Ten thousand sign‑ins, changed overnight.
Multi-factor authentication for more than ten thousand people and hundreds of applications on three continents. The cutover week was quieter than an ordinary Monday.
The brief
Strong, multi-factor authentication for every employee and every business application, across the Americas, Europe and Asia-Pacific, in a single program.
The difficulty
Sign-in is the one change everyone feels on the first morning. Hundreds of applications authenticated in different ways, regional teams had competing priorities, and leadership was watching closely. A bad cutover would have flooded help desks on three continents at once.
What we did
- Group
By how apps authenticate
Applications sorted into families, each proven in a pilot before anyone was moved.
- Resolve
Conflicts in planning
Regional priorities settled on paper, weeks before cutover, not during it.
- Rehearse
A runbook with rollback points
Every step written, timed and reversible.
- Cutover
A war room, sized for the worst
Staffed around the clock for the cutover week, across every time zone.
The result
- 10,000+
- Employees on multi-factor sign-in
- Hundreds
- Of applications moved
- 3
- Continents, one cutover plan
- Quiet
- Fewer help-desk calls than an ordinary Monday
The lesson
Drama in a migration is a planning gap that shows up late. Invest in pilots and runbooks, and the cutover becomes a non-event.
