How many false positives does the scanner report?False positives are when a vulnerability scanner detects a vulnerability that isn’t one. This usually happens with a bug that’s been patched up. When selecting a scanner, you’ll need to consider false positives. The more false positives, the more time you spend sifting through issues. An ideal scanner has few false positives.
How often does the scanner update?The frequency of updates changes with each scanner. Some update monthly, weekly, or even daily. Since attackers are constantly changing tactics, you should find a scanner that updates frequently to combat these attacks.
Remember, when choosing your vulnerability scanner, you must decide what works best for your business. Consider you company’s unique needs and find the best scanner to keep your business secure.
