Helps us complete testing more quickly by eliminating many unwanted test cases

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, and from that we can generate automated test cases, but what happens on the target device, what is the reason for the crash, for that we have to do manual debugging. They do not have diagnostic tools for the target side. Rather, they have them but they are very minimal and not very helpful. They can improve a lot on that.

Quotes from Members

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

Pros

"The solution is highly stable."

"It comes equipped with an internal applicator, which automatically identifies and addresses vulnerabilities within the program."

"It generates automated reports."

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

"I find it to be one of the most comprehensive tools, with support for manual intervention."

"The product is really easy to use."

"The most valuable feature of the solution is the speed at which it can scan multiple domains in just a few hours."

"Picks up weaknesses in our app setups."

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."

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

"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."

Cons

"When monitoring the traffic we always have issues with the bandwidth consumption and the throttling of traffic."

"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."

"The cost can be reduced as management has noted it to be on the higher side."

"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."

"I rate its stability six out of ten."

"Integration into other tools is very limited for Acunetix. While we're trying to incorporate a CI/CD process where we're integrating with JIRA and we're integrating with Jenkins and Chef, it becomes problematic. Other tools give you a high integration capability to connect into different solutions that you may already have, like JIRA."

"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."

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

More Acunetix cons

"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."

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

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."

"All things considered, I think it has a good price/value ratio."

"Acunetix was around the same price as all the other vendors we looked at, nothing special."

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

"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."

"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 price is exceptionally high."
