Tempesta FW is the first and only hybrid of HTTP accelerator (reverse proxy) and firewall, specially developed for Application level DDoS mitigation and building high performance Web Application Firewalls (WAF). Tempesta FW is embedded into Linux TCP/IP stack, uses the fastest HTTP parser and NUMA-aware Web-cache with modern hardware optimized data structures. Tempesta FW outperforms modern HTTP servers in x8-12 times and scales linearly on multi-core hardware and many concurrent TCP connections. High performance filtering framework with drop-early strategy equiped by advanced traffic classification module based on machine learning algorithms delivers reliable DDoS protection and outstanding Web-content acceleration under normal conditions. Tempesta FW accelerates Web-content in accordance with recent HTTP standards RFC 7230-7235 as well as with RFC 2616. Webacceleration in both with robust filtering provide solid platform for filtering CDNs. Tempesta FW provides unique technology, Generic Finite State Machine (GFSM), and ultimate set of hooks on all network layers. Thus, any complex classification logic, including challenge-response, can be done on top of Tempesta FW. Tempesta FW provides an extensive set of load balancing methods. HTTP requests can be distributed among backend servers via complex conditional statements over any HTTP headers and IP addresses. Tempesta FW is pure software solution which delivers 10Gbps performance on commodity hardware, so it can be used similarly in virtual machines. Tempesta Technologies Ltd. is a subsidiary of NatSys Laboratory Ltd. which was founded in 2008 and specializes in high performance and distributed computing.
