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.
OndrejKOVAC - PeerSpot reviewer
Empower clients with risk-based vulnerability management through continuous workflow and valuable insights
Tenable Security Center could improve by implementing more dynamic data displays and translating reports into European languages. This is especially relevant in Central Eastern Europe, where clients often require reports in local languages. Additionally, the licensing model could be more flexible for managed security providers, similar to a pay-as-you-go model.
Brian W. - PeerSpot reviewer
Effectively prioritizes vulnerabilities and has been one of the most transformative technologies
Prioritization is really key; it's a massive differentiator. The prioritization aspect is crucial. The ability to capture or crack credentials and then use that to move laterally and identify additional vulnerabilities is significant. Their password-cracking capability is a distinct function that is very helpful. Additionally, when a new vulnerability, such as a zero-day exploit, is identified, they review your previous scans to determine if you might be vulnerable to it, and they proactively notify you. That's a huge benefit. Also, the fact that they provide fixes alongside all their identified vulnerabilities means you don’t have to search for fixes yourself. They give you specific actions to take, which is incredibly helpful and saves a lot of time.

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."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"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."
"Zafran is an excellent tool."
"One of the most valuable features is their distributed scan model for allotting engines to work together as a pool and handle multiple scans at once, across multiple environments. Automatic scanning distribution is a distinguishing feature of their toolset."
"The usability is really good. It's very easy to use and a good platform. It is scalable and very stable. The technical support is fine and the setup is super easy."
"It allows financial institutions to compare their vulnerability management to others in the same sector."
"The solution is very intuitive and the dashboards are simple to use."
"Feature-wise, Tenable Security Center is a very fast tool with many dashboards and reports, and it covers all our systems."
"Tenable's most valuable features are the credential scan, vulnerability reports, and vulnerability ratings (VPR)."
"The scans are the most valuable aspect of this solution."
"Compared to other products, the most valuable features of the solution are its ease of use and ability to provide visibility over scan results while providing many templates to users, making it a helpful tool."
"Horizon 3's capabilities are unique, with insights and reporting that provide transparency with offensive security or red team tools the system calls."
"We experienced a threat that could have severely crippled us, but we were able to shut it down before it escalated, thanks to internal vulnerability testing and addressing critical vulnerabilities using their tool."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"Penetration testing and scans are useful features."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"The NodeZero Platform is amazing; what I love most about it is that it's automated and comparable to the manual pen testing we did with a third-party company, but with the added benefit of unlimited retesting to validate fixes."
"I rate the stability of the NodeZero Platform a ten out of ten."
 

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."
"At times we have had the typical bugs."
"Deploying Tenable.sc is highly complex because it's an on-prem solution, whereas Tenable.io is cloud-based, so you can go live as soon as you log in. Tenable.sc involves significant integration with other on-prem solutions, and the deployment takes about two to three weeks with the help of a system integrator"
"We would like to see the inclusion of external IPs and simplified reporting that's easier to deal with"
"The user interface can be improved."
"Tenable's reporting engine needs improvement. It needs to be more efficient and add more features."
"The solution should provide better web application features and support."
"The GUI could be improved to have all concerns and priorities use the same GUI, allowing them to see all tickets, assign vulnerabilities, and assign variation failures to each member of their team."
"The solution should include compliance-based scanning."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"You need to be cautious about what it scans, as it could potentially cause issues."
"The reports are quite useless."
"The rooms for improvement for The NodeZero Platform can be numerous, and they can enhance user experience."
"I encountered challenges with patch management, as we struggled to test and implement patches due to time constraints. This led to our patch management process being ineffective."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
