Setec Astronomy’s Shield is a turnkey RTBH (Remote-Triggered Black Hole) service that lets a single BGP-capable router drop malicious traffic upstream within minutes. It provisions a private ASN and a GRE or WireGuard tunnel to one of SATIS PoPs (Los Angeles, Dallas, Buffalo), generates copy-paste BGP configs for common platforms (Cisco, Juniper, pfSense, OpenWrt, VyOS, BIRD/FRR, OpenBSD, etc.), and shares a live, community-driven blackhole feed from AS23026 so attacks observed by other peers get auto-blocked for you. Blackholing works by announcing more-specific routes with a community tag so upstream routers silently drop traffic before it reaches your network.

Setup is self-service and auto-approved: a 14-day free trial with no card required, after which Shield is $59/month or a limited lifetime license at $9,995. No multihoming or prior BGP relationship is required; one router and a private ASN (64512-65534) suffice, and residential connections work if you place your own router behind the ISP gateway. Shield is effective against connection-completing attacks (brute force, exploit attempts, C2 callbacks) but not volumetric floods unless you enable uRPF or additional measures on your router. An API (2,000 req/day) and higher-tier Professional/Enterprise plans are available for larger deployments.
