Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

Has helped with regional threat monitoring but needs better documentation and real-time capabilities
The documentation from Microsoft needs significant improvement. The documents are disorganized, with one document linking to another, making the steps unclear and difficult to follow. Regarding updates, it is not truly real-time as it takes between eight to twelve hours for updates to occur. It would be beneficial if updates could happen more quickly, perhaps within 10 minutes to half an hour. Support for integration and documentation needs to be more straightforward. The pricing is expensive, even though it is part of the E5 package.
reviewer2805510 - PeerSpot reviewer
Partner Account Manager at a wholesaler/distributor with 51-200 employees
Proactive exploit intelligence has transformed how we prioritize real-world vulnerability risks
VulnCheck needs improvement in terms of data. It is primarily an intelligence and data layering system and not a complete vulnerability management platform. This means that it lacks native patch workflows, so you do not have asset discovery as you would with Tenable or Qualys. You will require other tools to act on the data that you find, which necessitates engineering time for API integration, data mapping, and tuning. Additionally, not all exploit signs are clear; some can be noisy or ambiguous, so teams need to apply their judgment. Finally, the time to value is not instant; it requires integration, workflow changes, and team training. I think VulnCheck is an excellent tool and valuable data resource. However, if you wish to send alerts via an API to platforms like Rapid7 or Tenable VM, you will need to integrate that with a SIEM solution to perform any kind of risk management.
