Edgio

Overview

Edgio was founded in 2001, headquartered in Phoenix, Arizona, United States, as a veteran CDN acceleration provider. Edgio was formed by merging Limelight Networks and Edgecast (formerly Verizon Digital Media Services), and acquired Layer0 (edge computing) in 2022, building an integrated platform covering CDN, security, video streaming, and edge computing.

Edgio's merger history reflects CDN industry consolidation: Limelight brings video streaming and large content delivery expertise, Edgecast was Verizon's CDN business, and Layer0 adds edge computing and frontend optimization. Together they make Edgio one of the few enterprise providers offering traditional CDN, security acceleration, and Serverless edge computing, serving many Fortune 500 and large media clients. Note that the brand is still in an integration transition with some product lines being unified.

Key Strengths

• Enterprise CDN performance and SLA: Stable network with comprehensive SLA (availability, latency, packet loss) for quality-sensitive scenarios.
• Integrated security: Built-in WAF and DDoS protection delivered on the same edge network without traffic chaining.
• Deep video streaming expertise: Uplynk provides live and VOD acceleration with HLS/DASH optimization, ABR transcoding, and low-latency live, proven in major sporting events; ideal for video streaming acceleration and OTT.
• Layer0 edge computing: Serverless edge scripts for request modification, A/B testing, and personalized routing; see edge computing trends.
• Global node coverage: Nodes across NA, EU, APAC, and South America with Anycast for nearest access.

Limitations

• Brand integration transition: Brand rebuilding after the Edgecast-Limelight merger; product lines and backends are being unified with inconsistent experiences.
