Improves organizational security with features like scanning, reporting, and troubleshooting
Tenable.io Container Security has improved our security.  The tool's most valuable feature is scanning, reporting, and troubleshooting.  Tenable.io Container Security should improve integration modules. It should also improve stability.  I have been working with the product for two years.  I…

Pivotal for SOX and Sarbanes-Oxley compliance as well as security in AWS, but needs work on the application layer side
It certainly has a lot of capabilities and we're not using much of what it can do. That's something that, as we mature as an organization, we'll expand into. The one thing that we know they're working on, but we don't have through the tool, is the application layer. As we move to a serverless environment, with AWS Fargate or direct Lambda, that's where Threat Stack does not have the capacity to provide feed. Those are areas that it's blind to now, so that's the biggest area for improvement. They're currently looking at changing that with an acquisition, but as it stands right now, that's the only spot that I consider weak.

Quotes from Members

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

Pros

"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"The strong security provided by the product in the container environment is its most valuable feature."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"It is a scalable solution. Scalability-wise, it is a good solution."
"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."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"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."
"Nessus scanner is very effective for internal penetration testing."
"Technical support is very helpful."
"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."
"We're using it on container to see when activity involving executables happens, and that's great."
"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."
"Threat Stack has connectivity."
"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."
 

Cons

"The support is tricky to reach, so we would like better-oriented technical support enabled."
"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 initial setup is highly complex."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The solution’s pricing could be improved."
"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."
"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."
"I would like further support of Windows endpoint agents or the introduction of support for Windows endpoint agents."
"The one thing that we know they're working on, but we don't have through the tool, is the application layer. As we move to a serverless environment, with AWS Fargate or direct Lambda, that's where Threat Stack does not have the capacity to provide feed. Those are areas that it's blind to now..."
"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."
"The compliance and governance need improvement."
"It shoots back a lot of alerts."
"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."
"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."
"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."
 

Pricing and Cost Advice

"I rate the tool's pricing a three out of ten."
"The solution's pricing is neither cheap nor very expensive."
"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."
"Pricing seems to be in line with the market structure. It's fine."
"It is very expensive compared to some other products. The pricing is definitely high."
"It came in cheaper than Trend Micro when we purchased it a few years ago."
"It is a cost-effective choice versus other solutions on the market."
"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."
"We find the licensing and pricing very easy to understand and a good value for the services provided."
"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."
