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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"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 is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We saw benefits from Zafran Security almost immediately after deploying it."
"The tool's best feature was the UI and the simplicity it offers."
"Their SRA solution, the Secure Remote Access solution, is very useful for industrial environments."
"The solution offers comprehensive tools that greatly enhance your IT operations if implemented correctly."
"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."
"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."
"Customer service is number one and the best."
"The most valuable feature of Tenable Nessus is real-time monitoring."
"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."
"It does exactly what you expect it to do, and its pricing is great. We couldn't really ask for a better deal."
"Tenable Nessus has provided increased visibility across the organization's servers."
"The solution can scale well."
"Security is the key number because it can start to scan with a few clicks instead of credits, which is a bit complicated. So simplicity is the first advantage. Then the generated reports are well done and easy to present to management. The quality of the scan is quite good in detecting the severity. The solution has simplicity. Also, it has frequent updates so that is also a valuable feature."
"Nessus' most valuable feature is vulnerability management because it helps to discover vulnerabilities proactively and integrates with patch management solutions so you can push patches."
"The vulnerability scanner is the most valuable feature."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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."
"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."
"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."
"I think the only issue is that the hardware Claroty uses is expensive."
"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."
"There are a few protocols that Claroty doesn't currently support."
"Occasionally, I face a login problem despite entering the correct password."
"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."
"Claroty Platform could improve the pricing to get more acceptability in the market."
"EQA's and dashboards should be addressed in the next release."
"Model OS costs (and its segregation schema for individual modules)."
"There is room for improvement in finishing the transition to the cloud. We'd like to see them keep on improving the Tenable.io product, so that we can migrate to it entirely, instead of having to keep the Tenable.sc on-prem product."
"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."
"They should improve the I/O reporting and the customized spreadsheet export feature."
"We'd like to see the solution embrace more user-friendliness."
"The reports are okay, but the interface is a bit difficult to navigate in some cases."
"The price could be reduced."
 

Pricing and Cost Advice

Information not available
"The tool is quite expensive."
"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 price of the solution is reasonable."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"It has a fair cost and very good cost-benefit ratio."
"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."
"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."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"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."
