The challenge

What the client needed

Ageing identity infrastructure was creating authentication failures, support overhead and audit risk.

Our approach

How we worked

  • Assessed risk and friction points across citizen identity journeys.
  • Introduced modern identity federation and policy-based access controls.
  • Migrated users in controlled cohorts with rollback safety and user comms support.
  • Transferred capability to internal service teams with documented runbooks.
Outcomes

Measured results

All details are anonymised in line with our standard confidentiality terms.

  • Authentication success rate improved materially across web and mobile channels.
  • Support contacts related to login issues reduced by 46 percent.
  • Audit preparation time decreased with stronger identity evidence and controls.
