Cyber-Duck
London, United Kingdom
About
ISO-accredited digital transformation agency specializing in user-centred design for government, healthcare, and finance, operating since 2005. Now part of CACI Digital Experience.
Who They Work With
UK government and regulated enterprises needing ISO-accredited, GDS-compliant digital services—from the Bank of England to Handelsbanken.
Based on 14 documented clients · verified Jul 2026
Our Take
Cyber-Duck (now CACI Digital Experience) publishes detailed case studies for major UK institutions—the Bank of England project documents persona development, content strategy for 4,500+ pages, user testing, and measurable outcomes (308% social traffic increase, 30% longer session times).
ISO-certified across human-centred design (9241), quality (9001), and security (27001), with 170+ awards over 20 years.
Engagements skew long-term and capability-building—103 staff trained in service design at Handelsbanken, National Highways steered to its first GOV.UK Alpha pass in seven years—rather than one-off site builds.
Key strengths
- National Highways project passed GDS Alpha assessment on first attempt—directly relevant if your project must meet Government Digital Service standards
- Private sector clients visible alongside public sector: Handelsbanken, Worcester Bosch, Cadbury—the ISO-accredited process applies to commercial engagements, not just government
- Deloitte Technology Fast 500 recognition signals sustained business growth and operational maturity beyond design delivery
Good to know
- Now part of CACI Digital Experience—confirm team continuity and whether original Cyber-Duck principals lead your engagement
- ISO-certified process and public sector compliance overhead may mean longer timelines—clarify turnaround expectations upfront
