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 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."
"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."
"The scanning capabilities are most valuable when compared to Nessus."
"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 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."
"The most valuable features of Tenable Nessus include its ease of access and quick usability."
"It gives a holistic view of your entire environment."
"The value that Tenable Nessus brings to my company is significant because we can see risks; it is also good to see the pages risk and system risks, and it saves money."
"Tenable Nessus is cheap and flexible."
"It does exactly what you expect it to do, and its pricing is great. We couldn't really ask for a better deal."
 

Cons

"The setup cost was acceptable, but adding additional APIs was actually quite expensive."
"The integration part could be a bit extended."
"Regarding scalability, for users in smaller environments, it is not exactly the best."
"The integration part is not good because five years ago, Tenable Nessus had more integration capability. After that, Tenable changed their policies and strategy."
"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."
"The report for counters is too simple and would be improved by a dashboard."
"Tenable Nessus could improve by having more steady updates which will reduce the vulnerabilities."
"We find that some devices aren't pinged and the scans aren't done properly."
"It wasn't very clear how the scripts are running the scans. There's information about the script but it's not straightforward. The script information for each of the plugins should be available, but it doesn't give us straightforward direct information about how it was executed. That needs to be more clear."
"We feel the solution's technical support to be very bad."
"The professional version is not very scalable. It's not really scalable considering the number of assets and clients that I have."
