PenetrationTestingasaService
Continuous, CREST-aligned penetration testing delivered as a service — AI-accelerated coverage, human validation, live findings and retesting included.
Testing that keeps pace with your releases
Penetration Testing as a Service replaces the annual engagement with an ongoing programme: continuous testing, live findings and validated remediation, all in one portal.
Most organisations ship code weekly and test security annually. PTaaS closes that gap. Pentesys runs discovery, automated coverage and manual exploitation on a rolling schedule, so every meaningful change to your applications, APIs, cloud and perimeter is assessed while it still matters.
Everything is delivered through the Mirage Portal. Findings are published as they are confirmed, tracked to closure with free retesting, and rolled up into trend reporting that satisfies boards, auditors, insurers and enterprise customers.
Six things an annual pentest cannot give you
The PTaaS model changes how testing is delivered, consumed and evidenced.
Continuous, not annual
Testing runs on a rolling schedule that follows your release cadence, so new code and new infrastructure are assessed when they ship — not eleven months later.
Live findings, not a PDF
Every confirmed issue is published to the Mirage Portal as it is found, with CVSS v3.1 scoring, evidence, reproduction steps and remediation guidance.
Retesting included
Fix a finding, request a retest from the portal and get validated closure with an auditable trail — no change request, no extra invoice.
AI-accelerated, human-validated
Automation handles breadth and regression coverage; CREST-aligned consultants handle chaining, business logic and exploitation. Nothing reaches you unvalidated.
Credit-based commercials
Buy testing credits up front at £125 per credit and draw them down across the year against whatever needs testing next.
Integrated with your workflow
Findings flow into Jira, ServiceNow, Slack and your SIEM so remediation lives where your engineers already work.
PTaaS vs traditional penetration testing
The same rigour and the same accreditations — a very different delivery model.
| Area | Traditional pentest | Pentesys PTaaS |
|---|---|---|
| Testing frequency | Once a year | Continuous, aligned to releases |
| Findings delivery | PDF weeks later | Live in the portal as confirmed |
| Retesting | Chargeable extra | Included |
| Scope changes | New statement of work | Draw down credits |
| Coverage between tests | None | Continuous monitoring and regression testing |
| Reporting | Static document | Live dashboards, trends and board-ready exports |

“Our mission is continuous penetration testing — enabling businesses to evolve from static, point-in-time tests. Assurance is the key, not just testing.”
James Hinton · Founder
AI acceleration included in every service line
We embed AI-assisted automation across Pentesys services to speed up testing and make continuous security assurance more affordable — without sacrificing the human validation that makes findings trustworthy.
AI built into every service line
From attack surface discovery to vulnerability scanning and report drafting, AI acceleration is included in every engagement — not an add-on.
Faster testing cycles
Automated assessment runs continuously across your external surface, networks, applications and APIs, so coverage keeps pace with releases.
Human validation on every finding
Qualified consultants review, triage and confirm every AI-generated result before it reaches you, so you only act on real risk.
Security assurance made affordable
By automating repetitive reconnaissance and scanning work, we keep consultant time focused where it matters — giving you continuous assurance at a sustainable cost.
CREST Approved
Independently assessed against the highest technical and operational standards in the penetration testing industry.
CREST approved penetration testing
CREST accreditation means our people, processes and reporting have been independently validated — so you can trust the results and prove them to anyone who asks.
CREST-approved methodology
Every engagement follows CREST-aligned scoping, testing and reporting standards — repeatable, auditable and accepted by regulators, insurers and enterprise procurement teams.
Qualified, vetted consultants
Testing is delivered by certified consultants working to CREST codes of conduct and ethics, with background-checked personnel and strict handling of client data.
Evidence your stakeholders accept
CREST-aligned reports and attestation letters map findings to risk, so boards, auditors and customers get assurance in a format they already recognise.
PTaaS questions we get asked most
Straight answers on scope, cost, compliance and how continuous testing actually works.
What is PTaaS?
Penetration Testing as a Service (PTaaS) is a subscription-based delivery model for penetration testing. Instead of a single annual engagement and a PDF, testing runs continuously, findings are delivered live through a portal, and retesting is included so remediation can be validated as soon as fixes ship.
How is PTaaS different from traditional penetration testing?
Traditional penetration testing is point-in-time: it tells you what was true on the day of the test. PTaaS keeps testing as your environment changes, combines automated coverage with human exploitation, and gives you a live view of exposure rather than a static report.
Is PTaaS just automated scanning?
No. Automation provides breadth and regression coverage, but every finding is validated by a CREST-aligned consultant before it is published, and manual testing covers business logic, chained attack paths and authorisation flaws that scanners cannot reach.
How much does PTaaS cost?
Pentesys PTaaS starts from £1,850 per month, and testing credits are £125 per credit. Prices exclude UK VAT and can be paid upfront or spread over twelve months.
Does PTaaS satisfy compliance requirements?
Yes. Engagements are CREST-aligned and produce the formal, signed reports required for ISO 27001, SOC 2, PCI DSS and customer assurance, alongside the live portal view.
