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.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.
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."
"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."
"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."
"A valuable feature of the solution is that it is easy to understand."
"User friendly and good dashboards."
"The solution is easy to understand for users because instructions are included on the platform."
"The most valuable feature is the installation of Tenable which is incredibly easy."
"The solution is the most dynamic one I have seen thus far."
"Tenable Nessus streamlines the process of scanning for our organization."
"Scanners and reports using CIS templates ("de-facto" standard, easy to fix and to locate correction tips at documentation), tests against cloud providers, database profiles, several types of telecom devices, and others highly customizable scans."
"The vulnerability scanner is the most valuable feature."
"I rate the stability of the NodeZero Platform a ten out of ten."
"Penetration testing and scans are useful features."
"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."
"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."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
 

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."
"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 dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"The user interface of Tenable Nessus feels outdated and could be more user-friendly."
"EQA's and dashboards should be addressed in the next release."
"Remediation needs improvement."
"The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources."
"I would like to see more on the automation side."
"Model OS costs (and its segregation schema for individual modules)."
"Tenable Nessus is not feasible for a large company."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"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."
"You need to be cautious about what it scans, as it could potentially cause issues."
"The reports are quite useless."
 

Pricing and Cost Advice

Information not available
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"When comparing the price of Tenable Nessus to other similar solutions, such as Acunetix, Tenable Nessus is not as expensive. It is averagely priced in the market. We pay for the solution annually."
"The solution has free options."
"The newer tools are quite pricey. There is a case of some fine tuning that can be done in terms of licensing. The IP based licensing that is offered makes the tool very expensive. If they want the IT industry to adopt it, the price should be looked at."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."
"The cost is around $4,300 per year. Use is unlimited. You don't pay more if you want to use it for another IP."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
