Pentest vs vulnerability assessment — which do you need?

"Pentest" and "vulnerability assessment" are used interchangeably far too often. They are different tools for different jobs.

Vulnerability assessment: breadth and frequency

A vulnerability assessment scans widely and regularly to find known weaknesses across your estate. It is automated, repeatable and ideal for continuous coverage and compliance evidence. The trade-off: it finds potential issues, not proven impact.

Penetration testing: depth and proof

A penetration test is a manual, expert-led engagement that exploits and chains weaknesses to prove real impact — how far an attacker could actually get. It finds the business-logic and authorization flaws scanners miss.

So which do you need?

Most organizations need both, at different cadences:

  • Run a vulnerability assessment monthly or quarterly for broad, ongoing visibility.
  • Run a penetration test at least annually, and after any major change.
