F5, Inc.

An enterprise application owner pays F5 because a login flow, API and payment page have to stay fast and defended when ordinary demand spikes, credential stuffing starts, bot traffic probes checkout and cloud teams keep moving workloads around. The contract is not just a load-balancer bill. It prices application-delivery engineering, web application firewall policy, bot mitigation, threat research, appliance and SaaS support, cloud integration, global edge reach and enterprise help when the app is too important to fail quietly.
