Security & Procurement FAQ

Does SignAndGo have security certifications?
SignAndGo is designed with security controls aligned to industry standards. We are working toward formal certifications including SOC 2 Type II and ISO 27001. Contact us for our current security documentation.
Where is data stored?
All data is stored in Google Cloud Platform Sydney (australia-southeast1) with a managed database providing Australian data residency. Documents are stored in secure cloud storage with server-side encryption. All infrastructure is provisioned within Australian regions.
How is data encrypted?
Data is encrypted in transit using TLS 1.2+ and at rest using AES-256. Signing tokens are stored as cryptographic hashes. API communications use HTTPS exclusively.
What authentication methods are supported?
SignAndGo supports email/password sign-in plus Google and Microsoft single sign-on via OAuth 2.0. Passwordless magic link sign-in is also available, and any account can enable two-factor authentication (TOTP). Authenticated sessions use short-lived tokens with an idle timeout that workspace admins can configure, and re-authentication on expiry.
How do you handle data retention?
Data retention policies can be configured per workspace. Completed documents and audit trails are retained according to your policy requirements. We support data export for compliance purposes.
Can we get a security questionnaire or your security documentation?
Yes. We can complete security questionnaires (SIG Lite, CAIQ), share a summary of our internal security reviews, and provide other security documentation under NDA. Contact us at sign@signandgo.com.au.
Is SignAndGo GDPR compliant?
Yes. We provide data processing agreements (DPA), support data subject rights, and maintain records of processing activities. See our DPA Summary page for details.
What happens if there is a security incident?
We have an incident response plan that includes containment, investigation, notification, and remediation phases. Customers are notified promptly of incidents affecting their data as required by applicable regulations.
