F5 keeps applications running and secure, even when millions of people hit them at once. The company was founded in 1996 in Seattle.
For most of its life F5 sold hardware. Its BIG-IP boxes sit in data centers and balance traffic across servers. If one server gets swamped, BIG-IP sends the next request somewhere else. Apps stay up. Users never notice the juggling act.
The world changed, and F5 changed with it. Apps moved to the cloud and split into many small services. So F5 pushed into software and subscriptions. NGINX, the popular open source web server it acquired, gave it a huge developer following. F5 Distributed Cloud extends its traffic and security smarts across clouds and edge locations.
Security now sits at the center of the story. F5 shields apps from attacks, blocks bad bots, and protects the APIs that modern software leans on. Think about a bank running its mobile app across three clouds. F5 can apply one set of security rules to all of them at once.
Revenue runs around $2.8 billion a year. Software and recurring revenue keep taking a larger share of the mix. F5 is a steady, profitable veteran that is slowly trading its hardware roots for a software future.
