A complete guide to Germany’s leading cybersecurity firms, pentesting specialists, and regulatory drivers.
Mohammed Khalil

The top cybersecurity companies in Germany for 2026 include BSI-certified penetration testing providers SySS, Secuvera and Deutsche Telekom Security; offensive specialists Cure53, Code White, NSIDE Attack Logic and Pentest Factory; and product vendors secunet, G Data, Utimaco, genua, Rohde & Schwarz Networks and Cybersecurity, Hornetsecurity, Link11, Myra Security, Greenbone, SoSafe and infodas. DeepStrike, the publisher of this guide, tests remotely and is listed with a disclosure. Bitkom forecasts German IT security spending of €14.3 billion in 2026. Shortlist by need: certified testing, managed detection, or a security product.
Germany’s Mittelstand faces persistently high levels of cyber threats. In 2024 police recorded ~131,000 domestic cybercrime cases plus about 202,000 committed from abroad (roughly 333,000 in total), and the BKA Bundeslagebild Cybercrime 2025 (published May 2026) counts roughly 335,000 cybercrime offences for 2025, similar to 2024, about two thirds of them committed from abroad or unknown locations, plus 1,041 reported ransomware attacks, up about 10% on 2024. Federal officials warn that AI enabled phishing and nation state tactics are making breaches more sophisticated. New EU and national regulations like NIS2 and DORA are forcing companies to prove defenses. Germany’s NIS2 implementation act took effect on 6 December 2025, expanding the BSI Act’s scope from about 4,500 regulated organizations to roughly 29,500 supervised entities and making cybersecurity a management board responsibility. In finance, DORA now mandates threat led penetration tests TLPT for financial entities that competent authorities designate for TLPT.
Comparing providers beyond Germany? Our list of the top penetration testing companies worldwide covers firms that deliver testing across regions. For neighboring markets, see our guides to penetration testing companies in Poland and the Czech Republic. Buyers with UK operations can compare cybersecurity companies in the UK by category, from MDR providers to testing firms.
Disclosure: DeepStrike, the publisher of this guide, is a penetration testing provider and is included in this list. Weigh our entry the way you would any vendor's description of its own service, and compare scope, sample reports and references for every provider before you buy.
For a German-language comparison of penetration testing providers, see Führende Penetrationstest-Anbieter in Deutschland.
Against this backdrop, choosing the right cybersecurity partner is critical. German firms often demand providers with local presence and domain expertise familiarity with BSI standards, KRITIS, TISAX, and GDPR is a differentiator. This list is a research-driven selection, published by DeepStrike (which is also listed), of leading German cybersecurity companies. We focus mainly on German-headquartered specialists with German delivery teams and certifications, and also include providers headquartered elsewhere that serve German clients remotely, such as DeepStrike. We have applied the same rigorous criteria to all vendors: deep technical expertise, certified teams, wide service scope, industry experience, compliance readiness, transparent reporting, and client trust see methodology. Editorial note: DeepStrike publishes this guide and is included in it, so weigh its entry accordingly.
For penetration testing in particular, see Penetration Testing Services in Germany.
Germany’s cyber risk landscape is intensifying. The BKA counted roughly 335,000 cybercrime offences and 1,041 reported ransomware attacks in 2025, even as regulators rolled out NIS2, DORA, and stricter GDPR enforcement. Traditional testing models are evolving: many buyers move from one off scans to continuous testing platforms. For procurement, the stakes are high: a well scoped pentest costs a fraction of a multi million euro breach. This guide helps German CISOs and procurement teams compare the top vendors side by side, focusing on real differences e.g. technical depth vs. marketing hype so you can shortlist the right provider for your needs.
Selecting a cybersecurity partner in 2026 requires cutting through buzzwords. Common mistakes include trusting marketing over substance e.g. AI powered scanners with no proof and overlooking practical red flags. Red flags include vendors lacking certified experts e.g. CISSP, OSCP or formal accreditations BSI, ISO/IEC 27001, vague deliverables, or no local German speaking support. Avoid relying on pure scanning tools, instead emphasize human led expertise aligned with penetration testing best practices.
We evaluated firms on nine key criteria, each grounded in cybersecurity best practices:
This methodology ensures an E-E-A-T approach expertise, experience, authority, trust in our profiles. We applied the same criteria uniformly, including to DeepStrike, which publishes this guide, to keep the analysis buyer focused.
Providers are not scored or ranked; DeepStrike appears first because it publishes this guide (disclosed above), and the list order is not a quality ranking.

