PENETRATION TESTING MANCHESTER
A penetration test is 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.
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 provide clear reporting, prioritised findings, and remediation support to help you strengthen your security posture.
Uncover vulnerabilities such as injection flaws and authentication weaknesses in your web applications.
Assess corporate networks, perimeter systems, and endpoints through internal and external testing.

SATISFIED CLIENTS
We take pride in our work and our clients are our biggest advocates. Here's what they have to say about us.
My international media training company needed Cyber Essentials and Cyber Essentials Plus for our work with a UK Government department. David guided us through the whole process with professionalism and with charm. We've worked with other consultants in this area before, but compared to David that was an off the shelf response.
David gives a much more personal service and was also more cost effective for us. I've already recommended him in real life to another business owner I work with and would like to do the same here.
I know a moderate amount about Cyber Security but I have a fellow Director for whom this field is a total mystery. David was able to flex his approach to work well with both of us and is very good at picking up whether what he's said has been fully understood. These communication skills, alongside a solid understanding of his field, set him apart from others in this sector and I will definitely be engaging his services again in future.
