Featured Reviews

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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.
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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution is great for scanning servers."
"It gives you an unlimited IP scan."
"Tenable Nessus is cheap and flexible."
"Once you get past the initial implementation, the solution is very stable."
"My favorite part about Nessus is that you can customize the tool to scan exactly what you want. Microsoft releases new patches monthly on Patch Tuesday, and a lot of companies track that date. I set up Nessus for the day after Patch Tuesday to see which devices have already pushed those updates from Microsoft, so we can stay updated."
"The most valuable feature of Tenable Nessus is vulnerability detection."
"We looked at Tenable, Qualys and Rapid7. We found Tenable was the best of all three."
"I have found the vulnerability assessment and the reports to be useful."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"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 saw benefits from Zafran Security almost immediately after deploying it."
 

Cons

"The product must be more comprehensive."
"This is still a maturing product. Tenable is only a scanner for one ability, while other solutions like Rapid7 have more tools for verification. We still have to manually verify to see if the vulnerability is a false positive or not."
"The reports are okay, but the interface is a bit difficult to navigate in some cases."
"I think the reporting templates could be improved with Tenable Nessus."
"Tenable Nessus could improve reporting and information sharing. It would be helpful if we could share the reports and have a little bit better flexibility in the reporting of the data."
"The interface is a little bit clunky, and the reporting is not marvelous. There should be better integration of reporting between instances. Currently, the instance stands alone, and it produces a report. Being able to amalgamate those reports with another instance will be useful."
"They could make their reporting a little better."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"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."
 

Pricing and Cost Advice

"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly. The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job."
"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."
"We paid about six thousand dollars per license."
"I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price."
"In general, it is extremely expensive."
"There is an annual license required to use this solution."
