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

"The UI is very good."
"Cloud Native Security is user-friendly. Everything in the Cloud Native Security tool is straightforward, including detections, integration, reporting, etc. They are constantly improving their UI by adding plugins and other features."
"When creating cloud infrastructure, Cloud Native Security evaluates the cloud security parameters and how they will impact the organization's risk. It lets us know whether our security parameter conforms to international industry standards. It alerts us about anything that increases our risk, so we can address those vulnerabilities and prevent attacks."
"We like the platform and its response time. We also like that its console is user-friendly as well as modern and sleek."
"Cloud Native Security offers attack path analysis."
"PingSafe has a dashboard that can detect the criticality of a particular problem, whether it falls under critical, medium, or low vulnerability."
"I rate SentinelOne Singularity Cloud Security ten out of ten."
"The most valuable feature is the ability to gain deep visibility into the workloads 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."
"CoreOS Clair's best feature is detection accuracy."
"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."
"It is a scalable solution. Scalability-wise, it is a good solution."
"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."
"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."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
 

Cons

"A beneficial improvement for PingSafe would be integration with Jira, allowing for a more streamlined ticketing system."
"From my personal experience, the alerting system needs to be faster. If something happens in our infrastructure, the alert appears on the dashboard, but I have to log in to the dashboard and refresh it."
"For vulnerabilities, they are showing CVE ID. The naming convention should be better so that it indicates the container where a vulnerability is present. Currently, they are only showing CVE ID, but the same CVE ID might be present in multiple containers. We would like to have the container name so that we can easily fix the issue."
"The SentinelOne customer support needs improvement, as they are sometimes late in responding, which is critical in a production issue."
"They can add more widgets to its dashboard. A centralized dashboard with numerous metrics would improve user understanding."
"SentinelOne Singularity Cloud Security has limited legacy system support and may not fully support older operating systems or legacy environments."
"The documentation could be better."
"To enhance the notification system's efficiency, resolved issues should be promptly removed from the portal."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"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."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"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."
"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 solution’s pricing could be improved."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
 

Pricing and Cost Advice

"I would rate the cost a seven out of ten with ten being the most costly."
"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."
"PingSafe falls within the typical price range for cloud security platforms."
"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."
"SentinelOne is quite costly compared to other security platforms."
"We have an enterprise license. It is affordable. I'm not sure, but I think we pay 150,000 rupees per month."
"It is cheap."
"I understand that SentinelOne is a market leader, but the bill we received was astronomical."
"CoreOS Clair is open-source and free of charge."
"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."
"I rate the tool's pricing a three out of ten."
"The solution's pricing is neither cheap nor very expensive."
