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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"Nessus gives me a good preview of vulnerabilities and good suggestions for remediation. It's easy to find a description of a given vulnerability and solutions for it."
"The most valuable feature of Tenable Nessus is vulnerability detection."
"The plug-in text information is quite useful."
"Out of the box, the product works well for us, so it's not a tool that we need to customize very much."
"The automatic scanner and scheduler are pretty cool."
"A valuable feature of the solution is that it is easy to understand."
"The solution is great for scanning servers."
"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 are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran is an excellent tool."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
 

Cons

"From my point of view the solution basically is not for the big enterprise."
"The reporting could be improved. The reporting in Rapid7 is much better."
"The inventory management function in this solution needs improvement."
"The solution should be able to support more devices."
"Nessus' reporting could be more user-friendly."
"The product could have unique features similar to one of its competitors."
"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."
"It would be nice for the professional module to include some of the reports available in the expert module."
"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."
 

Pricing and Cost Advice

"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
"This solution is affordable."
"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
"In general, it is extremely expensive."
"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."
"The is a free version of Tenable Nessus available."
"Tenable Nessus is affordable."
