Security APIs for seamless, trusted digital experiences

Trust is the foundation of the digital economy. Security APIs enable you to launch new products and services fast without compromising security and user experience. Protect every transaction and customer, enhance application security, and mitigate fraud with real-time intelligence while lowering costs.

Enhanced fraud prevention and user experience

SMS-based verification creates user friction and security failures. With Number Verification and SIM Swap APIs, you can mitigate risks in real time while improving the user experience.

Number Verification

The Number Verification API confirms a user’s mobile phone number possession in real time by verifying it directly with the carrier’s network, with minimal or no user input. Use this API to replace one-time password logins with silent authentication, mitigating fraudulent sign-ups and automated abuse of developer platforms.

SIM Swap

The SIM Swap API operates in the background to provide real-time information about recent SIM card changes associated with a mobile phone number. You can detect SIM changes instantly and trigger additional security checks if a risk is identified.

The dual challenge of staying ahead of threats and protecting brand reputation

The scale and prevalence of identity fraud are accelerating, fueled by trends such as generative AI, expanded digital onboarding, and availability of exposed consumer data. Your customers are aware of this threat more than ever, and they expect you to proactively safeguard their personal information.

Enhance security without compromising UX

SIM swap fraud has emerged as one of the fastest-growing types of identity theft, and the volume of incidents is escalating. This trend makes OTP authentication less secure because fraud actors can intercept SMS communications. OTP also adds user friction, often resulting in abandoned onboarding flows.

Aduna’s Security APIs address these issues by operating in the background to prevent unauthorized SIM swaps, verify identity, and enable secure digital transactions. For example:

Financial institutions can integrate SIM swap data into their risk decision engines and query the SIM Swap API during suspicious transactions.
E-commerce, social media, ride-sharing, and similar companies can use the Number Verification API to automatically verify a device-associated phone number, streamlining user authentication during onboarding.

This approach enhances security and improves the customer experience. By protecting accounts and reducing friction, you build trust, maintain brand reputation, and reduce fraud risk.
