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.

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…

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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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."
"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."
"The solution's asset management is really great compared to Dragos or Nozomi."
"The solution's most valuable feature is the map, which shows everything that is connected and communicates with each other."
"The platform ensures security without imposing significant delays."
"The solution offers comprehensive tools that greatly enhance your IT operations if implemented correctly."
"The product helps mitigate potential threats, especially if its users have signature rules. The product also provides alerts."
"Customer service is number one and the best."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"The most valuable feature of Tenable Nessus is vulnerability detection."
"The solution is very stable."
"The initial setup of Tenable Nessus is very easy."
"The scanning capabilities are most valuable when compared to Nessus."
"The solution is the most dynamic one I have seen thus far."
"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."
"Nessus gives me a good preview of vulnerabilities and good suggestions for remediation. It's easy to find a description of a given vulnerability and solutions for it."
 

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."
"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."
"Occasionally, I face a login problem despite entering the correct password."
"There are a few protocols that Claroty doesn't currently support."
"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."
"The product could be improved in terms of user interface design."
"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 could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."
"Sometimes, the categorization for clients was tricky at first, however, they eventually got used to it."
"The professional version is not very scalable."
"The features are limited when it comes to scanning network devices for vulnerabilities."
"We'd like to see the solution embrace more user-friendliness."
"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."
"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."
"There is room, overall, for improvement in the way it groups the workstations and the way it detects, when the vulnerability is scanned. Even when we would run a new scan, if it was an already existing vulnerability, it wouldn't put a new date on it."
 

Pricing and Cost Advice

Information not available
"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 tool is quite expensive."
"The solution has a single price for unlimited assets."
"Cost-wise, it's an affordable tool."
"Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly. The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job."
"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."
"This solution is affordable."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"The price of the solution is reasonable."
"The product is free."
