What Is Penetration Testing?
A penetration test is often the difference between finding a critical flaw yourself and reading about it in a breach notification letter. It also satisfies the growing list of frameworks, from PCI DSS 4.0 to Cyber Essentials Plus, that now require regular, evidenced testing rather than a simple scan.
Every test is run by hand by a senior consultant and written up in plain English, so your team knows what an attacker could reach and what to fix first. No filler, no scare tactics, just a clear picture and a short list of priorities.
