Sentiment score
3.4
Tenable Cloud Security support receives mixed reviews with praised efficiency and availability, but some note delayed and inconsistent assistance.

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.
With Element, if you need a feature, you can discuss it with them, and if implementation is possible, you will have that feature within a month or two, depending on complexity.
 

Scalability Issues

Sentiment score
5.8
Tenable Cloud Security excels in scalability, praised for handling assets efficiently, but faces challenges in larger multi-cloud setups.
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.
I would rate the scalability of PingSafe 10 out of 10.
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 stable and reliable, with occasional UI lags but generally praised for consistent performance.
Sentiment score
7.6
Microsoft Defender for Cloud is stable and reliable, with minimal issues mainly during updates, ensuring strong user satisfaction.
Sentiment score
7.8
Tenable Cloud Security is stable and reliable, with high ratings and prompt resolution of minor bugs, say users.
It's a reliable solution that the organization is increasingly adopting for its robust features and security.
We contacted Cloud Native Security, and they addressed it in a day.
The only downtime we had was when switching from V1 to V2 but it was smooth.
Defender's stability has been flawless for us.
Microsoft Defender for Cloud is very stable.
Microsoft sometimes changes settings or configurations without transparency.
In situations where there was a platform issue, they fixed it immediately and provided a complete explanation for the occurrence.
 

Room For Improvement

SentinelOne Singularity Cloud Security needs enhancements in affordability, integration, support, customization, documentation, and performance for improved user experience.
Microsoft Defender for Cloud users seek better automation, clarity, integration, AI features, and comprehensive analytics for improved security management.
Tenable Cloud Security needs improved speed, automation, integration, clearer licensing, better support, and AI-powered features for multi-cloud environments.
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.
I would also like to see Cloud Native Security offer APIs that allow us to directly build dashboards within the platform.
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.
Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable.
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 is competitively priced but perceived as costly for larger deployments and possibly unsuitable for smaller businesses.
Microsoft Defender for Cloud is scalable, offering free and paid versions with costs averaging $15 monthly per server.
Tenable Cloud Security is favorably received for its fair pricing, offering good value for enterprise cloud security solutions.
I believe the enterprise version costs around $55 per user per year.
There are some tools that are double the cost of Cloud Native Security.
I recall Cloud Native Security charging a slightly higher premium previously.
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 excels in ease of use, real-time detection, automated remediation, and seamless integration, enhancing security operations efficiently.
Microsoft Defender for Cloud enhances security with AI-based threat detection, multi-cloud support, and a unified portal for comprehensive management.
Tenable Cloud Security offers comprehensive vulnerability detection, asset management, and integration, enhancing security and compliance with proactive monitoring.
This helps visualize potential attack paths and even suggests attack paths a malicious actor might take.
The infrastructure-as-code feature is helpful for discovering open ports in some of the modules.
This tool has been helpful for us. It allows us to search for vulnerabilities and provides evidence directly on the screen.
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.
The automatic integration capabilities, particularly with DNS, Azure, and AWS, are extremely valuable.
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

Ritesh P. - PeerSpot reviewer
It's more scalable and flexible than our previous solution because we don't need to install any agents
The reporting works well, but sometimes the severity classifications are inaccurate. Sometimes, it flags an issue as high-impact, but it should be a lower severity. For example, it might highlight an exposed AWS encryption key, a critical compliance issue, but it isn't tagged as a high-risk problem. That only happens about 10 percent of the time. It shows a true positive 80-90 percent of the time.
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.
