# Pluto Cyber Security > Manual-first penetration testing and cybersecurity for UK businesses. Engagements are scoped and authorised in writing, run by senior certified engineers, and closed out with audit-ready reporting and a free retest. Pluto Cyber Security is a UK cybersecurity firm specialising in manual, engineer-led penetration testing. Every engagement is run by senior, certified operators (OSCP, CISSP, CISM, CEH and more), scoped up front at a fixed price, and closed out with a free retest once fixes ship.
