Full-scope penetration testing across external and internal, network, web and API, wireless and wired, and OT / critical infrastructure, plus OSINT and phishing simulation, delivered by certified and qualified testers.

Vulnerability Assessment and Penetration Testing finds the weaknesses an attacker would exploit and proves which ones are genuinely reachable, so you fix what matters before someone else finds it. Threats and your own systems change constantly, so testing is an ongoing discipline, not a one-off tick-box.
We test across seven areas, from your external perimeter and internal network to web applications, APIs, wireless, wired and OT environments, alongside OSINT and phishing simulation. Every engagement is safe, authorised and tightly scoped, run by certified professionals, and reported in clear business terms leaders and engineers can both act on.
Seven areas of offensive testing - from your perimeter to OT, plus the human and public-exposure layers.
Tests your perimeter and what an attacker could reach once inside.
Assesses the servers, services and devices that run your network.
Tests web apps, services and APIs against real exploitation.
Probes Wi-Fi and physical network access for weaknesses.
Safe, non-disruptive testing for live control environments - we assess without risking uptime or safety.
Maps what attackers can learn about you from public sources.
Measures how your people respond to realistic attacks.
A structured method that mirrors a real attacker, safely.
We test the way real adversaries operate, aligned to recognised standards including PTES, OWASP, NIST SP 800-115, OSSTMM and MITRE ATT&CK. Every engagement is safe, authorised and tightly scoped, with clear rules of engagement agreed up front - so you gain genuine attacker insight without risk to live operations.
