Here's some options: 1. Tenable.io: I'm currently using this one. One issue I have is it holds onto old data from decommissioned servers for 90 days that's used to generate the risk score displayed in Lumin. So it would be better to have an option to report on real-time data. 2. Kenna Security: I used this one for a while and it was ok but it had syncing issues/delays sometimes that made the remediation process frustrating because it was reporting issues that had already been fixed and it took too long for the results to show in Kenna. 3. Vulcan.io: I'm currently evaluating this product. So far it's ok but new and has bugs in it.
