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

"We use the solution for the scanning of vulnerabilities like SQL injections."

"For us, the most valuable aspect of the solution is the log-sequence feature."

"The product is really easy to use."

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

"Overall, it's a very good tool and a very good engine."

"One of the features that I feel is groundbreaking, that I would like to see expanded on, is the IAS feature: The Interactive Application Security Testing module that gets loaded onto an application on a server, for more in-depth, granular findings. I think that is really neat. I haven't seen a lot of competitors doing that."

"Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick."

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

More Acunetix pros

"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."

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

Cons

"Acunetix needs to be dynamic with JavaScript code, unlike Netsparker which can scan complex agents."

"Currently only supports web scanning."

"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."

"The solution's pricing could be better."

"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."

"I had some issues with the JSON parameters where it found some strange vulnerabilities, but it didn't alert the person using it or me about these vulnerabilities, e.g., an error for SQL injection."

"Tools that would allow us to work more efficiently with the mobile environment, with Android and iOS."

"The pricing is a bit on the higher side."

More Acunetix cons

"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."

"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."

Pricing and Cost Advice

"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 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."

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

"The solution is expensive."

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

"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."
