Featured Reviews

César Ibáñez - PeerSpot reviewer
Corporate support at ISS S.A.
A highly scalable and easy-to-use solution that helps identify vulnerabilities
The time taken for a scan is too long. I tried to scan a website, and it took me ten hours. The report was sent to me two days later. The reports must be more specific to help us understand what we should do to mitigate the problem. There is not a lot of documentation on how to manage all the features of the product.

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

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 very easy to use."
"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."
"Tenable Nessus is one of the best vulnerability assessment tools, that I know."
"The most valuable feature of Tenable Nessus is website scanning."
"The ease of use is the primary valuable feature. This specific version is very straightforward. I like the ability to modify it and configure it based on the different policies."
"The initial setup is very straightforward."
"We looked at Tenable, Qualys and Rapid7. We found Tenable was the best of all three."
"The solution is very stable."
"Tenable Nessus is cheap and flexible."
 

Cons

"The reports must be more specific to help us understand what we should do to mitigate the problem."
"I would like to see more on the automation side."
"The inventory management function in this solution needs improvement."
"The solution should be able to support more devices."
"Model OS costs (and its segregation schema for individual modules)."
"Technically, it is an excellent and the best solution available in Libya. My only concern is related to its pricing. They are an emerging company in Libya, and they need to put in some effort to provide us with very good prices so that customers can go with the best solution. Chinese companies are getting into the market here, and they're providing very cheap solutions."
"EQA's and dashboards should be addressed in the next release."
"Remediation needs improvement."
"Consumes more system resources when it's running."
 

Pricing and Cost Advice

"The product is free."
"We pay approximately $2,500 on a yearly basis."
"The price of Tenable Nessus is too expensive for each service center."
"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."
"The price of the solution is reasonable."
"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."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"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 price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
