Crypto Inventory and Crypto Agility: the foundation for security in the post-quantum era

Most organizations don’t have a lack of cryptography, they have a lack of visibility over it. Without a crypto inventory, we don’t know which algorithms we use, where they are, or what risks we are exposed to. This creates blind spots, increases compliance challenges, and leaves us vulnerable to scenarios such as Harvest Now, Decrypt Later.

But understanding is not enough, cryptography is constantly evolving, and we need the ability to adapt without disrupting the business. This is where crypto agility becomes key, enabling us to update and replace cryptographic mechanisms quickly and in a controlled way, responding to new threats, regulatory requirements, and the shift toward post-quantum environments.

The real value comes from combining both capabilities: visibility and adaptability, only then can we move from a reactive approach to a structured, future-ready security strategy.

At Telefónica Tech, we address this challenge through an integrated approach based on identification, protection, and governance, helping organizations turn cryptographic transition into a strategic advantage.
