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.

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 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 gives you visibility of all your APIs, identifies API security issues, and immediately alerts you of attacks."
"To me, that was a better selling point because it was real: it wasn't demo data, it was our own network showing, "Hey, we're vulnerable because of this, and here's the tool that did it," which got us the buy-in we needed from upper management."
"Quick assessments, compliance scores, and results are provided without having to do agents."
"The support has been really cooperative."
"The trial version is very good for testing whether it will suit your needs."
"Tenable is the best vulnerability management product in the world, and I recommend it."
"The solution is worth the cost; it's a good investment."
"Overall Zoom is a good solution."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
 

Cons

"The integration part could be a bit extended."
"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."
"In terms of what could be improved, I would say that the reporting feature needs to be improved."
"We use credentialed scans. They need more permissions and more changes or settings on Windows and Linux."
"They need more flexible pricing."
"We'd like to see more integration potential within the solution."
"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."
"The solution should be able to support more devices."
"The product must be more comprehensive."
"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time. Tenable.io has more detailed reports. Having a better dashboard that can show where the vulnerabilities are and be categorized would be helpful. We then could present them to upper management for a deep overview of our network posture which they do not see."
 

Pricing and Cost Advice

Information not available
"The product pricing is dynamic and varies based on the specific needs of each project and customer."
"The is a free version of Tenable Nessus available."
"The price of the solution is reasonable."
"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."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."
"This solution is affordable."
"Cost-wise, it's an affordable tool."
