TL;DR: A global gift card retailer used browser-level masking and selective unmasking to protect gift card codes, personal data, and financial data in distributed support workflows, while keeping SaaS applications unchanged, according to Island. The governance lesson is that visibility control, auditability, and onboarding speed must be designed together, not treated as separate operating goals.
NHIMG editorial — based on content published by Island: the case of the exposed gift card codes
Questions worth separating out
Q: How should support teams protect redeemable codes in SaaS workflows?
A: Use default masking for any value that can be redeemed, reused, or monetised, and apply it at the workflow layer where staff actually view the case.
Q: Why do support tickets create data exposure risk for customer service teams?
A: Support tickets often aggregate personal data, financial data, and sensitive codes in one place, which means broad ticket access can expose more than the task requires.
Q: What breaks when sensitive values are visible to all support agents?
A: Least-privilege support design breaks down because every agent can see a bearer value that may be redeemed outside the case.
Practitioner guidance
- Define sensitive-data masking rules for support workflows Identify code formats, account numbers, and other bearer values that should be hidden by default in customer service sessions.
- Restrict unmasking to explicit escalation roles Create a small set of approved roles that can reveal masked values when needed, and require each reveal to be logged with user, case, timestamp, and justification.
- Treat support onboarding as a visibility-design event Before adding new support staff, define what classes of personal, financial, and redeemable data they can see on day one.

- How the browser-based masking workflow was configured for gift card codes in support tickets
- How escalations users can unmask sensitive values when a valid business need exists
- How the management console records reveal events for audit and review
- How the enterprise browser approach avoids changing the underlying SaaS applications

Browser-layer masking is a governance control, not just a presentation feature. The core issue in this case is that sensitive values live inside support workflows that the underlying SaaS application does not natively govern at the right granularity. Masking at the browser layer changes who can see the code without requiring application change, which is useful when customer service teams operate across distributed environments. The implication for practitioners is that visibility policy belongs where the work happens, not only where the application stores the record.
A question worth separating out:
Q: How do you know if masking controls are actually working?
A: Look for fewer unrestricted exposures of codes, a small and well-justified set of unmasking events, and complete logs for every reveal. If staff routinely bypass masking or the exception process is informal, the control is not doing real governance work.
