How do you handle security and compliance?

Security is built into every engagement: data encrypted in transit and at rest, role-based access control, logging and monitoring, and audit-ready configuration. For regulated industries we design to the relevant standard, for example HIPAA-ready systems for healthcare. We sign an NDA before any engagement, so your systems and data stay confidential from the first conversation.
