Case Study: Doğugaz Natural Gas achieves secure, compliant network connectivity with Zyxel

Zyxel Pipes in Secure Network Infrastructure Solution for Turkish Natural Gas Supplier

Doğugaz Natural Gas, a Turkish natural gas distribution company serving offices across Bitlis, Bingöl, Muş, Tatvan, and Güroymak, needed a secure network infrastructure that could connect multiple sites, support Internet access for staff and guests, and meet strict legal logging requirements under Law No. 5651. The company turned to Zyxel for a wired and wireless solution that could provide site-to-site VPN connectivity, traffic separation, and compliant logging across its growing regional office network.

Zyxel implemented a secure infrastructure centered on Next-Gen Unified Security Gateways, smart-managed PoE switches, and business access points. The solution enabled centralized firewall-based logging of Internet and guest traffic at both IP and user levels, VLAN-based guest isolation, Turkish ID-based guest authentication, and easy account management through Zyxel One Network. As a result, Doğugaz gained a scalable, future-proof network with stronger security, centralized control, and compliant traffic logging across headquarters and branch offices.
