Important Features To Consider When Choosing A Vulnerability Scanning Service

Vulnerability scanners are helpful tools that can check your system for any loopholes or weaknesses. This type of software is beneficial because it automatically provides users with suggestions for fixes and progress tracking.

  1. The scanner should be able to integrate into your CI/CD pipeline

By having a web application vulnerability scanner as part of your CI/CD, you can automatically scan for vulnerabilities every time there is new code to deploy. This works along with the usually automated scans that occur on a schedule. It's essential because it helps prevent possible security breaches and weaknesses from occurring in the first place.

  • Deploy security controls
  • Update their statuses
  • Have a discussion with security experts about the concerns  
  1. The vulnerability reports should be useful and provide a clear plan of action

A vulnerability scanning report is only useful if it's easily understood and practical. A threat scanner that offers risk scores and video footage of the vulnerabilities will be much more useful to you in the long run.

  1. Making compliance easier is one of the key benefits of using a vulnerability scanner

Nobody looks forward to a compliance audit, but you can make the experience less painful by using a vulnerability scanning tool that runs compliance-specific scans. This way, you can fix any issues before the auditor's arrival.
