  • Encryption is always on — users can’t turn it off
  • Maintain incident response communications outside compromised systems
  • Keep leadership, security, and operational teams aligned
  • Powered by next-generation MLS for large-scale deployments

Give crisis teams control without exposing message content

During a live incident, you need governance without adding risk. Wire helps security and crisis teams manage access, identities, and external participation while keeping communications protected end to end.

  • Admins cannot view content or access message history
  • Set granular roles, classifications, and access rules
  • Verify identities and devices across internal & external users
  • Integrates with SSO, SCIM, and Active Directory
  • Revoke users or devices instantly and safely

Your teams move faster 
with communication that feels
simple and natural

A fallback channel only works if people actually use it. Wire gives teams a fast, familiar communication experience across mobile and desktop, so adoption is easier before and during an incident.

  • Intuitive messaging with reactions, threads, and sketches
  • Natural sharing of images, files, audio, and updates
  • Helps teams align across departments, time zones, & partners
  • Modern interface users understand the moment they see it
