Tempesta® FW is an all-in-one open-source solution
For high performance web content delivery and advanced protection against DDoS and web attacks.
Tempesta FW is a drop-in replacement for an entire web server frontend infrastructure: an HTTPS load balancer, a web accelerator, a DDoS mitigation system, and a web application firewall (WAF).
Tempesta FW is the first and only hybrid of a Web accelerator and a multi-layer firewall. This unique architecture provides efficient blocking of any malicious traffic and outstanding performance of web applications in normal operation. The architecture is the result of collecting and application of state-of-the-art research and cutting edge technologies.
Tempesta FW services up to 1.8M HTTP requests per second on the cheapest hardware. The benchmark results are open and easily reproducible. Our performance results go beyond other modern web accelerators metrics.
The core of Tempesta FW is a scalable and ultra-fast network processing engine designed to handle tons of malicious traffic. The multi-layer rule-based and adaptive filtration facilities efficiently mitigate modern large DDoS attacks.
Application layer DDoS
Tempesta FW provides out-of-the-box rich rate limits, various challenges and adaptive QoS to guarantee good user experience during an attack and mitigate DDoS attacks such as slow HTTP, HTTP flood, iFrames, web cache bypass, targeted DDoS attacks, etc.
Tempesta FW works in the Linux kernel space, so it natively integrates with XDP to drop volumetric attacks on early packet processing stage or even on NIC using offloaded rules. Check our development services if you need a custom XDP module.
Tempesta FW automatically fingerprints and distinguishes web clients on all network layers. The fingerprinted client accounting information is available for an application custom code. Our team develops custom bots protection logic using the Tempesta FW classification engine.
We developed the fastest HTTP parser technology , which allows Tempesta FW not only process millions HTTP requests per second, but also do thousands of security checks right during HTTP parsing. Various injection attacks, including XSS and SQL injections, password crackers, HTTP requests smuggling and response splitting, cache poisoning and many others are filtered out at a speed larger than traditional web accelerators can parse HTTP messages.
Tempesta FW is a hybrid of web accelerator, load balancer, and application layer firewall. It analyzes HTTP traffic immediately as it arrives at a network adapter. Any malicious traffic is dropped early at the IP layer thus saving system resources for really useful work. You can read more about the use case in our knowledge base or blog post.
Tempesta FW uses a very fast ultra-scalable in-memory database Tempesta DB to handle a web cache.
The database employs a number of cutting-edge technologies such as cache-conscious lock-free burst hash trie for the index, NUMA-aware records distribution and replication, huge pages, zero-copy interfaces, and SIMD x86-64 extensions.
Tempesta FW provides a rich set of load balancing strategies such as persistent sessions, complex conditional statements over almost any set of HTTP request fields, weighted round-robin, rendezvous hashing, etc. Tempesta FW also uses machine learning to dynamically learn and predict changes in the performance and the availability of each of your backend servers, so there is no need to configure and maintain many different weights in your web cluster!
Application performance monitoring
Tempesta FW dynamically monitors upstream server performance and provides a comprehensive set of performance metrics. Application availability can be monitored using passive or active health monitoring techniques. Load balancing logic is integrated with the health and performance monitoring and dynamically changes traffic distribution among the upstream servers.
HTTP tables is an extension of standard Linux iptables, nftables and/or bpfilter for the network application layer, HTTP(S) protocol in particular. You can write multi-layer network filtration rules using Tempesta FW HTTP tables, e.g. filter all HTTP requests from a particular IP with a particular HTTP header. Learn more about HTTP tables in our knowledge base.
Tempesta TLS extends the Linux TCP/IP stack with the TLS protocol, so it avoids context switches unavoidable for traditional user space libraries and constructs TLS records in the most efficient way using the current TCP state data. Tempesta TLS also employs the modern asymmetric cryptography research and advanced zero-copy techniques. This all allows Tempesta FW to establish x2 more handshakes with x4 lower latency than Nginx using OpenSSL or WolfSSL libraries. TLS handshakes rate limiting efficiently mitigates TLS handshakes DDoS attacks.
Tempesta FW is designed to deliver the highest performance in HTTP processing under various workloads. High performance servicing of unusual traffic is crucial for resistance against complex DDoS attacks, including targeted DDoS attacks. Most types of HTTP floods can be mitigated without any configuration effort thanks to the fast processing engine.
How it works
Tempesta FW is embedded into the Linux TCP/IP stack and works in the kernel space, but administered from the user space just like any traditional web accelerators.
The reliability of a web cluster is extremely important. Please check the Wiki page for scenarios of highly available Tempesta FW installations.
Tempesta FW can be deployed in clouds as well as on bare metal. You can learn more about cloud installation in our Wiki.
