Network vulnerability scanning is the process of identifying weaknesses on a computer, network, or other IT asset that are potential targets for exploitation by threat actors. Scanning your environment for vulnerabilities informs you of your current risk posture, the effectiveness of your security measures, and opportunities to improve your defenses through vulnerability remediation.
Obtaining and deploying a network vulnerability scanner is often the first step in creating a more proactive security program. To face modern attackers, it’s no longer enough to build high walls and wait out a siege; modern security programs have to identify the holes that they could exploit and seal them up before threat actors can take advantage. Network vulnerability scanners let you quickly assess your network for these holes, show you how to prioritize and remediate flaws, and provide a great barometer for the overall success and progress of your security team.

Network vulnerability scanners should be built to scan the entirety of your IT infrastructure and identify potential weaknesses that can be exploited. To do so, a scanner should have (at minimum) the following capabilities:
The scan coverage of a network vulnerability scanner is crucial, since you don’t want to miss any vulnerabilities left open to attack due to blind spots. This extends to a scanner’s responsiveness to and coverage of zero-day vulnerabilities. Keep this in mind while engaging vendors in the proof-of-concept (POC) process, which brings us to our next point...
Every company’s network is different; it’s important to implement a vulnerability scanner that can intelligently scan everything from PCI environments to hospitals with minimal configuration and manual adjustment. This also means that your network vulnerability scanner has to be extremely accurate, with a robust set of vulnerability checks against every major flavor of software and operating system (OS). At times, this also extends to more esoteric systems like SCADA controls.
Most commercial network vulnerability scanners do a good job of keeping up with the latest vulnerability checks; often, what makes or breaks a successful program is what comes next. Prioritizing thousands of vulnerabilities across different types of devices and different segments of your network is critical to ensuring that your team is as efficient as possible. Why? You’ll never have the luxury of fixing every single vulnerability you find. Once that’s done, you have to get the information to the right people; it’s critical that your network vulnerability scanner has the ability to easily show remediation steps to the people responsible for remediation, as well as show management how you’re improving your company’s security over time with executive level reporting.
