Featured Reviews

KashifJamil - PeerSpot reviewer
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.

SK
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 most valuable feature of the solution is the speed at which it can scan multiple domains in just a few hours."
"I haven't seen reporting of that level in any other tool."
"We are able to create a report which shows the PCI DSS scoring and share it with the application teams. Then, they can correlate and see exactly what they need to fix, and why."
"The most important feature is that it's a web-based graphical user interface. That is a great addition. Also, the ability to schedule scans is great."
"We use the solution for the scanning of vulnerabilities like SQL injections."
"Picks up weaknesses in our app setups."
"It generates automated reports."
"The most valuable feature of Acunetix is the UI and the scan results are simple."
More Acunetix pros
"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."
"The product is related to US usage with TLS contact fees, i.e. how more data center connections will help lower networking costs."
 

Cons

"We have had issues during upgrades where their scans worked on some apps better with previous versions. Then, we had to work with their tech support, who were great, to get it fixed for the next version."
"In terms of what needs improvement, the way the licensing model is currently is not very convenient for us because initially, when we bought it, the licensing model was very flexible, but now it restricts us."
"There's a clear need for a reduction in pricing to make the service more accessible."
"There is room for improvement in the pricing."
"Tools that would allow us to work more efficiently with the mobile environment, with Android and iOS."
"The solution can be improved by adding the ability to scan subdomains automatically, and by providing reports that can be exported to external databases to share with other solutions."
"There are some versions of the solution that are not as stable as others."
"Acunetix needs to include agent analysis."
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

"When we looked at all other vendors and what they were asking for, to provide a third of what Acunetix was capable of doing, it was an easy decision... But now that it's coming to a cost where it's line with market value, it becomes more of a competition... Acunetix is raising the cost of licensing. It's 3.5 times what we were initially quoted."
"It is a bit expensive. If you need to check five applications, you have to pay almost 14,000. It is an agreement for two years at 7,000 per year for only five applications. You cannot change the applications in the license. So, you are stuck with the same license for the five applications for one full year."
"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."
"All things considered, I think it has a good price/value ratio."
"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 pricing is a little high, and moreover, it's kind of domain-based."
"The price is exceptionally high."
"The solution is expensive."
