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.

Worthwhile from the regulatory requirements and analytics perspective, but is expensive and not easy to use
We are a full security base integration and application business. We help with implementation and deployments. I used Guardium to help with a cloud migration to check and do some validation for a client's data landscape and services so that they made sure that they were all secure in overall…
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.

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."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Zafran is an excellent tool."
"The reporting features are good and there are many built-in reports that can be quickly configured."
"The most valuable feature is that it provides a simple English recommendation on actions that you need to take once a vulnerability is discovered."
"It helped with some of the regulatory requirements. It also helped with some of the security analytics and analysis. It was worthwhile from that perspective."
"Among the most valuable features are scanning for vulnerabilities and the reporting. The reporting templates are okay. I like that I can see all the hosts with different vulnerabilities."
"I like the fact that it was not expensive. I like that it's user-friendly."
"The initial setup of Tenable Nessus is very easy."
"Tenable Nessus is an absolutely stable and fantastic product."
"The most valuable features of Tenable Nessus include its ease of access and quick usability."
"Easy to set up vulnerability scanner with good stability and a responsive technical support team."
"Nessus is effortless to integrate."
"We have around 500 virtual machines. Therefore, we conduct monthly scans and open tickets for our developers to address identified vulnerabilities. These scans cover the servers, other network equipment, and appliances in our infrastructure."
 

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."
"Building policies is not that easy. There are some things that are turned off by default, for example, displaying values."
"It was not as easy to use. The user-friendliness of it was somewhat lower than what I was expecting. It was also lacking in terms of the ease of the setup. There should be an automatic agent for deployment."
"The interface could be improved by having sub-groups of tests, ultimately making the process of collecting tests faster."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"The user interface of Tenable Nessus feels outdated and could be more user-friendly."
"Sometimes, the categorization for clients was tricky at first, however, they eventually got used to it."
"They should improve the I/O reporting and the customized spreadsheet export feature."
"The price could be reduced."
"Multiple steps to create an actionable plan will be a great addition to Nessus."
"In terms of what could be improved, I would say its reporting portion."
"Tenable Nessus could improve by having more steady updates which will reduce the vulnerabilities."
 

Pricing and Cost Advice

Information not available
"One thing not advantageous for it was that it was a little bit more expensive. I would rate it one out of five in terms of pricing."
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
"The solution has a single price for unlimited assets."
"Tenable Nessus is affordable."
"The solution is expensive."
"The product is free."
"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."
"Our organization is huge so our license costs $30,000."
"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