The eleven profiles above lean toward testing and assurance. Many buyers searching for cybersecurity companies in Germany want a product instead: a firewall, an email filter, DDoS protection or an awareness platform. The eight German-headquartered vendors below are widely used in those categories. We have not profiled them in depth or tested their products; each entry restates what the company or its owner publishes, checked on 5 November 2026, and the alphabetical order is not a ranking.
| Company | Category | Headquarters | What to know (checked 5 Nov 2026) |
|---|---|---|---|
| genua | Firewalls, high-security gateways and VPN for government and industry | Kirchheim near Munich | Part of the Bundesdruckerei group; its products carry BSI certifications and approvals. |
| Greenbone | Open-source vulnerability management (OPENVAS) | Osnabrück | Founded 2008; a stock corporation (AG) since 2023; ISO 27001 certified since 2021. |
| Hornetsecurity | Cloud email security, backup and security awareness for MSPs and SMBs | Hanover | Proofpoint completed its acquisition on 8 December 2025; Hornetsecurity runs as a dedicated Proofpoint business unit. |
| infodas | Cross-domain security gateways, consulting, audits and penetration tests for the public sector and defense | Cologne | Airbus subsidiary since September 2024; Airbus states its SDoT gateways are approved for classified information up to SECRET. |
| Link11 | DDoS protection, web application and API protection, secure CDN and DNS | Frankfurt am Main | Founded 2005; BSI-qualified DDoS mitigation provider; ISO 27001 and BSI C5. |
| Myra Security | DDoS mitigation, WAF, bot management and secure DNS as a service | Munich | Founded 2012; BSI-qualified DDoS mitigation provider serving banks, government and critical infrastructure. |
| Rohde & Schwarz Networks and Cybersecurity | Network and security hardware, firewalls, network encryption and zero-trust endpoint security | Würselen | Formed in 2026 from LANCOM Systems and Rohde & Schwarz Cybersecurity; the new name applies since 1 July 2026. |
| SoSafe | Security awareness training and phishing simulation | Cologne | A dedicated human-risk platform; compare it with the awareness modules that email security vendors bundle. |
A product vendor rarely tests its own customers' environments independently, so most organizations pair products with a separate testing partner. Link11 and Myra Security address availability attacks; our DDoS attack statistics show current attack trends. SoSafe and Hornetsecurity target the human layer described in our guide to social engineering. Greenbone's scanning complements, but does not replace, manual testing; see how a vulnerability assessment differs from a penetration test.
Germany's IT security market is forecast to grow 11.7% to €14.3 billion in 2026, up from €12.8 billion in 2025, and to pass €15 billion for the first time in 2027 at €15.8 billion, according to Bitkom's 28 October 2026 forecast based on IDC data. Software accounts for €7.8 billion, or 55% of 2026 spending, covering endpoint and cloud protection, identity and access management, and attack detection. Services such as consulting, integration and managed security add €5.3 billion, and security hardware €1.2 billion.
| Segment | 2026 spending | Change vs 2025 | 2027 forecast |
|---|---|---|---|
| Security software | €7.8 billion | +14.5% | €8.9 billion (+14.6%) |
| Security services (consulting, integration, managed security) | €5.3 billion | +7.3% | €5.7 billion (+8.4%) |
| Security hardware (firewalls, appliances) | €1.2 billion | +14.6% | just under €1.2 billion (-4.2%) |
| Total | €14.3 billion | +11.7% | €15.8 billion (+10.7%) |

The same Bitkom release cites its Wirtschaftsschutz 2026 study: data theft, espionage and sabotage cost the German economy at least €211 billion a year, and 76% of that damage comes from cyberattacks. Regulation adds pressure. Germany's NIS2 implementation act brought roughly 29,500 entities under BSI supervision, and the EU Cyber Resilience Act adds security duties for products with digital elements. Even so, companies still spend 18% of their IT budgets on security, below the 20% that Bitkom and the BSI recommend. Our NIS2 penetration testing guide explains what testing evidence supervised entities should keep.
Reading market figures: commercial market reports quote different totals for the German cybersecurity market because they use different definitions, currencies and segment boundaries. Bitkom's October 2025 forecast, based on PAC data, put 2025 at €11.1 billion; the 2026 release uses IDC data and restates 2025 at €12.8 billion, so compare years only within one series. For buyers, the split matters more than the total: most spending goes to products, which is why this guide lists product vendors next to testing and managed-service providers.
