Firewall Management & Security Audit Services
Your firewall is your first line of defense β but only if it’s properly configured and actively maintained. Bloated rule sets, outdated firmware, misconfigured VPN tunnels, and unmonitored open ports are silent risks that accumulate over time.
With 11+ years of enterprise firewall experience across banking, manufacturing, and critical infrastructure β managing 100+ physical and virtual firewalls simultaneously β I provide remote firewall management, optimization, and security audits for organizations that need a specialist without the overhead of a full-time engineer.
What I Do
π₯ Firewall Rule Management
- Review and cleanup of existing rule sets β removing redundant, shadowed, or overly permissive rules
- Policy optimization for performance and security
- Change management and documentation of every modification
- Compliance reporting (ISO 27001, PCI DSS, NIS2)
π VPN Setup & Optimization
- IPsec site-to-site VPN β new setup, troubleshooting, failover configuration
- SSL-VPN β remote access for users (Fortinet FortiClient, Palo Alto GlobalProtect, Cisco AnyConnect)
