As of May 2026, there are 11 SaaS companies in Web Application Firewalls (WAF). They have combined revenues of $69.4M and employ 481 people. They have raised $59.7M and serve 20K customers combined.
A Web Application Firewall (WAF) is a specialized security tool designed to protect web applications by monitoring, filtering, and blocking malicious HTTP/S traffic. It acts as a barrier between web applications and the internet, safeguarding against various security threats such as SQL injection, cross-site scripting, and other vulnerabilities identified in the OWASP Top 10. WAFs are crucial for maintaining the integrity and availability of web applications, APIs, and mobile backends. The primary use cases for WAFs include real-time traffic monitoring, threat detection, and response to security incidents. They typically offer features such as custom rule sets, automated threat intelligence updates, and activity logging to help organizations meet compliance requirements and maintain security best practices. Common users of WAFs include IT security teams, application developers, and compliance officers, all of whom seek to enhance the security posture of their web-based services. Organizations often deploy WAFs as part of a broader cybersecurity strategy to ensure continuous protection against evolving threats while enabling secure digital interactions. WAF solutions may be integrated with other security tools, enhancing their effectiveness and providing a layered defense against cyber attacks.
