Improved API visibility has revealed sensitive data exposures and supports faster remediation
Alert tuning can require some time depending on API volume. Some findings need internal validation before actioning. The collaboration flows between security and engineering teams could be expanded further. While the solution was straightforward to set up and gave me the visibility that I needed, it has to improve some details and features to achieve a perfect rating.

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

"Salt Security gave me much better visibility into API risk, helping me identify exposed endpoints, misconfigured APIs, and sensitive data flowing through APIs that required additional controls, and it has become an important part of my API security program."
"Salt Security gives you visibility of all your APIs, identifies API security issues, and immediately alerts you of attacks."
"It's really great. I would rate the stability a nine out of ten. I haven't encountered any instability issues."
"I can say that I am satisfied with Tenable Nessus' support and customer relations, which is why I'm still with the solution."
"Tenable Nessus has provided increased visibility across the organization's servers."
"It's scalable."
"Personally, I think Nessus is quite a good product."
"Out of the box, the product works well for us, so it's not a tool that we need to customize very much."
"The most valuable features of Tenable Nessus include its ease of access and quick usability."
"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."
"The predictive prioritization features are spot-on, and I enjoy how it actually gives me a prioritization that I can address and it associates it with a known vulnerability."
 

Cons

"The integration part could be a bit extended."
"The setup cost was acceptable, but adding additional APIs was actually quite expensive."
"The scalability of Tenable Nessus is good. However, it could be more flexible."
"We'd like to see the solution embrace more user-friendliness."
"The reporting is a bit cumbersome."
"There is room, overall, for improvement in the way it groups the workstations and the way it detects, when the vulnerability is scanned. Even when we would run a new scan, if it was an already existing vulnerability, it wouldn't put a new date on it."
"They should improve the I/O reporting and the customized spreadsheet export feature."
"I think the reporting templates could be improved with Tenable Nessus."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"They should try to create an all-in-one solution."

"The solution is worth the cost. It's a good investment."
