Professional penetration testing services for UK businesses. We simulate real-world attacks against your network, applications, and infrastructure – then give you a clear, prioritised report showing exactly what to fix and how. CISSP-certified pen testing expertise. No jargon. No 200-page documents nobody reads.
We’ll review your network and show you where you’re exposed.




Antivirus is installed. The firewall is on. MFA is enabled. But have you actually verified that an attacker couldn't get in? Assumption isn't assurance.
More cyber insurance policies and supply chain assessments now require evidence of regular penetration testing. A checkbox on a self-assessment form isn't enough.
Automated vulnerability scans are a starting point, not a destination. They tell you what might be wrong. A penetration test tells you what an attacker can actually exploit.
The average cost of a cyber attack for a UK business is £8,460 (DCMS 2024). For businesses that handle client data, the reputational cost is often far higher.
We test your internet-facing infrastructure – firewalls, VPNs, web servers, email gateways – looking for misconfigurations, unpatched vulnerabilities, and weaknesses that an external attacker could exploit.
For businesses with customer-facing web applications, we test for common vulnerabilities including injection attacks, authentication flaws, and data exposure risks – aligned with the OWASP Top 10.

Simulating an attacker who has gained initial access (or a malicious insider), we test what they could reach, escalate, and exfiltrate from inside your network.

For businesses with customer-facing web applications, we test for common vulnerabilities including injection attacks, authentication flaws, and data exposure risks – aligned with the OWASP Top 10.

We test your team's susceptibility to social engineering. How many of your employees would click a realistic phishing email? The answer is almost always higher than you'd expect.

We assess your Wi-Fi infrastructure for rogue access points, weak encryption, and misconfiguration that could allow an attacker onto your corporate network.
We define the scope, objectives, and rules of engagement. You decide what to test and we agree boundaries – so there are no surprises.
