When Regulators Leave No Room for Error, Trust Can’t Slip

How a major UK bank modernized PGP encryption across three countries — replacing a legacy appliance with a cloud-native platform, preserving every key and flow, and clearing exhaustive regulatory scrutiny with feature parity intact.

Key Points

  • Feature-parity PGP migration, proven under scrutiny — every capability of the legacy appliance moved to the cloud intact, from PGP encryption with automatic secure portal fallback to inbound decryption and key harvesting, all cleared by the certifications and security evidence exhaustive regulatory review demands.
  • Hardware-backed key control, built in — as a SaaS platform running entirely on AWS, Echoworx leverages Amazon KMS and native Cloud HSM to generate, store, and manage every encryption key in hardware, satisfying the bank’s most stringent compliance mandates without compromise.
  • Full ownership of web access and traffic — integration with Akamai’s reverse proxy gave the bank complete control over SSL keys for web access, routing every portal exchange through its own trusted channels, while Entra ID SSO streamlined secure authentication end to end.
  • Controlled delivery, governed by the bank — automated verification tied new-user registration to the bank’s own identity-proofing standards, while controlled Reply All secured with verification codes let external parties collaborate safely, always initiated and owned by the bank.
  • Zero-disruption migration across three countries — thousands of public and private keys imported in bulk through secure web APIs, with a mirrored pre-production environment keeping every change tested and on schedule, so clients across the UK, Ireland, and Germany never felt the shift.

The lesson is clear: with the right cloud-native platform and a trusted partner, even the most heavily regulated institutions can carry every capability forward, prove compliance under exhaustive review, and modernize without missing a step. For the world’s most regulated organizations, secure communication is no longer a background function. It is part of the operating model, a cornerstone of resilience, and a daily demonstration that trust is being kept across every jurisdiction and every exchange.
