One Edge. Many Origins.

Visitors connect to the ADC. Cached pages return instantly; everything else is routed to the healthiest backend.

Capabilities

Delivery, Perfected

Layer 7

Layer-7 Load Balancing

Smart request routing with least-load, round-robin and faster-response algorithms, plus session persistence and health checks.

Learn more Cache

Edge Caching with ESI

Run LSCache at the edge and serve cached pages — including ESI-punched dynamic blocks — before requests ever reach your backends.

Learn more TLS

SSL / TLS Offloading

Terminate TLS 1.3 with OCSP stapling and HTTP/3 at the ADC, freeing backend CPU for application work.

Learn more Cluster

WordPress & Magento Clusters

Purpose-built cluster modes keep caches coherent across nodes so scaling out never breaks your store or blog.

Learn more HA

High Availability

Active/standby failover with a shared virtual IP. If a node fails, traffic moves in seconds — without anyone noticing.

Learn more Security

Anti-DDoS at the Edge

Per-IP connection and bandwidth throttling, bot detection and reCAPTCHA stop floods before they touch origin servers.
