Our Experience Is Your Advantage

Hear what our incredible customers have to say!

Pentesys has continuously performed admirably during our collaboration, giving us faith in their knowledge. They delivered work that above our expectations by approaching each project with a deep understanding of our specifications. Their team demonstrated a remarkable degree of proficiency by effectively pinpointing weaknesses and offering practical suggestions to reduce possible hazards.

Fortis Cyber Security Limited
MD

Pentesys has continuously produced excellent work. Their group demonstrated extraordinary technical proficiency by spotting crucial flaws and offering clever fixes that greatly strengthened our security stance. Their meticulous approach and attention to detail ensured that every facet of the project was covered in full.

Rightmove PLC
IT Security Specialist

Unlike previous pentests that produced generic outputs, this engagement gave us clear, prioritised actions with real-world attack scenarios. The platform visibility into assets, vulnerabilities and remediation progress has helped us mature our security posture significantly. The team were professional, responsive, and genuinely cared about improving our security rather than just ticking a box.

Healthcare Technology Company
Head of IT

We engaged Pentesys and the team for a complex penetration test and adversary simulation. The quality of the technical findings, realism of the attack paths, and clarity of reporting were outstanding. The recommendations were practical and mapped clearly to business risk, which made board-level conversations much easier. We’ve since built Mirage into our ongoing security assurance programme.

UK Financial Services Provider
CTO

The red team and external attack surface management work highlighted blind spots we didn’t know existed. What stood out was the strategic guidance alongside the technical delivery – helping us shape a longer-term security roadmap rather than a one-off engagement. This felt like a partnership, not just a transactional assessment.
