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.

AI-driven analyses improve efficiency and reliability
I find all the features of PortSwigger Burp Suite Professional most useful, particularly the AI enhancement for results and follow-up for retests. This feature helps me follow up on my results and perform retests step-by-step. The automation in AI verifies the findings, ensuring they are correct, and performs step-by-step testing. The Intruder tool enhances testing efficiency through intercepting information and analyzing it. It helps to analyze web applications and intercept the traffic.

Quotes from Members

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

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."
"The solution is stable."
"I have found this solution has more plugins than other competitors which is a benefit. You are able to attach different plugins to the security scan to add features. For example, you can check to see if there are any payment systems that exist on a server, or username and password brute force analysis."
"The suite testing models are very good. It's very secure."
"The way they do the research and they keep their profile up to date is great. They identify vulnerabilities and update them immediately."
"I find the attack model quite amazing, where I can write my scripts and load my scripts as well, which helps quite a bit. All the active scanning that it can do is also quite a lot helpful. It speeds up our vulnerability assessment and penetration testing. Right now, I am enjoying its in-browser, which also helps quite a bit. I'm always confused about setting up some proxy, but it really is the big solution we all want."
"The most valuable feature of PortSwigger Burp Suite Professional is the advanced features, user-friendly interface, and integration with other tools."
"This solution has helped a lot in finding bugs and vulnerabilities, and the scanner is good enough for simple web apps."
"The tool provides complimentary services. It allows you to add a lot of extensions, and you can get extensions quite often. It is quite a flexible application."
 

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."
"The biggest drawback is reporting. It's not so good. I can download them, but they're not so informative."
"The initial setup is a bit complex."
"It should provide a better way to integrate with Jenkins so that DAST (dynamic application security testing) can be automated."
"The use of system memory is an area that can be improved because it uses a lot."
"The technical support team's response time is mostly delayed and should be improved."
"Improvement should be done as per the requirements of customers."
"Mitigating the issues and low confluence issues needs some improvement. Implementing demand with the ChatGPT under the web solution is an additional feature I would like to see in the next release."
"The Auto Scanning features should be updated more frequently and should include the latest attack vectors."
 

Pricing and Cost Advice

"Licensing is a bit expensive."
"I rate the pricing a four out of ten."
"It is a cheap solution, but it may not be cheaper than other solutions."
"Our licensing cost is approximately $400 USD per year."
"Licensing costs are about $450/year for one use. For larger organizations, they're able to test against multiple applications while simultaneously others might have multiple versions of applications which needs to be tested which is why we have the enterprise edition."
"PortSwigger is a bit expensive."
"The cost is approximately $500 for a single license, and there are no additional costs beyond the standard licensing fees."
"The pricing of the solution is reasonable. We only need to pay for the annual subscription. I rate the pricing five out of ten."
"There are multiple versions available of PortSwigger Burp Suite, such as enterprise, commercial, professional, and beginners."
