About CNX

What we believe

Digital sovereignty is not a policy position — it is an engineering outcome. A country's digital infrastructure is sovereign when the foundational services everything else depends on are built, operated, and governed from within that country.

When those services are operated by foreign entities, two things follow. Performance depends on international links that can fail or degrade. And accountability is governed by foreign law — which can compel changes, withhold records, or intercept data without local oversight and without notification.

Cambodia's government services, and digital economy deserve infrastructure that performs locally, fails gracefully, and answers to Cambodian law. That is what CNX exists to build.

What we have built

CNX operates Cambodia's sovereign digital infrastructure across four foundational layers.

Interconnection. CNX has operated Cambodia's national internet exchange since 2008 — an L2 switching fabric across six independent data centres in Phnom Penh. Traffic between local networks crosses at CNX: ISPs, content providers, cloud networks, and government institutions, all interconnected directly without transiting foreign infrastructure.

Naming. CNX hosts DNS root server instances at the exchange — supported by Packet Clearing House (PCH), APNIC, and Netnod — keeping the root lookup step inside Cambodia for locally originating queries. CNX also operates commercial authoritative DNS with anycast protection and DNSSEC, and encrypted recursive resolution for mobile applications. For institutions using CNX DNS services, name resolution stays entirely within Cambodia, on infrastructure governed by Cambodian law.

Time. CNX operates a Stratum-1 time service anchored by in-country Rubidium atomic oscillators. Time is a security control: every transaction log, every digital signature, every audit trail is a temporal assertion whose validity depends on the server knowing what time it is — accurately, verifiably, and without interference. CNX replaces the anonymous public NTP dependency with a cryptographically authenticated, domestically governed signal.

Secure access. CNX operates ZTAN — a Zero-Trust Application Network that gives mobile banking applications a sovereign transaction channel from device to bank core. The channel stays entirely within Cambodia, under the bank's own certificate authority, with no CDN or foreign proxy in the path.

How we operate

CNX operates shared infrastructure under four published principles: neutrality, non-discriminatory access, transparency, and verifiable accountability. Open access criteria, equal pricing, and the full policy are on the Neutrality page.
