Lumen Defender℠ Powered by Black Lotus Labs® blocks traffic based on threat level and IP address. Defender Essentials blocks traffic on Lumen provider edge (PE) using an ingress filter, while Defender Plus blocks traffic on several locations in the Lumen network using an egress filter.
Use the information below to determine if traffic to or from an IP address is being blocked, potentially by Defender.
Note: Defender Essentials doesn't affect latency. Defender Plus can cause minimal latency on inbound traffic because it shifts traffic to the nearest Defender server. Use ping and traceroute to determine latency.
