Brazil’s thriving digital economy and strict data protection laws like the LGPD, Lei Geral de Proteção de Dados make cybersecurity a top priority for businesses. One key defensive measure is penetration testing hiring ethical hackers to simulate attacks and find vulnerabilities before criminals do.
In fact, the Brazilian General Data Protection Law encourages regular security assessments and penetration testing as part of compliance. This proactive approach is vital when the average cost of a data breach in Brazil now reaches about R$7.19 million US$1.4 million. Choosing a reliable penetration testing partner can save companies from financial losses, legal penalties, and reputation damage.
This article, written in the voice of Mohammed Khalil Cybersecurity Architect at DeepStrike, evaluates the top penetration testing companies in Brazil. We’ll explore what makes these providers stand out from the services they offer web, mobile, cloud, and API security testing to their compliance expertise in LGPD, PCI-DSS, SOC 2, and other standards.
We’ll also consider pricing models, industry specializations, and reputation. Whether you’re a Brazilian fintech startup needing red team services or an enterprise seeking cloud penetration testing in Brazil, this guide will help you identify a trustworthy partner.
For additional background on penetration testing, see our penetration testing services page. It explains how DeepStrike simulates real-world attacks to secure systems before it’s too late.
Not all pentesting providers are equal. Based on industry best practices and Google’s E-E-A-T principles Experience, Expertise, Authoritativeness, Trustworthiness, here are key criteria when evaluating penetration testing companies in Brazil:
For example, a provider should be comfortable testing everything from a corporate network to a fintech mobile app or an AWS cloud deployment. DeepStrike, for instance, provides web, mobile, infrastructure, and red team testing, and even a Continuous Penetration Testing program for ongoing security assurance.
In fact, PCI-DSS explicitly requires regular penetration testing PCI DSS Requirement 11 for in-scope systems. While SOC 2 doesn’t mandate pentests, auditors often recommend them as a best practice for demonstrating strong controls. The top companies align their work to global standards like OWASP Top 10 and NIST guidelines.
DeepStrike adheres to elite standards including OWASP, NIST, ISO 27001, and PCI-DSS, ensuring a thorough and methodical approach.
For example, DeepStrike’s team possesses globally recognized certifications and has members in Fortune 500 bug bounty Hall of Fame lists. Experience matters too firms that have tested across industries finance, healthcare, e-commerce, and the government will be better prepared to uncover complex vulnerabilities.
DeepStrike holds a 5.0 out of 5.0 rating on Clutch across 27 reviews, clients frequently praise its thoroughness, communication, and ability to find issues others missed. Similarly, Blaze Information Security is highly rated 4.8/5 for its technical expertise and detailed reporting.
When evaluating providers, check for such testimonials and ask for references. A proven track record in Brazil or globally is a good indicator of trustworthiness.
They may also include an executive summary for non-technical stakeholders. Ensure the firm offers support for re-testing fixes. Some like DeepStrike, even offer free unlimited re-testing to validate that vulnerabilities are properly resolved.
Good providers might also assist with mitigation guidance, developer debriefs, and compliance documentation like attestation letters for auditors.
Penetration testing cost in Brazil usually depends on the number of targets, complexity, and depth of testing. Typical engagements might range from a few thousand reais for a small app test to tens of thousands for comprehensive assessments.
Globally, a standard pentest can cost around $2,000–$10,000, whereas a highly in-depth test might go up to $50,000. Transparent companies will provide upfront quotes and help define a scope that fits your budget.
Be cautious of both extremes: very cheap offers which might just run automated scans and overly expensive ones that don’t provide commensurate value. Look for value: quality findings, timely delivery, and support should justify the cost.
Now that we know what to look for, let’s examine the top penetration testing companies in Brazil that meet these criteria. We’ll highlight each provider’s services, strengths, compliance focus, pricing approach where known, industry experience, and reputation.

What is penetration testing and why do businesses in Brazil need it?
Penetration testing or pentesting is a security exercise where ethical hackers simulate real cyberattacks on your systems to identify vulnerabilities. It’s essentially a proactive hack yourself before hackers do approach. Businesses in Brazil need pentesting to uncover security weaknesses in their websites, applications, networks, or APIs before criminals exploit them. With Brazil experiencing increasing cyber threats, phishing, ransomware, etc. and regulations like LGPD requiring strong data protection, pentesting helps organizations verify their defenses. By finding and fixing flaws early, companies avoid costly breaches, downtime, and compliance penalties. As one definition puts it, penetration testing is a method of evaluating security by simulating an attack from malicious outsiders or insiders. It's a critical practice for any serious cybersecurity program.
How often should we conduct penetration testing?
The frequency of pentesting depends on your environment and compliance needs, but general best practice is at least once a year. Many standards back this up for example, PCI-DSS requires annual penetration tests and after any major changes for companies handling credit card data. Even when not mandated, doing a pentest annually or bi-annually is wise because new vulnerabilities and system changes can introduce new risks over time. If your company deploys updates frequently e.g., a fintech releasing new app features monthly, you might opt for more frequent testing or continuous pentesting services. Critical infrastructure or high-threat targets could be tested quarterly. Ultimately, the schedule should be based on risk: high-impact systems deserve more frequent scrutiny. Remember, pentesting is a snapshot of security at a point in time. Regular testing ensures that security holes are caught and fixed on an ongoing basis, not just once in a blue moon.
