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.

Context-aware code analysis has reduced noise and now improves developer experience with actionable security findings

I have consistently observed that their scan time is an issue for mono repos. Sometimes with their AI-based scanning, when you triage that scan, the scan never completes or finishes(, which makes it difficult. Another consistent issue is that whenever you have a new repo to onboard to the platform, the tool ideally should detect the master branch by default. However, sometimes the tool fails to identify it and will never scan it unless manually somebody looks into it and fixes the issue. Although their support team is really good, this issue was present six or eight months ago during the POC and is still present now. If it is affecting multiple customers, it should be prioritized and fixed. I would say that their integration aspects could have been improved. I see a lot of different security solutions that provide flexibility to the security teams based on Jira project, team divisions, Slack, and all those can be very much easily customized. Semgrep needs to work on the enhancement of their notification capabilities. Currently, they are working on identifying business logic vulnerabilities or privilege escalation vulnerabilities by looking at the code, and they should continue to focus on and improve this effort. Regarding stability, whenever you have a mono-repo which is a very large repository, the scan never finishes or the scan never kicks in. At that time, you have to reach out to the support team and ask them to expand the resources in the back end to fix it. This is an issue I keep seeing often on that platform.

Quotes from Members

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

Pros

"The HUD, Heads Up Display, is a good feature; it provides on-site testing and saves a lot of time."

"It has improved my organization with faster security tests."

"The scalability of this product is very good."

"We use OWASP Zap for web application security scanning."

"The valuable features are that it's very simple to use and the user interface is very good, particularly for beginners so they can start the application easily."

"It scans while you navigate, then you can save the requests performed and work with them later."

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

"Technical support is excellent."

More OWASP Zap pros

"Compared to other competitors in the market, the AI-backed capability is the biggest strength of Semgrep."

"The best part of Semgrep is its ease of integration with CI/CD pipelines and how it is a developer-friendly tool."

"Semgrep flourishes with the SAST, secret scanning, and Software Composition Analysis types of scanning."

"Since implementing Semgrep, I have noticed significant outcomes, for example, I can resolve vulnerabilities that previously took four days in under a day, saving both time and money, thus enhancing our return on investment."

"The feature is easy to use, saves a lot of time, and is streamlined in nature."

"The most valuable feature is the ability to write our custom rules."

Cons

"The product should allow users to customize the report based on their needs."

"When comparing OWASP Zap and Burp Suite, the main difference besides pricing is that OWASP Zap has limitations with reporting levels and UI, which affects its reporting capabilities, whereas Burp Suite is already advancing with new AI features and scanning capabilities that OWASP Zap seems to be lacking."

"It would be beneficial to enhance the algorithm to provide better summaries of automatic scanning results."

"It would be ideal if I could try some pre-built deployment scenarios so that I don't have to worry about whether the configuration sector team is doing it right or wrong. That would be very helpful."

"It's possibly just a limitation of the product itself but sometimes it won't scan a particular website so you have to manually go in and make some configuration changes."

"It needs more robust reporting tools that can be in an editable form."

"The reporting feature could be more descriptive."

"OWASP should work on reducing false positives by using AI and ML algorithms. They should expand their capabilities for broader coverage of business logic flaws and complex issues."

More OWASP Zap cons

"I give Semgrep a six out of 10 simply because there are other tools that are better than this out there."

"I have consistently observed that their scan time is an issue; sometimes with their AI-based scanning, when you triage that scan, the scan never completes or finishes, which makes it difficult."

"Semgrep can be improved by making it more user-friendly."

"There should be more information on how to acquire the system, catering to beginners in application security, to make it more user-friendly."

"However, as a tool it is really complex to maintain and to use, and it has a huge price tag."

Pricing and Cost Advice

"The tool is open source."

"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."

"This app is completely free and open source. So there is no question about any pricing."

"OWASP Zap is free to use."

"The solution’s pricing is high."

"It is open source, and we can scan freely."

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

"The tool is open-source."
