We have collaborated successfully with customers in highly security-critical environments. We adhere to security standards and best practices in all phases of the software development lifecycle (e.g. OWASP in web application development, e.g. HTTPS/SSL to ensure transport security, confidentiality and integrity).
We are accustomed to being challenged by 3rd party security agencies and pentests, in addition to comprehensive internal testing, not only during development but also in the operations phase.
