing time; named tester model; manual exploitation expectations; supported scopes; report ownership; retest entitlement; and which platform features are included in the quote.

4. Orange Cyberdefense Sweden

Relationship to Sweden: Provider with a verified Swedish office, legal entity, or delivery team.

Evidence date: August 10, 2026.

Verified service scope: Orange Cyberdefense operates a Sweden-specific first-party presence at orangecyberdefense and offers offensive-security services within its wider cybersecurity portfolio. The exact penetration-testing scope should be tied to the current Swedish proposal.

Testing depth model: Human-led offensive-security delivery with supporting tools. The public portfolio is broader than penetration testing alone, so buyers should define the specific assessment required.

Why it stands out: Orange Cyberdefense can fit organizations that want penetration testing through a larger security-services provider with a Swedish operating presence and adjacent services.

Best fit: Larger or multi-service organizations that prefer to coordinate offensive testing with a broader security supplier.

Limitations or tradeoffs: A large portfolio does not by itself establish who performs the test, whether the team is Swedish-based, or whether a particular report/retest model is standard across engagements.

What to verify before buying: the Swedish delivery team; exact contracting entity; named testers; manual test depth; red/purple-team boundaries; report sample; retest policy; data location; and on-site options.

5. Knowit

Relationship to Sweden: Sweden-headquartered provider.

Evidence date: August 10, 2026.

Verified service scope: Knowit’s Swedish cybersecurity offering explicitly includes security reviews, including penetration tests.

Testing depth model: Human-led security review that includes penetration testing. The research baseline does not justify inventing a fixed manual-versus-tool percentage.

Why it stands out: Knowit is relevant to buyers that want a Swedish consulting relationship and may value connecting technical testing with wider cybersecurity or organizational work.

Best fit: Swedish organizations that prefer a local consulting model and want penetration testing embedded in a wider assurance or security-improvement engagement.

Limitations or tradeoffs: The broad “security review” context means buyers should ensure the statement of work is a true penetration test with exploit validation, not a lighter review or vulnerability assessment.

What to verify before buying: exact penetration-test methodology; assigned testers; in-scope exploit validation; application/API/cloud specialties; report sample; remediation guidance; and retest terms.

6. Sentor

Relationship to Sweden: Provider with a verified Swedish office, legal entity, or delivery team.

Evidence date: August 10, 2026.

Verified service scope: The current Sentor first-party site maintains a Swedish penetration-testing page. Because the production research flags current ownership and contracting identity as a point that can change, this article does not make a stronger corporate-entity claim than the public service evidence supports.

Testing depth model: Human-led penetration/security testing.

Why it stands out: Sentor remains relevant for Swedish buyers that encounter the brand through local security-testing procurement and want a Sweden-oriented delivery context.

Best fit: Buyers prioritizing Swedish-market familiarity and a security-testing practice rather than an offshore scanner-only service.

Limitations or tradeoffs: Brand ownership, contracting entity, delivery team, and service packaging can change after corporate transactions. Those are commercial facts that should be verified directly rather than inferred from a historical brand name.

What to verify before buying: current contracting entity and ownership; assigned testers; scope; Swedish-language/on-site requirements; report rights; data handling; remediation support; and retest terms.

7. CyberStrike AB

Relationship to Sweden: Sweden-headquartered provider.

Evidence date: August 10, 2026.

Verified service scope: CyberStrike AB presents current cybersecurity and offensive-security services on its first-party site. The production research set treats penetration testing as a core service candidate and specifically requires verification of legal identity, Stockholm relationship, red-team claims, and current delivery evidence.

Testing depth model: Human-led penetration testing/offensive-security positioning; a fixed tooling mix is not assumed.

Why it stands out: A focused Swedish specialist can appeal to buyers who want direct access to a smaller offensive-security practice rather than a multi-service global consultancy.

Best fit: Swedish teams that prefer a specialist commercial relationship and can validate the exact tester expertise required for their environment.

Limitations or tradeoffs: Smaller-provider positioning should not be converted into assumptions about capacity, speed, price, or tester seniority. Those elements must be confirmed in the proposal.

What to verify before buying: legal entity; named testers; current service scope; red-team versus pentest boundaries; capacity; report sample; retesting; evidence retention; and on-site requirements.

8. eBuilder Security

Relationship to Sweden: Provider with a verified Swedish office, legal entity, or delivery team.

Evidence date: August 10, 2026.

Verified service scope: eBuilder Security maintains a current first-party page for penetration testing services.

