Penetration testing used to be one of those audit boxes teams could tick with whatever security tooling they already had. That’s getting harder to defend. When an auditor asks what was actually tested, who tested it, and whether anyone proved an issue could be exploited, a scan report on its own may not get you very far.
That matters across SOC 2, PCI DSS, and HIPAA. Auditors increasingly want evidence of hands-on testing that connects back to the controls in scope. A thin report can trigger another round of questions and slow the audit down, while data breach monitoring still won’t answer an assessor asking for proof that someone actively tried to exploit a weakness. Below, we’ll look at what the major frameworks are pushing you towards, what to expect from a compliance-focused testing partner, and six firms worth considering.
TL;DR: the best compliance focused penetration testing companies are:
- CYBRI: Manual-first pentesting across web, mobile, API, cloud, network, and LLM targets, with audit-ready reporting mapped to SOC 2, ISO 27001, HIPAA, and GDPR.
- BreachLock: Penetration testing as a service that pairs human testers with an automated platform for on-demand and scheduled engagements.
- Cobalt: A PTaaS pioneer combining a vetted tester community with a platform built for fast kickoff and compliance-ready reporting.
- Synack: A managed model blending a vetted researcher network with continuous coverage, strong in government and regulated enterprise work.
- NetSPI: Enterprise-scale penetration testing for large, recurring programs across applications, networks, cloud, and attack surface management.
- Schellman: A licensed CPA firm whose assessor background gives its testing an auditor’s perspective on what evidence will hold up.
Why penetration testing carries more weight in compliance audits
Most cybersecurity compliance frameworks are asking companies the same question, and that is whether they’ve tested if their security holds up. The wording behind the requirements is different from one standard to another e.g., SOC 2 or HIPAA or ISO 27001. However, what each is fundamentally after remains the same.
For example, many of the frameworks don’t specifically list “penetration testing” as a requirement to be considered compliant. In practice though, penetration testing conducted by a third party is the best way to show an auditor that your access controls and monitoring work in real life.
The fact that there’s no written requirement leaves many teams thinking that a scan will satisfy their SOC 2, HIPAA, GDPR or other compliance requirements. Automated scans are quicker, cheaper and easier to run, but they won’t truly test whether your system holds up against an attack from a real hacker. That’s where manual-first testing comes in.
What separates a compliance-grade penetration testing partner
There’s no shortage of companies selling a ‘compliance pentest’. The more useful question is whether their work will stand up when an auditor starts asking for detail. A few things are worth checking before you sign anything.
First, look for genuine manual testing. Automation is valuable for breadth and speed, but the findings that matter most often come from someone thinking through how your particular product could be abused. That’s the part that looks more like ethical hacking than scanning: a tester notices an odd permission path, tries a different sequence of actions, and keeps digging until they know whether the weakness can actually be exploited.
Breadth matters as well. Modern environments rarely live in one neat layer, so the test may need to cover web and mobile applications, APIs, cloud configuration, and internal networks. A provider that only looks at one part of that picture can leave you with gaps. Experienced testers also recognize the common coding mistakes that seem harmless in isolation but become exploitable once they’re exposed in a live system.
Then there’s the report. It can feel like the least interesting part of the engagement right up until an auditor rejects it. A strong report should map findings to the controls that matter, explain severity in a way both engineers and assessors can follow, and include enough evidence to show what was actually demonstrated. Remediation guidance should be specific enough for your team to act on without deciphering vague security language.
Retesting matters as well. If you fix a critical issue, you want evidence that the fix was checked, not just a note saying the ticket was closed. Certifications such as OSCP, OSWE, GIAC, and CEH can also help you judge whether the people doing the work have gone through recognized technical vetting.
Those are the basics to look for before comparing providers. From there, the right choice comes down to the kind of environment you run, how often you need testing, and how closely the engagement needs to line up with an audit.
6 compliance-focused penetration testing companies worth considering
This isn’t a strict ranking, and the firms below don’t all deliver testing in the same way. Some lean heavily on platforms and recurring programs; others are closer to a traditional consultancy or audit firm.
