Episode notes

How do you modernize security in a 180-year-old company that operates critical national infrastructure? What does it look like when you discover tens or even hundreds of thousands of credentials hidden across your estate?

In this episode, we sit down with Christian Schwarz, Security Director for Network Services at BT Group , recorded at HashiDays London. Christian shares the immense challenge and strategic approach to standardizing secret management across one of the world's oldest telecommunication companies.

He details BT's journey away from the "moat and a castle" security model towards a future with no passwords for developers , reducing friction and enhancing security by design.
