Penetration testing as a service (PTaaS) put the annual pentest on a platform: findings appear live, retests are a click, and coverage tracks your release cycle. The label now covers everything from a crowd of freelance testers to an automated scanner with a subscription, so comparing PTaaS companies means looking past the dashboard at who does the manual testing and how you pay for it. This list does that.
This list is written by a penetration testing company, so Invadel is first and this is our site. Every other firm is described only from what it states on its own public pages, checked in September 2026. No prices for other firms appear here. If you want the definition of the model rather than a vendor list, start with our explainer on what PTaaS is. For the general market beyond the subscription model, see the best penetration testing companies.
What separates a real PTaaS from a scanner with a login
The dashboard is table stakes. Four questions decide whether a PTaaS gives you a penetration test or a scan on a subscription:
- Who performs the manual testing, and are they employees? A crowd, a rotating pool, or a named in-house team are three very different answers, and they change what the tester knows about your environment from one window to the next.
- How do you pay? Credits, seat licenses, or a fixed program price. Where credits do not roll over, testing time you paid for and did not schedule is lost at the end of the contract year.
- Is retesting genuinely included, or capped? Some retests are automated rescans, some are limited to a number of rounds, and some close after a window.
- What does the contract promise a human will do? Look for tester days or named scope coverage in writing. If the only commitment is access to a platform, you are buying a tool.
Our pentest platform alternative page lays out these questions in full, and the autonomous penetration testing vendors list covers the tools-only end of the market, which is a different buyer.
How we judged
Five criteria, in the order they affect what you get:
- Who tests: in-house employees, a vetted crowd, or automation with human review.
- Pricing model: fixed program price, credits, or seat license.
- Retesting: included and rolling, or capped and metered.
- Manual depth: real manual testing of authorization and business logic, not just scan output on a dashboard.
- Platform and integrations: live findings and pushes into Jira, Slack, Teams or ServiceNow.
The comparison table records what each firm states on its own public pages. “Not stated” means we did not find it there, not that the firm does not do it, so ask.
PTaaS companies in 2026
1. Invadel
Best for: teams that want senior, manual-first testing delivered as a program at a fixed price, without credits.
Our penetration testing as a service program is the reverse of a platform sale. Senior in-house testers, the same people at every window, do the work, and the platform is included at no extra cost. Manual test windows are scheduled around your releases and audits, analyst-validated scanning covers the months between, and every finding is tracked live until a retest confirms the fix. The program price is fixed in writing up front and built from our published fixed-scope tests, for example a web application test from $5,200 and an external network test from $4,200, with validated scanning from $1,500 per scan. No credits, no seat licenses, no rotating testers. You can read a sample report before you talk to us.
The honest limitation: we are a boutique. If you need dozens of applications tested in parallel every month across a global enterprise, a larger bench or a platform further down this list may fit the volume better.
2. Cobalt
Best for: buyers who want to launch tests quickly through a large freelance community.
Cobalt describes an “elite community of freelance pentesters” it calls the Cobalt Core, matched to engagements through its platform, and says PTaaS engagements take days to mobilize. It sells testing on a “credit-based subscription model”: credits come in annual packages, can be spent on any mix of testing services, and do not roll over into the next contract. It lists more than 50 native integrations, issues letters of attestation, and states that its PTaaS model provides “unlimited on-demand retesting throughout your contract term.” See our Invadel vs Cobalt comparison for how the credit model compares with a fixed program price.
3. NetSPI
Best for: large enterprises wanting a deep in-house bench across many testing disciplines.
NetSPI describes shifting “projects to programs” through “The NetSPI Platform,” and emphasizes “350+ in-house pentesters” who are “employed, not outsourced.” It offers live interactive vulnerability reports, remediation testing, and an open API into asset, IAM, ticketing and vulnerability systems, across application, cloud, network, hardware, mainframe and AI testing. On September 2, 2026, NetSPI and Synack announced they plan to merge, with closing expected in October 2026. See Invadel vs NetSPI.
4. Synack
Best for: enterprises that want a vetted researcher community plus AI triage through a platform.
Synack describes itself as an “AI and human powered pentesting platform” that combines Sara AI Pentesting, the Synack Red Team of vetted researchers, and the Synack Platform for “continuous, trusted security testing at scale.” It says it filters out noise so you receive only verified vulnerabilities, and lists web application, host, cloud and API testing. Note the announced NetSPI merger above. See Invadel vs Synack.
5. HackerOne
Best for: teams that already run a bug bounty and want pentests on the same platform.
