BGP hijacking lets attackers silently reroute internet traffic, bypassing firewalls, zero-trust architectures, and encryption inspection. Despite available defenses like RPKI, adoption gaps leave most enterprises exposed. Using recent real-world incidents, this session reveals how routing-layer attacks enable data interception, service disruption, and supply chain compromise — threats invisible to traditional security tooling. Attendees will learn how BGP monitoring and route origin validation close this blind spot, and what security teams should demand from their network and ISP partners.
