Case Study: Avrasya Tüneli achieves continuous, automated end-to-end tunnel security and IoT protection with Palo Alto Networks

Linking Europe and Asia with a Complete, Connected Security Strategy

Avrasya Tüneli is a five-kilometer under‑Bosphorus road tunnel in Istanbul that carries about 50,000 drivers a day and operates with a 150‑person organization. Building a modern IT/OT environment with more than 2,000 IoT devices and nearly 400 cameras, the tunnel needed a single, automated security approach—visibility across network, endpoints and IoT and fast threat prevention—despite a lean, three‑person security team and the risk of manual, fragmented defenses.

Avrasya deployed the Palo Alto Networks platform (PA‑3200 ML‑powered NGFW, IoT Security, Cortex XDR and related services) to provide integrated, ML‑driven prevention, detection and response. The unified solution gave immediate device visibility (100% of IoT devices detected within 48 hours), stopped C2 activity via DNS protection, cut alert volume by almost 100%, enabled sub‑minute IoT policy rollout, and let the small team manage comprehensive security while keeping tunnel operations secure and efficient.
