Security & Compliance FAQ

Q: Does Averoia store employee email messages?

Never. Under our strict Zero Message Storage architecture, outgoing emails are enriched in volatile memory and returned to Microsoft 365 in under 15ms. Email contents never touch persistent disk storage.

Q: How do we execute a Data Processing Agreement (DPA)?

Directly within your customer console. The Article 28 DPA is available digitally for immediate execution and PDF export.

Q: Can Averoia pass an enterprise cybersecurity audit?

Yes. We supply comprehensive architecture documentation, TOMs, and penetration testing summaries to satisfy enterprise infosec teams.

Q: What occurs in the event of an infrastructure outage (Fail-Open)?

Should an endpoint be momentarily unreachable, Exchange Online transport rules bypass the connector and deliver messages directly, guaranteeing zero mail loss.
