  • Quantum-safe crypto-agility that adopts post-quantum cryptography as standards adapt.
  • Federated governance to maintain ownership, retention, and audit across companies.

• Collaboration without barriers

  • Secure digital workspaces for each initiative, customer, or program.
  • Cross-company teams with precise roles, policies, and expiration windows.
  • Flexible deployment cloud, on-prem, or hybrid

How does Cyfer work?

1. Authenticate with our quantum-safe identities, or your enterprise identity provider
2. Spin up a secure workspace for a project, vendor, or contract
3. Invite internal and external members and AI agents with scoped permissions
4. Collaborate in real time—all messages, files, and data are end-to-end encrypted
5. Govern data with retention, legal holds, exports, and full audit trails

Frequently asked questions

Is Cyfer end-to-end encrypted?

Yes. Messages, conversations, and files are end-to-end encrypted so only intended participants can access content.

What is quantum-safe encryption?

Quantum-safe encryption uses algorithms built to resist quantum computer attacks, protecting your data as technology advances.

How is Cyfer different from Slack or Teams?

Cyfer is purpose-built for secure digital workspaces that extend across companies with federated governance, E2EE, and on-premises options.

Can external vendors join without creating risk?

Yes. External users are added into project-scoped workspaces with granular permissions, data boundaries, and automatic expiration.

Do we need to use the cloud?

No. Choose multi-tenant cloud, private cloud, or on-premises—then apply the same policies everywhere.