Testing depth model: Human-led penetration-testing service. Tooling can support discovery and validation, but the research baseline does not justify a numerical manual-testing claim.

Why it stands out: The service is directly presented for penetration testing and is relevant to buyers that want Swedish delivery context without defaulting to a global provider.

Best fit: Swedish organizations seeking a focused penetration-test engagement with local-market delivery evidence.

Limitations or tradeoffs: A retesting statement identified during research should be rechecked against the current service terms before the buyer treats it as included for every scope.

What to verify before buying: whether retesting is included and under what conditions; assigned testers; service scope; report format; remediation support; data handling; and language/on-site requirements.

9. Cyloq

Relationship to Sweden: Sweden-headquartered provider.

Evidence date: August 10, 2026.

Verified service scope: Cyloq maintains a dedicated Swedish penetration-testing page.

Testing depth model: Human-led penetration testing.

Why it stands out: Cyloq is relevant as a Swedish specialist for buyers that want a direct pentest-focused conversation and may prefer a smaller-provider relationship.

Best fit: Organizations that value Swedish supplier context and can scope the engagement tightly around the skills of the assigned offensive team.

Limitations or tradeoffs: The production research specifically flags a claim about multiple specialists per test for reverification. This article therefore does not repeat a fixed tester-count promise.

What to verify before buying: number and seniority of assigned testers; scope breadth; methodology; report sample; retest policy; evidence handling; on-site availability; and escalation path.

10. Basalt

Relationship to Sweden: Sweden-headquartered provider.

Evidence date: August 10, 2026.

Verified service scope: Basalt maintains a first-party Swedish page for penetration testing.

Testing depth model: Human-led penetration testing. The baseline does not justify a more specific claim about exploit chaining or tooling mix.

Why it stands out: Basalt is relevant to Swedish organizations that value a domestically oriented supplier and want penetration testing as part of a broader security relationship.

Best fit: Buyers for whom Swedish delivery context, procurement fit, or sensitive-environment requirements may matter alongside technical scope.

Limitations or tradeoffs: Sensitive-sector or public-sector suitability should never be inferred from Swedish presence alone. Contract, clearance, staffing, data handling, and technical methodology must be verified for the actual engagement.

What to verify before buying: target-sector eligibility; security-clearance requirements; named testers; exact penetration-test method; report/retest process; data retention; subcontractors; and on-site delivery.

What “serving Sweden” actually means

A provider can serve a Swedish organization in several legitimate ways, but the models are not interchangeable.

A Sweden-headquartered provider may simplify local procurement and stakeholder communication, but headquarters does not prove that the assigned pentester is in Sweden, that the report will be written in Swedish, or that on-site work is included. A provider with a Swedish office, entity, or team has a local operating relationship, yet the technical work may still be delivered by a regional or global specialist. A cross-border provider can be appropriate for remote application, API, cloud, or network scopes, but buyers need to resolve contractual jurisdiction, data processing, evidence transfer, time zones, and any on-site or clearance constraints.

For that reason, “local” should be decomposed into questions: Who signs the contract? Where are the assigned testers? Where is evidence stored? Can the team work on-site if required? Is Swedish-language reporting needed? Are there public-procurement or security-protection requirements? Does the engagement permit subcontractors? The provider’s address is only one part of the answer.

Manual pentesting, PTaaS, scanning, and red teaming are not the same

A vulnerability scanner is useful for broad, repeatable discovery, but it does not by itself reproduce the judgment of an authorized human tester. A penetration test uses human decision-making to validate whether weaknesses are exploitable, examine authorization and business logic, and understand practical attack paths. For a deeper overview, see DeepStrike’s comparison of manual versus automated penetration testing.

PTaaS (Penetration Testing as a Service) is a delivery model, not a guarantee of depth. A good PTaaS program can combine human testing with scheduling, collaboration, dashboards, remediation tracking, and retesting. Buyers should still ask how much of the assessment is performed by humans and what the platform automates.

Red teaming is usually broader and more objective-driven than a normal scoped pentest. It can combine multiple attack paths and test detection/response as well as prevention. Organizations considering that model should compare the objective with a standard penetration test before buying a red-team service.

How to choose a penetration-testing company in Sweden

Start with the objective, not the vendor list. A release-focused web application assessment, a cloud identity review, a PCI-scoped test, and a DORA TLPT exercise are fundamentally different procurement problems.

