Release Highlights
MetaDefender ICAP Server now offers native integration with F5 NGINX, integration with Huawei OceanStor V6, available helm chart for Kubernetes deployment, and other enhancements.
Integration with F5 NGINX
Starting from version 5.1.0, integration between MetaDefender ICAP Server and NGINX has been enabled via a certified NGINX Dynamic Module.
NGINX provides a cloud-native reverse proxy, load balancer, web server and API gateway platform. Customers using NGINX in their current environments can add an additional threat prevention layer on top of NGINX Plus to protect their applications against file-borne malware, zero-day threats, and application file vulnerabilities. This is the first native anti-malware integration built for NGINX, extending OPSWAT’s Multiscanning and deep content sanitization technologies to support modern cloud application teams.
