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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Zafran is an excellent tool."
"The main advantage of Claroty, when compared to its competitors, is integrated secure remote access."
"I have had a very good experience with the Claroty Platform."
"Their SRA solution, the Secure Remote Access solution, is very useful for industrial environments."
"Claroty assigns a score based on how well you are doing in the course. If you skip a video, your score decreases, making it essential to watch the content attentively."
"The tool's best feature was the UI and the simplicity it offers."
"Claroty identifies all vulnerabilities available in our environment."
"The platform ensures security without imposing significant delays."
"Customer service is number one and the best."
"The reports are pretty nice and easy to understand."
"The most valuable feature is how it scanned and detected through its database to let us know exactly what fixes we needed to put in place for the vulnerabilities. It detects and it also gives you the way to fix it."
"The support has been really cooperative."
"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."
"The initial setup of Tenable Nessus is very easy."
"I like the fact that it was not expensive. I like that it's user-friendly."
"Tenable integrates well with other solutions such as SIEM and batch management."
"It also has an executive report where you don't have to provide the client all the detail for them to sift though. But if they wish to dig through the detail they can."
 

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."
"The product's integration capabilities are an area of concern where improvements are required."
"There are a few protocols that Claroty doesn't currently support."
"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 could be improved in terms of user interface design."
"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."
"I think the only issue is that the hardware Claroty uses is expensive."
"The graphical user interface is quite poor."
"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."
"Online learning could be a bit better."
"Remediation needs improvement."
"To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"Tenable Nessus could improve by having more steady updates which will reduce the vulnerabilities."
"The reporting could be improved. The reporting in Rapid7 is much better."
"It would be nice for the professional module to include some of the reports available in the expert module."
"From my point of view the solution basically is not for the big enterprise."
 

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."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"The pricing is much more manageable versus other products."
"Tenable Nessus is affordable."
"Cost-wise, it's an affordable tool."
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"The price of the solution is reasonable."
"The solution is expensive."
