Offer 02

Firebase Security Rules Audit + Fix PR

Apps built quickly on Firebase often ship with rules that let one signed-in user read or edit another customer’s data. This audit tests whether yours does, and fixes what it finds.

$950
fixed price, 5 business days

Scope

  • Firestore and Storage rules, plus up to 15 Cloud Functions, in one Firebase project

You get

  • A written role and tenant access model
  • An emulator test suite that tries cross-user reads and writes, cross-tenant reads and writes, and role escalation
  • A report ranked by severity
  • A pull request with rule fixes that passes the suite

Not included

  • Compliance certification
  • Infrastructure outside Firebase
  • App refactors

Delivery

5 business days.

Everything runs on the emulator or test data only, never your production records.

This is a technical review, not a compliance certificate.
