7 Best Penetration Testing as a Service (PTaaS) Providers in 2026

The old way of buying a penetration test went something like this. You signed a contract, waited weeks for a testing window, and then received a long PDF that was out of date by the time your team read it. For companies that release new code every week, that model no longer works.

Penetration testing as a service, or PTaaS, fixes much of that. Tests are easier to book, results show up in an online dashboard as they are found, and your team can talk to testers while the work is still going on. Retests are simpler too. Below are seven PTaaS providers worth considering, with a clear look at how each one works.

What Makes a Strong PTaaS Provider

The word "platform" gets used a lot, so it helps to know what actually matters:

• Real people doing the testing. A nice dashboard means little if the testing behind it is mostly automated.
• Live findings. You should see confirmed issues during the test, not only at the end.
• Easy collaboration. Your developers should be able to ask questions and assign fixes in one place.
• Simple retesting. Checking a fix should not require a whole new contract.
• Predictable cost. Clear pricing helps you test more often without budget surprises.

1. Cybri

Cybri offers penetration testing as a service backed by a team that has done nothing but offensive testing since the company launched in New York in 2017. Many PTaaS vendors started as software companies and added testing later. Cybri went the other way. Testing expertise came first, and the platform was built to support it.

That platform is called Blue Box. Once a test starts, you can follow its progress in real time. Each finding is checked by a tester before it appears, so your team is not buried in false alarms. From the dashboard, you can assign issues to engineers, discuss details with the testers, and track what has been fixed. When the test wraps up, the platform produces two reports: a summary for executives and a detailed technical version for developers.

The people behind the platform are the Cybri Red Team. Testers hold certifications such as OSCP, OSWE, and CEH, and many have worked in military cyber units or large enterprise security teams. Each test is run by one or two dedicated testers, which means you deal with the same people from start to finish instead of a changing crowd.

Cybri's PTaaS covers web apps, mobile apps, APIs, internal and external networks, and cloud setups on AWS, Azure, and Google Cloud. It also tests large language model features, which more companies now need as they add AI to their products. Results can be mapped to SOC 2, HIPAA, PCI DSS, ISO 27001, GDPR, and ISO 42001.

Pricing is fixed for each test, and a 90-day remediation check is included. Companies that want regular coverage can buy an annual package of several tests, which fits teams that ship often and need to recheck their security after big releases.

Best for: Companies that want the convenience of a PTaaS platform with certified, manual-first testers doing the real work.

2. Cobalt

Cobalt was one of the early companies to popularize the PTaaS model. Its platform connects clients with a network of vetted freelance testers and makes it quick to set up a new engagement.

The platform has strong integrations with developer tools, so findings can flow into ticketing and chat systems your team already uses. This makes it a common choice for engineering-driven companies.

Best for: Development teams that want pentest results inside their existing tools.

3. NetSPI

NetSPI delivers PTaaS through its own platform, backed by a large in-house team of testers. Beyond pentesting, it offers attack surface management and breach simulation.

The firm tends to work with bigger organizations that have many applications and large networks. Smaller companies may find its offering more than they need.

Best for: Enterprises that want PTaaS as part of a larger security testing program.

4. Astra Security

Astra pairs manual testing with a built-in vulnerability scanner that keeps running between tests. Everything sits in one dashboard where teams can see scan results, pentest findings, and fix progress.

Its setup is simple, which makes it appealing to startups and small teams without a dedicated security person.

Best for: Small teams that want scanning and testing in one simple tool.

5. BreachLock

BreachLock's PTaaS model combines automated tools with human testers and focuses on making repeat testing affordable. Reports are available through its online portal.

Many of its clients use it to meet recurring audit needs, since the process is built to be run on a regular schedule.

Best for: Companies that need frequent, lower-cost testing for audits.

6. Intigriti

Intigriti is a European security platform best known for bug bounty programs. It also offers hybrid pentesting, where researchers from its community test within a set time and scope.

It can be a good match for companies that want to start with a structured pentest and later open a bug bounty program on the same platform.

Best for: Teams, especially in Europe, that may want bug bounty and pentesting together.

7. Pentera

Pentera takes a fully automated approach. Its platform runs safe attack simulations across your network to show how an intruder could move from one system to another.

It works well for frequent internal checks, but automated testing is best used alongside human-led pentests rather than instead of them.

Best for: Security teams that want automated validation between manual tests.

How to Compare PTaaS Providers

1. Ask who does the testing. Find out whether tests are run by in-house staff, freelancers, or mostly software.
2. Try the dashboard. Request a demo and see whether it would actually help your developers.
3. Check how retests work. Some providers include them, while others charge extra.
4. Look at the reports. You want something leadership can understand and engineers can act on.
5. Think about frequency. If you release often, choose a provider that makes regular testing easy and affordable.

Final Thoughts

PTaaS has made penetration testing faster, clearer, and easier to fit into how modern teams work. The key is to remember that the platform is only as good as the testers behind it. Cybri stands out by pairing a transparent, real-time platform with certified testers, fixed pricing, and follow-up checks included. The other providers on this list suit different needs, from large enterprise programs to fully automated testing.