1. CYBRI
Established in 2017, CYBRI is a New York-based penetration testing firm that focuses on manual, human-led penetration testing at the center of its work rather than treating a scan as the finished product. Its team tests web and mobile applications, APIs, cloud environments, networks, and AI systems, with engagements mapped to SOC 2, ISO 27001, HIPAA, and GDPR. Clients can manage ongoing testing through Blue Box, CYBRI’s reporting platform. Between manual penetration tests, CYBRI can provide continuous automated DAST, external attack surface monitoring, AWS and Azure configuration monitoring, and CI/CD pipeline alerts. Reports are built for audit and client use, with findings mapped to relevant compliance controls and remediation testing included.
If SOC 2 is driving the pentest, this piece on SOC 2 penetration testing services explains the scope, timing, and evidence auditors typically look for. It’s a strong fit for technology teams who want detailed manual testing without giving up ongoing automated coverage.
2. BreachLock
BreachLock combines human-led penetration testing with a platform built around on-demand and scheduled engagements. That setup works well if you don’t want security testing to be a once-a-year exercise. Its reporting supports common compliance frameworks, including SOC 2 and PCI DSS, and findings sit in a portal where teams can follow remediation and request retests. It makes the most sense for organizations that value fast turnaround and want a repeatable testing cadence managed through a platform.
3. Cobalt
Cobalt was one of the early companies to make penetration testing as a service, or PTaaS, a mainstream model. It pairs a vetted community of testers with a platform that handles scoping, communication, and reporting. Engagements can cover web and mobile applications, APIs, cloud environments, and networks, with reporting structured for compliance needs such as SOC 2 and PCI DSS. Cobalt is likely to appeal to product teams that want to start tests quickly and feed findings back into an active development process.
4. Synack
Synack takes a managed approach, combining its testing platform with a vetted network of security researchers and ongoing coverage. It has a significant presence in government and regulated enterprise environments, where detailed assurance and traceability matter. The platform keeps a clear record of testing activity, which can be useful when an assessor wants to know exactly what was tested and when. This model is well suited to enterprises and public-sector organizations with demanding reporting and assurance requirements.
5. NetSPI
NetSPI is geared towards larger penetration testing program. Its platform supports recurring work across applications, networks, cloud environments, and attack surface management, which makes it easier to coordinate testing when you have a lot of assets in scope. Reporting and remediation tracking are designed to work at that scale without stripping away the detail auditors may ask for. It’s best suited to larger organizations with mature security programs and a broad, complex environment to test.
6. Schellman
Schellman comes at penetration testing from a slightly different angle. It’s a licensed CPA firm with a long-standing compliance assessment practice, so its testing work benefits from an assessor’s perspective. Because Schellman also performs SOC 2 and ISO 27001 audits, its teams are familiar with the type of evidence auditors expect and how findings need to be presented. Testing covers applications, networks, and cloud environments. It can be a sensible choice for organizations that want the penetration test to fit very closely into the audit process.
All six firms can produce more than a basic scan report. The real differences are in how they deliver the work, the scale they’re built for, and how tightly the testing process connects to your wider compliance programme.
Choosing the right provider
One useful way to judge a provider is to imagine your auditor reading the final report. Does it answer the obvious questions, or does it create a new list of questions for them?
Start with your framework and your environment. A fintech company handling card data will have different priorities from a health tech platform working under HIPAA, while a SaaS team shipping changes every week may need a different testing cadence altogether. Ask to see a sample report before you commit and pay attention to how findings are mapped to controls. Don’t compare price without comparing depth: a cheap scan can become expensive if it creates extra audit work later. Make sure retesting is included, and confirm that the scope reaches every part of the environment that matters to the audit, from APIs and cloud configuration to everyday controls such as multi-factor authentication on privileged accounts.
Get those decisions right and the penetration test becomes useful beyond the security team. Instead of scrambling for evidence at audit time, you already have a report that shows what was tested, what was found, and whether the important fixes held up when they were checked again.
