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

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."
"It's really great. I would rate the stability a nine out of ten. I haven't encountered any instability issues."
"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."
"Nessus has greatly improved the security of our clients' networks."
"I have chosen Nessus because it's very simple to use and install."
"I would definitely recommend this solution; it's the best that I've used so far."
"I like this solution because it is complete, it can scan and check many types of vulnerabilities, it can also check for compliance, it fits very well in my environment, it is very easy to use, and there is a very good cost-benefit of this solution."
"Among the most valuable features are scanning for vulnerabilities and the reporting. The reporting templates are okay. I like that I can see all the hosts with different vulnerabilities."
"The features I personally like include host discovery."
"The solution is easy to understand for users because instructions are included on the platform."
"The most valuable feature of Tenable Nessus is website scanning."
 

Cons

"The integration part could be a bit extended."
"The setup cost was acceptable, but adding additional APIs was actually quite expensive."
"Regarding scalability, for users in smaller environments, it is not exactly the best."
"The interface is a little bit clunky, and the reporting is not marvelous. There should be better integration of reporting between instances. Currently, the instance stands alone, and it produces a report. Being able to amalgamate those reports with another instance will be useful."
"They could make their reporting a little better."
"My only concern is related to its pricing."
"Unfortunately, the solution consumes more system resources when it's being run and I'd like that to be reduced."
"The reporting is a bit cumbersome."
"There should be a possibility to install agents on scanned machines. Tenable IO provides the capability of using local agents to check local problems, but this feature is not there in Tenable Nessus Professional. It would be nice to have something similar in Tenable Nessus Professional. We should have the capability to use local agents installed on the machines to locally check a problem."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"The report for counters is too simple and would be improved by a dashboard."
 

Pricing and Cost Advice

Information not available
"We paid about six thousand dollars per license."
"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
"This solution is affordable."
"It has a fair cost and very good cost-benefit ratio."
"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."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"There is an annual license required to use this solution."
"The price of Tenable Nessus could improve, it is expensive."
