Behavioral AI has protected critical applications and now blocks complex external attacks
I think Salt Security could improve their implementations. The one that I saw was very complex and took quite a bit of time, and if the environment is unique at all, it takes quite a bit of time to figure out how to properly ensure that it will be implemented. A lot of times there is a steep learning curve for someone that hasn't been in it to figure out the APIs and really dig deep into it, but once you get used to it, it is easy. However, that ramp-up period could be tough. I think Salt Security could use a more enterprise focus. Some of the smaller companies that I have referred them to think it is a little bit too complex for them, so if they could come up with a different version or something a little bit easier to simplify their platform, they may be able to find more customers that way.

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 has positively impacted my organization and my client's organization by being able to stop cyberattacks and ensure that they have proper security over all their applications, giving them a sense of peace of mind that they have security over something that could ultimately take down the whole company if not mitigated properly."
"Salt Security gives you visibility of all your APIs, identifies API security issues, and immediately alerts you of attacks."
"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."
"It's really great. I would rate the stability a nine out of ten. I haven't encountered any instability issues."
"What I like most about Tenable Nessus is its vulnerability scanning feature."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
"Using Nessus, we are able to scan and locate any potential vulnerabilities that our clients may have and point them out to them."
"It notifies us of vulnerabilities as they arise, allowing us to respond quickly without manual intervention."
"Nessus has greatly improved the security of our clients' networks."
"A valuable feature of the solution is that it is easy to understand."
"It gives you an unlimited IP scan."
"The features I personally like include host discovery."
 

Cons

"Regarding scalability, for users in smaller environments, it is not exactly the best."
"The setup cost was acceptable, but adding additional APIs was actually quite expensive."
"The integration part could be a bit extended."
"In terms of what could be improved, I would say its reporting portion."
"Nessus' reporting could be more user-friendly."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"One significant drawback we encounter is the tool's tendency to flag patched packages incorrectly. For instance, if a package is patched by Debian maintainers but not updated to a major or minor version, Nessus may still flag it as vulnerable based on its database. This discrepancy leads to false alarms and requires our developers, system admins, and DevOps teams to address them."
"I would like to see an improvement in the ranking of high, medium and low vulnerability."
"We use credentialed scans. They need more permissions and more changes or settings on Windows and Linux."
"Sometimes, the categorization for clients was tricky at first, however, they eventually got used to it."
"Unfortunately, the solution consumes more system resources when it's being run and I'd like that to be reduced."
 

Pricing and Cost Advice

Information not available
"I would like to see better discounts."
"Our organization is huge so our license costs $30,000."
"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
"The newer tools are quite pricey. There is a case of some fine tuning that can be done in terms of licensing. The IP based licensing that is offered makes the tool very expensive. If they want the IT industry to adopt it, the price should be looked at."
"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."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"Tenable Nessus is affordable."
"The price of Tenable Nessus is too expensive for each service center."
