• Integration with AI Mentor Studio API: Enables REST access to code analysis metrics, technical debt levels, and automatic reports on module quality.

Thanks to this open architecture, OutSystems allows SMEs to integrate their applications with existing enterprise systems, scale their data flows, and maintain total control over security, performance, and governance.

Security and Data Compliance

OutSystems was designed under the principle of “built-in security from development.” Each application created automatically inherits the platform’s security policies and controls.

• Comprehensive protection: Encrypts all data in transit and at rest, and incorporates multi-step verification and role-based access control.
• Global regulatory compliance: Certified in ISO 27017 and 27018, SOC 2, GDPR, PCI DSS, and CSA STAR, ensuring enterprise standards in regulated sectors like banking, healthcare, or public services.
• AppShield for mobile: Add-on that reinforces native app security against reverse engineering, malicious code, or compromised devices, adding protection layers without requiring additional programming.
• Audits and automated DevSecOps: Each deployment cycle executes integrity validations, vulnerability analysis, and quality controls before publishing to production.
• Ownership and privacy: Data and applications always belong to the client. Environments are isolated by organization and protected with tenant-specific encryption keys.

This architecture reduces risks, complies with the most demanding regulations, and provides SMEs with the same security used by large corporations.

Language – Customer Support and Interface

The interface and documentation are available in English. It doesn’t have direct support in other languages, though there are certified partners in various regions offering assistance and training in local languages.

AI Language – The Tool Itself

OutSystems’ artificial intelligence, Mentor, wasn’t specifically trained in multiple languages; its primary focus isn’t conversational but structural, so it can generate code and models without depending on the user’s language.

Created applications can be completely translated to multiple languages through Service Studio’s multilingual editor, which supports RFC 1766 locales (e.g., en-US, fr-FR, de-DE).

Mobile Access
