Features: Spirent CyberFlood offers comprehensive traffic generation, testing compliance, and flexible scheduling, ideal for diverse attack simulations. OWASP Zap provides robust web application scanning, automation options like automated scanning and crawling, and extensive vulnerability detection, ensuring simplified web security management.

Room for Improvement: Spirent CyberFlood could enhance ease of use and setup complexity, as its structured deployment is resource-intensive.

Project Manager at Al Hassan LLC

Simplifies vulnerability discovery and has high quality support

There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores. Sometimes, a vulnerability initially categorized as high severity may be reduced to medium or low over time after security patches are applied. This alignment with the present severity score and CVSS score could be improved.

Test assurance improves compliance and products with good performance

The user interface could be improved to facilitate easier navigation. The most significant issue I encounter with the solution is the user interface. It would be beneficial if I could remain on one screen most of the time. Even if the system navigates me to another screen, it should effectively return me to the main screen.

Quotes from Members

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

Pros

"The solution enables a person to add the certificate and check the queries, to see if there are any that are undefined, so a person can have a list of the types of queries and can trace them."

"If you're a company and you've got your own websites, internally and externally, it's great."

"Technical support is excellent."

"I consider OWASP Zap to be the most effective solution overall; being open source allows integration with other systems via OWASP Zap APIs."

"The best feature is the Zap HUD (Heads Up Display) because the customers can use the website normally. If we scan websites with automatic scanning, and the website has a web application firewall, it's very difficult."

"ZAP is easy to use. The automated scan is a powerful feature. You can simulate attacks with various parameters. ZAP integrates well with SonarQube."

"The product discovers more vulnerabilities compared to other tools."

"OWASP Zap is straightforward to use. If someone doesn't have the budget for tools like Burp Suite, OWASP Zap is an excellent alternative."

More OWASP Zap pros

"CyberFlood's best features are its user-friendliness and scheduling function."

"The testing compliance feature is particularly impressive."

"The feature I find most valuable is the traffic generator."

"Our customers use it to check for unauthorized file transfer."

"CyberFlood is bundled and basic, but it's still powerful and easy to use, and I would recommend it, especially for beginners."

"If any customer doubts their existing network security policy this is a perfect product to analyze their network security and even existing processes."

"CyberFlood is flexible."

Cons

"We have had stability issues a few times."

"The work that it does in the limited scope is good, but the scope is very limited in terms of the scanning features. The number of things it tests or finds is limited. They need to make it a more of a mainstream tool that people can use, and they can even think about having it on a proprietary basis. They need to increase the coverage of the scan and the results that it finds. That has always been Zap's limitation. Zap is a very good tool for a beginner, but once you start moving up the ladder where you want further details and you want your scan to show more in-depth results, Zap falls short because its coverage falls short. It does not have the capacity to do more."

"Too many false positives; test reports could be improved."

"There's very little documentation that comes with OWASP Zap."

"The solution is somewhat unreliable because after we get the finding, we have to manually verify each of its findings to see whether it's a false positive or a true finding, and it takes time."

"It would be a great improvement if they could include a marketplace to add extra features to the tool."

"While the solution can scale to a certain extent, it cannot scale a lot."

"Right now, I can't give it off to a team and expect them to give me a report that I'm happy with."

More OWASP Zap cons

"CyberFlood's accessibility and support for multiple browsers could be better."

"The user interface could be improved to facilitate easier navigation."

"The initial setup is not straightforward and can be quite challenging."

"The solution needs more ports, more speed, and more gigabytes."

"Sometimes, when you configure parameters the hardware can't run, it will get stuck at those points without telling you what happened. It would be helpful if the error reporting provided more details about why the test setting is not running. It would be nice if there were a space in the hardware module for you to add some external hardware for more rigorous testing."

"I would also like to see updates on a more frequent schedule."

Pricing and Cost Advice

"The tool is open source."

"OWASP Zap is free to use."

"We have used the freeware version. I believe Zap only has freeware."

"It's free. It's good for us because we don't know what the extent of our use will be yet. It's good to start with something free and easy to use."

"The solution’s pricing is high."

"It is highly recommended as it is an open source tool."

"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."

"It's free and open, currently under the Apache 2 license. If ZAP does what you need it to do, selling a free solution is a very easy."
