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.
Roftiel Constantine - PeerSpot reviewer
Provides proactive threat remediation, reduces alert volume, and enhances incident response capabilities
During our pre-purchase evaluation of SentinelOne's EDR capabilities three years ago, we were consistently impressed by the positive relationships customers reported having with SentinelOne's engineers, sales teams, and customer success managers. These strong relationships, evident in the customers' unsolicited feedback, highlighted the "soft skills" and intangible qualities that SentinelOne possessed. This positive customer experience has been mirrored in our own interactions with them. Their responsiveness to our needs, particularly when addressing a couple of challenges we faced, has been excellent. They proactively scheduled weekly meetings to demonstrate their commitment to resolving our issues, a customer-centric approach I admire. SentinelOne's dedication to customer service, including their rapid technology updates and responsiveness to our suggestions, has been crucial to our success in protecting our organization. Their ability to quickly incorporate our needs into new releases is truly impressive and sets them apart. Overall, I highly recommend SentinelOne based on our positive interactions across all levels of their organization.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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."
"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."
"The most valuable feature of SentinelOne Singularity Identity is its ability to detect based on behavior rather than just static signatures."
"The XDR capabilities are very good."
"The AI-based detection, scanning, prevention and mitigation features are the most valuable features."
"SentinelOne Singularity Identity is very lightweight as an agent or software."
"The protection provided by SentinelOne Singularity Identity is the most valuable feature."
"They have different levels of support. We have the highest level where they are constantly checking all the endpoints. If at any certain point, they identify that a computer has been triggered by a virus, a link, or something else, they would automatically tell us that within 15 seconds. If they notice something, they automatically send us an email saying that they noticed something in the computer, and they are going to block it."
"SentinelOne enhances our customers' risk management."
"The effectiveness of their AI and behavioral analysis helps mitigate zero-day activities and detect new threats."
"The most valuable feature is the breadth of vulnerabilities that it finds. It's able to find across a lot of different platforms and operating systems. It's also able to combine local testing with network-based testing."
"The most valuable feature of Tenable Nessus is the GUI and user-friendliness. Additionally, the environment is easy to work with."
"I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for."
"We looked at Tenable, Qualys and Rapid7. We found Tenable was the best of all three."
"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 plug-in text information is quite useful."
"The most valuable aspect of this solution is that you receive the entire report, which details the breakdown, especially in terms of critical, high, low, and mediums."
"I have experience with it on my attack stations, and it's pretty good to optimize. Personally, I think Nessus is quite a good product."
 

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 UI can be more user-friendly."
"One area for improvement would be the self-healing nature of the agent."
"Sometimes I get kicked out of the console. I don't know why."
"The solution's query resolution time could be reduced further, and a faster resolution could be provided."
"The policies could be more precise, and Singularity should use more templates like alternative solutions have. Endpoint management is poor. We cannot manage individual endpoints and must rely on policies, exclusions, or block lists to apply settings to a group instead of the individual agent. If I have to make settings for one computer, I need to create a group, apply the configuration, and move the agent there. It's challenging to manage endpoints that way."
"Support could be faster. They need a faster response time."
"I don't like SentinelOne's reporting tools. Their reports seem fine theoretically, but the issue is the sample size. For example, it will report that there were four incidents, and that equals 25 percent fewer incidents compared to the previous months. It would be a great improvement if I could expand the range to see reports for the last six months, but it's always one month. That would be an easy thing for them to resolve."
"There is a clear roadmap for improvements, including enhancing capabilities with AI and seamless functionality in an MSP model for deeper visibility across multiple agencies. Further development is anticipated to continue enhancing the solution."
"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."
"They should improve the I/O reporting and the customized spreadsheet export feature."
"The price and scalability of the solution could improve."
"Technically, it is an excellent and the best solution available in Libya. My only concern is related to its pricing. They are an emerging company in Libya, and they need to put in some effort to provide us with very good prices so that customers can go with the best solution. Chinese companies are getting into the market here, and they're providing very cheap solutions."
"The tool needs to upgrade asset tracking."
"They need more flexible pricing."
"The solution should be able to support more devices."
"Consumes more system resources when it's running."
