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.
Chethan Gowda - PeerSpot reviewer
Have maintained accurate vulnerability scans and gained actionable remediation insights across thousands of servers
Tenable Vulnerability Management agents are very lightweight, and the results we get are very accurate. The solutions they provide to us, assuming if one vulnerability exists, there will be a solution. The resolution they give us in wording will be the best solution. The exploit rates and the reports we get provide a lot of information, making it very easy for us to verify.The main benefit of integration with Tenable Vulnerability Management is that there will be no lack of missing vulnerabilities when it comes to the patching environment. That is one of the key aspects of why we have integrated Tenable to our patching tools. It has a vast capacity of pushing the data to our tools due to its capability and compatibility. That is also one of the reasons why we are using Tenable Vulnerability Management.
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."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"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 is an excellent tool."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"They are on a good trajectory as a company and investing in R&D in the right ways."
"It's a recommended tool for penetration testers because it's effective for that purpose."
"It helps us create remediation projects and assign the console’s responsibility to specific engineers."
"The most valuable feature for me is container scanning because I am interested in CICD security."
"The vulnerability management itself is the most valuable feature as well as references to the mitigation techniques."
"Tenable.io, in particular, is quite a powerful product. It looks at your traditional environment, which is pretty much anything that is on-premises, and it also goes a step ahead and covers your modern assets, which is anything that is currently sitting in the cloud. You get complete visibility of your entire environment and tech operation. The ability to give you visibility across the entire tech surface is one of the biggest advantages that Tenable.io has."
"The initial setup is straightforward so long as your infrastructure, components, and networks are in place."
"There is no burden of updating or upgrading this solution."
"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."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"The NodeZero Platform's real attack capabilities help identify vulnerabilities on my on-premise systems by adding an element of validation and offensive security testing on top of known vulnerabilities. The feature that allows security teams to fix and retest vulnerabilities instantly is very useful, even though it may not happen literally 'instantly.' It's a necessary tool for any organization to understand whether vulnerabilities are genuinely exploitable by attackers. With its near-real-time testing capabilities, it's an essential part of any security portfolio."
"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."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"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."
"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."
 

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 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."
"We'd like to see a bit more user-friendliness."
"The one drawback that we have found is the reports."
"The UI has room for improvement."
"The tool's reports are bad. They're not very customizable or flexible. During audits, we often have to exclude things that aren't relevant to our organization, but we can't do that easily with the reports. They come in HTML or PDF format, and we can't compare current results with previous ones in Excel because we never receive reports in Excel."
"AI integration for reporting in Tenable would be beneficial."
"The price could be lower."
"It would be helpful if Tenable could be more clear with regard to everything the solution can and cannot do with the particular license that you have."
"I don't recommend Tenable.io Vulnerability Management for web scanning"
"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."
"The speed of the scans takes some time, but in my opinion, it is not surprising for what it is doing."
"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."
"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."
"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
"Sometimes even their support doesn't know why we're seeing certain issues."
