Helping Direct Line Group migrate to new infrastructure

How DLG completed a fast, efficient and secure migration to new infrastructure

When Direct Line Group (DLG) separated from the Royal Bank of Scotland, it needed to migrate all its services and digital assets to a new infrastructure securely, efficiently, and within a tight deadline.


  • Establish a secure new infrastructure for DLG’s data and services
  • Securely migrate data from the infrastructure previously shared with RBS
  • Complete the migration quickly, with minimal downtime


  • Team of 8 CACI Network Engineers, Consultants and Service Delivery Managers helped migrate to a new iSNP (Interim Secure Network Perimeter) – a mission critical piece of security infrastructure which allowed for RBS hosted applications to continue to be consumed by 12,000 DLG employees (including RBS desktops) and allow for data to be transferred as part of the migration activity between RBS and the new DLG data centres.
  • Working alongside the core IT staff within DLG and other key suppliers, all aspects of network implementation and management were taken care of
  • Full support before, during and after the migration
  • Dedicated team of CACI experts remains both on-site and remotely to manage the new infrastructure


  • DLG laid the foundation for a successful digital future
  • Migration was completed quickly, avoiding potential fees from RBS
  • A secure network perimeter was established which has been running since 2013
  • The CACI team has helped DLG with multiple other challenges – reaching out further into the business and helping the organisation master its network and data
