Able to discover unpatched servers, offers good stability, and scales very well
A low-cost service to evaluate the risk score of a supply chain would be very helpful. This could be useful for insurance companies offering cyber insurance to enterprise customers, providing the insurer with a valuable way to unobtrusively, quickly, and frequently assess their customers and apply appropriate premiums for the level of risk. This would also be useful for enterprises. They could, for example, assess companies prior to a merger or acquisition. What would also be useful for any enterprise would be if their supply chain has some kind of direct digital access to parts of their network.

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

Pros

"The solution is stable with 12 years of established historical data."
"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."
"Tenable Nessus is an absolutely stable and fantastic product."
"The features I personally like include host discovery."
"I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for."
"The solution provides time saving and cost saving benefits."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"Its initial setup was simple and straightforward."
"I have experience with it on my attack stations, and it's pretty good to optimize. Personally, I think Nessus is quite a good product."
 

Cons

"A low-cost service to evaluate the risk score of a supply chain would be very helpful."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"We feel the solution's technical support to be very bad."
"We'd like to see more integration potential within the solution."
"It would be nice for the professional module to include some of the reports available in the expert module."
"It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."
"The features are limited when it comes to scanning network devices for vulnerabilities."
"Tenable Nessus could improve the price."
"They should try to create an all-in-one solution."

"Tenable Nessus is affordable."
"The price of the solution is reasonable."

"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"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."
