Wisera Knowledge management for highly sensitive data
A highly secure wiki for organizations that want to manage their sensitive knowledge without the cloud – for all data that deserves special protection.
- Secure
- Made and hosted in Germany
- Hosted in a German data center or on-premises
- GDPR compliant
Knowledge management without the cloud
Standard wikis and cloud tools often do not offer the necessary control when the protection of particularly sensitive information and full data sovereignty are paramount. In scenarios where data security and data protection are a top priority and cloud solutions are not an option, makandra Wisera enables
- Compliance with even the strictest regulatory requirements – ideal for the financial, healthcare, and security sectors, for example
- complete control over all data, without external dependencies or data transfer across national borders
- reliable access even with limited or no internet connection, including maximum availability and performance
Maximum security integrated as standard
Our knowledge management platform is designed to be operated by us on your own dedicated server in a high-security data center in Germany, or on your own servers on-premises if desired. You retain full control over your data and benefit from sophisticated security features.
Your sensitive data securely hosted in Germany
Protect your sensitive data with wiki software hosted in Germany – highly available and scalable. While many providers operate their wikis in the US or with US corporations, we offer you secure hosting on your own dedicated server in a high-security data center in Germany. Unlike SaaS shared hosting, you get your own isolated server. On request, Wisera can also be hosted on-premises. If we take over the hosting, your servers are:
- Network -isolated
- Only accessible via VPN on request
- On solid ground in terms of data protection with your own AVV
Security in emergencies thanks to automated anomaly detection
- Automatic identification of activities outside typical working hours or unusual frequency of access.
- Monitoring unusual login attempts
Recording and reporting multiple failed login attempts or logins from new, previously unknown devices or IP addresses. - Analysis of conspicuous data access patterns
Detect when users suddenly access an unusually large amount of data or particularly sensitive data, which could indicate data misuse. - Warning messages for suspicious changes
Notification of changes or deletions of sensitive data, especially if these deviate from usual patterns. - Behavior-based user profiles
AI-supported analysis and comparison with typical user behavior to automatically detect deviations and report them at an early stage.
Additional features of Wisera
Compliance log: Always know what happened
Our wiki has an integrated compliance log that records all access and changes to sensitive data in detail. This log ensures that all actions are traceable and documented in an audit-proof manner. It meets important data protection and IT security requirements, especially when handling confidential information.
Compliance officers and auditors can evaluate the log at any time to identify violations or security risks at an early stage. The compliance log thus contributes significantly to risk minimization and transparency when handling highly sensitive data.
Classification with confidentiality levels
Public / Internal / Confidential / Secret: Your users in Wisera select the confidentiality level using the Classification drop-down menu. The classification appears prominently in the card details and on printouts, giving each user clear instructions on how to proceed with the respective content. At the same time, the access level ensures that only authorized user groups can view or edit the data.
The centralized solution eliminates the need for numerous individual settings per data record, minimizing errors and saving time.
FAQ about Wisera
Because data protection is non-negotiable. More and more companies and organizations are deliberately moving their highly sensitive data from the cloud back to their own networks or to high-availability data centers in Germany. Initial concerns about cloud-based solutions for sensitive data have not been dispelled—on the contrary, they are now more relevant than ever. Did you know that the CLOUD Act allows US authorities to access data held by US cloud providers?
An operation focused on security and data sovereignty gives you back full control over your data and creates the foundation for a secure, GDPR-compliant information architecture – without external dependencies and without cloud lock-in.
Yes – Wisera was developed from the ground up for on-premises use or use on dedicated servers. You retain full data sovereignty and operate the system either on your own servers or optionally (hosted by makandra) in a German high-security data center.
