Network Protection

    Protect your network & ASN

    Bring whole IP ranges, subnets, or your own ASN behind always-on Layer 3/4 mitigation. We absorb volumetric and protocol floods upstream and deliver clean traffic over GRE or BGP.

    How clean traffic reaches you

    Route your whole network through Sterile in whichever way fits your setup. We scrub upstream and hand back only clean traffic.

    GRE tunnel

    Receive fully scrubbed traffic over a GRE tunnel to your infrastructure with no hardware to install.

    • Clean traffic delivered to your edge
    • Works alongside your existing routing
    • Per-range or whole-network

    BGP announcement

    Announce your own prefixes through Sterile with BGP and we filter everything in front of them, continuously.

    • Keep advertising your own IP space
    • Always-on, full-network coverage
    • Bring your own ASN

    Built for your whole edge

    One place to protect every host, subnet, and prefix you run without onboarding services one by one.

    Whole-subnet coverage

    Protect entire /24s and beyond in one place instead of onboarding every host and service individually.

    Volumetric mitigation

    Large L3/L4 floods are absorbed at the edge, far from your origin.

    Your IPs, your ASN

    Keep advertising your own address space and ASN while traffic is filtered transparently in front of it.

    Always-on, not on-demand

    Mitigation runs continuously rather than triggering after impact, so attacks never get a head start.

    Protection you can measure

    Always-on mitigation across your entire network edge.
