Stay Secure Without Disrupting AI Innovation

The use of ML Models without security checks puts your enterprise at risk. ML Models can contain malicious code and then be downloaded and deployed in your environment, with no policy or controls in place to scan for hidden risks that can be exploited by internal and external cybersecurity criminals. 

Guardian continuously scans both third and first party models for security threats, before the model is utilized. This adds a critical layer of security to ML model development and deployment, so you can continue AI exploration and innovation with confidence. 

Enforce Model Security

AppSec teams can protect against threats with enterprise wide policies to enforce the use of secure models within the organization and improve security posture.

Ease of Integration

It integrates easily with existing MLOps workflows, to keep pace with AI driven innovation.

Comprehensive Model Scanning

Guardian goes beyond traditional malware scanning tools and detects malicious code in ML models early in development and deployment.
