Fastly Content Delivery Network vs Link11 Secure CDN: Side-by-Side Comparison (2026)

Fastly Content Delivery Network

Organizations shipping high-traffic applications need Fastly Content Delivery Network primarily for its real-time configuration control and instant purge capability, which let you push security fixes to edge servers without waiting for cache invalidation cycles. The platform covers three core NIST CSF 2.0 areas,infrastructure resilience, platform security, and continuous monitoring,with particular strength in the last two through real-time log streaming and anomaly detection at the edge. Skip this if your main concern is origin-layer protection; Fastly assumes your backend security is handled elsewhere and focuses exclusively on the perimeter and delivery tier.

Link11 Secure CDN

Mid-market and enterprise teams absorbing sustained DDoS campaigns will find value in Link11 Secure CDN's AI-driven threat detection operating across geographically distributed edge nodes, which catches volumetric and application-layer attacks before they reach origin infrastructure. The platform's continuous monitoring capability aligns with NIST DE.CM, actively identifying anomalies and blocking bot traffic in real time across multiple internet exchange points. Skip this if your priority is recovery and incident response tooling; Link11 is built for prevention and resilience, not forensics or post-attack analysis.
