Cloud vs. on-prem access control: the 2025 decision framework

What cloud access control means

Cloud access control moves the "brain" of the system from a server sitting in your IT closet to the vendor's infrastructure. Door controllers talk to the cloud; you manage everything from a browser or app. Popular platforms in DFW: Brivo, Openpath (now Avigilon Alta), UniFi Access, Genea, Kisi.

Cloud pros

• No on-prem server to maintain
• Auto-updates, always current
• Multi-site management from one dashboard
• Mobile credentials native
• Lower upfront cost
• Easy to scale up or down

Cloud cons

• Monthly/annual subscription forever ($15–$35 per door per month)
• Internet dependency (most cache locally, but edge cases exist)
• Data residency / compliance concerns for regulated industries
• You're renting access to your own security infrastructure

On-prem pros

• No recurring subscription
• Full data control — everything stays on your network
• Mature enterprise features (time-and-attendance integration, complex approval workflows, compliance reporting)
• Works even without internet

On-prem cons

• Higher upfront cost (server, software licenses, implementation)
• Internal IT needs to patch, back up, and maintain
• Harder to scale to new locations
• Software updates often require re-training

The 2025 decision framework

Go cloud if:

• You have 3–50 doors
• You're a single or multi-site SMB
• You don't have dedicated IT for access control
• Your industry isn't highly regulated

Go on-prem (or hybrid) if:

• Regulated industry (defense, critical infrastructure, some healthcare)
• Legacy HR/identity system requires on-prem integration
• 100+ doors with dedicated security operations center
• No monthly OpEx possible in your budget structure

The UniFi Access wildcard

UniFi Access deserves a callout: it's cloud-managed but has no monthly subscription and can run fully on-prem if you want. That combination — cloud UX, on-prem cost structure — is why it's become our default recommendation for most DFW offices in the 5–25 door range. More in our Ubiquiti UniFi deep-dive.
