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.

The technical support is good yet could improve in terms of response time.
 

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
Prisma Cloud scales well across environments, integrates seamlessly, and automates operations, though costs rise with increased licenses.
Sentiment score
5.2
Tenable Nessus efficiently scales for small to mid-sized enterprises but large-scale expansion requires extra planning and resources.
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.
It's very scalable and very easy to use.
It's scalable.
The scalability is also a 10 out of 10.
Whether managing 50 servers today or 500 tomorrow, performance or capacity are not hindered.
Tenable Nessus is definitely scalable, especially for license formats designed for scalability.
 

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
8.0
Prisma Cloud offers reliable performance and stability, effectively handling environments with rare interruptions and quickly resolved issues.
Sentiment score
5.3
Tenable Nessus is stable and reliable, with efficient scanning, minor configuration challenges, and maintains a strong reputation.
No lag, no crashing, no downtime.
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.
I would rate it a ten out of ten for stability.
Prisma Cloud is a stable platform.
The solution is stable and is capable of covering large enterprises.
We have not encountered any issues with missing network items or errors in API and webhook interactions.
 

Room For Improvement

SentinelOne Singularity Cloud needs enhanced features, stability, better reporting, integration, and support for improved user experience and efficiency.
Prisma Cloud needs improvements in documentation, UI, automation, integrations, pricing, and support, with challenges in compliance and cloud support.
Tenable Nessus needs improvements in reporting, interface, integration, licensing flexibility, and enhanced detection accuracy for better user satisfaction.
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.
From a developer's perspective, especially for organizations like banks developing their applications, ensuring API security before deploying them to the cloud is crucial.
Prisma Cloud is an excellent tool.
Even though documentation was available, it took a while for a new person to understand what integration meant, what will be achieved after the integration, or how the integration needed to be done on the Azure or AWS side.
This is Tenable's property. They want to sell Tenable Security Center, and they closed all the API capability for Tenable Nessus Professional.
The documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional.
The product's pricing has roughly tripled within the last couple of years, making us reconsider renewing the license for the scanner.
 

Setup Cost

SentinelOne Singularity Cloud offers competitive pricing and value, with flexibility and discounts available, though costly for large deployments.
Prisma Cloud is expensive but valued for comprehensive security, flexible licensing, and potential cost savings in multi-cloud environments.
Tenable Nessus is competitively priced, seen as affordable for its features, with flexible licensing and potential for discounts.
Covering our 50,000 endpoints would have nearly bankrupted most security programs, even well-funded ones like ours.
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.
The cost was not on the higher side.
That's why a lot of our clients are shifting from cloud-native to Prisma Cloud: because of its effectiveness and because it is budget-friendly as well.
The solution is very expensive.
The pricing for Tenable Nessus has increased significantly, tripling over the last few years.
Tenable Nessus's pricing is adequate if it is fully utilized.
My experience with the pricing, setup cost, and licensing of Tenable Nessus is that the installation is somewhat easier, but preparing the product, such as the SKU and license options, is quite tricky.
 

Valuable Features

SentinelOne Singularity Cloud's ease, AI detection, and seamless integration enhance IT efficiency, risk management, and forensic visibility.
Prisma Cloud enhances security with dynamic identity creation, compliance management, and integration across AWS and CI/CD pipelines.
Tenable Nessus excels with comprehensive vulnerability detection, user-friendly interface, scalability, real-time monitoring, integration, and affordable pricing.
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 automation capabilities are excellent.
With this product, we can monitor all the things even if they are on different clouds - and it can be done on one platform.
What I like most about Prisma Cloud is its zero-day signatures, maximum security, minimal downtime, cloud visibility, control, and ease of deployment.
The scanning and reporting features are the most valuable aspects of Tenable Nessus.
The most valuable features of Tenable Nessus include its ease of access and quick usability.
The features I personally like include host discovery.

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.
Harsh_Vardhan - PeerSpot reviewer
Provides visibility and control that our customers need
Different modules are valuable for different customers. We are leveraging CSPM. It is one of the best solutions for comprehensive visibility into cloud resource configurations and compliance. It has a lot of out-of-the-box policies, and the visibility that we are getting is impressive. The DSPM module is valuable. This is the latest one that Palo Alto procured from Dig Security. No competitor provides this functionality in a single pane of glass. The support for Linux and container security is also very good. That is the beauty of Prisma Cloud. However, in terms of Windows security, Prisma Cloud is lacking because currently, there is no runtime protection available. The UI is very good. We get all the things within a single UI. It is easy to use. A new user can easily understand it. It is very user-friendly.
HarshBhardiya - PeerSpot reviewer
Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.
