About Polymer

Polymer sells a platform to identify, analyze, and mitigate real-time security risks across AI and SaaS ecosystems. Polymer describes the problem as one where AI agents work alongside employees in the tools they use every day.[1][2]

Polymer secures data the moment AI or humans generate or access it. Polymer lets organizations create and manage context-driven security policies tailored to their own requirements and AI usage. Polymer groups human and non-human identities to control how they can interact with data.[1][2]

Polymer monitors data in motion and at rest based on custom security policies. Polymer provides reports and risk scores that expose vulnerabilities such as shadow AI usage, insider threats, and misconfiguration. Polymer remediates violations at runtime by redacting sensitive data, revoking file access, and triggering custom workflows with or without human review.[2]

Polymer generates audit logs mapped to regulatory frameworks such as HIPAA, SOC 2, CCPA, and GDPR. Polymer includes role-based access controls (RBAC) and is SOC 2 Type II compliant.[1][2]
