Only collect data you actually use. Mask sensitive fields in admin views, and remove personally identifiable information from logs, analytics, and error screenshots. Document data flows between tools so you see where copies accumulate. Offer easy deletion and export options to build trust. Cache minimally and expire aggressively. A founder handling coaching notes won users by guaranteeing private projects stayed isolated, limiting staff access, and demonstrating a simple redaction process during demos. Respect builds momentum and referrals without extra marketing spend.
Create separate service accounts for production, staging, and personal experiments. Store secrets in the platform’s vault or a trusted manager, never inside notes or description fields. Revoke access when contractors leave, and audit permissions monthly. Use granular roles that prevent accidental schema edits. For external APIs, scope tokens to only needed endpoints, and rotate them with calendar reminders. An early mishap I witnessed involved a shared token pasted into a tutorial. Rotation policies and private variables would have prevented the scare entirely.
If you touch health, finance, or education data, ask vendors for security documentation, certifications such as SOC 2, ISO 27001, or HIPAA‑aligned features, and clear data processing agreements. Clarify data residency and subprocessors. Check audit logs, SSO options, and webhooks security. Even if full compliance is not required yet, aligning with best practices early reduces costly rework. Start a lightweight register of third‑party tools and data categories so investors and enterprise customers see diligence, not improvisation, when due diligence begins.
