Next-Generation Hardware Security for the Zero-Trust Era
The CoreTrust Key is a hardware-based FIDO2 security key designed to protect digital identities and prevent unauthorized access in today’s evolving cyber threat landscape. By enabling passwordless authentication, it eliminates the risks associated with traditional passwords, such as phishing and credential theft, while strengthening Zero-Trust security frameworks.
Works Across Your Daily Platforms
The CoreTrust Key enables secure passwordless login across widely used platforms and services, including Google, Microsoft, social media, and e-commerce applications. With a single USB key, users can securely access their accounts and services without relying on passwords, providing a safer and more convenient authentication experience.
Passwordless Authentication with Seamless Deployment
Supporting the FIDO2 standard, the CoreTrust Key allows users to authenticate securely without changing existing systems or workflows. Its plug-and-use design makes it easy to deploy across both personal and enterprise environments, delivering strong security with minimal user effort.

Secure Access for Modern IT Environments
Designed for both individuals and organizations, the CoreTrust Key enhances secure access to cloud services, corporate systems, and critical resources. It is an ideal solution for enterprises adopting Zero-Trust architectures, ensuring that only verified users can access sensitive systems and data.
PUF-Based Hardware Security Protection
The CoreTrust Key incorporates advanced PUF (Physical Unclonable Function) technology to generate a unique and unclonable hardware identity for each device. This provides strong protection against cloning and physical tampering, ensuring a high level of trust and security for authentication processes.
Enterprise-Ready Security Integration
The CoreTrust Key can be integrated into enterprise IT infrastructures to strengthen identity verification and access control. When deployed alongside security solutions such as Zero Trust gateways, it helps organizations build a more secure and reliable network environment.
Secure, Portable, and Easy to Use
With its compact USB form factor and durable design, the CoreTrust Key offers a portable and user-friendly solution for everyday authentication. It provides strong security protection while maintaining a simple and intuitive user experience.

Secure Access Across Daily Platforms and Enterprise Environments
The CoreTrust Key enables secure passwordless access across widely used platforms such as Google and Microsoft, while extending strong identity protection to enterprise systems and critical network resources. When deployed with PLANET solutions such as the ZT-800 Zero Trust Gateway, it helps enforce secure access control and ensures that only authenticated users can access sensitive services and infrastructure.
