Network Security Check
Our security systems flagged some unusual activity from your network. To continue using Lumen services, please verify your identity.
Why am I seeing this?
This is a routine protection measure. Here are the most common triggers:
Unusual Traffic
Sudden spikes in requests from your IP address or connections from multiple geographic regions in a short window.
Network Config
Specific corporate proxies or VPNs change how your traffic appears to our servers, triggering our security protocols.
Shared IPs
If you're behind a shared or dynamic IP address, you might see this check when your neighbors trigger our filters.

"When our corporate VPN tripped Lumen's check, the team cleared us in 20 minutes. Painless."
Priya Sharma, Frontend Lead
"We use Lumen daily for our client work. The rare security check is a small price for the peace of mind."
