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.
Ondrej Kováč - PeerSpot reviewer
Has vulnerability detection, software composition analysis and asset management features
Due to its robust nature, the platform's adoption can be overwhelming initially. However, once organizations start using it, they tend to get used to it. I haven't had much direct interaction with the support team, but some partners have reported a desire for better support for the product. Another area needing improvement is the implementation complexity, especially in multi-cloud environments. Tenable Cloud Security's features mean there's a steep learning curve, which can consume significant time and resources to utilize the platform's potential and fully see immediate benefits. It's similar to AI in that you must spend time fine-tuning and training before it truly helps.

Quotes from Members

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

Pros

"Singularity Cloud Workload Security provides us with better security detection and more visibility. It is another resource that we can use to detect vulnerabilities in our company's systems. For example, it can help us detect new file processes that we are not familiar with, which could be used by attackers to exploit our systems. Singularity Cloud Workload Security can also help us diagnose and analyze data to determine whether it is malicious or not. Singularity Cloud Workload Security is like another pair of eyes that can help us protect our systems from cyberattacks."
"The offensive security where they do a fix is valuable. They go to a misconfiguration and provide detailed alerts on what could be there. They also provide a remediation feature where if we give the permission, they can also go and fix the issue."
"The ease of use of the platform is very nice."
"I would definitely recommend SentinelOne Singularity Cloud Security for infrastructure security."
"It integrates very well. We sell different products from different vendors. We know that the SentinelOne Singularity platform can be integrated with several different solutions from different vendors."
"We liked the search bar in PingSafe. It is a global search. We were able to get some insights from there."
"We like PingSafe's vulnerability assessment and management features, and its vulnerability databases."
"The solution helped free other staff to work on other projects or other tasks. We basically just had to do a bunch of upfront configuring. With it, we do not have to spend as much time in the console."
"It is very intuitive when it comes to policy administration, alerts and notifications, and ease of setting up roles at different hierarchies. It has also been good in terms of the network technology maps. It provides a good overview, but it also depends on the complexity of your network."
"The most valuable features are the monitoring of users, endpoint detection and response, and the adaptability of the AI threat intelligence engine, which quickly adapts to customizations."
"The pricing is good."
"It's got a lot of great features."
"Microsoft Defender for Cloud has significantly enhanced our overall security posture by approximately 20 to 25 percent."
"Microsoft Defender for Cloud helps in improving our overall security posture. We have a nice overview of what is missing where and what can be improved."
"Some of the most valuable features of Microsoft Defender for Cloud include its effectiveness in threat detection through unsupervised machine learning, CTI, and advanced sandboxing."
"The tool's most valuable feature is its support for cloud-native services like Kubernetes, containers, managed storage, and databases. Protecting these without Microsoft Defender for Cloud would be extremely challenging. For threat protection specifically, I find the signature-based detection and heuristic detection features very effective."
"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."
"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."
"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."
"Scanning and reporting are the most valuable features of Tenable Cloud Security"
"The product's visibility and remediation work fine for me."
"The solution’s vulnerability management feature has helped us identify and mitigate risks well."
"The tool alerts us on depreciating performance or deficiencies of our web application. It helps us react on time."
"The product's deployment phase is easy."
 

