Elite audio/visual and IT systems that disappear into the architecture—reference-grade sound, clean video distribution, and concealed displays—built on a hardened backbone. We engineer segmented networks, governed remote access, and defenses against Wi‑Fi leakage and evil‑twin attacks so performance and privacy stay intact. Includes: VLAN segmentation • hardened edge (firewall policies) • secure Wi-Fi design (leakage + evil twin defense) • secure remote access • device isolation • privileged admin controls • logging/monitoring • rack/cabling standards • AV distribution + control integration
