The platform is not famous for being cheap. It is quite expensive, but we know that we have the protection, so there is enough value for what we pay for.
Reputation and data security are the two most important things to a financial institution.

Whenever I have issues with the solution, I will get an immediate response from the product team and they will try to close the issue as soon as possible.
When you send them a message, you get a response in a minute or two.
They can respond with technical documentation or pass on the case to the next level because it requires the development of a new feature or changing a feature due to a bug.
Whenever any issue arises, we contact the support, and they are always there for us.
The technical support is good yet could improve in terms of response time.
Technical support for Tenable Nessus is very good.
 

Scalability Issues

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 by Palo Alto Networks offers scalable, flexible performance across multi-cloud environments, supporting seamless expansion and integration.
Sentiment score
5.7
Tenable Nessus scales efficiently, suiting small enterprises; larger ones may face challenges, especially with vast user data management.
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.
It's very scalable and very easy to use.
I am highly impressed with the product's scalability.
It's scalable.
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 is generally stable with minimal issues, rare downtimes, and is highly rated by users for reliability.
Sentiment score

I cannot recall any downtime with the solution.
I would rate it a ten out of ten for stability.
Prisma Cloud is stable.

Room For Improvement

SentinelOne Singularity Cloud needs enhanced features, stability, better reporting, integration, and support for improved user experience and efficiency.
Prisma Cloud needs better documentation, usability, automation, security features, customizable reports, and faster support for improved efficiency.
Tenable Nessus needs enhanced reporting, cloud integration, user experience, vulnerability prioritization, customization, and pricing for improved performance.
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.
It is a SaaS solution, but some of my clients have a local regulatory requirement, and they want to install it locally on their premises.
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.
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's higher pricing is justified by its comprehensive features, but licensing complexity concerns some enterprise buyers.
Tenable Nessus offers competitively priced annual subscriptions, with costs varying by the number of scanned hosts and no hidden fees.
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.
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 offers multi-cloud security with compliance, automation, CI/CD integration, and quick threat response via a centralized platform.
Tenable Nessus offers comprehensive vulnerability scanning, user-friendly interface, effective integrations, and affordability, making it a preferred choice.
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.
We could spread the Prisma Cloud platform to 16 countries without encountering any kind of problem.
Prisma Cloud provides risk clarity at runtime and across the entire pipeline, like, showing issues as they're discovered during the build phases.
Identifying misconfigurations and vulnerabilities at the first stage itself will help the organization save time and money - which is highly appreciated.
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

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.
Mohammad Qaw - PeerSpot reviewer
It gives you one console to see all of your assets, review their configurations, and build your processes
Most customers use Prisma Cloud for visibility and compliance. Prisma has so many features, but many organizations do not use them. They primarily use the visibility part to connect all their cloud accounts and hosts for visibility to see if they are missing any security controls or if they have any misconfigurations. You can connect it to cloud environments such as Azure, AWS, Oracle Cloud, Alibaba, etc., or to an on-prem data center. Prisma Cloud gives you so many options to automate processes related to your daily operations. When it comes to cybersecurity, you can automate things with their existing APIs. They also have out-of-the-box integrations with many solutions. I have not seen any limitations. Everything is customizable. You can do whatever you want, defining the reporting and custom use cases. They recently updated the UI, so it's much better than before.
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.
