Your Data,
Protected by Default
Enterprise-grade encryption, GDPR-aligned practices, and zero data sharing. Security is built in, not bolted on.
AES-256 Encryption
All survey data is encrypted at rest and in transit using AES-256, the same encryption standard used by financial institutions and government agencies. Your respondents' answers are protected from the moment they submit.
Secure Authentication
Industry-standard authentication with hashed passwords, secure session management, and optional OAuth via Google and Microsoft. Rate-limited login to prevent brute force attacks.
GDPR Compliance
GDPR-aligned data handling is built into every plan. We process data lawfully, collect only what's needed, and give respondents control over their information.
Zero Data Sharing
Your respondents' data is never sold, shared with third parties, or used for advertising. Data belongs to you and your organization exclusively.
Content Security Policy
Strict CSP headers with nonce-based script execution prevent cross-site scripting (XSS) and injection attacks. HSTS enforced for all connections.

Why Enterprise-Grade Security Matters for Surveys
Surveys collect some of the most sensitive data in your organization: employee satisfaction scores, customer health metrics, patient feedback, and financial opinions. A breach of survey data can be as damaging as a breach of your CRM or HR system, yet many teams treat survey security as an afterthought. SurveyFill is designed so that you never have to think about it—every security control is on by default, on every plan, with no configuration required.
For organizations subject to regulatory requirements, the details matter. SOC 2 Trust Service Criteria demand that you can demonstrate how data is encrypted, who has access, and what happens when an incident occurs. ISO 27001 requires a formal information security management system with documented risk assessments and controls. SurveyFill's architecture is built around these frameworks, so when your auditors ask about survey data handling, you have answers ready.
Security also means protecting data from internal misuse. Role-based access control ensures that team members only see the surveys and responses they are authorized to view. Every action—login, data export, survey edit, member invitation—is logged with user attribution and timestamps. These audit trails are available to organization owners and can be exported for compliance reporting.
