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.
One senior tester, start to finish.
Your engagement is led end to end by a Cyber Scheme Team Leader (CSTL) qualified 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 — 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.
What CSTL means for you.
CSTL — Cyber Scheme Team Leader — is a senior, hands-on penetration testing certification from The Cyber Scheme.
The Cyber Scheme is one of the bodies whose exams are recognised by the NCSC against UK government standards for penetration testing. Our lead tester holds the CSTL in its infrastructure specialism (CSTL-INF), which covers both the external and internal infrastructure testing we deliver.
In short: the person testing your systems has proven, at an assessed senior level, that they can do it properly.
