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

"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."
"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 vulnerability scanner is the most valuable feature."
"If you are implementing it as part of an ongoing VA or retention operation, you should probably use Tenable."
"Nessus has greatly improved the security of our clients' networks."
"What I like about it is the fact that it can figure out what changes we need to make on our systems to ensure that they're hardened properly."
"It is a very easy tool to use."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
"Easy to set up vulnerability scanner with good stability and a responsive technical support team."
"The valuable feature for me is being able to ping the computers to do the automated scan and to come back and be able to see everything."
 

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."
"We'd like to see the solution embrace more user-friendliness."
"Nessus' reporting could be more user-friendly."
"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."
"Tenable Nessus could improve the reporting."
"It would be nice for the professional module to include some of the reports available in the expert module."
"In general, it is extremely expensive. If they have a higher price, that's fine, but if there were one or two solutions where you can buy something for a cheaper price then that would make sense for many users."
"We find that some devices aren't pinged and the scans aren't done properly."
"I would like to see more on the automation side. There should be proper tools and support for automation in Tenable itself."
 

Pricing and Cost Advice

Information not available
"The price of the solution is reasonable."
"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."
"Cost-wise, it's an affordable tool."
"The price of Tenable Nessus could improve, it is expensive."
"We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
"The price is reasonable."
"Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly. The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job."
"It has a fair cost and very good cost-benefit ratio."
