CEO at Xcelliti

Has enabled teams to improve security testing with smooth integration and high accuracy

Acunetix has a very good ratio of fewer false positives, so users don't need to retest everything. Acunetix operates smoothly with no interruptions required, and it performs at 100% efficiency without issues in scanning anything. The solution is excellent at detecting SQL injection and cross-site scripting vulnerabilities. Acunetix integrates with every type of tool, including CI/CD tools, offering 100% integration in DevOps environments. The main benefit of Acunetix is that at the first level, users can address security issues related to penetration testing, allowing them to expose vulnerabilities and ensure all required testing is completed with very few false positives.

Product security tests for switches and router sections

Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install. What I see in the documentation isn't that. Even if something doesn't malfunction, sometimes it is hard to install and execute. The product needs video documentation. This would help a lot more.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The features of Acunetix have proved most effective in identifying vulnerabilities."

"It can operate both as a standalone and it can be integrated with other applications, which makes it a very versatile solution to have."

"The solution is excellent at detecting SQL injection and cross-site scripting vulnerabilities."

"The product is really easy to use."

"The scalability is good. The scalability is more than good because it can operate both as a standalone and it can be integrated as part of applications. So that really makes it a very, very versatile solution to have."

"It's very user-friendly for the testing teams. It's very easy for them to understand things and to fix vulnerabilities."

"The tool's most valuable feature is performance."

"I haven't seen reporting of that level in any other tool."

More Acunetix pros

"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."

"Whatever the test suit they give, it is intelligent. It will understand the protocol and it will generate the test cases based on the protocol: protocol, message sequence, protocol, message structure... Because of that, we can eliminate a lot of unwanted test cases, so we can execute the tests and complete them very quickly."

"We have found multiple issues in our embedded system network protocols, related to buffer overflow. We have reduced some of these issues."

Cons

"The jargon used makes it difficult for project managers to understand the issues, and the technical explanations used make it difficult for developers to understand issues. These things should be simplified much more. That would be very helpful for us when explaining to them what needs to be fixed. The report output needs to be simplified."

"Acunetix should improve by further reducing false positives and providing more customized reports, plus better integration with newer tools such as GitHub and Azure DevOps."

"It would be nice to have a feature to "retest" only a single vulnerability that the customer reports as patched, and delete it from the next scans since it has already been patched."

"There's a clear need for a reduction in pricing to make the service more accessible."

"There was an issue related to updates from the internet."

"I rate its stability six out of ten."

"You can't actually change your password after you've set it unless you go back into the administration account and you change it there. Thus, if you're locked out and don't remember your password, that's a thing."

"There is room for improvement in the pricing."

More Acunetix cons

"Codenomicon Defensics should be more advanced for the testing sector. It should be somewhat easy and flexible to install."

"Sometimes, when we are testing embedded devices, when we trigger the test cases, the target will crash immediately. It is very difficult for us to identify the root cause of the crash because they do not provide sophisticated tools on the target side. They cover only the client-side application... They do not have diagnostic tools for the target side. Rather, they have them but they are very minimal and not very helpful."

"It does not support the complete protocol stack. There are some IoT protocols that are not supported and new protocols that are not supported."

Pricing and Cost Advice

"The pricing and licensing are reasonable to a point. In order to run multiple scans at a time, we are going to have to purchase a 100 count license, which is an overkill. Though, compared to what we were paying for, the cost seems reasonable."

"The pricing is a little high, and moreover, it's kind of domain-based."

"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."

"The solution is expensive."

"The price is exceptionally high."

"The costs aren't very expensive. It costs around $3000 or $4000."

"When compared with other products, the pricing is a little bit high. But it gives value for the price. It serves the purpose and is worthwhile for the price we pay."

"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."
