Operational value
Post-quantum protection across the full fabric lifecycle
21Packets is designed to reduce Harvest Now, Decrypt Later exposure by protecting more than traffic in motion. Post-quantum principles govern identity, admission, key establishment, policy distribution, attestation, session authority, and DEFT tunnel operation around every authorized Endlet.

Identity, key establishment and every session on the fabric use crypto-agile, post-quantum algorithms.
Inside the capability
Cryptographic assurance that can evolve with the threat.
The 21Packets model applies post-quantum principles across secure enrollment, identity validation, session establishment, route and policy distribution, attestation, and DEFT tunnel operation—not only the payload traveling through the fabric.
Identity-bound
Session authority and key material remain tied to an authorized, machine-validated Endlet identity.
Long-term protection
The architecture is designed to reduce Harvest Now, Decrypt Later exposure for protected historical traffic.

Why it matters
Turn capability into operating advantage.
Protect long-lived operational data
Reduce the risk that encrypted traffic captured today becomes readable when future cryptographic capabilities advance.
Bind cryptography to machine trust
Release route state, policy, session authority, and key material only to identity-bound, machine-validated Endlets.
Evolve without replacing the endpoint model
Use crypto-agile profiles so approved algorithms and key policies can change while the Endlet operating model remains consistent.
How it operates
A coordinated path from policy to operation.
