DDoS protection · Hong Kong

Keep websites, servers and networks online under DDoS attack.

NetIO Limited protects Internet-facing infrastructure against distributed denial-of-service attacks. We filter traffic on our own network — and we license the mitigation software behind it to operators who prefer to run filtering themselves.

Our services

DDoS protection for websites, servers and networks

Three ways to connect, one filtering engine. Whether you run a single website, a rack of servers or an autonomous system, traffic is scrubbed before it reaches you.

Engagement

Two ways to work with NetIO

Let us operate protection for you, or take the same software and run it inside your own network. Many operators start with the service and move filtering in-house as they grow.

Managed by NetIO

Protection as a service

We assign the addresses, run the filtering nodes and carry the operational load. You connect over DNS, a tunnel or BGP and get protection as a subscription.

  • No filtering hardware or capacity to buy
  • Website, server and network connection models
  • Protected IPv4 and IPv6 addresses included
  • 24/7 support and incident escalation

The platform

One engine behind every service

A modular protection platform built in-house, delivered as installable packages for industry-standard servers running supported Linux distributions.

Packet-level filtering

Analyses and filters incoming traffic at OSI layers 3 to 5 to mitigate volumetric and protocol-based attacks before they reach your infrastructure.

Application-level filtering

Inspects HTTP and HTTPS traffic to detect and block application-layer attacks, malicious bot activity and common web-application threats.

Management subsystem

Unified administration through a web interface and a documented API — configuration, monitoring, reporting and integration with your own operational systems.

Why NetIO

Engineering-led, fair, and in your control

We own the technology

The filtering software is written by our own engineers, so we adapt to new attack vectors quickly and can build what a customer actually needs instead of waiting on a vendor.

Hardware-independent

Everything runs on standard commodity servers and supported Linux distributions — no proprietary appliance, and materially lower cost per protected gigabit.

Transparent pricing

Pricing is calibrated to protected traffic and resources, and quoted up front — no opaque success fees, no per-attack surcharges, no penalty for being attacked.

24/7 expert support

Round-the-clock technical support staffed by engineers with hands-on operational experience — the people who run the platform, reachable when it matters.

Who we serve

Whoever cannot afford to go offline

From a single business website to an autonomous system carrying other people's traffic. The connection model changes; the protection behind it does not.

Service providers

Internet service providers, hosting and cloud providers, data-centre operators and telecommunications operators — protecting their own infrastructure, and reselling protection to their customers.

Online business

E-commerce, SaaS platforms, online media, streaming and game operators — where an hour of downtime is measured directly in lost revenue and lost users.

Enterprise & institutions

Corporate infrastructure, financial platforms, APIs and public-facing portals that have to stay reachable regardless of what is pointed at them.
