What is PTaaS?
Penetration testing as a service, not a one-off engagement
Penetration Testing as a Service (PTaaS), sometimes called continuous security testing, delivers ongoing manual penetration testing through a fixed monthly retainer. Your attack surface is assessed as your product, infrastructure and team change, rather than once a year.
An organisation shipping features weekly can introduce new endpoints, infrastructure changes and regressions between annual tests that no one has looked at. With PTaaS, testing keeps pace with those changes, and you have a continuous record of testing for compliance.
Engagements start from £5,700 per month and are delivered by UK-based consultants working directly with you throughout.
Included every month
- Continuous security testing
- See findings as they're discovered
- Regular full or interim pentest reports
- Fixed monthly subscription costs
Why penetration test as a service?
An annual test tells you how secure you were on a single day. If you ship every week, the rest of the year runs on assumptions. Continuous testing gives you ongoing assurance that your security is keeping pace with your change.
Is PTaaS Right for You?
When to choose continuous testing over a point-in-time pentest
A one-off penetration test makes sense for a specific moment, such as a compliance deadline, a product launch or a board requirement. Consider PTaaS if any of the following apply to your organisation.
Your product ships continuously
If your development team releases weekly or fortnightly, a point-in-time test goes stale quickly. PTaaS means testing keeps pace with your release cycle rather than falling behind it.You need predictable security spend
One-off tests vary in cost depending on scope and timing. A fixed monthly PTaaS subscription lets you plan security expenditure without unexpected quotes each time you need testing.You want a security partner, not a supplier
Your consultant builds familiarity with your environment, architecture and risk profile over time, which produces better findings than a tester seeing it for the first time.You're preparing for or maintaining a certification
ISO 27001 and SOC 2 don't mandate penetration testing by name, but auditors commonly ask for testing evidence. PTaaS produces a continuous, dated record of testing activity you can show them at any point in the year.You're a DevSecOps team that needs security integrated into delivery
We can work directly with your development teams to implement security testing into your CI/CD pipeline, sprint cycles, and release processes as an extension of your team.
How PTaaS Works
How Exploitr's PTaaS is delivered
PTaaS provides consistent testing capacity that fits your organisation's delivery rhythm.
01
Scope Once
We work with you to define assets, environments, and rules of engagement upfront. You approve the scope and we operate within it for the duration of the subscription, so there are no repeat scoping calls or new contracts each time testing starts.
If your environment changes significantly, scope can be adjusted by agreement.
02
Continuous or Scheduled Delivery
Direct and schedule testing yourself, or allow our consultants to independently pursue the highest-risk attack paths within your approved scope.
We can align with your sprint or release cadence, test ahead of key deployments, or run on a continuous rolling basis between changes. The approach is agreed at the start and can be adjusted as your delivery rhythm evolves.
03
Immediate Finding Visibility
Findings are delivered as testing happens via the Exploitr platform, not weeks later in a static PDF.
You see vulnerabilities as they are discovered, with severity ratings, reproduction steps, and remediation guidance available immediately. Your development team can begin remediation while testing is still in progress.
04
Track Remediation & Retest
Use our platform to track the status of every finding from discovery through to remediation. Fix an issue and request a retest directly within the platform, without starting a new engagement or re-scoping the work.
Retesting is included within your monthly subscription, so there are no additional charges to verify that a vulnerability has been resolved.
05
Ongoing Consultant Access
Your assigned consultant is your direct point of contact for the duration of the subscription, not an account manager or a rotating team. Questions about findings, remediation approaches and upcoming changes go directly to the consultant who has been testing your environment.

Common Questions
Penetration testing as a service: frequently asked questions
A testing day represents up to 8 hours of active manual penetration testing and reporting performed by an experienced tester.
Testing time includes:
manual testing and exploitation
analysis and validation of findings
writing findings and remediation guidance
and coordination with the customer.
It does not include sales or account management overhead.
PTaaS starts from £5,700 per month for 5 testing days, or from £11,100 per month for 10 testing days. Pricing is based on the volume of testing time you contract each month, so it scales with how much of your environment needs regular testing.
Plans run on a minimum 6-month term. If you commit to 12 months, we apply a further discount, which we confirm in your written quote.
Our penetration testing pricing guide compares costs across every service.
Yes. All plans are all-inclusive. There are no additional charges for reporting, retesting, or reasonable clarification sessions.
PTaaS can be used to cover most of our testing services, including web application pentesting, external penetration testing, internal network penetration testing, and API pentesting.
Unused days expire at the end of each month. Capacity is reserved exclusively for you, ensuring availability when you need it.
Yes. Scope can be adjusted by agreement and you can upgrade your plan at any time. We require written authorisation for testing but will make this as easy as possible as part of our ongoing service.
We work best when considered an extension of your team.
A common pattern is a pre-engagement meeting before a staging or production release, then testing begins when the environment is ready. We adapt to your sprint cadence, not the other way around.
A standard penetration test is a one-off engagement with a fixed scope and a single report. PTaaS replaces that with a monthly retainer providing:
ongoing testing capacity
continuous finding visibility through our platform
a consultant who builds familiarity with your environment over time.
The cost is predictable, coverage is continuous, and retesting is included.
PTaaS produces a continuous record of security testing activity throughout the year: dated test records, findings with severity ratings and remediation guidance, and retest confirmations as issues are resolved.
Neither ISO 27001 nor SOC 2 mandates penetration testing by name, but auditors commonly ask for testing evidence, and a twelve-month PTaaS testing log is straightforward to present to an auditor or assessor.
We can provide findings exports and reporting in formats suited to your audit requirements on request.
