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.

Cloud security has cut investigation time and now reveals threats faster but needs simpler oversight
When deploying AI applications, my key security concerns with Microsoft Defender for Cloud are data loss, leakage of data, and guardrails around the actual AI, and I am hoping that this is going to help me put those guardrails in place and identify data exfiltration. Microsoft Defender for Cloud has not helped me manage and secure multi-cloud environments, as we are 100 percent Microsoft and have not really got it in any other environment at all. I am not yet using the unified AI-powered security feature offered by Microsoft Defender for Cloud, but that is coming. I am not yet using the integrated XDR feature of Microsoft Defender for Cloud, but that is coming. I am not yet utilizing the GenAI threat protection features of Microsoft Defender for Cloud. That is also coming and a lot of that will come from learning it here. I have enabled the agentless scanning in my cloud environment with Microsoft Defender for Cloud. Assessing the impact on my workload protection without needing to install agents with Microsoft Defender for Cloud makes it a lot easier, but it also identifies a lot more, which puts more load on me sometimes. I would advise another organization considering Microsoft Defender for Cloud that it is the most logical route to follow if their whole ecosystem is Microsoft. It is easy to implement and it is very self-explanatory when doing it, making sense to just follow the steps as it is too simple, really. I would rate this review a 7.5 out of 10.

SecOps program for us, as a smaller company, is amazing; they know what to look for
They could give a few more insights into security groups and recommendations on how to be more effective. That's getting more into the AWS environment, specifically. I'm not sure if that's Threat Stack's plan or not, but I would like them to help us be efficient about how we're setting up security groups. They could recommend separation of VPCs and the like - really dig into our architecture. I haven't seen a whole lot of that and I think that's something that, right off the bat, could have made us smarter. Even as part of the SecOps Program, that could be helpful; a quick analysis. They're analyzing our whole infrastructure and saying, "You have one VPC and that doesn't make a lot of sense, that should be multiple VPCs and here's why." The architecture of the servers in whatever cloud-hosting provider you're on could be helpful. Other than that, they should continue to expand on their notifications and on what's a vulnerability. They do a great job of that and we want them to continue to do that. It would be cool, since the agent is already deployed and they know about the server, they know the IP address, and they know what vulnerability is there, for them to test the vulnerability and see if they can actually exploit it. Or, once we patch it, they could double-check that it can't be. I don't know how hard that would be to build. Thinking on it off the top off my head, it could be a little challenging but it could also be highly interesting. It would also be great if we could test a couple of other features like hammering a server with 100 login attempts and see what happens. Real test scenarios could be really helpful. That is probably more something close to what they do with the SOC 2 audit or the report. But more visualization of that, being able to test things out on our infrastructure to make sure we can or can't hit this box could be interesting.
