Tenable Cloud Security is praised for cost-effectiveness, yielding positive ROI and satisfactory financial benefits despite limited specific metrics.
The detailed information PingSafe gives about how to fix vulnerabilities reduces the time spent on remediation by about 70 to 80 percent.
After implementing SentinelOne, it takes about five to seven minutes.
Our ability to get in and review our vulnerability stance, whether daily, monthly, weekly, or whatever it might be, has drastically improved over our prior provider.
Defender proactively indexes and analyzes documents, identifying potential threats even when inactive, enhancing preventative security.
Identifying potential vulnerabilities has helped us avoid costly data losses.
The biggest return on investment is the rapid improvement of security posture.
 

Customer Service

Sentiment score
7.8
SentinelOne Singularity Cloud Security's customer support is highly rated for responsiveness and effective issue resolution, ensuring smooth collaboration.
Sentiment score
6.6
Microsoft Defender for Cloud support is praised for expertise but criticized for delays, inconsistent service, and ticket handling issues.
Sentiment score
3.9
Tenable Cloud Security support receives mixed reviews, praised for responsiveness but criticized for delays and inconsistency in assistance.
When we send an email, they respond quickly and proactively provide solutions.
They took direct responsibility for the system and could solve queries quickly.
Having a reliable team ready and willing to assist with any issues is essential.
Since security is critical, we prefer a quicker response time.
The support team was very responsive to queries.
They understand their product, but much like us, they struggle with the finer details, especially with new features.
 

Scalability Issues

Sentiment score
8.2
SentinelOne Singularity Cloud Security excels in scalability, smoothly integrating accounts and auto-scaling, despite separate account management challenges.
Sentiment score
7.8
Microsoft Defender for Cloud is highly scalable, managing diverse environments smoothly, with seamless integration and flexible subscriptions despite cost concerns.
Sentiment score
6.4
Tenable Cloud Security is praised for its scalability and adaptability, although complex multi-cloud asset management requires improvements.
As soon as we need to add somebody, we just add them to NinjaOne, and then we have a script set up where it automatically deploys and adds them to whichever group we need.
I would rate it a 10 out of 10 for scalability.
Scalability is no longer a concern because Cloud Native Security is a fully cloud-based resource.
We are using infrastructure as a code, so we do not have any scalability issues with Microsoft Defender for Cloud implementation because our cloud automatically does it.
It has multiple licenses and features, covering infrastructures from a hundred to five hundred virtual machines, without any issues.
Defender won't replace our endpoint XDR, but it will likely adapt and support any growth in the Microsoft Cloud space.
 

Stability Issues

Sentiment score
8.2
SentinelOne Singularity Cloud Security is highly stable but experiences minor UI glitches and occasional agent-related issues.
Sentiment score
7.7
Microsoft Defender for Cloud provides a stable, reliable environment with minor performance issues primarily due to outdated systems.
Sentiment score
7.7
Tenable Cloud Security is stable with high user ratings, though some suggest minor improvements despite no major outages.
In my experience, there has been 100 percent uptime.
SentinelOne Singularity Cloud is incredibly reliable.
The cloud console is very resilient.
Defender's stability has been flawless for us.
Microsoft Defender for Cloud is very stable.
Microsoft sometimes changes settings or configurations without transparency.
 

Room For Improvement

SentinelOne Singularity Cloud needs enhanced features, stability, better reporting, integration, and support for improved user experience and efficiency.
Microsoft Defender for Cloud needs better automation, integration, user-friendliness, documentation, pricing, real-time monitoring, and legacy support.
Tenable Cloud Security needs faster operations, improved support, detailed reporting, AI integration, and easier multi-cloud implementation.
If I had to ask for anything to make it easier, it would be signed images that are GPG signed and a public repository where we can get the bits from.
If they can merge Kubernetes Security with other modules related to Kubernetes, that would help us to get more modules in the current subscription.
As organizations move to the cloud, a cloud posture management tool that offers complete cloud visibility becomes crucial for maintaining compliance.
Microsoft, in general, could significantly improve its communication and support.
It would be beneficial to streamline recommendations to avoid unnecessary alerts and to refine the severity of alerts based on specific environments or environmental attributes.
The artificial intelligence features could be expanded to allow the system to autonomously manage security issues without needing intervention from admins.
The only complaint I hear in the market is from resellers that Tenable management team in Brazil doesn't play fair with the channel and resellers.
 

Setup Cost

SentinelOne Singularity Cloud offers competitive pricing and value, with flexibility and discounts available, though costly for large deployments.
Microsoft Defender for Cloud provides flexible pricing with a free version; costs vary by features, region, and enterprise needs.
Users find Tenable Cloud Security's subscription model reasonably priced and well-suited for enterprises, offering good value compared to competitors.
With very little negotiation involved, we just let them know what we could pay and they were willing to meet us at slightly above what we paid with Sophos, which was still very fair for what we were looking at.
The price was very, very important to us, and it came down to the price when we were doing our evaluations WatchGuard and SentinelOne.
Covering our 50,000 endpoints would have nearly bankrupted most security programs, even well-funded ones like ours.
Every time we consider expanding usage, we carefully evaluate the necessity due to cost concerns.
We appreciate the licensing approach based on employee count rather than a big enterprise license.
Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters.
 

Valuable Features

SentinelOne Singularity Cloud's ease, AI detection, and seamless integration enhance IT efficiency, risk management, and forensic visibility.
Microsoft Defender for Cloud enhances security with AI detection, compliance, seamless Azure integration, and multi-cloud support for streamlined protection.
Tenable Cloud Security offers comprehensive vulnerability detection, deep cloud analysis, IAM features, and multi-cloud integration into a single dashboard.
The real-time detection and response capabilities of SentinelOne Singularity Cloud impressive because it is a platform that uses artificial intelligence to determine what is normal and what is abnormal and can lock down any virus it may encounter.
We were shown how ransomware can be immediately stopped in real-time. That was huge.
Our previous product took a lot of man hours to manage. Once we got Singularity Cloud Workload Security, it freed up our time to work on other tasks.
The most valuable feature for me is the variety of APIs available.
This feature significantly aids in threat detection and enhances the user experience by streamlining security management.
The most valuable feature is the recommendations provided on how to improve security.
Perhaps the best functionalities are related to promoting a deeper analysis of the environment where applications are running in terms of creating a double armor of security to block threats that may come in the cloud with Tenable Cloud Security.
The best features Tenable Cloud Security offers in my experience are automatic scanning, frequent scanning, and automatic finding, which I find valuable.

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.
Antonio Scola - PeerSpot reviewer
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.
