Startup Security Baseline

The minimum security an early startup needs before customers trust it with data.

Also known as: security baseline, startup security, minimum security

A startup security baseline is the minimum that lets customers trust you with their data: encrypted transport and storage, secrets out of code, patched systems, access control with leavers revoked, backups tested, and logging that would show what happened. Not compliance-grade — just the obvious things done before the first enterprise questionnaire arrives.

baseline:  HTTPS everywhere · secrets in a manager · auto-updates on · MFA on everything
           · least-privilege access · offsite tested backups · audit log of who did what

Do it early because retrofitting under a customer’s deadline costs ten times more, and because the first breach (or the first lost laptop with production keys) is an existential event at startup scale. None of this requires a security team — it requires an afternoon and a checklist.

The classic mistakes:

Secrets in code and chat. API keys in repos, passwords in Slack — the most common breach vector and the easiest to fix with a secrets manager and a pre-commit hook (see secrets management).
Everyone is admin. Shared root credentials and permanent broad access mean a departure or phish compromises everything. Least privilege plus prompt deprovisioning.
Untested backups. Backups that never restored are hope, not safety. Restore-test quarterly — the drill that finds the broken backup before the outage does.
Security questionnaires answered aspirationally. Claiming controls you lack to win a deal creates liability and a mad scramble later. Answer honestly, commit dates for gaps, and close them.
Ignoring the human layer. Phishing beats firewalls at startups. MFA everywhere, suspicious-link culture, and a clear “who to tell” path matter more than another tool.

Grow into: formal policies, SOC 2 when enterprise deals demand it, and a security review per major release. The baseline buys the right to reach that stage.
