Introduction

As enterprises embrace Zero Trust architectures, verifying “who you are” has become foundational, not just once at login, but continuously. In a Zero-Trust model, identity verification must be contextual, continuous, and risk-aware, whether for a human user, a service account, or a third-party vendor.

Legacy login systems and passwords are no longer sufficient. Instead, modern identity verification tools use multi-factor authentication (MFA), biometric matching, document scanning, behavioral analytics, and risk scoring to ensure only the right entity gets access, at the right time.

What is identity verification software?

Identity verification software helps to verify customers and provide a complete view of their fraud risk with physical and digital identity information. This view lets you conveniently onboard your customers by requesting only the necessary information at the right time and utilizing active and passive methods.

What is a Zero Trust Architecture?

Zero Trust Architecture (ZTA) is a security approach that assumes no user or device, regardless of location, is trusted by default and verifies every access request before granting access. It's a shift away from traditional perimeter security, where users inside a network were considered trusted. ZTA focuses on minimizing the attack surface and preventing lateral movement of threats within a network by requiring constant authentication and authorization for all access requests.

Why do we need Zero Trust?

Zero Trust is essential if your organization needs to address cyber threats like ransomware, supply chain attacks, and insider threats, especially if it must protect an infrastructure deployment that includes complex environments, unmanaged devices, legacy systems, and SaaS applications.

FAQ:

Which technology is used to verify a user's identity?

Biometric-based identification: Biometric identification uses physical characteristics to verify identity, including fingerprints, retina scans, and facial recognition.

What is one identity tool?

One Identity helps organizations strengthen cybersecurity, boost efficiency, and control costs through the One Identity Fabric, a holistic approach to identity and access management (IAM).

What is IAM verification?

Identity and access management (IAM) systems verify user identities and control user privileges.

Who uses identity verification?

It's commonly used in financial processes, such as opening a bank account, and it allows you to do business with or provide services to that person because their identity is verified.
