It is widely used by penetration testers, network administrators, and security researchers to discover vulnerabilities in WiFi networks. While it is a powerful tool for legitimate security assessments, its presence on Windows environments often raises questions regarding installation, compatibility, and functionality.
Even if you could bypass the driver issue, Fern relies on:
