Detailed container image reports have improved vulnerability insight and support secure operations
Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning. Tenable.io Container Security is giving me the vulnerability information of Docker images and the information about software bill of materials. However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate. That is the primary concern regarding the benefits of real-time visibility into my containerized application security status.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"The strong security provided by the product in the container environment is its most valuable feature."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"Currently, I haven't implemented the solution due to its deprecation by the site. However, I can highlight some benefits of Tenable Cloud Security, a cybersecurity solution with various features for scanning vulnerabilities in both cloud environments and on-premises container security."
"Tenable.io detects misconfiguration when you deploy a Docker or Kubernetes container. It's much better to remedy these issues during deployment instead of waiting until the container is already in the production environment."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"The strong security provided by the product in the container environment is its most valuable feature."
"It is a fantastic tool that gives us a level of comfort knowing that there is not only something that's watching, something that can alert and detect, but also knowing that there's an outsourced operation center that can be an auxiliary part of our security team."
"The SecOps program is absolutely amazing when you do not have a dedicated resource for security."
"With Threat Stack, we quickly identified some AWS accounts which had services that would potentially be exposed and were able to remediate them prior to release of products."
"The number-one feature is the monitoring of interactive sessions on our Linux machines. We run an immutable environment, so that nothing is allowed to be changed in production... We're constantly monitoring to make sure that no one is violating that. Threat Stack is what allows us to do that."
"An important feature of this solution is monitoring. Specifically, container monitoring."
"The rules are really great. They give us more visibility and control over what's being triggered. There's a large set of rules that come out-of-the-box. We can customize them and we can create our own rules based on the traffic patterns that we see."
"We're using it on container to see when activity involving executables happens, and that's great."
"The most valuable feature is the SecOps because they have our back and they help us with the reports... It's like having an extension of your team. And then, it grows with you."
 

Cons

"The initial setup is highly complex."
"The initial setup is highly complex."
"I believe integration plays a crucial role for Tenable, particularly in terms of connecting with other products and various container solutions like Docker or Kubernetes. It seems that in future updates, enhanced integration is something I would appreciate. Currently, there is integration with Docker, but when it comes to Kubernetes or other container solutions, it appears to be a challenge, especially with on-prem scanners."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The solution’s pricing could be improved."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"I feel that in certain areas this product has false positives which the company should work on. They should also try to include business logic vulnerabilities in the scanner testing. Finally, the vulnerability assessment feature should be increased to other hardware devices, apart from firewalls."
"They need to work on auto-remediation so it's easier for the security team to act quickly when certain assets or resources are deployed. The latest version has a CIS benchmark that you need to meet for containers in the cloud, but more automation is needed."
"The user interface can be a little bit clunky at times... There's a lot of information that needs to be waded through, and the UI just isn't great."
"The reports aren't very good. We've automated the report generation via the API and replaced almost all the reports that they generate for us using API calls instead."
"The compliance and governance need improvement."
"The compliance and governance need improvement."
"The API - which has grown quite a bit, so we're still learning it and I can't say whether it still needs improvement - was an area that had been needing it."
"Some features do not work as expected."
"I would like further support of Windows endpoint agents or the introduction of support for Windows endpoint agents."
"It shoots back a lot of alerts."
 

Pricing and Cost Advice

"I rate the product’s pricing a six out of ten."
"The product does not operate on a pay-per-license model."
"It's best to be an institutional buyer and directly contact the sales team as they can provide over-the-top discounts for bulk orders."
"I rate the tool's pricing a three out of ten."
"The solution's pricing is neither cheap nor very expensive."
"I'm happy with the amount that we spend for the product that we get and the overall service that we get. It's not cheap, but I'm still happy with the spend."
"We find the licensing and pricing very easy to understand and a good value for the services provided."
"It is very expensive compared to some other products. The pricing is definitely high."
"What we're paying now is somewhere around $15 to $20 per agent per month, if I recall correctly. The other cost we have is SecOps."
"It came in cheaper than Trend Micro when we purchased it a few years ago."
"Pricing seems to be in line with the market structure. It's fine."
"It is a cost-effective choice versus other solutions on the market."
