Provides visibility and control over all APIs
I've built integrations for different systems, and some specific integrations might not be built in yet. This might be an issue for large customers but is not a major concern overall. So, the integration part could be a bit extended. Every organization has different systems, but Salt integrates with 90% of them. If a custom integration is needed, they can build it. They're very good at integrations. So, Salt Security can provide a proof of concept with system integration and share results within two weeks, which often leads to customer purchases. At this point, the product covers everything needed. They keep adding new features, and my local customers haven't requested any missing functionality. The product roadmap is good for the market.

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

"It's really great. I would rate the stability a nine out of ten. I haven't encountered any instability issues."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"Its initial setup was simple and straightforward."
"The most valuable feature of Tenable Nessus is the self-updating engine."
"You can then direct your team to create a report on the discovered vulnerabilities."
"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."
"It gives you an unlimited IP scan."
"Once you get past the initial implementation, the solution is very stable."
"The reports are pretty nice and easy to understand."
 

Cons

"The integration part could be a bit extended."
"Tenable Nessus could improve reporting and information sharing. It would be helpful if we could share the reports and have a little bit better flexibility in the reporting of the data."
"It would be a good idea if they have a simulation of attacks or a use case for finding a new vulnerability or dealing with a zero-day attack."
"This is still a maturing product. Tenable is only a scanner for one ability, while other solutions like Rapid7 have more tools for verification. We still have to manually verify to see if the vulnerability is a false positive or not."
"Nessus' reporting could be more user-friendly."
"The reporting is a bit cumbersome."
"Scans aren't done properly and some devices aren't pinged."
"Lacks some penetration testing-related services."
"It would be nice for the professional module to include some of the reports available in the expert module."
 

Pricing and Cost Advice

Information not available
"The solution is worth the cost. It's a good investment."
"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."
"Tenable Nessus is affordable."
"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."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"The solution is expensive."
"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."
"The product is free."
