Best Web Application Firewalls (WAF) for Microsoft 365

Qualys Web Application Firewall (WAF) is a service based on virtual appliances designed to streamline application security while minimizing operational costs and complexity. Utilizing a cohesive platform, it consistently identifies threats using proprietary inspection logic and rulesets, and can provide virtual patches for web application vulnerabilities as necessary. Its straightforward, scalable, and flexible methodology enables rapid blocking of web application attacks, safeguarding sensitive information from exposure, and regulating access to your applications.
