Featured Reviews

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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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 saw benefits from Zafran Security almost immediately after deploying it."
"Zafran is an excellent tool."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"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."
"I believe the two main aspects where Claroty stands out are their ability to provide a complete platform and their OT-specific focus."
"Their SRA solution, the Secure Remote Access solution, is very useful for industrial environments."
"Customer service is number one and the best."
"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."
"The main advantage of Claroty, when compared to its competitors, is integrated secure remote access."
"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."
"Claroty is very beneficial for learning and adds value to your resume."
"The tool's best feature was the UI and the simplicity it offers."
"The solution provides time saving and cost saving benefits."
"The most valuable feature of Tenable Nessus is real-time monitoring."
"Quick assessments, compliance scores, and results are provided without having to do agents."
"Nessus is good at finding out what nodes you have in place. It will then provide you a report, by node, of what the vulnerabilities are. It does it quickly and stealthfully."
"I like the fact that it was not expensive. I like that it's user-friendly."
"The reports are pretty nice and easy to understand."
"It gives you an unlimited IP scan."
"The ease of use is the primary valuable feature. This specific version is very straightforward. I like the ability to modify it and configure it based on the different policies."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."
"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."
"We face issues in the alert investigation area because it does not properly give the alert communication patterns."
"Introducing an AI chatbot to assist you when you have doubts could be beneficial."
"The graphical user interface is quite poor."
"There should be AI security solutions implemented."
"I think the only issue is that the hardware Claroty uses is expensive."
"There is room for improvement in the user interface to make it more vibrant and interactive, similar to IT tools."
"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."
"If more AI features could be included with the Clarity solution, it would be feasible for everybody."
"The solution could improve by having better integration with different vendors' IPS solutions. The ACLs and IPS policies signatures should be enabled based on the results of Tenable Nessus automatically, we currently have to do it manually which is very time-consuming. It has done a good job integrating with Fortinet but we would like it to be better integrated with other solutions that we have."
"I would like to have a management option after the network scanning."
"The reports are okay, but the interface is a bit difficult to navigate in some cases."
"They could make their reporting a little better."
"The price could be reduced."
"The product must be more comprehensive."
"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."
"Model OS costs (and its segregation schema for individual modules)."
 

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."
"It's a bit expensive compared to other solutions."
"The tool is quite expensive."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"I think the price is fairly affordable. It provides a license that is fair."
"The newer tools are quite pricey. There is a case of some fine tuning that can be done in terms of licensing. The IP based licensing that is offered makes the tool very expensive. If they want the IT industry to adopt it, the price should be looked at."
"The price of Tenable Nessus could improve, it is expensive."
"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."
"The solution is worth the cost. It's a good investment."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"Our organization is huge so our license costs $30,000."
