Security Is a System Property. Privacy Is an Architectural Decision.

Mythos Systems does not claim that every product is fully local, cloud-free, zero telemetry, post-quantum secure, or compliant with every framework. Each product must define its own scope.

Security Domains

  • Identity & Access

    Authentication, authorization, object-level access, and audit.

  • Secrets & Encryption

    Secrets management, encryption, update integrity, and supply chain.

  • Sandboxing

    Dependency trust, sandboxing, data classification, backup, and recovery.

  • Model Permissions

    Model permissions, tool permissions, and monitoring.

Privacy Domains

Privacy design may include data minimization, local processing, browser-local processing, private storage, explicit consent, limited retention, user deletion, scoped telemetry, and clear third-party disclosure.

Sovereignty means users retain meaningful control over where data lives, which model processes it, which tools may act, what is synchronized, what leaves the device, and how it can be exported or deleted.

Local-First

Local-first is appropriate where sensitive data is involved, offline use matters, native access matters, user ownership matters, and hosted dependency should be optional.

Product Scope

A hosted service can still support sovereignty if its boundaries are explicit and user-controlled. The PANTHEON private browser (Perseus) explores privacy-first browser architecture. AEON applies conservative AI boundaries to private life records. PANTHEON defines agent and tool authorization for engineering environments.
