Two terms that are often confused \u2014 but are fundamentally different things. Understanding the difference helps you make better decisions for your IT security.<\/p>\n
A vulnerability scan is an automated assessment of your systems for known weaknesses. The software connects to your servers, identifies installed services and software versions, and compares them against databases of known vulnerabilities (CVEs).<\/p>\n
Characteristics:<\/strong><\/p>\n A penetration test (pentest) is a manual assessment carried out by a security specialist. The tester attempts to break into your systems like a real attacker \u2014 with creativity, experience and tools that go beyond automated scans.<\/p>\n Characteristics:<\/strong><\/p>\n A vulnerability scan finds known problems quickly and broadly. A pentest also finds unknown problems, but in a targeted and expensive way.<\/p>\n An example: the vulnerability scan detects that your Exchange server has a known CVE and no patch is installed. A pentester would additionally check whether the internal mail forwarding is configured in a way that allows an attacker to use this CVE to access management emails.<\/p>\n Both have their place. But the order matters.<\/p>\n Many companies commission a penetration test before they have ever run a vulnerability scan. That is like hiring an interior designer to renovate your flat while the roof is still leaking.<\/p>\n The recommended order:<\/strong><\/p>\n The scan ensures basic hygiene. The pentest provides depth. Without basic hygiene, the pentest is wasted money \u2014 half the findings would be things an automated scan would have caught too.<\/p>\n\n
