Nextcloud is designed to protect user data through multiple layers of protection.
Our customers care deeply about security and so do we. Nextcloud aligns with industry standards such as Clause 14 of ISO/IEC27001-2013 and related standards, guidance and security principles. Our solution is built around combined assurance layers consisting of rich security features, applied best practices governed by policy and the design itself validated by industry standard testing processes.
Nextcloud supports your existing storage solution, keeping data under control of trusted IT administrators and managed with established policies. Nextcloud works with industry standard SQL databases like PostgreSQL, MySQL and MariaDB for user and metadata storage.
Nextcloud offers built in monitoring tools and integrates with existing MDM, DLP, event logging and backup tools, enabling existing tool chains to be used to monitor, backup and restore systems
Nextcloud leverages existing data storage and database technologies so current security policies and governance processes can continue to be used to manage, control and secure operations with Nextcloud. Your IT department is fully in control.
Nextcloud understands the necessity to provide core principle baseline security requirements, as such Nextcloud 11 is built on these security principles to ultimately deliver a secure solution to their customers
The second largest city in Switzerland, Geneva, contracted Swiss IT Security firm Kyos to audit the Nextcloud code base they use.
Besides active security measures like authentication and encryption, Nextcloud protects your data without any need for administrator action
Nextcloud employs a wide variety of extra security hardening capabilities, including:
CSP 3.0 is the latest, most strict version of the standard, increasing the barrier for attackers to exploit a Cross-Site Scripting vulnerability.
Same-Site cookies are a security measure supported by modern browsers that prevent CSRF vulnerabilities and protect your privacy further. Nextcloud enforces the same-site cookies to be present on every request by enforcing this within the request middle ware.
We include the __Host prefix to the cookie (if supported by browser and server). This mitigates cookie injection vulnerabilities within potential third-party software sharing the same second level domain.
Password security is extremely important and Nextcloud follows the latest and most strict standards.
We go beyond these standards, checking passwords against the database of compromised accounts and passwords from well known security researcher Troy Hunt. This optional but highly recommended feature ensures users can not reuse a password which has been compromised on another website already. Read our blog to learn how this feature protects your users.
The native SAML integration negates the need for external software like Apache modules. Native SAML is compatible with all web servers and supports group memberships, flexible session management and app specific passwords. It can handle multiple Identity Providers and can authenticate to Samba servers with Kerberos.
Nextcloud is also among the first in the industry to provide support for the WebAuthn standard, enabling password-less authentication and support for Windows Hello, various FIDO2 keys and other standards-compliant authentication devices.
Nextcloud offers a series of advanced security features:
For Nextcloud customers, securely exchanging data is key. Nextcloud offers industry standard protection mechanisms and adds innovative and unique capabilities like Video Verification.
Nextcloud features industry-leading protection for file shares.
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.
While Nextcloud supports Mobile Device Management solutions, thanks to build-in support, remote wipe will work on systems not under management of the company. This is useful for home users but also large universities and of course in a scenario where guest accounts were handed to a third party. If you permit downloading of documents by the third party, you can wipe the documents from their devices when the the collaboration has ended.
Remote wipe can be used on a per-device basis by users and on a per-user base by the administrator.
In settings where a firewall is needed between departments or organizations without impeding smooth and efficient collaboration, a separate Virtual Data Room can be set up. Nextcloud offers a wide range of unique features for VDR use and its on-premises nature offers unparalleled confidentiality and control.