1. Define assets and trust boundaries

List applications, APIs, cloud accounts, external/internal networks, mobile apps, identities, privileged roles, integrations, and third parties that matter. Decide whether you need authenticated testing and which user roles should be exercised. A vague asset count is not a complete scope.

For application-heavy environments, ask the provider to explain how its web application penetration testing approach handles authorization, business logic, and multi-role flows not just common scanner findings.

2. Define Swedish procurement constraints

Record whether you require a Swedish contracting entity, Swedish-language reporting, on-site work, security clearance, local data handling, specific subcontractor restrictions, public-procurement eligibility, or EU-only evidence storage. These conditions can eliminate otherwise capable providers before technical comparison begins.

3. Choose the right testing model

Ask whether the engagement is a human penetration test, a scanner-led assessment, a PTaaS program, continuous testing, or a red-team exercise. If your environment changes frequently, continuous penetration testing may be operationally useful, but recurring cadence does not remove the need to inspect methodology and tester quality.

4. Verify the people, not just certifications

Request the names or profiles of the people expected to perform the work, their relevant experience, and which parts of the engagement may be subcontracted. Certifications can be supporting evidence, but they should not replace direct questions about the tester’s experience with your technology and threat model.

5. Lock the rules of engagement

The statement of work should define authorization, target boundaries, testing windows, excluded techniques, stop conditions, escalation contacts, handling of production data, credential use, denial-of-service restrictions, social-engineering boundaries, and incident procedures. NIST SP 800-115 provides a useful reference for structured technical-security testing and assessment planning.

6. Inspect the report before buying

Ask for a redacted sample report. It should separate executive and technical audiences, show reproducible evidence where appropriate, explain business context, prioritize remediation, and make it possible for engineers to act. A long vulnerability list is not automatically a good penetration-test deliverable.

7. Define remediation and retesting

Do not assume a retest is included. Clarify how many remediation-validation cycles are covered, the time window, whether new findings discovered during retesting are handled, and whether the final report shows verification status. This becomes especially important when the output supports audit or customer assurance.

Swedish and EU regulatory considerations

This section is general information, not legal advice. Applicability depends on the entity, system, activity, contract, and regulator. The status below uses primary-source research current to August 10, 2026 and should be rechecked immediately before reliance.

Sweden’s Cybersecurity Act and NIS2

Sweden’s Cybersäkerhetslag (2025:1506) entered into force on January 15, 2026. The law implements Sweden’s NIS2 framework and requires covered entities to manage cybersecurity risk systematically. The Swedish statute and NCSC guidance should be the starting points for applicability.

NCSC’s published implementation timetable states that incident and information regulations took effect on July 1, 2026. It also states that regulations on security measures and leadership training, plus rules concerning security audits and security scanning, take effect on October 1, 2026. As of August 10, that October date is still in the future. Organizations should therefore review the current NCSC timetable and scope guidance rather than rely on a static summary.

Neither this article nor the source baseline treats the Swedish Cybersecurity Act or NIS2 as an automatic rule that every covered entity must buy an external full-scope penetration test on a fixed schedule. Security testing can be part of risk-based technical validation, but the exact required measure depends on the applicable provision and circumstances.

DORA and threat-led penetration testing

The EU Digital Operational Resilience Act (DORA) contains specific threat-led penetration testing (TLPT) requirements in Articles 26–27 for financial entities identified under the applicable framework. The controlling sources are the DORA text and the TLPT regulatory technical standards in Delegated Regulation (EU) 2025/1190.

Do not equate DORA TLPT with a standard web, API, cloud, or infrastructure pentest. TLPT has its own applicability, scope, threat-intelligence, tester, control, and governance requirements. Not every Swedish financial organization should assume that it is automatically subject to TLPT; the entity must determine applicability under the current framework and competent-authority guidance.

GDPR Article 32

GDPR Article 32 includes a requirement, where appropriate, for a process to regularly test, assess, and evaluate the effectiveness of technical and organizational measures. It does not say that every controller or processor must purchase a penetration test. A pentest can be useful evidence in a risk-based security program, but it does not itself prove GDPR compliance, eliminate liability, or prevent enforcement.

PCI DSS v4.0.1

For environments in scope for PCI DSS, Requirement 11.4 contains penetration-testing requirements for applicable internal and external environments and related conditions. Buyers should use the current PCI SSC document library to verify exact scope, segmentation, significant-change, service-provider, methodology, and retesting requirements. Reducing PCI DSS to “one annual external test” is incomplete.

