Best in Class Approach

Strictly owner-related cryptographic access control guarantees you data sovereignty and security at all times - no compromises when it comes to your data.

Encrypt and scramble the data

olmogo not only encrypts data at the point of origin but also metadata and keys. That means no readable information leaves your device (= zero information). For further security, data is broken up into small fragments.

No Trust Design

With olmogo you don't have to trust an administrator, a provider or olmogo itself. olmogo is not based on trust but on control by the user. So that security is not just a promise, olmogo is open source.

Separated Server Systems

For even more security, user data, storage locations and information data are stored on three completely independent server systems. Only the owner in the middle can bring the data back together.

Simple and easy

Thanks to its intelligent architecture, olmogo can be easily integrated into the existing IT infrastructure. Open, transparent interfaces allow the use of the olmogo storage and sharing technology. The developer only cares about the business logic.


Innovative key management allows data to be handled conveniently as usual. Usability and performance are retained, olmogo takes care of the complex rest in the backend. Keys remain under your control even with (multi-) cloud and business networks.

Frequently asked questions

Use cases

Application scenarios

S3 - Communication
Patient and client data are in good hands in olmogo.

Medical offices, medical networks and clinics use olmogo for communication with each other and with authorities. Protecting and managing patient-related data is complex. olmogo treats data strictly owner-related, so the patient is always the focus. olmogo can be easily integrated into existing infrastructure such as the practice system or the clinic system so there is no UI break.

Olmogo is also very popular with lawyers, notaries and tax advisors in order to be able to communicate securely with clients. The popular email or fax is no longer compliant with data protection. olmogo offers professional groups with trust status a simple and secure alternative for their communication.

M3 - IoT
Automotive industry and IoT

Connected driving delivers huge amounts of data. These must be stored and managed in compliance with the GDPR. olmogo can store data under the sovereignty of one or more identities. For example, the car manufacturer can save and manage the data for the customer, get access to the necessary data records and at the same time comply with the rights of the 'data subject'. Since the mogo is unchangeable per se, it represents the single source of truth of the respective data set. This ensures that data remains unchangeable when needed. Technical users - so-called olmogo agents - can be authorized to analyze data in real time and take actions if necessary.

olmogo also manages data in complex access and legal relationships without great administrative effort, for example in data lakes, business networks or even in interaction with the owner from the perspective of the GDPR.

M3 - Corporate Data
Protect company data as best as possible

The management, protection and secure communication of confidential or data relevant to data protection is a challenge. Both SMEs and large corporations are required to protect (data) assets and to act GDPR-compliant by ensuring their data sovereignty 100%. olmogo M3 offers you a middleware that you can easily integrate into your existing IT infrastructure such as SAP, Office, etc. Your data is provided with an owner-related cryptographic access control. This means that the data is only accessible to authorized identities, is stored in compliance with the GDPR and can be made available to third parties safely and easily (by parts) if required. There are several ways to share data: simply by clicking on one or more other olmogo users, using the mogo box for not yet olmogo users or by email via your usual email client.

With olmogo you can store your company data on premise or entrust it to a cloud without hesitation.

M3 - hochsichere Cloud
Use of hyperscalers without loss of data sovereignty

When using cloud services, you have to trust the provider. All risks defined by ENISA occur. Not so with olmogo: use the innovative encryption from olmogo to maintain your data sovereignty. Especially with multi cloud solutions, olmogo is a one stop shop solution. No matter how many clouds you connect, the effort remains the same, olmogo manages your keys at the location of your choice and you are in control.

M3 - Blockchain
olmogo offers the solution for many blockchain disadvantages, especially in the area of ​​smart contracts

Blockchain applications use olmogo technology as off-chain storage to manage storage and access to documents. By saving multiple redundant data storage within the blockchain, the performance, storage space and costs are optimized. Within the olmogo architecture it is still possible to comply with the request for changes and deletions within the meaning of the GDPR.

olmogo is the ideal addition to blockchain applications to avoid the inherent disadvantages of pure blockchain applications.
