Self-hosting communication simplifies compliance with national and international privacy and security regulations.
By relying on existing, vetted infrastructure, your current compliance and security processes apply to Nextcloud Talk.
GDPR, CCPA and more
The GDPR (General Data Protection Regulation) makes organizations liable for any violations of user privacy and deviations from a high data security standard.
Legislation like the CCPA (California Consumer Privacy Act of 2018) brings similar regulation to other countries.
Nextcloud has extensive GDPR compliance capabilities.
The upcoming EU ePrivacy Regulation is designed as a complement to the GDPR. The objective is to reinforce trust and security in the Digital Single Market by ensuring that electronic communications from Europeans are confidential regardless of the technology used. The ePrivacy Regulation protects the confidentiality of electronic communications and information on devices, independently whether it is personal or non-personal data.
Nextcloud is designed to protect the confidentiality of communications and fully prepares customers for the upcoming ePrivacy Regulation.

Designed for privacy
Nextcloud Talk is a fully self hosted, on-premises audio/video and chat communication service. It features web and mobile apps and is designed to offer the highest degree of security while being easy to use.
Nextcloud Talk lowers the barrier for communication and lets your team connect any time, any where, on any device, with each other, customers or partners.
While Nextcloud Talk itself is free, the optional Nextcloud Talk High Performance Backend enables enterprise class scalability, reliability and features.
Private, group and public calls
Talk makes it easy to call customers and partners in one-to-one or group-scenarios.
Users can invite external chat participants with an URL into public rooms on the Nextcloud server.
The chat, which remains open even when the user leaves a call, enables participants to easily exchange messages, links and notes.
Collaboration within Nextcloud
Documents can be shared directly into a chat from the Files app and are made available to all participants, both users and guests.
Projects integration enables linking of chat rooms with files, calendars, tasks and other resources for easy finding.
Our online office solutions provide a sidebar with Talk for chat and calls with the participants.
Drag a document into a chat and edit it with other participants during a video call
Bridging with other networks
Nextcloud Bridging allows the connection of Talk rooms to one or more channels on other services like IRC, Slack, Microsoft Teams, Matrix, Mattermost, XMPP and many more.
A bridge sends any messages from the third party network into the Talk room where it was configured, and any messages put in the Talk room to the bridget third party network.
Multiple networks can be bridged into a single Nextcloud Talk room, so messages can go from Slack to Teams and IRC via Nextcloud.
Webinars and presentations
Share the content of a single window or a full desktop screen for presentations with chat-partners.
Manage participants by inviting, muting or removing them.
Schedule meetings and be notified when they start.
A lobby is provided for guests to wait until the call starts.
Commands for productivity
Commands allows administrators to define actions users can call from a chat.
These can send their input back into the chat or kick off actions.
Commands are simple scripts, making it easy to integrate Nextcloud in business infrastructure.
Secure and private
Calls are end-to-end encrypted so no communication can be intercepted.*
Chat logs are stored securely on your own server.
The privacy of communication and its metadata is guaranteed by self-hosting Nextcloud Talk!
* Individual and group calls are 100% end to end encrypted without the High-performance Backend. When the HPB is used, all calls are routed through it. The HPB is self-hosted as well so no data leaks outside the server.
In situations where extreme security is warranted and the identity of a recipient has to be verified with absolute certainty before they are granted access, Nextcloud includes the industry-first implementation of Video Verification.
Video Verification enforces a Nextcloud Talk video call before access is given to a share, making sure the identity of the recipient is properly checked. The call can be picked up through the Nextcloud Talk Mobile apps as well as the web interface.
A platform you can trust
Nextcloud Talk benefits from the many security, encryption and authentication capabilities of Nextcloud.
Multi-layered encryption, brute force protection, artificial-intelligence based suspicious login detection, password-less login and the backing of our USD 10.000 security bug bounty program provide customers the confidence that their communication and collaboration remains confidential.
Easy for private use
Nextcloud Talk is designed for easy installation and operation. Nextcloud hosts a STUN server to facilitate usage behind firewalls and we recommend the installation of a local TURN server to improve connectivity further. Note that calls get fully routed through a TURN server, causing a lot of network traffic. Find documentation on installing a TURN server here.
The peer to peer nature of Talk does inflate network traffic, creating one incoming and sending stream per other participant. This places practical limitations on calls that depend on network capabilities. A typical private Nextcloud Talk setup should handle dozens of calls with each up to 6-10 participants, up to 20 if all participants have a good network connection and do not use video.
Scaling in enterprise setup
To help with scaling, users can disable video. Sending audio and video, as well as the compute power required to decode the video streams on clients, are the biggest limiting factors, with most asymetric internet connections bottlenecked on upstream bandwidth and laptops and mobile devices especially having trouble decoding multiple 480P/30FPS video streams.
The High Performance Back-end offered by Nextcloud partner Struktur includes a Selective Forward Unit (SFU) which solves this bottleneck by receiving one stream from each user and forwarding it as needed. This allows scaling a single call to about 30-50 active participants, up to hundreds when doing a webinar.
Scaling further: webinars, school classes
Webinars and other large scale broadcasting type calls are possible with hundreds of participants. The High Performance Back-end setup includes special features for this.
High Performance Back-end
The HPB also lowers the load from calls on the Nextcloud server, taking care of 'signaling' and optionally enables connecting a SIP bridge so users can dial in by phone into calls.
The HPB runs on-premises, like Nextcloud itself, or through a hosted offering by Struktur AG. Customers should be aware that it has significant dedicated bandwidth and processing needs. The HPB is available through Nextcloud GmbH.
