How Callsign CIAM Works

Access management is not treated as a single checkpoint. Callsign continues to verify the user throughout their journey, using behavioural, device and location intelligence to confirm identity silently in the background. When everything matches known trusted patterns, the experience remains effortless. If something changes, the system adapts in real time and applies the right form of step-up authentication.


Access decisions are based on context and risk, ensuring users reach only what they are entitled to and that sessions cannot be hijacked.

Users can manage their own profiles and privacy preferences, and organisations maintain clear compliance transparency.

A single customer identity profile enriched with real trust signals allows personalisation, fraud detection and better customer experience design.

Customers can register easily, including seamless migration from previous CIAM solutions. This can be done progressively during normal usage or through a bulk transition, depending on strategy.

Why Callsign's CIAM is different

The only CIAM platform powered by Digital DNA, continuously recognising genuine users for secure, seamless and personalised digital experiences.

Securely manage customer identities across registration, login and ongoing access - using intelligence to stop fraud without adding friction.

Focus on external users

Unlike traditional Identity and Access Management (IAM), which focus on employees, CIAM is designed for managing external users such as customers, partners or end users.

User experience

Create seamless and intuitive access experiences, minimising friction during login and registration to improve user retention.

Security and compliance

Provides robust security by authenticating user identities, detecting fraud and managing customer data in complete compliance with privacy regulations.

Personalisation

Callsign CIAM helps organisations understand customer behaviour, enabling personalised services and improved experiences which builds trust.
