Optimal’s information system and infrastructure is independently certified to ISO/IEC 27001 and ISO/IEC 27701, and is SOC 2 Type II audited. Data is encrypted in transit (TLS 1.2) and at rest (AES-256), the platform supports SSO via SAML 2.0, and independent penetration testing is carried out annually.

Optimal follows the WCAG 2.1 AA guidelines across the platform, prioritising accessible participant experiences like keyboard navigation, screen-reader support, visual accessibility and mobile. However, some methods are visual by nature. First-click and prototype testing ask participants to view and click on an image, so they can't be made fully accessible to people who rely on screen readers since the task itself depends on seeing the design. Where that matters for a study, teams can choose methods that don't carry the same constraint. Full detail is in our Accessibility Statement.

All Optimal plans include unlimited seats, so the whole team and its stakeholders can access research.
