Protagonist follows globally recognized methodologies. Every finding is mapped to industry benchmarks, so your reports carry weight with investors, auditors, and clients.
OWASP Testing Guide
Security standards, mapped to OWASP Top 10 risks.
NIST SP 800-115
U.S. federal standard for technical security testing.
PTES
End-to-end methodology for penetration testing.
We uncover risks that automated tools miss, deliver compliant-ready reports, and help your team fix issues fast.
Vulnerability assessments
We scan your apps and cloud to find weak spots before attackers do. Every finding is prioritized by risk, tied to business impact, and tailored to your technology stack.
Penetration testing
Our certified ethical hackers simulate real attacks on your systems, covering OWASP Top 10 risks and more. You receive a detailed report mapped to your target framework.
Cloud & app testing
From AWS, GCP, and Azure settings to mobile and web apps, we test all layers, not just the surface. We identify misconfigurations, insecure code, and potential attack paths.
Remediation support
Our experts can help implement fixes in your backend, architecture, or CI/CD pipelines. Retesting is included to ensure vulnerabilities are fully resolved.
Compliance-ready reporting
Reports are tailored for SOC 2, ISO 27001, HIPAA, GDPR, and other standards, with a roadmap of risks and CVSS-based recommended fixes.
What our clients are saying about us
Protagonist empowers teams to build with confidence, ensuring every product is secure, compliant, and ready to scale.
“The issues they found were clearly relevant to our production environment and were explained in a way that made them easy to prioritize.”
“The project was well-managed from start to finish. What stood out most was their ability to combine deep technical expertise with a pragmatic and business-oriented approach.”
“Their deep expertise in cybersecurity, particularly in the context of modern software architecture, was outstanding.”
“We were impressed by Protagonist’s deep expertise, hands-on experience, and strict delivery processes.”
“Protagonist has delivered a clear list of compliance-related improvements, which we have implemented. The team has provided valuable recommendations, giving us a better understanding of how to handle security and privacy topics in future software releases. They work independently.”
In 4 stages, we uncover vulnerabilities, prioritize them by risk, and provide compliance-ready reports. Every step is hands-on and tailored to your product and business logic.
Step 1
Duration: 2–6 weeks
Vulnerability assessment
& penetration testing
We start with a CVSS-based vulnerability assessment and manual penetration testing. Our tests are mapped to OWASP top 10 risks and your compliance frameworks. We provide cloud, web and mobile app testing.
Step 2
Delivery: Joint workshop
Reporting
Our reports include an executive summary and a technical section outlining vulnerabilities and remediation steps. They can be used for compliance, investor diligence, or as a security white paper to gain customer trust.
Step 3
Delivery: ongoing
Remediation support
We provide support for security fixes and retesting to validate the success of the changes. Besides, our DevOps and security experts can implement changes directly in your backend, architecture, or CI/CD pipelines.
Step 4
Delivery: on demand
Continuous monitoring &
reassessment (optional)
We scan your systems, reassess risks, and conduct retests after infrastructure changes. We also support regular security tests to meet compliance requirements.
We identify vulnerabilities others miss, provide remediation guidance, and ensure your product meets the compliance standards.
High-quality testing
Our certified experts go beyond tools, testing every layer of your system, including web, mobile, APIs, and cloud configurations. We simulate real-world attacks to identify risks that could impact your clients.
Compliance-ready reporting
We deliver reports tailored to your compliance needs, providing detailed descriptions of vulnerabilities mapped to your target frameworks.
Broad expertise pool
We can adapt to a wide range of tech stacks, providing niche experts to find vulnerabilities and implement fixes in backend systems, CI/CD pipelines, and cloud infrastructure.
Transparent subscription
We offer subscription-based vulnerability assessments for routine coverage, regular penetration tests, and retesting after major infrastructure or product changes.
Here’s how Protagonist helps clients discover hidden vulnerabilities, validate security, and strengthen their products.
In just a few months, your systems go from vulnerable to fully assessed,
secure, and ready to prove safety to clients and investors.
Ready to start your journey?
Automated scans miss real risks, and internal teams lack attacker expertise. Our certified experts use proven methods and full hands-on testing to ensure real security and resilience.
What you need | Protagonist | Internal Teams | Automated platforms |
|---|---|---|---|
| Manual testing expertise | Certified ethical hackers perform deep penetration tests | Often limited by time or familiarity with your product | Only automated scans that miss complex issues |
| Full coverage | Web, mobile, cloud, and business logic all tested | Often partial testing or reactive fixes | Superficial scanning that misses cross-system vulnerabilities |
| Audit-ready reporting | Reports mapped to SOC 2, ISO 27001, HIPAA, GDPR, and more | Incomplete or inconsistent documentation | Generic outputs that are not ready for audits |
| Flexible expertise | Can adapt to any tech stack using our broad expert pool | Limited to in-house skills | Cannot adjust, rigid scope |
| Work with us |
Our testing services are designed for SMBs who need fast and credible results. We offer flexible subscription options based on what you need: vulnerability assessments, penetration tests, or ongoing scanning.

No. We only begin after signing a contract that clearly defines the rules of engagement. Tests are run in staging or non-production environments. If we uncover a vulnerability that could cause real harm, we pause immediately and notify you, so nothing proceeds without your approval.
You’ll receive a detailed report with findings prioritized using the CVSS scoring system, so you know exactly what to fix first. We also include a presentation session to walk through the results, answer questions, and make sure everything is clear. In addition, remediation support is part of the package — our team guides your developers through fixes and verifies that risks are fully resolved.
Our goal isn’t just to deliver a report. The real purpose of security testing is to help you close security gaps and make your systems genuinely more secure.
We rely on internationally recognized standards:
This ensures your test results are credible, consistent, and recognized by auditors.
Many testers only know how to “break things” but lack experience with modern frameworks and development practices. Our team combines deep security expertise with hands-on software engineering knowledge, so we can test your product realistically and give developers fixes they can actually implement.
Yes. Many frameworks like HIPAA, GDPR, PCI DSS, SOC 2 require penetration testing. We map every vulnerability we find to the relevant compliance requirement. You’ll get a tailored compliance report showing which issues matter most for your certification.
Absolutely. We adapt the scope and methods to your needs, whether it’s web apps, mobile, APIs, or cloud infrastructure. You get the right coverage for your product, never a generic “checklist” scan.
Yes. We can run a test within a week if needed. You’ll receive an independent report confirming your systems are secure, or highlighting vulnerabilities. If issues are found, we can help remediate them quickly and provide a free retest to validate the fixes.
No. We only begin after signing a contract that clearly defines the rules of engagement. Tests are run in staging or non-production environments. If we uncover a vulnerability that could cause real harm, we pause immediately and notify you, so nothing proceeds without your approval.
