DTMF Security Policy: keeping door-open codes out of sight

Five and a half years ago, CyberGate entered the market with a clear mission: connecting IP intercoms directly to Microsoft Teams, so organizations can answer the door, see who is there and make announcements from the app they already use every day.

Today CyberGate supports over 1,500 enterprise customers in more than 35 countries, is trusted by 35 Fortune 500 organizations worldwide, and connects four device types to Teams: IP Video Intercoms, IP Paging systems, IP Cameras and Body Worn Cameras. That reach raises the bar on the details that are easy to overlook. The door-open code is one of them.

A door code is a secret, so treat it like one

Many organizations open the door by entering a code on the Teams keypad after answering an intercom call. It is a quick, familiar gesture, and that is exactly what makes it easy to forget what the code actually is: a key to your building. Anyone who reads it somewhere can walk in.

Until now that code left a trail behind it in the CyberGate Management Portal, readable by anyone with portal access. DTMF Security Policy closes that gap.

What changes when the policy is enabled

With DTMF Security Policy enabled, the door-open code entered by the Teams user is no longer visible anywhere in the CyberGate Management Portal:

• Not in the read-only Audit Trail
• Not in the Call Log
• Not in the Device menu

The door still opens exactly as before. Only the record of which digits were pressed disappears, so the code cannot be harvested from the portal after the fact.

The policy is enabled by default for all new customers as of July 2026. Existing tenants can switch it on themselves whenever they are ready.

How to enable or disable it

• Enable. In the CyberGate Management Portal, under Global Settings, on the Security tab.
• Disable. To prevent accidental exposure, portal admins cannot disable it themselves. Use the “Request disable DTMF security policy” button on the same tab and our support team will follow up.

That asymmetry is deliberate. Turning protection on should take one click; turning it off should involve a conversation, because the consequence of doing it by accident is a building code sitting in a log that more people can read than you think.
