Penetration Testing Services
Find weaknesses before attackers do
Whether you're meeting a requirement or taking a proactive step to strengthen security — you're in the right place. Many organisations arrange penetration tests because it's required by a framework, tender, or policy. Others choose to test proactively as part of a mature approach to managing cyber risk. Whichever position you're in, we make the process straightforward, credible, and proportionate to your needs.
What is a penetration test?
A hands-on security assessment of your technology — such as your network, website, or cloud platform — designed to identify vulnerabilities that malicious actors could exploit.
We simulate realistic attack scenarios to show how an adversary might gain access, then provide clear, actionable guidance so you can fix issues before they're exploited.
Why get one?
- • Required for tenders, frameworks, or customer assurance.
- • Demonstrates proactive security to clients and insurers.
- • Helps prevent cyber attacks by finding issues early.
- • Supports compliance with ISO 27001, Cyber Essentials Plus, and DCC.
