Start with your reality.
We examine existing systems, dependencies and requirements before recommending an approach. Together, we establish what needs to change, what can remain and which decisions matter first.
People. Technology. Responsibility.
We are OTOKO®. We connect software, cloud infrastructure and cybersecurity to make complex technology work for your business. From the first architectural decision to day-to-day operations.
How we work
A new platform rarely solves a problem on its own. We look at applications, infrastructure and processes together — and work with the people who use and operate them.
We examine existing systems, dependencies and requirements before recommending an approach. Together, we establish what needs to change, what can remain and which decisions matter first.
Software development, cloud architecture and security belong in the same conversation. We consider interfaces, access controls and operations from the start, so individual components form a working whole.
We turn concepts into working systems, support the transition and prepare teams for ongoing operations. Documentation, knowledge transfer and clear responsibilities are part of the delivery.


Inside OTOKO®
Our Cologne office brings people and ideas together. Meeting rooms, shared workspaces and quieter areas provide room to discuss architecture, work through technical details and plan the next step together.
We combine this personal exchange with collaboration across our locations. What matters is that the right expertise is available and decisions remain clear — wherever a project team works.

We build data platforms, automate data flows and develop analyses, forecasting models and AI assistants. You order a specific use case with a verifiable benefit, from the initial data review through integration to agreed operations.
AI alone does not answer questions of data quality, responsibility or cost-effectiveness. That is why we separate the tasks: making data available, understanding key figures, testing predictions and integrating generative models in a meaningful way. You can order each area on its own. For a complete project, we combine the results into a solution your employees can use within their existing workflows.
Custom software development, modernization of legacy systems, and reliable operation of your applications from a single partner.
Build custom software, web portals and apps, modernize existing systems and operate applications. Discover eight services from OTOKO®.
We advise on architecture, develop custom software, portals and apps, modernize existing systems and connect applications through interfaces. Testing, secure releases and maintenance are planned to fit the engagement.
Cloud strategy, migration, hybrid and multi-cloud architecture, and secure operations, in German data centers on request.
Enterprise cloud solutions from OTOKO®: strategy, migration, hybrid and multi-cloud, security, and Hosted in Germany operations. Get in touch today.
We develop your cloud strategy, migrate applications in waves, and build hybrid and multi-cloud architectures on Microsoft Azure, AWS, and Google Cloud. Encryption, key management with HSMs, and Hosted in Germany operations protect data and sovereignty. FinOps and managed cloud operations keep the platform available, secure, and economical over time.
We advise on selecting hardware security modules, integrate them into certificate services, applications and payment processes, and take on the agreed operation. From the key ceremony to recovery, the result is a solution with clearly documented responsibilities and security boundaries.
A hardware security module, or HSM for short, protects cryptographic keys and performs the designated operations within its security boundary. Whether it is to issue certificates, sign software or process payment data makes a considerable difference to the selection. We bring together device selection, application and operating procedures. Existing Thales, Utimaco, Entrust or IBM environments are assessed based on their specific configuration.
Assessment, penetration testing, zero trust, encryption, and detection and response from one team, aligned with ISO 27001 and NIS2.
