More about Assistant

Federated chat and video calls

Nextcloud Talk supports federated collaboration. Join group chats on another Nextcloud server and use many of the core features like user mentions, markdown formatting, or polls. And even organize audio and video meetings across different Nextcloud Hubs — to meet with colleagues from another department, or maybe a partner who is using Nextcloud too.

End-to-end encrypted calls

Nextcloud Talk now supports end-to-end encrypted calls for sensitive communication, both when accessed via web and through the new desktop client.

Unique protection

Nextcloud Talk protects your communication better than other team collaboration platforms like Microsoft Teams or Slack, making sure your data stays on your servers. Nextcloud Talk goes further than other encrypted communication technologies by keeping even metadata from leaking. This ensures you stay in complete control of communications.

Designed for privacy

Nextcloud Talk is a fully self hosted, on premise 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. Message status indicators show when a message is sent and received – for more privacy, users can disable this on their side.

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. Configurable visibility on chats allows team members and/or guests to find and join open chat rooms.

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.

Integrated groupware, chat and project management

Nextcloud features tightly integrated chat, project management, mail, calendaring and more. Chat messages can be directly transformed into tasks, task deadlines are visible in the Calendar and files can be attached to a task from the sharing dialog. A single platform means there is no need to juggle different accounts, keep track of where in the many cloud platforms the latest version of a document is floating around, or worry about security threats and invisible costs.

Bridging with other networks

Nextcloud Bridging allows the connection of Talk rooms to one or more channels on other Talk servers, but also 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 bridged 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 permissions for audio/video and screen sharing. Schedule meetings and be notified when they start. A lobby is provided for guests to wait until the call starts. Moderators can let a selected guest in early. Participants can raise their hand to get attention or be allowed to speak.

Video verification

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 is the only solution that consolidates all essential functions for efficient collaboration into a single application, while ensuring full data control and independence. It’s the only high security collaboration platform also deployable in airgap environments.

It benefits from the many security, encryption and authentication capabilities of Nextcloud. It’s 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.

The most popular self-hosted collaboration solution for tens of millions of users at thousands of organizations across the globe

Compliance

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.

ePrivacy Regulation

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.

Why metadata and self hosting matter

Metadata, often described as everything except the content of your communications, has less legal protections but can be incredibly revealing. From a list of who somebody talks to and when, much can be inferred!
The Electronic Frontier Foundation explains it well on their site.

Of course, service providers might promise not to store and track such meta data, but governments can simply force them if need be. For example, in the UK providers have been forced to record the website visits of their customers.

And that is not even mentioning the fact that even privacy-focused companies can suddenly be sold to a foreign entity. Like with the content of communication, the best way to protect metadata is to ensure it never leaks from your infrastructure in the first place.

Scalability

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.

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. Enterprise limits, however, are in the thousands of participants per call.

Scaling in enterprise setup

To help with scaling, Nextcloud lowers video quality automatically and disables video on large calls. 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 video streams.

The High Performance Back-end offered by Nextcloud solves the bandwidth bottleneck and allows scaling a single call to much larger numbers of participants, up to hundreds or even thousands.

Scaling further: webinars, school classes

High Performance Back-end

Webinars and other large scale broadcasting type calls are possible with hundreds or thousands of participants. The High Performance Back-end setup includes special features for this.

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 premise, like Nextcloud itself, or through a hosted offering by our partners. Customers should be aware that it has significant dedicated bandwidth and processing needs. The HPB is available through Nextcloud GmbH.

Sign up for a free 30 day test of the hosted HPB offering in the Talk settings page.
