Managed service providers have never had more influence over their customers' security outcomes. Every day, MSPs make decisions that affect how organizations authenticate users, secure privileged
Quantum computers capable of breaking today’s encryption may still be years away, but France’s National Cybersecurity Agency (ANSSI) believes organisations shouldn’t wait to prepare. At the France Quantum Conference on June 16, 2026, ANSSI announced new milestones for the adoption of Post-Quantum Cryptography (PQC). ANSSI recommends that organisations prioritise purchasing quantum-safe security products by 2030.
The most important message, however, isn’t about 2030. It’s about what organisations should be doing today. ANSSI recommends that security teams:
- Inventory their cryptographic assets and sensitive data.
- Identify systems and applications that will eventually require updates.
- Ask cybersecurity vendors about their PQC roadmap.
- Incorporate post-quantum readiness into standard technology refresh cycles rather than treating it as a future migration project.
For CISOs, IT leaders and security architects, this marks an important shift. Post-quantum cryptography is no longer a research topic – it’s becoming part of long-term cybersecurity strategy.
Why post-quantum cryptography matters for organisations
Most of today’s digital security relies on public-key cryptography, including algorithms such as RSA and Elliptic Curve Cryptography (ECC). These algorithms remain secure against today’s computers. However, they were not designed to withstand attacks from sufficiently powerful quantum computers. While those computers don’t yet exist at the required scale, the risk already does. Security experts refer to this as Harvest Now, Decrypt Later (HNDL).
The concept is straightforward:
- An attacker intercepts encrypted communications today.
- They cannot decrypt the data with current technology.
- They store the encrypted data for years.
- Once sufficiently powerful quantum computers become available, they decrypt the information retrospectively.
For organisations protecting privileged credentials, secrets, intellectual property, financial records, healthcare data or government communications, the risk begins the moment encrypted data is stolen – not when it is eventually decrypted.
Credentials and secrets are particularly valuable because they can provide long-term access to critical systems and sensitive information. That’s why protecting the cryptographic exchanges used to secure them is becoming an increasingly important part of cybersecurity strategy.
This is exactly why ANSSI is encouraging organisations to begin preparing today. The objective isn’t to replace every security solution overnight but to understand where cryptography is used, identify long-lived risks and make future technology decisions with post-quantum readiness in mind.
How Keeper Security is helping organisations prepare
At Keeper Security, post-quantum readiness isn’t simply a roadmap – it’s already being rolled out across the platform.
Keeper has integrated quantum-resistant cryptography using a hybrid approach that combines proven elliptic curve cryptography with the NIST-standardised ML-KEM (formerly Kyber) algorithm.
This approach helps protect cryptographic key exchanges while maintaining compatibility with existing environments, enabling organisations to strengthen their security posture without complex migration projects or separate deployments.
For organisations following ANSSI’s recommendations, one question matters more than ever:
Does your cybersecurity vendor have a post-quantum roadmap?
Keeper Security does.
More importantly, that roadmap is already being implemented through quantum-resistant cryptography designed to help organisations prepare for the transition to post-quantum security.
What should organisations do next?
ANSSI’s Post-Quantum Cryptography announcement isn’t a call to replace every security product overnight. It’s a call to start planning.
Organisations that inventory their cryptographic assets, engage vendors early and incorporate post-quantum readiness into future technology refreshes will be better positioned for the years ahead.
If you’re evaluating your security stack and want to understand how Keeper Security can help your organisation prepare for the post-quantum transition, explore Keeper’s quantum-resistant cryptography documentation or request a demo to see how Keeper helps protect privileged credentials, secrets and sensitive data with a modern, future-ready security platform.
