We sit down with the Goldilock team to challenge the default “add more software” mindset and focus on a blunt truth: if a network is not connected, it cannot be hacked from the outside. We dig into how Layer 1 physical disconnection works with existing security tools, what it means for installers and PMs, and why protecting backups and controlling third-party access can change your blast radius overnight. 
• Physical network disconnection as Layer 1 defense 
• Why software-only security becomes an arms race 
• Picking disconnect points based on a risk register 
• Bulkhead and light switch analogies for technicians 
• Using APIs to trigger disconnects from existing security tools 
• Timeouts, default states, and safe reconnection practices 
• Ransomware reality and why attackers go after backups first 
• Retrofit and rack installation considerations for a 1U device 
• Manual firmware updates, maintenance windows, and validation audits 
• Third-party access windows with auditing and certainty 
• Coordinating installers, PMs, IT, and OT through labs and simulations 
• Future direction as AI speeds up attacks
