We investigate the "Firewall Crisis" where the four dominant vendors—Cisco, Fortinet, SonicWall, and Check Point—collectively contributed over 50 actively exploited vulnerabilities to CISA's catalog, effectively transforming defensive appliances into primary attack vectors. The discussion uncovers how this systemic failure enabled the Akira ransomware group to generate $244 million by targeting Cisco VPNs and allowed the Qilin group to cripple healthcare systems by exploiting Fortinet flaws. Finally, we analyze the "Zero-Day Paradox," exploring how security giant Check Point was breached twice in nine months by its own research, signaling the urgent need for organizations to abandon perimeter reliance in favor of Zero Trust.
