Andrew W - PeerSpot reviewer
Tells us about vulnerabilities as well as their impact and helps to focus on real issues
Looking at all the different pieces, it has got everything we need. Some of the pieces we do not even use. For example, we do not have Kubernetes Security. We are not running any K8 clusters, so it is good for us. Overall, we find the solution to be fantastic. There can be additional education components. This may not be truly fair to them because of what the product is going for, but it would be great to see additional education for compliance. It is not a criticism of the tool per se, but anything to help non-development resources understand some of the complexities of the cloud is always appreciated. Any additional educational resources are always helpful for security teams, especially those without a development background.

An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.
Yusuf-Hashmi - PeerSpot reviewer
It helps you catch misconfigurations before they go into a production environment where they're harder to deal with
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. Asset visibility is also critical. While Tenable provides visibility into containers, it could be done much better. Compliance is one of the most crucial aspects of container security. It should be more customizable. For example, I would like a rating system where Tenable reports a risk score for each container based on user-defined metrics, such as severity, activity, or compliance.

Quotes from Members

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

Pros

"I rate SentinelOne Singularity Cloud Security ten out of ten."
"SentinelOne Singularity Cloud Security offers three key features: vulnerability management notifications, cloud configuration assistance, and security scanning."
"Visibility is the most important aspect."
"It is scalable, stable, and can detect any threat on a machine. It uses artificial intelligence and can lock down any virus."
"The UI is responsive and user-friendly."
"The most valuable features of SentinelOne Singularity Cloud Security are the asset inventory and issue indexing."
"My favorite feature is Storyline."
"SentinelOne Singularity Cloud Security's integration is smooth. They are highly customer-oriented, and the integration went well for us."
"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."
"CoreOS Clair's best feature is detection accuracy."
"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."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"Nessus scanner is very effective for internal penetration testing."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"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."
"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."
 

Cons

"A few YouTube videos could be helpful. There isn't a lot of information out there to look at."
"The price is on the higher side. The dashboard can be more detailed."
"If something happens in our infrastructure, the alert appears on the dashboard, but I have to log in to the dashboard and refresh it. I would prefer it to provide better alerting and notifications so that I can resolve issues on priority."
"While SentinelOne offers robust security features, its higher cost may present a challenge for budget-conscious organizations."
"While SentinelOne Singularity Cloud Security offers real-time response, there is room for improvement in alert accuracy."
"I would like to see the map feature improve. It's good, but it isn't fully developed. It lets us use custom resources and policies but does not allow us to perform some actions. I would also like more custom integration and runtime security for Kubernetes."
"The categorization of the results from the vulnerability assessment could be improved."
"In the Analytics section, there is a tab for showing the severity of open issues by day. There are three options: by week, by month, and for more than thirty days. However, despite being aware of many issues open for more than thirty days, it shows no data available."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"The solution’s pricing could be improved."
"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."
"The initial setup is highly complex."
"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 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."
 

Pricing and Cost Advice

"The tool is cost-effective."
"I wasn't sure what to expect from the pricing, but I was pleasantly surprised to find that it was a little less than I thought."
"Singularity Cloud Workload Security's licensing and price were cheaper than the other solutions we looked at."
"I am personally not taking care of the pricing part, but when we moved from CrowdStrike to PingSafe, there were some savings. The price of CrowdStrike was quite high. Compared to that, the price of PingSafe was low. PingSafe is charging based on the subscription model. If I want to add an AWS subscription, I need to pay more. It should not be based on subscription. It should be based on the number of servers that I am scanning."
"I am not involved in the pricing, but it is cost-effective."
"Its pricing is constant. It has been constant over the previous year, so I am happy with it. However, price distribution can be better explained. That is the only area I am worried about. Otherwise, the pricing is very reasonable."
"PingSafe is priced reasonably for our workload."
"The pricing for PingSafe in India was more reasonable than other competitors."
"CoreOS Clair is open-source and free of charge."
"The solution's pricing is neither cheap nor very expensive."
"The product does not operate on a pay-per-license model."
"I rate the tool's pricing a three out of ten."
"I rate the product’s pricing a six out of ten."
"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."
