Companies that use F5 BIG IP

Looking through these companies, I noticed F5 BIG-IP users are overwhelmingly financial institutions and government entities handling sensitive transactions and critical infrastructure. The banking sector dominates, from Norwegian sparebanks to Middle Eastern financial services, alongside insurance companies, government agencies, and utilities. These aren't tech companies building software. They're organizations moving money, protecting citizens, managing power grids, and delivering essential services where downtime or security breaches have serious real-world consequences.

These are definitively mature enterprises. The employee counts range from dozens to thousands, with many in the 50-200 range for regional banks and 1,000+ for larger institutions. Very few show funding stages, and when they do, it's post-IPO or debt financing, not venture capital. They have physical branch networks, long operational histories, and established customer bases. The few tech companies present (like Birlasoft with 15,000+ employees) are large service providers, not startups.
