Two decades of BIG-IP appliances made it the default way enterprise traffic gets balanced, firewalled and inspected, and that installed base is hard to walk away from. No public price list exists; every deployment is a negotiated quote, subscription or perpetual. The vendor is publicly listed and run from Seattle, so the boxes inspecting your traffic answer to Washington twice over.

Why choose Link11 over F5?
The decisive argument is data jurisdiction. F5 is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Link11 removes that overhead. As a Germany-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
