Serious testing, delivered like a good experience.
We started Plainsight Security because security testing didn't have to be slow, jargon-heavy or full of nasty surprises. Senior skills, run the way you'd actually want to be treated.
Senior testing, start to finish.
Your engagement is led end to end by an experienced senior tester. There's no hand-off to a junior, and no re-explaining your environment to someone new halfway through.
We scope carefully, price it once, and report in language your board and your engineers can both act on. When the fixes are done, we re-test them; that's included. That's what we mean by frictionless: the security gets harder, the experience gets easier.
Three commitments
- No surprises. Fixed price, written scope, dates that suit you.
- Plain English. Reports a non-specialist can follow, with the technical depth your team needs underneath.
- Done means fixed. Aftercare and remediation re-tests come as standard.
How we keep the bar high.
Infrastructure testing follows a recognised methodology; web application testing follows the OWASP standards. The point isn't the badges: it's that the work is done thoroughly, by hand, and reported so you can act on it.
Our lead tester holds The Cyber Scheme's Team Leader qualification for infrastructure testing, one of the certifications recognised by the NCSC against UK government standards, which applies to the external and internal infrastructure work we deliver.
They are also a UK Cyber Security Council registered Principal Cyber Security Professional (PriCSP) in Security Testing, the Council's chartered-level professional standard for the field.
And we practise what we preach: Plainsight Security is itself Cyber Essentials Plus and IASME Cyber Assurance certified. Whatever the engagement, you get senior, hands-on testing and a report written to be used, not filed away.