What types of penetration testing services are most needed in Brazil?
Businesses in Brazil typically seek a range of pentesting services depending on their assets:
In summary, web, mobile, API, and network pentests are core needs, with cloud security and red teaming growing. Top providers in Brazil offer all these services to meet the country’s evolving security challenges.
How does penetration testing help with LGPD and other compliance requirements?
Penetration testing plays a crucial role in meeting various compliance and regulatory requirements, though the specifics vary:
In essence, penetration testing supports compliance by identifying gaps before an auditor or attacker does. It provides documentation you can show to regulators or clients that you’re taking due care to secure systems. Moreover, it helps avoid the ultimate compliance nightmare, a data breach that leads to fines or sanctions. Think of pentesting as proactive compliance: it’s easier to prove you meet security requirements when you have a report showing you tested and fixed vulnerabilities in advance.
How much does a penetration test cost in Brazil?
The cost of a penetration test in Brazil can vary widely based on scope and provider. For a small business wanting a basic test of a simple website, you might find local offerings in the R$10,000 to R$20,000 range roughly $2,000–$5,000 USD. More complex projects say a full network and application pentest for a mid-sized company could cost R$50,000+. Generally, penetration testing costs often range from $2,000 up to $50,000 USD for a single engagement depending on depth and targets. A high-quality test thorough manual testing, experienced team, detailed reporting tends to fall in the mid-to-upper end of that range. On average, globally, companies often pay around $10,000–$30,000 for a comprehensive test of a few applications.
In Brazil, local providers might be a bit more affordable than international ones, but be cautious with anything that seems too cheap. Ultra-low quotes e.g., a few thousand reais for a large scope could indicate the tester will just run automated tools without deep analysis which isn’t very helpful. Reputable firms will assess your needs and give a custom quote. Some variables that affect pricing include: number of IPs or applications in scope, complexity of the systems, whether source code review is included, and the level of reporting detail required e.g., for compliance. Also, if you need re-testing or multiple rounds of testing, that may influence cost although firms like DeepStrike include re-tests for free.
expect to invest a few thousand dollars for meaningful pentesting. Considering the potential cost of a breach, it’s a worthwhile investment. It’s always a good idea to discuss your budget and objectives with potential vendors. Most will tailor a proposal to maximize value for your budget.
What is the difference between a penetration test and a red team exercise?
Both penetration tests and red team exercises involve ethical hacking, but they differ in scope and goals:
In summary, a pentest is about breadth and depth in a scoped environment finding as many bugs as possible, whereas a red team is about realism and goal-oriented attack simulation. For many companies in Brazil, starting with penetration testing is sufficient to significantly improve security. Red teaming is typically for more mature organizations that have solid basics and want to rigorously test their holistic security often to benchmark their incident response or satisfy high-end compliance requirements like a critical infrastructure standard. Both are valuable; they just serve different purposes in a security program.
Will penetration testing disrupt our systems or business operations?
When performed by experienced professionals, penetration testing is designed to be safe and minimize disruption. Reputable pentesting companies in Brazil will typically schedule tests at convenient times and coordinate with your IT team to avoid critical periods. They often start with passive reconnaissance and then move to active testing carefully. For example, they might avoid running heavy vulnerability scans during peak business hours, or they might get explicit approval before testing on production systems that are very sensitive. Most tests, especially of applications, can be done without any noticeable impact on users. Network tests might cause minor spikes in traffic or trigger some security alerts, but that’s usually manageable. Before a test begins, you’ll have a planning meeting to outline rules of engagement you can highlight any stability concerns then.
In rare cases, exploiting a vulnerability can cause a system to crash for instance, if a buffer overflow is tested on a fragile legacy system. However, pentesters typically know how to identify such scenarios and either skip them or perform them in a controlled way. They might also use a staging environment if available. Overall, serious issues are uncommon. Think of it this way: a small risk of minor disruption during a planned pentest is far better than an unplanned real attack causing major disruption. The goal of the pentest team is to help you improve security, not create outages. With good communication between you and the testers, the process should be smooth. Many Brazilian companies undergo pentests regularly without their customers or operations ever noticing anything unusual.
Choosing the right penetration testing partner in Brazil can significantly bolster your cyber defenses. The top pentesting companies in Brazil like DeepStrike, Blaze Information Security, eSecurity, DM11, and Resh each bring something unique to the table, but all share a commitment to technical excellence and helping organizations stay secure and compliant. By evaluating providers against the criteria we discussed, services, compliance expertise, pricing, industry experience, and reputation, you can find a firm that fits your specific needs and culture.
Remember, penetration testing is not just a checkbox for compliance it’s an ongoing strategy to protect your business’s trust and data. The insights gained from a quality pentest will help you fix weaknesses before attackers find them, ultimately saving you money and headaches in the long run.
