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.

I would not personally speak to what I like about Tenable Nessus, because I think the only reason many customers are using it is because it is well-known and they have received directives from their companies or mother companies. For me, the key value is the ease of use and integration with SIEMs because it has built-in integrations with IBM QRadar and others. Tenable Nessus is typically a widely integrated tool within the existing security ecosystem. It is part of the security policy that customers have implemented, so it does provide positive impact and is beneficial to use Tenable Nessus.

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."
"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."
"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 vulnerability scanner is the most valuable feature."
"With my experience, I would definitely recommend it."
"The reports are pretty nice and easy to understand."
"Security is complicated a subject. There's a lot involved in Tenable Nessus, but the solution is easy to run and manage and we have had a lot of good success with it."
"It gives you an unlimited IP scan, is a cheap solution compared to Rapid7 or Qualys, and is very user-friendly so customers can easily scan their network."
"It's scalable."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"It is easy to deploy and easy to use. Its reporting is good. From this reporting, you can see the pain point in your network, which makes it easy to fix them. It is easy to understand the reports and export them."
 

Cons

"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 integration part could be a bit extended."
"Offer a more flexible strategic and high-level dashboards based on previous comments (minus technical and more business-oriented)."
"Tenable Nessus is very costly compared to OpenVAS and sits on the higher side."
"To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."
"We'd like to see the solution embrace more user-friendliness."
"The support from Tenable Nessus is okay. However, they are sometimes slow and can take days to respond."
"Tenable Nessus could improve the reporting."
"Tenable Nessus is not feasible for a large company."
"Pricing is one of the most important features, and it is something that they can improve on."
