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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran is an excellent tool."
"We saw benefits from Zafran Security almost immediately after deploying it."
"The most valuable feature of SentinelOne Singularity Identity is its ability to detect based on behavior rather than just static signatures."
"The product's initial setup phase is straightforward."
"The AI provides a futuristic ML model. That helps a lot when it comes to shifting security approaches and hep better forecast attacks."
"One of the top things we're interested in is cloud protection."
"Incident response is one of the key areas where the solution has been very useful. Whenever there is an incident, instead of being reactive, the government is now able to quickly gain the data that it needs to see what its end agency is also seeing and partner with them in real-time to look at the same data and to collaborate where needed, empowering the agency to be able to do their job."
"SentinelOne enhances our customers' risk management."
"The threat detection capability is the most valuable feature."
"SentinelOne stands out due to its AI capabilities, which lead to excellent prevention."
"The most valuable features of Tenable Nessus include its ease of access and quick usability."
"Tenable Nessus has a good performance, is very user-friendly, and is easy to use."
"Tenable Nessus streamlines the process of scanning for our organization."
"A valuable feature of the solution is that it is easy to understand."
"Tenable Nessus is an absolutely stable and fantastic product."
"Its initial setup was simple and straightforward."
"Makes ransomware checking and OS auditing and implementation relatively easy."
"The initial setup is very straightforward."
 

Cons

"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."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"The first-level support has room for improvement."
"Sometimes I get kicked out of the console. I don't know why."
"A lot of those features came from an acquisition of a different company."
"One area for improvement would be the self-healing nature of the agent."
"Agent connectivity can be improved, as it is one aspect of the product with certain shortcomings."
"Support could be faster. They need a faster response time."
"The solution's query resolution time could be reduced further, and a faster resolution could be provided."
"The primary reason for this discontent is that we frequently encounter performance issues with our servers."
"EQA's and dashboards should be addressed in the next release."
"The reporting could be improved. The reporting in Rapid7 is much better."
"They could make their reporting a little better."
"Model OS costs (and its segregation schema for individual modules)."
"Vulnerability recommendations are outdated and not in line with industry standards."
"Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings."
"Multiple user access would be an area for improvement from a user-access perspective. A role-based access control feature would be great because at present, there is a limitation with only one account. If that account gets compromised or gets locked, then we will encounter problems."
"Tenable Nessus could improve the reporting."

"As a SentinelOne partner, we offer competitive pricing on comprehensive packages that include the SentinelOne license, our management services, and a proof-of-concept to ensure the technology meets your needs."
"The price is reasonable."
"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."

"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"Tenable Nessus is affordable."
