Single secure network

Since any internet-facing network is exposed to the same threats, we maintain one compliant, secure, high-performance network for all customer traffic. This ensures a single platform for unified inspection and enforcement of both encrypted and unencrypted traffic flows.

TLS termination at the edge

We believe that implementing the highest standard of TLS encryption across your website shouldn’t slow it down. As part of our standard service, you can terminate secure TLS connections at our network edge, closer to users, offloading encrypted traffic from your web server for better performance.

Certificate hosting

  • Shared certificates allow customers to add their domain names (including wildcards) to the Subject Alternative Name (SAN) section of Fastly certificates. We take care of certificate procurement and distribution.
  • Hosted certificates allow customers to procure and upload their own keys and certificates, which Fastly will distribute to our caches. This service is often used for Extended Validation (EV) certificates, but we also support Organization Validated (OV) and Domain Validated (DV) certificates. We support Server Name Indication (SNI) for customers with modern clients, while customers with legacy clients can purchase dedicated IP addresses.