HackerOne describes “H1 Pentest” combining “top-tier talent with AI-driven insights,” drawn from a “vetted pool of elite pentesters” matched to your stack. It offers real-time findings on the platform, integrations with GitHub, Jira, Slack and ServiceNow, retesting to confirm fixes, and reports aimed at SOC 2, ISO 27001 and GDPR evidence. See Invadel vs HackerOne.
6. BreachLock
Best for: buyers who want AI-assisted testing with in-house testers and fast turnaround.
BreachLock describes expert-led testing with “agentic AI-powered acceleration,” in which an autonomous engine handles reconnaissance so its testers, which it describes as 100% in-house, can focus on business logic and complex attack paths. It says tests launch in 24 to 48 hours through the BreachLock Unified Platform, with unlimited one-click automated retesting at no additional cost, a full manual retest, and audit-ready reports mapped to SOC 2, PCI DSS, ISO 27001, HIPAA and HITRUST. See Invadel vs BreachLock.
7. Bugcrowd
Best for: teams that want to buy and launch a crowd-sourced pentest in a few clicks.
Bugcrowd describes PTaaS delivered “through the cloud,” with testing teams curated by its CrowdMatch AI technology and the ability to launch standard or customized testing “in less than 72 hours.” It offers a dashboard showing findings and pentester progress 24/7, 12 months of retesting with one report update on its Standard and Plus tiers, and reports aimed at PCI DSS, SOC 2, HIPAA and ISO 27001 requirements. See Invadel vs Bugcrowd.
8. Fluid Attacks
Best for: engineering teams that want continuous testing wired into the CI/CD pipeline.
Fluid Attacks describes “continuous in-depth assessments by our pentesters,” combining manual testing with its own tooling (SAST, DAST, SCA and more) in one platform. It offers reattacks to check remediation and says it can break the build in your CI/CD pipelines to stop unsafe deployments. Its PTaaS page does not say whether the testers are employees, so ask. A strong fit when you want security gates inside the development workflow rather than a periodic report.
9. Software Secured
Best for: SaaS companies that want dedicated testers aligned to release cycles.
Software Secured describes PTaaS as “ongoing, manual pentests aligned to release cycles” with unlimited retesting, performed by dedicated Canadian pentesters it says are “never contractors.” Findings live in its own portal, which integrates with Slack, Jira, Azure DevOps and compliance tools such as Drata and Vanta. It positions the service around proving SOC 2 controls to auditors and customers. See Invadel vs Software Secured.

Use the “Not stated” and “No” cells as your question list for the vendor call. The two columns that change the economics most are who tests and whether pricing is fixed or metered.
Platform PTaaS vs a fixed-price team
The market splits along one line. On one side, the platform is the product and testing is attached to it, sold as credits or seats, often with a crowd or a rotating pool doing the work. On the other, senior testing is the product and the platform is included, sold at a fixed program price with the same team every window.
Neither is automatically better. A platform with a large crowd scales to many assets fast and suits an enterprise with constant, high-volume needs. A fixed-price in-house team gives you continuity, a predictable number, and testers who remember your environment and can notice that last quarter’s fix regressed. The right choice depends on your volume, your budget model, and how much you value the same people returning. A useful test: count the assets you need tested in the next twelve months and the number of test windows. A handful of applications on a quarterly rhythm is a scheduling problem a fixed-price team solves well; hundreds of assets that change weekly is where a large bench or crowd earns its keep.
Frequently asked questions
What are PTaaS companies? Firms that deliver penetration testing as an ongoing program on a platform rather than a one-off project, with live findings, retesting and coverage that tracks your releases. They range from crowd-sourced platforms to in-house teams that include a platform with the service.
Which PTaaS companies use in-house testers? Of the firms on this list, Invadel, NetSPI, BreachLock and Software Secured state on their own pages that their testers are in-house. Cobalt, Synack, HackerOne and Bugcrowd describe vetted communities or freelance pools matched to each engagement, and Fluid Attacks’ PTaaS page does not say. It changes how well the tester knows your environment from window to window, so confirm it in writing.
Does PTaaS satisfy SOC 2 or PCI DSS? Usually, if the program produces the artifacts an auditor accepts: a defined scope, a methodology, a point-in-time report for the period, and evidence of remediation. A dashboard alone is not a report, so confirm the export before signing. See our compliance pages.
How is Invadel’s PTaaS different? Senior in-house testers do the work, the same people each window, the platform is included at no extra cost, retesting is included, and the program is one fixed price built from published fixed-scope tests, with no credits or seats.
The short version
Shortlist two or three PTaaS companies whose model fits your volume and budget. Ask each the same questions: who tests, are they employees, how do you pay, is retesting really included, and what the contract commits a human tester to do. Then put their sample reports next to each other and read the findings, not the cover page. If a fixed-price program with senior in-house testers and a free retest fits, scope your program and get the number in writing.
