As remote and hybrid work models stabilized in 2022, enterprise IT departments faced unprecedented bandwidth and security pressures. Traditional perimeter firewalls often choked under concentrated VPN tunnel traffic.
Key Architectural Upgrades:
- Split Tunneling Policy: Route SaaS traffic (Microsoft 365, Zoom) directly through encrypted local interfaces while piping internal data center connections through the corporate firewall.
- Multi-Factor Authentication (MFA): Enforce hardware token or TOTP verification at the RADIUS / TACACS+ authentication layer.
- Interface Load Balancing: Deploy multi-WAN router configurations to prevent ISP line degradation during peak hours.
