When SCM was looking for a simple, secure and well designed messenger platform that could be hosted on-premises, a decision was made for Nextcloud Talk. A Professional Services project from Nextcloud GmbH provided several features SCM required and today, the legal, human resource, financial and PR experts of SCM can easily communicate and collaborate during their business trips.

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.
In addition to online data storage, Nextcloud Hub (…) offers groupware components for mail, contacts and calendar. Nextcloud Talk fits in seamlessly here, so all in all the whole thing is more of an alternative to Microsoft Teams or Slack.

Bridge with other servers and chat networks
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.
Message status indicators show when a message is sent and received – for more privacy, users can disable this on their side. The Nextcloud Talk High Performance Backend enables enterprise class scalability, reliability and features.
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.
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
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.
Benefits of a single platformOne application that is very useful during audio/video calls or chat sessions is Nextcloud Whiteboard. It is a collaborative whiteboard with the ability for all participants to draw lines and shapes, take notes and write text, upload images, give a presentation and more.
Files created with Whiteboard are saved among other regular files and can thus easily be shared.

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.
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.
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.
Security in Nextcloud
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.
If you want to have a call with many people, see tips in our documentation.
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 AG 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.
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.
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.
Sign up for a free 30 day test of the hosted HPB offering of Struktur AG in the Talk settings page.
The Nextcloud Talk High Performance Backend for large organizations by Struktur AG offers the capacity, reliability and features enterprises need to conduct their business privately, securely and efficiently.
