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.

Vibhor Goel

Senior Cloud Platform Engineer at Deutsche Börse

A single tool for complete visibility and addressing security gaps

Currently, issues are structured in Microsoft Defender for Cloud at severity levels of high, critical, or warning, but these severity levels are not always right. For example, Microsoft might consider a port being open as critical, but that might not be the case for our company. Similarly, it might suggest closing some management ports, but you might need them to be able to log in, so the severity levels for certain things can be improved. Even though Microsoft Defender for Cloud provides a way to temporarily disable certain alerts or notifications without affecting our security score, it would be better to have more granularized control over these recommendations. Currently, we cannot even disable certain alerts or notifications. There should be an automated mechanism to design Azure policies based on the recommendations, possibly with AI integration. Instead of an engineer having to write a policy to fix security gaps, which is very time-consuming, there should be an inbuilt capability to auto-remediate everything and have proper control in place. Additionally, enabling Defender for Cloud at the resource group level, rather than only at the subscription level, would be beneficial.

Owner at SUNLIT TECHNOLOGIES

Offers reliable security support and encourages a safe migration to cloud environments while there is room for better reseller collaboration

I really don't know to tell the truth because we sell many solutions and don't sell exclusively Tenable, so I'm not in a condition to give a precise definition of what could be improved. My perception is this: when customer A needs Tenable Cloud Security, we introduce and demonstrate it. They POC, they appreciate it. The solution serves in such use cases ABC. I am very pragmatic and straightforward - as long as they use or want the solution, I am interested. If they don't, my question is what are the main objections? They may discuss pricing, or they may say they thought the solution had certain technical capabilities that they could not find.

Quotes from Members

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

Pros

"The multi-cloud support is valuable. They are expanding to different clouds. It is not restricted to only AWS. It allows us to have different clouds on one platform."

"You not only get to know about vulnerabilities and misconfigurations but also some of the actual"

"The UI is responsive and user-friendly."

"The UI is very good."

"Our organization is growing steadily, so our infrastructure is expanding, and we're managing more technical resources. Singularity Cloud Security helps us track our resources so that we don't get lost in the overwhelming volume of things and ensures we follow best practices. The solution gives us better visibility into our resources and enables faster resolution."

"SentinelOne Singularity Cloud Security provides email alerts and ranks issues based on severity, such as high, critical, etc., that help us prioritize issues."

"It gives me the information I need."

"SentinelOne Singularity Cloud Security offers valuable scalability suitable for organizations of all sizes, from small businesses to large enterprises."

More SentinelOne Singularity Cloud Security pros

"The solution's coordinated detection and response across devices and identities is impressive because it is complete."

"It has seamless integration with any of the services I mentioned, on Azure, such as IaaS platforms, virtual machines, applications, or databases, because it's an in-house product from Microsoft within the Azure ecosystem."

"Defender for Cloud is an improvement over Trend Micro, our previous solution. We like integrating our endpoints and visualizing everything in one place. It provides comprehensive coverage for endpoints, servers, and overall environmental security."

"The most valuable feature is that it's intuitive. It's very intuitive."

"It works seamlessly on the Azure platform because it's a Microsoft app. Its setup is similar, so if you already have a Microsoft account, it just flows into it."

"I would like to see more connectors and plugins with other platforms."

"The most valuable feature of Microsoft Defender for Cloud is its ability to assess an environment and give us a clear idea of what security components are lacking and which are not."

"The solution is quite good and addresses many security gaps."

More Microsoft Defender for Cloud pros

"Tenable Cloud Security excels in vulnerability detection, one of its strongest features. Another valuable feature is software composition analysis, which highlights and automates the detection of security flaws. Additionally, their knowledge base is excellent; if anything goes wrong, they provide clear guidance on what needs to be done to address specific vulnerabilities."

"Ermetic can provide super visibility for our cloud environment (we are using AWS)."

"The product's visibility and remediation work fine for me."

"Scanning and reporting are the most valuable features of Tenable Cloud Security"

"If you have multi-cloud tenancy using AWS and Azure, you can have a single dashboard where you can onboard all the cloud infrastructure and have visibility into it."

"The key benefit lies in having the largest and most up-to-date database. When it comes to using any Tenable product, it excels in finding vulnerabilities and providing analytics."

"The tool alerts us on depreciating performance or deficiencies of our web application. It helps us react on time."

"The solution’s vulnerability management feature has helped us identify and mitigate risks well."

More Tenable Cloud Security pros

Cons

"It does not bring much threat intel from the outside world. All it does is scan. If it can also correlate things, it will be better."

"The integration with Oracle has room for improvement."

"I used to work on AWS. At times, I would generate a normal bug in my system, and then I would check SentinelOne Singularity Cloud Security. The alert used to come after about three and a half hours. It used to take that long to generate the alert about the vulnerability in my system. If a hacker attacks a system and SentinelOne Singularity Cloud Security takes three to four hours to generate an alert, it will not be beneficial for the company. It would be helpful if we get the alert in five to ten minutes."