Enterprises that need broad, 24/7 coverage usually fit large providers with global reach, multinational SOCs, and consulting arms that can handle complex procurement and compliance. SMBs and Mittelstand firms usually need agility and cost effectiveness, so specialized or local boutiques, configurable testing providers, or subscription-based PTaaS models often fit them better.
Large enterprises and smaller firms have different priorities. Enterprises often require broad, 24/7 security coverage. They lean toward providers with global reach, multinational SOCs, large consulting arms. For example, a major bank might choose a legacy firm or telco giant like T Systems or IBM that offers integrated SOC services, IR teams, and vendor agnostic consulting. These firms handle complex procurements and compliance e.g. Basel III, BaFin. They can invest in full time programs and may require certifications ISO/IEC 27001, NIS2 implementation support. Large companies also value ecosystem: a vendor supporting their chosen cloud AWS/Azure, or one that speaks enterprise lingo.
By contrast, SMBs or Mittelstand usually need agility and cost effectiveness. They often choose specialized or local firms. Boutiques such as NSIDE or Code White, or remote specialists such as DeepStrike, can suit smaller buyers that want a focused team; compare sample reports and references. For example, a tech startup or mid market manufacturer might prefer a configurable provider such as Pentest Factory for straightforward vulnerability testing rather than a bloated RFP process. SMBs might also opt for subscription based models PTaaS to stretch budgets, or rely on endpoint/security vendors like G Data rather than building in-house teams.
The trade offs come down to cost vs. value. Big consultancies offer wide service libraries but at high rates and with fixed contracts. Boutique firms provide personalized service and specialized expertise at potentially lower cost, but may lack on-call capacity or broad threat intel. For instance, a multinational firm may need a heavy duty SOC integration from a Telekom or IBM, whereas a 200 employee manufacturing company might prioritize rapid pentest turnaround and regulatory advice e.g. GDPR/TISAX guidance from a dedicated German cybersecurity firm. Ultimately, buyers should map their use case and scale to the provider’s strengths: ongoing managed services and strategic consulting for large orgs versus focused project work and tactical agility for smaller ones. Considering your organization’s size, industry, and maturity will guide this choice.
Pentest pricing varies widely by scope and depth. In Germany most consultancies quote per tester day, and the number of days depends on the size of the application or network in scope. For specialized testing e.g. red teaming or IoT security, rates can go higher. Continuous or subscription models PTaaS often use fixed bundles to provide predictable budgeting. Note: Investing in quality can save far more than the cost of a breach.
In practice, expertise trumps tools. A seasoned pentester with OSCP/CISSP and hands-on experience will find complex vulnerabilities that automated scanners miss. Tools are important for efficiency, but a human analyst’s skill is crucial. We looked for providers with recognized certifications and a track record of manual testing.
A traditional on site pentest e.g. web app test might involve 1–3 weeks of effort plus reporting. However, many firms now offer fast mobilization 48–72 hours and shorter cycles by running tests in parallel or continuously over a month. Model matters: with PTaaS, you often get incremental findings in real time rather than waiting for a final report.
Look for clarity and actionability. A good report has an executive summary business impact and risk level for non technical stakeholders, detailed findings with evidence: screenshots, steps, code, and remediation advice. It should classify issues e.g. OWASP ratings and include things like CVE references. Many German CISOs also expect attachments like network diagrams or compliance checklists.
At minimum, companies should test annually or after major changes, new app versions, merger, etc.. However, continuous testing is becoming best practice: many firms now run rolling vulnerability scans or employ PTaaS for ongoing coverage. For regulated sectors, DORA requires financial entities to test ICT systems that support critical or important functions at least yearly and requires threat led penetration testing every three years for designated firms, while NIS2 requires risk based measures including procedures to assess their effectiveness. Critical systems may warrant even more frequent testing, e.g. quarterly.
There are pros and cons. Local vendors often speak German, understand domestic regulations BSI/KRITIS, GDPR by default, and ensure data sovereignty. If these factors are crucial as they are for many German public and Mittelstand clients, local providers have an edge. Conversely, international firms may bring broader threat intelligence or global experience. In practice, many German firms use a blend: core testing by Germany based consultants, supplemented by global intel services.
It depends on what you are buying. For certified penetration testing, the BSI's provider list names SySS, Secuvera, secunet's test laboratory and Deutsche Telekom Security from this guide, and Cure53, Code White, NSIDE Attack Logic and Pentest Factory are offensive specialists.
