Why we built EntryBit — rethinking access control
The story behind a cloud-native take on physical access control — and why we think the category was long overdue for a rewrite.
The problem we kept running into
Every company we talked to had the same story: their access control system was installed by a contractor five years ago, runs on a Windows XP machine in a server closet, and nobody really knows how it works anymore.
These systems were designed in an era when “cloud” meant weather and “API” meant nothing to a facilities manager. They work — sort of — but they’re islands. They don’t talk to your identity provider, your HR system, or your incident response tools.
What we set out to build
We wanted access control that felt like the rest of your stack: cloud-native, API-first, and designed for teams that move fast.
That meant a few non-negotiable decisions from day one:
- Hardware-agnostic. We refuse to lock customers into proprietary controllers. EntryBit works with every major protocol and manufacturer.
- Real-time everything. Every door event, every credential change, every policy update — streamed in under 50 milliseconds.
- Enterprise integrations out of the box. Entra ID, Okta, Slack, Google Calendar, SendGrid — not as afterthoughts, but as first-class citizens.
Where we are today
EntryBit manages access for facilities across 12 countries, processing millions of events per month. Our controllers reconnect in under 300 milliseconds after network drops. Our audit logs are tamper-evident with cryptographic chain verification.
We’re just getting started. If your access control system feels like it belongs in a different decade, we’d love to show you what modern looks like.
