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.

Cloud-based platform simplifies device and data center management
I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.
