Why pen testing once a year is no longer enough

Annual penetration tests are a start, but the threat landscape moves faster than that. Continuous vulnerability management is the new standard for serious UK businesses.

The problem with annual pen testing

Traditional penetration testing is conducted once a year, producing a snapshot of your security posture at a single point in time. But new vulnerabilities are discovered every day. A system that passed its pen test in January could be exposed by a critical CVE in March. Annual testing simply cannot keep pace.

What continuous vulnerability management looks like

Continuous vulnerability management replaces periodic snapshots with ongoing automated scanning, prioritisation, and remediation workflows. Your attack surface is monitored constantly, new vulnerabilities are flagged as soon as they are discovered, and your team receives prioritised remediation guidance based on actual risk rather than theoretical severity scores.

Why UK SMEs are particularly at risk

SMEs are disproportionately targeted precisely because attackers know they are less likely to have continuous monitoring in place. A single unpatched vulnerability in a web application or VPN can be the entry point for a ransomware attack that shuts down operations entirely.

How Hubfort approaches vulnerability management

Hubfort's vulnerability management service combines automated scanning with expert analysis. We identify, prioritise, and track vulnerabilities across your entire estate — from network infrastructure to web applications — and provide clear remediation guidance with defined SLAs. Annual pen testing remains a valuable compliance exercise, but it works best as part of a broader continuous programme.
