F5, Inc. is an American technology company specializing in multicloud application delivery, API security, online fraud prevention, zero trust access, and enterprise AI workload security.
While F5 originally developed hardware-based application delivery controller (ADC) load-balancing appliances, the company has transitioned to a software-led business model. Software subscriptions and cloud-delivered services now account for a major portion of its product revenue, driven by a corporate shift toward predictable, recurring subscription models. The technological core of F5's platform portfolio is its Traffic Management Operating System (TMOS). F5 offers these services as virtual machines (branded as the BIG-IP Virtual Edition) that deploy programmatically across hybrid, multi-cloud, on-premises, and network edge environments to manage traffic, secure public APIs, and enforce zero-trust identity policies.
