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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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 provides continuous threat protection and identifies pre-empty stuff and false positives."
"The solution offers comprehensive tools that greatly enhance your IT operations if implemented correctly."
"I appreciate the active coding, deep inspection of packages, and data retrieval. The tool covers information about assets and attack vectors, which I find superior to other tools. Based on alerts, I create reports detailing how an attacker can penetrate the plant, both externally and internally."
"The platform ensures security without imposing significant delays."
"The tool's best feature was the UI and the simplicity it offers."
"The platform ensures security without imposing significant delays."
"The solution's most valuable feature is the map, which shows everything that is connected and communicates with each other."
"The solution's asset management is really great compared to Dragos or Nozomi."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"A valuable feature of the solution is that it is easy to understand."
"We have around 500 virtual machines. Therefore, we conduct monthly scans and open tickets for our developers to address identified vulnerabilities. These scans cover the servers, other network equipment, and appliances in our infrastructure."
"We looked at Tenable, Qualys and Rapid7. We found Tenable was the best of all three."
"I like the fact that it was not expensive. I like that it's user-friendly."
"Once you get past the initial implementation, the solution is very stable."
"The automatic scanner and scheduler are pretty cool."
"The most valuable features are that it's fast, it's easy to use and it provides good reports."
 

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."
"Claroty Platform only gives the vulnerabilities based on the make and model of the devices, so it doesn't provide any resolution or any detailed explanation of how one can resolve such issues."
"Claroty Platform could improve the pricing to get more acceptability in the market."
"If more AI features could be included with the Clarity solution, it would be feasible for everybody."
"For improvement, I think the training could be more practical. We have external training, but they're mostly theoretical. I want the solution to provide hands-on lab experience to help users learn better."
"The graphical user interface is quite poor."
"There is room for improvement in the user interface to make it more vibrant and interactive, similar to IT tools. Improvements could also be made in the Secure Remote Access (SRA) user interaction and graphical representations of recordings."
"The product's integration capabilities are an area of concern where improvements are required."
"There is room for improvement in the user interface to make it more vibrant and interactive, similar to IT tools."
"Multiple user access would be an area for improvement from a user-access perspective. A role-based access control feature would be great because at present, there is a limitation with only one account. If that account gets compromised or gets locked, then we will encounter problems."
"Model OS costs (and its segregation schema for individual modules)."
"It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."
"Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings."
"We'd like to see more integration potential within the solution."
"The reporting could be improved. The reporting in Rapid7 is much better."
"EQA's and dashboards should be addressed in the next release."
"I have found it is sometimes difficult to control the Zoom meeting sessions. For example, it is difficult to know who is talking and when trying to mute everyone but the speaker you end up muting everyone. When using multiple screens it is laborious to find the control buttons, such as to start a session. Additionally, when a recording is done I have found it difficult to find them, there should be an easier way to retrieve them."
 

Pricing and Cost Advice

Information not available
"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."
"The tool is quite expensive."
"It's a bit expensive compared to other solutions."
"We pay approximately $2,500 on a yearly basis."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"I would like to see better discounts."
"I think the price is fairly affordable. It provides a license that is fair."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"The cost is around $4,300 per year. Use is unlimited. You don't pay more if you want to use it for another IP."
"This solution is affordable."
"The product is free."
