Featured Reviews

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.
Vibhor Goel - PeerSpot reviewer
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.

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

"SentinelOne Singularity Cloud Security offers valuable features like runtime notifications. These alerts come to my account, ensuring that if any port or component within my infrastructure is opened or compromised, I am informed immediately. It highlights issues within minutes or even seconds."
"Singularity Cloud's ability to create custom correlation searches and reduce noise is highly valuable."
"SentinelOne Singularity Cloud Security's most valuable feature is its unified console."
"SentinelOne is far superior to our previous solution, Accops, due to its seamless updates, effortless maintenance, and user-friendly interface and dashboard."
"SentinelOne Singularity Cloud Security's graph explorer is a valuable tool that lets us visualize all connected services."
"We're monitoring several cloud accounts with Singularity. It is convenient to identify issues or security failures in any account. It's nice to have all the details we need to solve these issues."
"The most valuable feature is the easy-to-understand user interface, which allows even non-technical users to comprehend and resolve issues."
"SentinelOne stands out with its responsiveness to feature requests for Singularity Cloud Security."
"Microsoft Defender for Cloud has improved our security poster by at least 100 percent."
"The most valuable feature is the recommendations provided on how to improve security. It has made the cloud environment more secure, thanks to all the recommendations we can get."
"The most valuable features of this solution are the vulnerability assessments and the glossary of compliance."
"Microsoft Defender for Cloud has definitely helped us manage and secure our multi-cloud environment by providing ease of use."
"The most valuable feature is the hunting feature, which integrates well into the entire Microsoft ecosystem."
"It's got a lot of great features."
"The most valuable features of the solution are the insights, meaning the remediation suggestions, as well as the incident alerts."
"Microsoft Defender for Cloud has significantly enhanced our overall security posture by approximately 20 to 25 percent."
"The solution’s vulnerability management feature has helped us identify and mitigate risks well."
"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."
"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 product's deployment phase is easy."
"The product's visibility and remediation work fine for me."
"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."
"Scanning and reporting are the most valuable features of Tenable Cloud Security"
 

Cons

"The cost has the potential for improvement."
"There should be more documentation about the product."
"A beneficial improvement for SentinelOne Singularity Cloud Security would be integration with Jira, allowing for a more streamlined ticketing system."
"SentinelOne Singularity Cloud Security is an excellent CSSPM tool, but the CSC CWPP features need improvement."
"We are experiencing problems with Cloud Native Security reporting."
"I believe the UI/UX updates for SentinelOne Singularity Cloud Security have room for improvement."
"I have noticed that the dashboard occasionally gets stuck, potentially due to internet issues. It could benefit from enhancements to be more robust and smoother."
"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 most significant areas for improvement are in the security of our identity and endpoints and the posture of the cloud environment. Better protection for our cloud users and cloud apps is always welcome."
"Azure Security Center takes a long time to update, compared to the on-premises version of Microsoft Defender."
"Integration into other third-party products, particularly those from tier three vendors like ManageEngine and Hexcode, has proven difficult."
"An area where Microsoft Defender for Cloud could be improved is in getting away from having multiple menus that do the same thing, which seems imposing when looking at it."
"Microsoft Defender for Cloud could be improved by adding capabilities for NetApp files and more PaaS resources from other vendors, not just Microsoft."
"I would like to see more connectors and plugins with other platforms."
"I felt that there was disconnection in terms of understanding the UI. The communication for moving from the old UI to the new UI could be improved. It was a bit awkward."
"The cost is always a concern, but overall, it's not too bad because it is easy to use and pretty friendly."
"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."
"Tenable needs to offer a patch-based solution since it is an area where the tool lacks a bit."
"Ermetic needs to improve its security scanning. I would like to see more dynamic graphical forms."
"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."
"The product must provide more features."
"I have faced several bug incidents with the solution"
"I didn't find anything that wasn't useful or needed to be added."
"If Tenable Cloud Security offers a complete Cnapp solution with CWP, CIEM, and Waap security, it will be able to compete with other competitors."
 

Pricing and Cost Advice

"While I'm slightly out of touch with pricing, I know SentinelOne is much cheaper than other products."
"PingSafe is affordable."
"The tool is cost-effective."
"Their pricing appears to be based simply on the number of accounts we have, which is common for cloud-based products."
"It's not expensive. The product is in its initial growth stages and appears more competitive compared to others. It comes in different variants, and I believe the enterprise version costs around $55 per user per year. I would rate it a five, somewhere fairly moderate."
"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."
"While SentinelOne Singularity Cloud Security offers robust protection, its high cost may be prohibitive for small and medium-sized businesses."
"It is cheap."
"Currently, Microsoft offers only one plan at the enterprise level which is $15 per machine."
"It has global licensing. It comes with multiple licenses since there are around 50,000 people (in our organization) who look at it."
"Defender for Cloud is pretty costly for a single line. It's incredibly high to pay monthly for security per server. The cost is considerable for an enterprise with 500-plus virtual machines, and the monthly bill can spike."
"Microsoft's licensing and pricing are sometimes complicated. If someone is new to Microsoft's licensing, they might have difficulty with it."
"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."
"I'm not privy to that information, but I know it's probably close to a million dollars a year."
"The pricing and licensing of Microsoft Defender for Cloud have been good for us. We appreciate the licensing approach based on employee count rather than a big enterprise license."
"Azure Defender is definitely pricey, but their competitors cost about the same. For example, a Palo Alto solution is the same price per endpoint, but the ground strikes cost a bit more than Azure Defender. Still, it's pricey for a company like ours. Maybe well-established organizations can afford it, but it might be too costly for a startup."
"The tool's price is good compared to other brands. The tool's subscription is for a year."
"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 pricing is fair."