Cons

"A beneficial improvement for PingSafe would be integration with Jira, allowing for a more streamlined ticketing system."
"We repeatedly get alerts on the tool dashboard that we've already solved on our end, but they still appear. That is somewhat irritating."
"It would be really helpful if the solution improves its agent deployment process."
"We've found a lot of false positives."
"In version 2, a lot of rules have been deployed for Kubernetes security and CDR, which makes a lot of issues of critical severity, whereas they are not critical or of high severity. There is a mismatch of severities."
"There's room for improvement in the graphic explorer."
"We use PingSafe and also SentinelOne. If PingSafe integrated some of the endpoint security features of SentinelOne, it would be the perfect one-stop solution for everything. We wouldn't need to switch between the products. At my organization, I am responsible for endpoint security and vulnerability management. Integrating both functions into one application would be ideal because I could see all the alerts, heat maps, and reports in one console."
"To enhance the notification system's efficiency, resolved issues should be promptly removed from the portal."
"My experience with Microsoft Defender for Cloud has been largely negative due to a poor user experience."
"Sometimes, it's very difficult to determine when I need Microsoft Defender for Cloud for a special resource group or certain kinds of products. That's not an issue directly with the product, though."
"There is no perfect product in the world and there are always features that can be added."
"Another thing is that Defender for Cloud uses more resources than CrowdStrike, which my current company uses. Defender for Cloud has two or three processes running simultaneously that consume memory and processor time. I had the chance to compare that with CrowdStrike a few days ago, which was significantly less. It would be nice if Defender were a little lighter. It's a relatively large installation that consumes more resources than competitors do."
"For Kubernetes, I was using Azure Kubernetes Service (AKS). To see that whatever is getting deployed into AKS goes through the correct checks and balances in terms of affinities and other similar aspects and follows all the policies, we had to use a product called Stackrox. At a granular level, the built-in policies were good for Kubernetes, but to protect our containers from a coding point of view, we had to use a few other products. For example, from a programming point of view, we were using Checkmarx for static code analysis. For CIS compliance, there are no CIS benchmarks for AKS. So, we had to use other plugins to see that the CIS benchmarks are compliant. There are CIS benchmarks for Kubernetes on AWS and GCP, but there are no CIS benchmarks for AKS. So, Azure Security Center fell short from the regulatory compliance point of view, and we had to use one more product. We ended up with two different dashboards. We had Azure Security Center, and we had Stackrox that had its own dashboard. The operations team and the security team had to look at two dashboards, and they couldn't get an integrated piece. That's a drawback of Azure Security Center. Azure Security Center should provide APIs so that we can integrate its dashboard within other enterprise dashboards, such as the PowerBI dashboard. We couldn't get through these aspects, and we ended up giving Reader security permission to too many people, which was okay to some extent, but when we had to administer the users for the Stackrox portal and Azure Security Center, it became painful."
"Early on, the lack of transparency is a challenge. Microsoft does not tell you the cost when they launch something."
"The solution could improve by being more intuitive and easier to use requiring less technical knowledge."
"With the new Copilot functionality available everywhere, it is challenging to pinpoint areas for improvement. If I put in a lot of thought, I might identify things, but right now, nothing significant pops into my mind, but there is always room for more transparency, especially in pricing."
"Due to its robust nature, the platform's adoption can be overwhelming initially. However, once organizations start using it, they tend to get used to it. I haven't had much direct interaction with the support team, but some partners have reported a desire for better support for the product."
"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 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."
"The product must provide more features."
"Tenable needs to offer a patch-based solution since it is an area where the tool lacks a bit."
"I didn't find anything that wasn't useful or needed to be added."
 

Pricing and Cost Advice

"It is cheap."
"As a partner, we receive a discount on the licenses."
"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."
"It is cost-effective compared to other solutions in the market."
"PingSafe is affordable."
"It is a little expensive. I would rate it a four out of ten for pricing."
"PingSafe is less expensive than other options."
"It was reasonable pricing for me."
"Our clients complain about the cost of Microsoft Defender for Cloud."
"The tool is pretty expensive."
"Pricing is a consideration, but we strive to keep costs low by enabling only necessary services."
"The pricing model for most plans is generally good, but the cost of the new Defender for Storage plan is high and should be revisited, as it could lead to disabling desirable security features due to cost."
"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."
"This is a worldwide service and depending on the country, there will be different prices."
"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."
"It has global licensing. It comes with multiple licenses since there are around 50,000 people (in our organization) who look at it."
"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."
"The tool's price is good compared to other brands. The tool's subscription is for a year."
