Overview
Citrix, through its NetScaler product line, offers content delivery network (CDN) and application delivery controller (ADC) solutions focused on secure and optimized application delivery. The company provides load balancing, traffic steering, and security features like web application firewalls (WAF) and DDoS protection. Citrix serves enterprises, particularly those requiring hybrid cloud and on-premises solutions. Its customers include large organizations in finance, healthcare, and government sectors. The NetScaler platform integrates with major cloud providers like Microsoft Azure and Amazon CloudFront.
Streamroot was a provider of peer-to-peer video content delivery network (CDN) solutions, specializing in optimizing over-the-top (OTT) video streaming for broadcasters and content providers. Founded in 2013, the company developed Streamroot DNA™, a WebRTC-based technology that leveraged end-user devices to reduce bandwidth costs and improve streaming quality. It served clients like France Télévisions, Canal+, and Dailymotion, handling millions of daily video sessions globally. Streamroot was acquired by Lumen Technologies (formerly CenturyLink) in September 2019 and is no longer an independent entity, with its operations integrated or discontinued.
Network & Architecture
Citrix NetScaler operates a global network with points of presence (PoPs) across North America, EMEA, APAC, and LATAM, though exact PoP counts are not publicly disclosed. The platform emphasizes intelligent traffic routing and load balancing, leveraging global server load balancing (GSLB) for optimal performance. It is designed for hybrid deployments, supporting both on-premises and cloud environments. Regional strengths include North America and EMEA, with growing presence in APAC. Limitations may include less focus on smaller-scale or developer-centric use cases compared to competitors like Cloudflare.

History & Notes
—
Streamroot’s technology was notable for its hybrid approach, combining peer-to-peer delivery with traditional CDN infrastructure to reduce buffering and improve quality in bandwidth-constrained regions. Its acquisition by Lumen Technologies aimed to enhance video delivery in challenging markets like Eastern Europe, Asia Pacific, and Latin America. Some sources suggest Streamroot’s technology may still be integrated into Lumen’s CDN offerings, but no clear evidence confirms active use. Conflicting reports exist about its revenue and status at the time of acquisition, with estimates of sub-$5M in annual revenue in 2019.
