Products offered by Limelight Networks:

Content delivery

Limelight's network infrastructure spans the globe with a QoS (Quality of Service) enabled network of about 120 Points-of-Presence (PoPs) in more than 45 metropolitan locations. Each Limelight PoP has a high density of fast servers with SSDs (Solid State Disks) resulting in one of the highest cache efficiency ratios in the industry, which means greater origin offload, better performance and lower bandwidth costs for Limelight customers. Limelight's private fibre backbone enables content to bypass the congested public internet, resulting in faster, more reliable, and more secure content delivery. Limelight owns and operates one of the world's largest private networks, which results in a superior user experience in a more secure infrastructure with the capacity to support the most onerous digital traffic demands. Unlike traditional CDN vendors who rely on third-party technologies for key components of their content delivery infrastructure, Limelight’s ongoing technology investments in its comprehensive EdgePrism software stack have produced breakthrough delivery performance by controlling the entire content delivery process.

Edge Cloud

Unlike traditional cloud service providers who rely on the congested public internet to transfer your critical data, Limelight operates one of the world’s largest private networks with global scale and reach that minimizes latencies. Limelight’s edge cloud eliminates the cost and complexity of using traditional cloud computing environments for low-latency IoT and edge compute applications. Limelight’s global private networkoffers the scale and reach you need to minimize latencies associated with typical cloud infrastructures by reducing the distance between your sources of data and the network edge. Its global private network includes ~120 Points of Presence (PoPs) in more than 45 metropolitan locations covering every region of the world. By strategically locating PoPs across the globe and through peering connections to more than 1,000 ISPs and leading public cloud providers, Limelight eliminates the latencies associated with sending information to distant data centers and enables critical real-time data processing and analysis.

Cloud Security

Limelight's cloud security services offer a layered defence against malicious website attacks and unauthorized content access without impacting the performance of your web applications and content delivery. Limelight DDoS Attack Interceptor protects against denial of service attacks intended to overload online services with large volumes of malicious traffic. Limelight Cloud WAF (Web Application Firewall) protects your web sites and web applications against malicious HTTP application layer attacks that are intended to compromise your web site and steal data. TLS/SSL capabilities encrypt data so it cannot be intercepted in transit, and multiple content security methods are available so only authorized users have access to your valuable content. Limelight offers a scalable range of cloud security solutions that protect your infrastructure and your content without impacting performance.
