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.
MohammedJaffir - PeerSpot reviewer

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."
"It's scalable."
"The stability is very good."
"The best features of Tenable Nessus include its compatibility with other applications such as SIEM and other apps, allowing Tenable Nessus to work smoothly with them."
"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."
"The product's most valuable features are vulnerability and asset management. It can define the rules and validate the configuration."
"The solution is great for scanning servers."
"It does exactly what you expect it to do, and its pricing is great. We couldn't really ask for a better deal."
"The most valuable features are that it's fast, it's easy to use and it provides good reports."
 

Cons

"The reports must be more specific to help us understand what we should do to mitigate the problem."
"I think the reporting templates could be improved with Tenable Nessus."
"Tenable Nessus could include a broader range of IT assets."
"The solution could improve by having better integration with different vendors' IPS solutions. The ACLs and IPS policies signatures should be enabled based on the results of Tenable Nessus automatically, we currently have to do it manually which is very time-consuming. It has done a good job integrating with Fortinet but we would like it to be better integrated with other solutions that we have."
"Consumes more system resources when it's running."
"Multiple steps to create an actionable plan will be a great addition to Nessus."
"I have found it is sometimes difficult to control the Zoom meeting sessions. For example, it is difficult to know who is talking and when trying to mute everyone but the speaker you end up muting everyone. When using multiple screens it is laborious to find the control buttons, such as to start a session. Additionally, when a recording is done I have found it difficult to find them, there should be an easier way to retrieve them."
"Tenable Nessus could improve the price."
"The solution could improve security updates."
 

Pricing and Cost Advice

"The product is free."
"Tenable Nessus is affordable."
"The is a free version of Tenable Nessus available."
"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."
"The price of the solution is reasonable."
"The price is reasonable."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"There is an annual license required to use this solution."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
