We get into:
- How Benny bootstrapped OPSWAT and built a common language that let antivirus, VPN, firewall, and encryption products talk to each other
- Testing every antivirus on the market with live malware, and what it showed about real-time protection vs file scanning
- Why multiscanning with 30 engines still let malware through
- How CDR rebuilds JPEG, PDF, and Office files to strip buffer overflow exploits before they land
- Data diodes, one-way optical firewalls, and securing file flow into air-gapped networks
- Offline patching, and why critical infrastructure teams need their own training (OPSWAT Academy)
Benny's book, Cybersecurity Upside Down, covers the statistics and architecture behind all of this.
