Enterprise-grade security.
Engineered from day one.

Enterprise security built on four pillars: military-grade encryption, isolated cloud environments, secure AI processing, and regulatory readiness.

Overstand is built for organizations that can't compromise on data security.

Built by professionals with nearly a decade of experience in the privacy space — having worked with GDPR in Europe, CCPA in California, financial data in Switzerland, and U.S. and European healthcare regulations during the COVID-19 pandemic and beyond.

Four pillars of data security

Every layer of Overstand is designed to keep your sensitive communications data under your control.

Pillar 1

Military-grade encryption at every layer

Your data is protected with the same encryption standard trusted by governments and financial institutions worldwide.

  • AES-256 encryption — the gold standard for data at rest
  • Per-chunk encryption keys — each data segment gets its own unique key
  • TLS 1.3 in transit — all data encrypted during transfer
  • Automatic key rotation — keys are rotated on a regular schedule

Each chunk encrypted with a unique AES-256 key

Customer A — Isolation Boundary

User Derived Data
No data crossover

Customer B — Isolation Boundary

User Derived Data

Pillar 2

Isolated cloud environments for every customer

Every customer's data is isolated at the storage level — both the initial raw data you bring in and any derived data created by users. Data never crosses between environments, and derived data is marked with mandatory controls so that nobody unauthorized can access it.

  • Filesystem-level isolation — raw data and derived data are stored in completely separate environments per customer
  • No data crossover — your data never touches another customer's environment
  • Mandatory access controls — derived data is tagged so unauthorized users can never reach it

Pillar 3

Secure AI processing

By default, Overstand uses secure, stateless endpoints backed by agreements with major model providers — your data is never stored or used for training. If you prefer full control, you can optionally bring your own API keys.

  • Stateless endpoints — secure connections to major model providers with zero data retention
  • Optional BYO keys — connect your own OpenAI, Anthropic, or Azure OpenAI keys for full control
  • Full audit trail — every prompt and response is logged for compliance review

Pillar 4

CCPA / GDPR / HIPAA Ready

CCPA Ready

Infrastructure designed to meet California Consumer Privacy Act requirements, including data access, deletion, and opt-out mechanisms.

GDPR Ready

Infrastructure designed to meet General Data Protection Regulation requirements, including data portability and right to erasure.

HIPAA Ready

Infrastructure designed to meet HIPAA requirements, including encryption, access controls, audit trails, and Business Associate Agreement support.

Additional security practices

Beyond the four pillars, every layer of Overstand is built with security-first principles.

Role-Based Access Control

Granular permissions ensure users only access the data and features relevant to their role.

Audit Logging

Immutable logs of every query, export, and administrative action with full user attribution and timestamps.

No Training on Your Data

We never use your data to train AI models. Your data exists solely to serve your organization.

Secure Integrations

All third-party integrations use OAuth 2.0, encrypted credentials, and least-privilege access scopes.