"Their search feature could be better."

"With Cloud Native Security, we can't selectively enable or disable alerts based on our specific use case."

"We wanted it to provide us with something like Claroty Hub in AWS for lateral movement. For example, if an EC2 instance or a virtual machine is compromised in a public subnet based on a particular vulnerability, such as Log4j, we want it to not be able to reach some of our databases. This kind of feature is not supported in SentinelOne Singularity Cloud Security."

"The alerting system of the product is an area that I look at and sometimes get confused about. I feel the alerting feature needs improvement."

"The documentation that I use for the initial setup can be more detailed or written in a more user-friendly language to avoid troubles."

More SentinelOne Singularity Cloud Security cons

"I would like to see more connectors and plugins with other platforms."

"The solution's portal is very easy to use, but there's one key component that is missing when it comes to managing policies. For example, if I've onboarded my server and I need to specify antivirus policies, there's no option to do that on the portal. I will have to go to Intune to deploy them. That is one main aspect that is missing and it's worrisome."

"After getting a recommendation, it takes time for the solution to refresh properly to show that the problem has been eliminated."

"The pricing could be improved, as it is somewhat high for smaller companies."

"Integration into other third-party products, particularly those from tier three vendors like ManageEngine and Hexcode, has proven difficult."

"Early on, the lack of transparency is a challenge. Microsoft does not tell you the cost when they launch something."

"Azure's system could be more on point like AWS support. For example, if I have an issue with AWS, I create a support ticket, then I get a call or a message. With Azure support, you raise a ticket, and somebody calls back depending on their availability and the priority, which might not align with your business priority."

"Support needs to be highly responsive, especially in large enterprise environments."

More Microsoft Defender for Cloud cons

"The product must provide more features."

"There is a need for the support team to improve their response time since it is one of the areas where the product's technical team has certain shortcomings."

"Tenable needs to offer a patch-based solution since it is an area where the tool lacks a bit."

"I have faced several bug incidents with the solution"

"Ermetic needs to improve its security scanning. I would like to see more dynamic graphical forms."

"If Tenable Cloud Security offers a complete Cnapp solution with CWP, CIEM, and Waap security, it will be able to compete with other competitors."

"I didn't find anything that wasn't useful or needed to be added."

"I do think there might be room for more integrations. This could allow for further customization and flexibility, essentially offering different functionality options to accommodate various budgets."

Pricing and Cost Advice

"Pricing is based on modules, which was ideal for us."

"PingSafe is priced reasonably for our workload."

"It was reasonable pricing for me."

"I understand that SentinelOne is a market leader, but the bill we received was astronomical."

"PingSafe is not very expensive compared to Prisma Cloud, but it's also not that cheap. However, because of its features, it makes sense to us as a company. It's fairly priced."

"We found it to be fine for us. Its price was competitive. It was something we were happy with. We are not a Fortune 500 company, so I do not know how pricing scales at the top end, but for our cloud environment, it works very well."

"The pricing for PingSafe in India was more reasonable than other competitors."

"It is cost-effective compared to other solutions in the market."

More SentinelOne Singularity Cloud Security pricing and cost advice

"The tool is pretty expensive."

"The pricing is very difficult because every type of Defender for Cloud has its own metrics and pricing. If you have Cloud for Key Vault, the pricing is different than it is for storage. Every type has its own pricing list and rules."

"The price of the solution is good for the features we receive and there is an additional cost for Microsoft premier support. However, some of my potential customers have found it to be expensive and have gone on to choose another solution."

"Understanding the costs of cloud services can be complicated at first. As with a lot of things in the cloud, it can be quite hard to understand the end cost, but it becomes clearer over time. Early on, the lack of transparency is a challenge. Microsoft does not tell you the cost when they launch something. It is clever marketing, and there is room for improvement there. There should be clarity from the start."

"Pricing depends on your workload size, but it is very cheap. If you're talking about virtual machines, it is $5 or something for each machine, which is minimal. If you go for some agent-based solution for every virtual machine, then you need to pay the same thing or more than that. For an on-premises solution like this, we were paying around $30 to $50 based on size. With Defender, Microsoft doesn't bother about the size. You pay based on the number of machines. So, if you have 10 virtual machines, and 10 virtual machines are being monitored, you are paying based on that rather than the size of the virtual machine. Thus, you are paying for the number of units rather than paying for the size of your units."

"Although I am outside of the discussion on budget and costing, I can say that the importance of security provided by this solution is of such importance that whatever the cost is, it is not a factor."

"The cost is fair. There aren't any costs in addition to the standard licensing fee."

"Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters."

More Microsoft Defender for Cloud pricing and cost advice

"The tool's pricing is fair."

"There is a need to opt for a subscription-based pricing model to use Tenable Cloud Security. I rate the product price an eight on a scale of one to ten, where one is low price and ten is high price."

"The tool's price is good compared to other brands. The tool's subscription is for a year."
