Securing a Global Investment Bank's Hybrid Cloud
Zero-trust architecture across 38 offices, 4,200 endpoints migrated to continuous authentication — with zero operational downtime.
Financial Services
A Bank Operating at Global Scale with Legacy Security Foundations
When a top-20 global investment bank approached Kryphos, their hybrid cloud infrastructure had grown faster than their security controls. Thirty-eight offices across 14 countries, on-premise data centers in three regions, and a rapidly expanding cloud footprint — all connected by authentication systems that hadn’t been meaningfully updated in seven years.
The bank had experienced three internal audit findings related to privileged access in consecutive years. Regulators were watching. Leadership wanted a solution that could modernize security posture without disrupting trading operations, client services, or any of the 4,200 endpoints already in production.

THE CHALLENGE
Legacy Access Controls at Enterprise Scale
The bank’s authentication infrastructure was fragmented across three identity providers, with no unified policy enforcement. Privileged accounts were over-provisioned by default, and lateral movement between segments was possible without triggering any alerts.
- No unified identity policy across 38 offices and 3 cloud regions
- Over 1,200 privileged accounts with excessive standing access
- Zero visibility into east-west traffic between network segments
- Manual audit preparation taking 6+ weeks each cycle
- 3 consecutive regulatory findings on privileged access controls
OUR APPROACH
Zero Trust. Zero Downtime.
We phased the migration carefully — validating each segment before cutting over, with automated rollback triggers at every stage.
01
Discovery & Mapping
Catalogued all 4,200 endpoints, 1,200+ privileged accounts, and all identity provider configurations across 38 offices. Produced a unified risk map within 10 days.
02
Policy Architecture
Designed a least-privilege access model with just-in-time provisioning for all privileged roles. Policies were validated in a shadow environment before any production changes.
03
Phased Migration
Rolled out zero-trust controls office by office, starting with lowest-risk segments. Each phase included a 72-hour validation window before proceeding. No trading systems were touched until all satellite offices were stable.
04
Continuous Monitoring
Deployed behavioral analytics across all segments post-migration. Any deviation from established access patterns triggers automated review and optional containment within 2.4 seconds.

Of prior regulatory findings resolved in the first post-deployment audit review
“Kryphos delivered what no other vendor had been able to — a complete zero-trust migration across our global footprint without a single hour of trading system downtime. The regulatory findings that had plagued us for three years were closed in our very next audit.”
