Mailpro protects survey data on three levels: in transit (SSL/TLS), at rest (encrypted Swiss-hosted databases) and at access (passwords, CAPTCHA, granular user permissions). The combination keeps both the respondent’s answers and your account’s aggregate data away from anyone who shouldn’t see them.
The pillars of survey security
Every response travels over an encrypted connection — see SSL encryption. Sensitive surveys can be locked behind a password, and a CAPTCHA stops bots from skewing your data. On your side, granular user permissions control who in your team can view, edit or export results, and EU-based hosting plus full data export and deletion on request keep you GDPR-aligned.
Best practices on your side
Even with strong infrastructure, sensitive surveys benefit from extra hygiene: avoid asking for data you don’t actually need, anonymize at collection when possible, and remove old responses you no longer use. Also, don’t share the survey link in public channels if it contains personal questions.
