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

"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Zafran is an excellent tool."
"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."
"We saw benefits from Zafran Security almost immediately after deploying it."
"I like Tenable.sc's analytics and reporting. You can also configure your on-prem network monitors to talk to your Tenable.sc control panel."
"This product has the best results in terms of the lowest number of false-positives and false-negatives."
"Tenable SC is good for reporting and alerting. The filtering feature is also very valuable. Its integration with multiple vendors is quite good. It can be integrated with SIEM solutions and PAM solutions such as Thycotic, which is very helpful."
"The predictive prioritization features are pretty good. They do a lot of research and we trust the research that they do internally. They have knowledge of what's going on with many companies, where we only get a view into what's going on here. So the ability to get best practices out of them as part of this solution, is valuable to us."
"The solution is completely stable and operation is user-friendly."
"The Auto-Remediate feature is good."
"Support is knowledgeable."
"The tool gives us fewer false positives. Compared to its competitors, the solution’s reports are more accurate."
"For us, The NodeZero Platform is literally the single best security solution we have because the way that it works is we're able to scan every part of our network, both internally and externally, and then get completely actionable feedback that doesn't matter if it's for an application developer or a network admin."
"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."
"I rate the stability of the NodeZero Platform a ten out of ten."
"The NodeZero Platform's real attack capabilities help in identifying vulnerabilities on our on-prem systems because it provides actual vulnerabilities by attacking our systems."
"My favorite feature about The NodeZero Platform is that it's autonomous, and it truly delivers on that promise—it can be set and forgotten while it performs its tasks, and it does exactly what it claims to do."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"Penetration testing and scans are useful features."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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 pricing is reasonable, but this could be brought down more aggressively, such as we see with Rapid7, Tenable SC's main competitor."
"Support could be faster."
"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."
"Its reporting can be improved. It is not easy to generate a scan report the way we want. The data is okay, but we can't easily change the template to make it look the way we want."
"The solution needs to improve its support. I would like to see a bird's eye view of my network architecture. I would also like to see the continuous view feature in the tool."
"Additional costs are associated with using the solution, as additional scanners are required for different endpoints connected to the Tenable Security Center. If Tenable Security Center could extract information from these scanners automatically rather than manually, it would enhance user-friendliness for customers."
"I will say it's a lot slower compared to an MS scan. It takes so much longer, so the performance could definitely be worked on."
"The solution is expensive."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."
"The reports are quite useless."
"You need to be cautious about what it scans, as it could potentially cause issues."
"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."
"The areas for improvement for The NodeZero Platform involve integration and automation. It would be beneficial if it could integrate directly with vulnerability management tools that would allow the platform to automatically import data, identify vulnerable systems, and test targets immediately, potentially even enabling automated feedback loops for rescanning since the process is currently manual."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
