  Encrypted file transfer, access controls, NDAs, and privacy compliance for sensitive data (PHI/PII, legal, R&D).

  Compatibility with CAT/TM, TMS, connectors (CMS, code repos), multimedia pipelines, and an explicit policy for MT/AI usage and MTPE.
• Scalability and support
  Dedicated PMs, surge capacity for peaks, transparent SLAs, and real‑time program reporting.
