About Pentestly

    More attack-surface coverage. No blurred accountability.

    Pentestly is a UK penetration testing company built around a simple operating idea: give skilled in-house testers better leverage with AI, then keep a human visibly responsible for every result delivered to the client.

    Why we exist

    Pentesting should be easier to buy, follow and act on

    Traditional engagements often disappear between a kickoff call and a final PDF. Automated products create the opposite problem: constant output without enough judgement. Pentestly connects the useful parts of both models.

    AI agents help our testers explore more hypotheses and handle repetitive analysis. The tester remains responsible for business-logic testing, safe exploitation, severity, evidence and the conversation with your engineers. The delivery portal keeps the scope, project activity, findings, comments, reports and retests together.

    The result is not “AI instead of a pentester” or “manual because that is how it has always been done.” It is a modern testing workflow designed to increase useful signal.

    Delivery principles

    What clients should be able to hold us to

    One accountable owner

    A named tester owns the technical judgement and stays reachable through delivery, debrief and remediation retest.

    AI with explicit boundaries

    Bespoke agents expand exploration and assist analysis. They do not publish findings, assign business risk or replace human validation.

    Evidence engineers can use

    Every finding is written to reproduce, understand and fix—not to maximise page count or make routine scanner output look impressive.

    Closure is part of delivery

    The engagement continues through questions, remediation and retesting so your final evidence reflects what was actually resolved.

    Practitioner-led research

    Pentestly Labs documents techniques, methodologies and remediation lessons from offensive-security work. Articles identify their author and publication date so readers can judge the context rather than rely on anonymous marketing copy.
