10 Best OWASP ZAP Alternatives And Competitors

Read this review and comparison of the top OWASP ZAP Alternatives with features, ratings, and pricing to select the best OWASP ZAP Competitor:

As far as Open-Source security testing solutions go, there aren’t many that share the popularity that OWASP ZAP enjoys. OWASP ZAP, also known as Zed Attack Proxy, is an open-source penetration testing tool that is currently being maintained by the Open Web Application Security Project.

It is a flexible and extensible solution exclusively designed to assess web applications for vulnerabilities.

The platform features a good interface and is simple to use. It facilitates automatic scanning and generates reports that become ultimately useful in patching identified vulnerabilities. The solution is also highly scalable. Being free to use is perhaps what makes it more appealing to businesses or developers who can’t afford other rather expensive alternatives.

OWASP ZAP Alternatives Review

OWASP ZAP alternatives

However, the tool isn’t infallible. In fact, it is severely lacking in features that security teams expect from their vulnerability management platforms today. It also doesn’t fare well when identifying false positives. Fortunately, OWASP ZAP isn’t the only solution out there that can guarantee excellent application security.

In this article, we will look at tools that offer near-perfect vulnerability management solutions to their users. Based on popular customer receptions and our own experience with each of them, we will introduce you to the best OWASP Zap Alternatives the market offers today.


  • Although OWASP ZAP features a good user interface, it’s difficult to deploy. So look for tools that are easy to deploy, use, and possess a decent UI.
  • A centralized visual dashboard that presents you with insights and analytics about your scan activity detected assets, and vulnerabilities is a must.
  • The platform should be capable of generating detailed technical and compliance reports that are easy to read.
  • A low number of ‘false positives’ is necessary, so security teams are only focused on patching confirmed vulnerabilities.
  • Look for vendors that offer 24/7 customer support.
  • Price is important. Look for vendors that offer flexible, affordable pricing plans that fall under your budget.
Fact-Check: According to WPScan, the number of new vulnerabilities being discovered has been steadily rising in recent years. In 2020, over 4200 new vulnerabilities had been discovered. An additional 729 new vulnerabilities have already been discovered in 2021.


Frequently Asked Questions

Q #1) Is OWASP ZAP a DAST tool?

Answer: Yes, OWASP ZAP is a decent dynamic application security tester that is also open-source and free to use. As a dynamic application security tester, OWASP ZAP analyzes an application from the outside-in to detect vulnerabilities it may possess.

The platform is one of the more popular black-box security testing being widely used in the industry today, which is also known for its penetration testing feature.

Q #2) Is OWASP ZAP legal?

Answer: Yes, it is completely safe and legal to use as long as you are using it to perform passive scans. Active scanning can be dangerous as it might modify, delete or create new data. Active scanning is especially illegal and may attract penalties if you are performing them on an application you don’t have any authorized access to.

Q #3) Is OWASP ZAP free?

Answer: OWASP ZAP is an open-source web application scanner that is absolutely free to use. In fact, it is one of its defining characteristics and can be attributed to the appeal it enjoys among security teams and developers even today. Its free nature means the tool isn’t exactly flawless.

For instance, people using the tool have often complained about a high number of false positives being detected. It is wise to use this tool along with any of the tools we have listed in this tutorial.

Q #4) How do I run a ZAP scan?

Answer: Running a ZAP scan is simple. All you have to do is follow the below steps:

  • Launch ZAP and click the ‘Quick Start’ tab on your workspace window.
  • Now click the large button – ‘Automated Scan’.
  • You will see a text box referred to as ‘URL to Attack’. Simply paste the URL you want to simulate an attack on.
  • Click ‘Attack’ after pasting and your scan will begin.

Q #5) What is AJAX Spider in ZAP?

Answer: Ajax Spider is an add-on designed for crawlers known as Crawljax. The add-on can allow OWASP ZAP to crawl web applications that are written in AJAX. Developers use AJAX Spider only if they have to run scans on applications exclusively written in AJAX.
