Identity, Data and Privacy Security as One Unified API 

Circle powers frictionless cryptographic authentication, end-to-end data protection, and user-controlled privacy

We are on a mission to empower organizations to ELIMINATE the world's exposure to cyber threats.

Circle is the fastest way for organizations to shift left on their cybersecurity strategy from "detect & respond" to "prevent & eliminate!"

Why Circle Exists

Existing Solutions Fail to Prevent Identity Hijacking, Data Breaches, and Privacy Intrusion

Traditional MFA
Passwordless authentication isn't as secure as you think
Traditional MFA does not protect you from account hijacking and phishing
Identity Vulnerability
Identity is the gateway to 90% of breaches!
Credential compromise is the leading cause of cybersecurity breaches
The Cloud is Compromised
The Cloud is Compromised!
Protecting data and user privacy in a cloud-native environment is an increasing challenge
MFA Pain
Problematic User Experience
With higher levels of security, your application workflows, implementation and management negatively impact user experience

Transformative Security API Built on Next-Gen Architecture

Circle for Identity and Access Management

Authenticate every device and user without the need for any credentials enabled with the most secure, frictionless built-in MFA.
Continuously authenticate and verify identities throughout user journeys, not just at points of access to applications.
Tie your risk policies to Circle's step-up zero-trust identity verification - protect against fraud, identity theft, business email compromise, etc.
Secure Identity

Circle for End-to-End Data Protection

Securely exchange information and eliminate the attack surface in the Cloud using Circle's  decentralized key management technology.
Deliver verifiable trust into user experiences via Circle's event-specific cryptographic signatures and built-in immutable logs.
Maintain unprecedented visibility & control of enterprise data on endpoint user devices including BYODs.
Secure Data

Circle for Privacy Assurance

Avoid costly compliance and possible liabilities by letting users securely store their personal data on endpoint devices and share that information using zero knowledge encryption
Communicate and collaborate with complete privacy without the leakage of user identity, activity or even metadata
Never lose access to private data using Circle's breakthrough Circle-of-Trust social authentication technology
Secure Privacy
