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.

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.

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 are able to see the real risk of a vulnerability on our environment with our security tools."

"We saw benefits from Zafran Security almost immediately after deploying it."

"Zafran has become an indispensable tool in our cybersecurity arsenal."

"Zafran is an excellent tool."

"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."

"This solution has a much lower rate of false positives compared to competing products."

"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."

"The initial setup process is simple."

"It basically reviews our threat landscape vulnerability."

"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."

"The valauble feature is compliance reporting system."

More Tenable Security Center pros

"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."

"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."

"Penetration testing and scans are useful features."

"After the third party conducts the pen test, The NodeZero Platform is run, and it finds the same things they found and sometimes a few other things that they did not even identify."

"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."

"Overall, I'd rate NodeZero at nine to 9.5 out of ten."

"Honestly, it's one of the most transformational technologies we've implemented in our company."

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."

"The dashboard templates are limited."

"The vulnerability scan does not work correctly until the access privileges are set by the system administrator."

"If I want to have a very low-managed scan policy, it's a lot of work to create something which is very basic. If I use a tool like Nmap, all I have to do is download it, install it, type in the command, and it's good to go. In Security Center, I have to go through a lot of work to create a policy that's very basic."

"Tenable.sc's user interface could be improved."

"The integration is very good, although it still needs to improve."

"The tool's initial configuration is not so easy."

"The product should provide risk-based vulnerability management."

"For downloading reports, we have to go to the scan and then we have to go to the reports and download the Excel or CSV or PDF. I think these menus and clicks can be minimized."

More Tenable Security Center cons

"Sometimes even their support doesn't know why we're seeing certain issues."

"The only issue we’ve encountered is that sometimes the scans take a long time to complete."

"The speed of the scans takes some time, but in my opinion, it is not surprising for what it is doing."

"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."

"You need to be cautious about what it scans, as it could potentially cause issues."

"The reports are quite useless."

"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."

"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."

"I would rate the pricing a nine out of ten, where ten is expensive. It is the most expensive tool my company is using."

"Tenable.sc is more expensive than its competitors."

"We're able to save because we don't have to employ more staff members to help wit ht he scheduling of the scans, running the reports or sending them out to the systems owners. That alone is a big ROI for us."

"We're happy with the licensing cost and find it affordable."