ISO/IEC 27001:2022

ISO/IEC 27001:2022 does not universally state that every certified organization must run a penetration test. Security testing may support risk treatment, vulnerability management, and assurance evidence, but applicability depends on the organization’s risks, controls, and management system. Do not reuse the legacy Annex A.12.6.1 numbering as if it were the current 2022 control structure; current vulnerability-management discussions commonly reference Annex A control 8.8 where relevant. Use the current ISO source or licensed standard text for exact wording.

Scope and cost drivers in Sweden

There is no defensible reason to invent a single “Swedish penetration-testing price” for this comparison. Quotes vary primarily with the work being authorized and the evidence required.

Common cost drivers include:

• number and complexity of applications, APIs, IP ranges, cloud accounts, identities, and environments;
• authenticated versus unauthenticated testing and number of user roles;
• web, API, mobile, network, wireless, cloud, social-engineering, or red-team scope;
• business-logic and manual exploit-validation depth;
• production-safety constraints and testing windows;
• required tester seniority or specialist skills;
• on-site travel, Swedish-language requirements, or security-clearance constraints;
• executive and technical reporting depth;
• framework mapping or audit-facing evidence requirements;
• remediation support and number/timing of retests; and
• one-off project versus recurring or PTaaS delivery.

Use a detailed statement of work and compare like-for-like scope. A general penetration testing cost guide can help identify cost variables, but the procurement decision should be based on the actual environment and deliverables rather than a headline market average.

Evidence to request before signing

Frequently asked questions

Which penetration testing company is best for a Swedish organization?

There is no universal best provider. DeepStrike is placed first in this DeepStrike-published editorial comparison, while Truesec, Outpost24, Orange Cyberdefense Sweden, Knowit, Sentor, CyberStrike AB, eBuilder Security, Cyloq, and Basalt each fit different procurement conditions. The right shortlist depends on technical scope, human testing depth, assigned testers, local requirements, reporting, remediation, retesting, data handling, and contracting constraints.

Should Swedish buyers choose a local provider or an international specialist?

Choose based on constraints and evidence. A local provider may simplify contracting, language, on-site work, or public procurement, while a cross-border specialist may fit a remote application, API, cloud, or advanced technical scope. Verify the actual tester location and data handling rather than using headquarters as a proxy for either technical quality or regulatory suitability.

What is the difference between vulnerability scanning and penetration testing?

Vulnerability scanning is primarily automated discovery. Penetration testing adds authorized human judgment and controlled exploitation to determine whether weaknesses are actually exploitable, how they combine, and what the practical impact is. Scanners are useful tools, but a scanner report should not be represented as equivalent to a full human-led pentest.

Does Sweden’s Cybersecurity Act require penetration testing?

The Cybersäkerhetslag (2025:1506) requires risk-based cybersecurity measures for covered entities, but it should not be summarized as a universal rule requiring every covered organization to buy an external penetration test on a fixed schedule. NCSC’s current rules and guidance, the entity’s classification, and its risk profile must be reviewed. This is not legal advice.

Does DORA require every Swedish financial company to perform TLPT?

No. DORA establishes TLPT requirements for financial entities identified under the applicable framework; it should not be generalized to every financial company or every DORA-regulated entity. TLPT is also a distinct exercise from a normal web, API, cloud, or infrastructure penetration test.

How much does penetration testing cost in Sweden?

Cost depends on asset count and complexity, authenticated roles, cloud/API/mobile/network scope, testing depth, safety restrictions, reporting, remediation, retesting, on-site requirements, and delivery model. This comparison does not invent a national price range. Ask multiple providers to quote the same written scope so that price comparisons are meaningful.

What should be included in a penetration-testing statement of work?

A useful statement of work should define authorization, in-scope and excluded systems, testing windows, accounts and roles, permitted techniques, stop conditions, escalation paths, evidence handling, reporting, remediation support, retesting, data retention, subcontracting, and required compliance or procurement outputs. The final rules of engagement should be explicit enough that both the tester and system owner understand the safety boundaries.

Conclusion

The strongest penetration-testing shortlist for a Swedish organization is the one that matches the actual technical scope and procurement constraints. Separate location from delivery evidence, separate scanning from human-led testing, and require proof about the assigned team, methodology, reporting, remediation, retesting, and data handling. Regulatory frameworks can shape the engagement, but they should be mapped precisely rather than used as generic sales claims.

DeepStrike is the first editorial selection in this DeepStrike-published comparison. If its cross-border, human-led model fits your requirements, review the current DeepStrike penetration testing service and compare the proposed scope against the same evidence checklist used above.
