Closing security gaps

Deutsche Telekom runs its own Bug Bounty program to make its products more secure.

Within the Deutsche Telekom Bug Bounty initiative, weaknesses in the following web portals including subdomains are relevant:


Further notifications are, of course, welcome at any time, but are excluded from the reward program.

The Deutsche Telekom Bug Bounty program is an open program.

Minors may only participate with the consent of their legal representative.
