Private Discuss vs Wire

HD video meetings up to 1,000 participants

Vendor features and contact pages state secure HD audio/video conferences for up to 1,000 participants with screen sharing, virtual backgrounds, collaborative whiteboard, breakout rooms, live polls/voting, and in-meeting electronic signature—aimed at executive and sensitive operational meetings rather than consumer calls.

Large-scale webinars with role and recording control

Webinar tooling includes organiser/presenter/participant roles, granular permissions (present, share, record, content access), interactive stage, moderated hand-raise, secure chat/reactions, and HD recording with encrypted storage and controlled access. Contact materials claim capacity up to 1 million participants for large virtual events.

E2EE messaging, files, and co-editing in one suite

Instant messaging covers 1:1 and group/channel chat with presence and mentions; secure file and media sharing (up to 20 GB per message via PiTransfer per marketing); cloud co-editing and a document library for sensitive document workflows. Security pages claim non-disableable E2EE, AES-256 for real-time calls, and RSA-2048 for file sharing.

Sovereign deployment: SaaS, on-prem, or air-gapped

Hosting options include fully managed cloud SaaS, on-premise/private servers behind the customer firewall, and use cases marketed for air-gapped or constrained networks. Privacy policy states encrypted message storage on servers hosted in France; GTS state EU hosting without transfer outside the EU for personal data in scope.

Admin suite, kill switch, and policy controls

Administration covers local/regional admin roles, user and group management, time-based access, contact and file-sharing authorisations, activity monitoring, minimum client version enforcement, MFA, geographic access limits, custom retention, and remote revoke/wipe language for compromised devices—built for security teams governing a closed network.

In-house AI tools for identity and translation

Marketed AI features include deepfake/identity verification using camera, microphone, and device signals; real-time meeting translation; Private Translate for sensitive text/documents without content leaving customer infrastructure; and an AI companion for transcription, decisions, and post-meeting summaries—positioned for closed environments rather than public LLM APIs.

Always-on MLS / E2EE for chat, calls, and files

Messaging, conference calls, and in-app file shares are end-to-end encrypted by default—no toggle. Wire markets full-product MLS (IETF Messaging Layer Security) for scalable group key exchange, alongside Proteus/Double Ratchet heritage for pairwise messaging and SRTP/DTLS for calls. Suits orgs that reject optional encryption modes.

Guest rooms and external collaboration

Invite outsiders into E2EE conversations via guest rooms in the browser without requiring a full account download, plus external team members with lifecycle controls (removal drops their history access). Practical for contractors, clients, and inter-org projects that must stay off consumer WhatsApp.

Cloud, on-premises, air-gap, and federation

Run managed Wire Cloud or deploy on-premises/private cloud—including air-gapped networks—with optional federation between isolated Wire backends and admin control over which backends may interconnect. Aimed at governments and CNI that cannot accept pure SaaS only.

Enterprise identity: SSO, SCIM, and admin policy

Enterprise tier adds SAML-based single sign-on, SCIM provisioning, and granular admin controls (for example enforce app lock, restrict self-deleting messages). Built for complex directories rather than only self-serve SMB signup.

Open-source clients, server, and crypto

Wire publishes client, server (wire-server, AGPL-3.0), and core-crypto components on GitHub for independent review. Multi-device accounts (up to 8 devices) with ID Shield certificate-based device verification reduce manual fingerprint workflows while keeping device trust visible.
