Network Security Overhaul for a Multi-Site Business

A 100+ employee multi-location construction firm had outdated firewalls, exposing them to cyber threats. I upgraded security infrastructure across 5 offices by replacing legacy firewalls with SonicWall NSA series, improving intrusion prevention. I also deployed site-to-site VPNs for secure inter-office communication and implemented WPA3 encryption and VLAN segmentation for Wi-Fi security. As a result, the firm saw a 65% improvement in network performance, zero security breaches in 12 months, and full compliance with industry cybersecurity standards.
