F5 Networks, Inc. is an US-American-based company that specializes in application delivery networking (ADN) technology for the delivery of web applications and the security, performance, availability of servers, data storage devices, and other network and cloud resources. F5 is headquartered in Seattle, Washington, and has other development, manufacturing, and sales/marketing offices worldwide.
Known originally for its load balancing product, today F5's product and services line has expanded into all things related to the delivery of applications, including local load balancing and acceleration, global (DNS based) load balancing and acceleration, security through web application firewall and application authentication and access products, DDoS defense, and more. F5 technologies are available in the data center and the cloud, including private, public, and multi-cloud environments based on platforms such as AWS, Microsoft Azure, Google Cloud, and OpenStack.
F5 Networks, originally named F5 Labs, was established in 1996. The company name was inspired by the 1996 movie Twister, in which reference was made to the fastest and most powerful tornado on the Fujita Scale: F5.
F5's first product (launched in 1997) was a load balancer called BIG-IP. When a server went down or became overloaded, BIG-IP directed traffic away from that server to other servers that could handle the load.
In 2010 and 2011, F5 Networks was on Fortune's list of 100 Fastest-Growing Companies. The company was also rated one of the top ten best-performing stocks by S&P 500 in 2010. F5 was also named a Best Place to Work by online jobs and recruiting site Glassdoor in 2015 and 2016.
François Locoh-Donou replaced John McAdam as president and CEO on April 3, 2017.
On May 3, 2017, F5 announced that it would move from its longtime headquarters on the waterfront near Seattle Center to a new downtown Seattle skyscraper that will be called F5 Tower. The move will occur in early 2019.

F5's BIG-IP product family comprises hardware, modularized software, and virtual appliances that run the F5 TMOS operating system. Depending on the appliance selected, one or more BIG-IP product modules can be added. Offerings include:
- Local Traffic Manager (LTM): Local load balancing based on a full-proxy architecture.
- Application Security Manager (ASM): A web application firewall.
- Access Policy Manager (APM): Provides access control and authentication for HTTP and HTTPS applications.
- Advanced Firewall Manager (AFM): On-premises DDoS protection, data centre firewall.
- Application Acceleration Manager (AAM): through technologies such as compression and caching.
- IP Intelligence (IPI): Blocking known bad IP addresses, prevention of phishing attacks and botnets.
- BIG-IP DNS: Distributes DNS and application requests based user, network, and cloud performance conditions.
On September 7, 2004, F5 Networks released version 9.0 of the BIG-IP software in addition to appliances to run the software. Version 9.0 also marked the introduction of the company’s TMOS architecture, with significant enhancements including:
- Moved from BSD to Linux to handle system management functions (disks, logging, bootup, console access, etc.)
- Creation of a Traffic Management Microkernel (TMM) to directly talk to the networking hardware and handle all network activities.
- Creation of the standard full-proxy mode, which fully terminates network connections at the BIG-IP and establishes new connections between the BIG-IP and the member servers in a pool. This allows for optimum TCP stacks on both sides as well as the complete ability to modify traffic in either direction.
Subsequent releases enhanced performance, improves application security, and supported cloud application deployments.
F5 describes BIG-IQ as a framework for managing BIG-IP devices and application services, irrespective of their form factors (hardware, software or cloud) or deployment model (on-premises, private/public cloud or hybrid). BIG-IQ supports integration with other ecosystem participants such as public cloud providers, and orchestration engines through cloud connectors and through a set of open RESTful APIs. BIG-IQ uses a multi-tenant approach to management. This allows organizations to move closer to IT as a Service without concern that it might affect the stability or security of the services fabric.
Silverline is a cloud-based application service. Its offerings include security services such as WAF and DDoS protection services.
Cloud, container and orchestration solutions
In 2017, the company introduced technologies to make F5 capabilities more portable across a broader range of IT environments, including:
- Application Connector connects public clouds to application services infrastructure within cloud interconnect or data center environments. This further enables the use of public cloud resources while also performing workload discovery and deploying consistent app services across multi-cloud deployments.
- Application Services Proxy is an automated traffic management proxy that provides F5 services (and service portability) with containerized environments.
- Container Connector combines F5’s application services platforms (including BIG-IP and Application Services Proxy) with native container environment management and orchestration systems such as Kubernetes, RedHat OpenShift, Pivotal Cloud Foundry, and Mesos.
