Telesign provides digital identity verification and customer engagement solutions for enterprises. The company was founded in 2005 to address online identity challenges and enable secure digital transactions globally. Telesign's core offering centers on phone number intelligence and verification. The company verifies over five billion unique phone numbers monthly, representing approximately half of the world's mobile users. Their platform analyzes phone numbers across thousands of attributes to determine the identity of users in milliseconds, helping businesses prevent fraud during onboarding and throughout the customer lifecycle. The company's solutions address four key areas: onboarding, account integrity, fraud protection, and engagement. Their technology combines digital identity verification with global communications capabilities, delivered through APIs that integrate into enterprise systems. Telesign uses machine learning and data science to provide identity verification with speed, accuracy, and global reach across more than 200 countries and territories. Telesign serves enterprise clients across multiple industry verticals, with strong presence in e-commerce, technology, software, and social media. Their customer base includes eight of the world's top ten internet companies. The company's approach focuses on what they call "Continuous Trust" - an ongoing process of connecting, protecting, and defending businesses and their customers rather than relying on one-time verification. Their product portfolio includes security, authentication, fraud detection, compliance, and reputation scoring solutions. The platform helps companies detect abnormal user behavior such as new devices, unusual locations, or atypical requests that may indicate fraudulent activity.
