Cybersecurity Hardening (MSSP)

Managed Firewall Services

Complete lifecycle management of your perimeter security gateways. We configure policies, inspect logs, and keep firmware patched.

Neglected Edge Firewalls

Default settings, legacy access rules, open remote desk ports, and unpatched firmware render expensive hardware firewalls ineffective against attackers.

Firewalls running vulnerable firmware targets for zero-day exploits.
Outdated rule lists allowing malicious traffic to enter corporate networks.
No logging analytics to detect active credential-stuffing scans.
Improper VPN access profiles exposing internal folders to third parties.

Defense Mandate

GavBit handles the configuration, testing, updates, and optimization of corporate firewall appliances. Our network security specialists establish rules based on the principle of least privilege, preventing lateral traffic movement while keeping remote access secure.
