A scalable tool that needs to make its setup phase easier while improving the stability it provides
The initial setup of Tenable.io Container Security is a little bit complex. If you have a bigger cluster or container environment, then the solution's deployment phase may take more than three months since you won't directly go for the solution's block mode. To start things in the solution, you will have to deploy it in SIEM mode, while the detection mode will provide you with visibility in accordance with which you need to take actions for production, which needs time. Regarding the time taken for deployment, for detection, it may not take more than a week, but in production, it may take at least three months to be completed. For the deployment process, there are some scripts available along with some YAML files that you need to run on the cluster, specifically considering the cluster you want to focus more on before creating Tenable Cloud Security Console. After creating Tenable Cloud Security Console, you can proceed with the onboarding process.

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 strong security provided by the product in the container environment is its most valuable feature."
"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."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"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."
"Nessus scanner is very effective for internal penetration testing."
"Every other security tool we've looked is good at containers, or at Kubernetes, is good at AWS, or at instance monitoring. But nobody is good at tying all of those things together, and that's really where Threat Stack shines."
"Threat Stack has connectivity."
"An important feature of this solution is monitoring. Specifically, container monitoring."
"It has been quite helpful to have the daily alerts coming to my email, as well as the Sev 1 Alerts... We just went through a SOX audit and those were pivotal."
"There has been a measurable decrease in the meantime to remediation... because we have so many different tech verticals already collated in one place, our ability to respond is drastically different than it used to be."
"Technical support is very helpful."
"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 like the ability of the host security module to monitor the processes running on our servers to help us monitor activity."
 

Cons

"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 stability and setup phase of the product are areas with shortcomings where improvements are needed."
"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."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The initial setup is highly complex."
"The solution’s pricing could be improved."
"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."
"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."
"It shoots back a lot of alerts."
"Some features do not work as expected."
"The solution’s ability to consume alerts and data in third-party tools (via APIs and export into S3 buckets) is moderate. They have some work to do in that area... The API does not mimic the features of the UI as far as reporting and pulling data out go. There's a big discrepancy there."
"I would like further support of Windows endpoint agents or the introduction of support for Windows endpoint agents."
"The compliance and governance need improvement."
"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 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."
 

Pricing and Cost Advice

"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."
"The product does not operate on a pay-per-license model."
"I rate the product’s pricing a six out of ten."
"The solution's pricing is neither cheap nor very expensive."
"I rate the tool's pricing a three out of ten."
"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."
"Pricing seems to be in line with the market structure. It's fine."
"It came in cheaper than Trend Micro when we purchased it a few years ago."
"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."
"It is a cost-effective choice versus other solutions on the market."
