OTARIS tests IT systems, apps and IoT devices for security, data protection compliance and quality. Applications, websites, cloud and network infrastructures are analyzed in standardized security tests using vulnerability scans and penetration tests. OTARIS supports the implementation of an Information Security Management System (ISMS) and a Secure Software Development Lifecycle (Secure SDLC). Our experts advise on protocols, architectures and infrastructures of communication standards such as LPWAN (LoRaWAN, SigFox), ISM band and current mobile radio standards (LTE A-Pro, 5G NR-V2X, NB-IoT, 5G). We use end-to-end measurements to record the quality of service (QoS) and quality of experience (QoE) of communication networks and services. We provide support in the selection and implementation of 5G campus networks.
Our services
In all our services, we rely on trust-based business relationships with our customers. The expertise and high level of commitment of our employees as well as an open and transparent corporate culture form the foundation for good and successful cooperation.
IT security
We protect applications and cloud workloads holistically from architecture and code to operation. Hardening for containers and Kubernetes, secure CI/CD pipelines, identity and access management, encryption, continuous monitoring and compliance in accordance with ISO 27001, BSI C5 and SOC 2 reduce risks and create transparency.
Testing & Audits
Our security tests and audits uncover vulnerabilities at an early stage and provide clear recommendations for action. From penetration tests and code reviews to cloud and infrastructure audits, we test systems in a practical manner and in accordance with recognized standards such as OWASP, ISO and BSI. This gives you transparency and a reliable basis for secure decisions.
Training & Awareness
We strengthen your team with practical training and individual consulting. Whether threat modeling, awareness training, phishing simulations or compliance and risk management - we impart knowledge, optimize processes and support you in the secure development and operation of complex systems.
Development & Innovation
We research new security approaches, test ideas in proof of concepts and put future topics such as AI, automation and zero trust into practice.
