Company

Company Fastly Imperva
Short profile Founded in 2011, Fastly has grown into a mature CDN provider. Fastly offers a range of services including streaming media delivery and private CDN but Fastly is best known for being a 'real-time CDN', meaning changes happen instantly and the platform can deliver 'uncacheable' content well. Imperva's CDN (formerly Incapsula) makes your websites and applications faster, more reliable and safer. A global network of servers provides content caching, load balancing and failover, while an enterprise-grade cloud web application firewall and DDoS protection safeguard your site from the latest threats.
