Firewall

A network security device or service that filters traffic based on policy. Firewalls complement Zero Trust security by limiting attack paths and are often managed through cybersecurity services for consistent updates.

Why it matters

Firewall can affect uptime, security, compliance, cost, and the way teams get work done. A clear understanding helps leaders ask better vendor questions and avoid preventable disruption.

Where this shows up in operations

  • Projects stall because Firewall is not clearly owned or explained.
  • Security, reliability, or reporting gaps appear when Firewall is implemented without a plan.
  • Budget and planning conversations get harder when Firewall is disconnected from business risk.

How MNI helps
