Privacy vs. Security: What’s the Difference (and Why It Matters for Compliance)

Privacy and security are related, but they’re not the same thing.

Privacy is about how personal information is handled: what you collect, why you collect it, how you use it, who you share it with, how long you keep it, and what rights people have.

Security is about protecting systems and data from unauthorized access, misuse, loss, and disruption.

Why the difference matters for compliance

A lot of teams try to “do compliance” by buying security tools. That helps, but it doesn’t finish the job.

You can have strong security and still fail privacy if:

  • you collect more data than you need
  • your consent and disclosures are vague
  • you keep data indefinitely “just in case”
  • you share data with vendors without clear boundaries
  • you can’t answer “what data do we have on this person”

And you can have privacy policies and still fail in practice if:

  • access control is messy
  • there’s no monitoring
  • there’s no incident response plan
  • cloud configuration is risky
  • vendor access is uncontrolled

Compliance expectations usually require both: privacy governance and security safeguards.

A simple self-check: who, why, how, how safe

If you want a quick internal test, use this:

  • Who: whose data is it, and who can access it
  • Why: what’s the purpose, and is it necessary
  • How: how is it collected, used, shared, and retained
  • How safe: what prevents exposure, misuse, or downtime

If your team can’t answer these clearly, you don’t have a program yet. You have vibes.

What to do first for most small teams

If you’re early-stage or small, start with the highest-ROI foundations:

  • Assign ownership (someone has to own the decisions)
  • Map data and vendors (you can’t protect what you can’t see)
  • Tighten access (MFA, least privilege, clean offboarding)
  • Add retention rules and incident response basics

That’s exactly what Minimum Viable Privacy (MVP)

is designed to cover.
