Here is an overview of how SPR helps defend users against attacks with multicast services. The capabilities let SPR users enjoy the benefits of multicast while also being able to constrain the attack surfaces to trusted devices only.

Overview​

1. Every WiFi device is placed on its own VLAN and has a unique Group Key blocking Direct Station to Station Multicast traffic
2. We employ a configurable multicast proxy to relay whitelisted multicast services. It support mDNS and SSDP by default for ease of use. The multicast proxy and mDNS & SSDP relaying can be completely turned off though.
3. We also support setting a tag for multicast services to limit relaying traffic to only devices with the same tag applied.
