Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.
Deevanshi Priya - PeerSpot reviewer
Achieve certifications with progress tracking and potential for enhanced interactivity
I was using Claroty to complete training assigned by my company. The courses were self-paced and helped me get certified in two additional certifications. I plan to use it further as I have a task list for future courses. It was primarily for certification and study materials The feature I like…
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.

Quotes from Members

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

Pros

"Zafran is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Claroty is very beneficial for learning and adds value to your resume."
"The platform ensures security without imposing significant delays."
"The platform ensures security without imposing significant delays."
"The product helps mitigate potential threats, especially if its users have signature rules. The product also provides alerts."
"I like how the tool does passive and active discovery and threat detection and shows risks, recommendations, and vulnerabilities. It gives risk scores and gathers everything in one place - IP, device name, etc. We can integrate it with other tools for overall network mapping. It's useful for audits, compliance, and monitoring of all devices in the industry. It provides both monitoring and control. We also have SRA for incident response, which lets us search all alerts if we deploy the Claroty Platform."
"I believe the two main aspects where Claroty stands out are their ability to provide a complete platform and their OT-specific focus."
"The solution's asset management is really great compared to Dragos or Nozomi."
"Claroty provides continuous threat protection and identifies pre-empty stuff and false positives."
"It is easy to deploy and easy to use. Its reporting is good. From this reporting, you can see the pain point in your network, which makes it easy to fix them. It is easy to understand the reports and export them."
"I like the fact that it was not expensive. I like that it's user-friendly."
"I am impressed with the tool's vulnerability scanning."
"Tenable integrates well with other solutions such as SIEM and batch management."
"The vulnerability scanner is the most valuable feature."
"The features of Tenable Nessus that I have found most valuable are its reliability and its ability to collate a dependable output, where we are able to get the same vulnerability when we test manually. The output is quite reliable."
"It provides multiple recommendations towards the remedy of vulnerabilities."
"The product's most valuable features are vulnerability and asset management. It can define the rules and validate the configuration."
 

Cons

"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."
"There are a few protocols that Claroty doesn't currently support."
"Introducing an AI chatbot to assist you when you have doubts could be beneficial."
"The product could be improved in terms of user interface design."
"There should be AI security solutions implemented."
"There is room for improvement in the user interface to make it more vibrant and interactive, similar to IT tools."
"We face issues in the alert investigation area because it does not properly give the alert communication patterns."
"I've reported four bugs and three feature requests so far. The main area of focus should be on how attacks are detected. The attack vector information needs to be more detailed. For example, it's not enough to state that an SMB v1 version open can lead to a WannaCry attack. A more detailed explanation should help clients understand the various ways an attack could occur."
"The graphical user interface is quite poor."
"Remediation needs improvement."
"One significant drawback we encounter is the tool's tendency to flag patched packages incorrectly. For instance, if a package is patched by Debian maintainers but not updated to a major or minor version, Nessus may still flag it as vulnerable based on its database. This discrepancy leads to false alarms and requires our developers, system admins, and DevOps teams to address them."
"We'd like to see more integration potential within the solution."
"We would like to have the option of using the solution for the cloud as well as on-premises with the same license at the same time. That would be very helpful."
"The professional version is not very scalable."
"The features are limited when it comes to scanning network devices for vulnerabilities."
"The reports are okay, but the interface is a bit difficult to navigate in some cases."
"Model OS costs (and its segregation schema for individual modules)."
 

Pricing and Cost Advice

Information not available
"The tool is quite expensive."
"It's a bit expensive compared to other solutions."
"The licensing for physical devices is cheap, but the software version is expensive. The software version costs around 26-28 dollars. I was surprised and even double-checked. It was shocking."
"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."
"The solution is expensive."
"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."
"Tenable Nessus is affordable."
"The price of Tenable Nessus is too expensive for each service center."
"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
"I think the price is fairly affordable. It provides a license that is fair."
"The solution has free options."
