Optimize your compliance budget

Formal audits bill by the hour. Every finding extends the engagement. Remediate first, certify fast.

Cut Compliance Costs

CREST-accredited pen-tests charge premium rates for every finding. Pre-fix your Firestore rules and auth misconfigs—pay only for advanced testing, not documentation of known gaps.

Built for Firebase from the ground up

We don't run generic vulnerability scans. Our assessments are purpose-built for Firebase's unique architecture—from security rules to callable functions to real-time database access patterns.

/users/{userId}/private
Issue
Missing request.auth.uid == userId check allows any authenticated user to read private documents.
Copy-Paste Fix

  allow read: if request.auth != null
    && request.auth.uid == userId;
}

Everything you need to pass clean

A complete Firebase pre-audit package with findings your team can actually act on.

01

Security Rules Deep Dive

Line-by-line analysis of your Firestore, Storage, and Realtime Database rules. We identify overly permissive patterns, missing auth checks, and data exposure risks.

  • Wildcard collection vulnerabilities
  • Cross-user data access paths
  • Write validation bypass patterns
02

Cloud Functions Audit

Security review of your callable, HTTP, and triggered functions. We test for injection, auth bypass, privilege escalation, and insecure environment handling.

  • Callable function auth validation
  • Admin SDK privilege escalation
  • Secrets and env var exposure
03

Authentication Config Review

Evaluate your Firebase Auth setup for weak configurations, enumeration risks, and OAuth misconfigurations that auditors consistently flag.

  • Email enumeration prevention
  • OAuth provider hardening
  • Custom claims validation
04

Engineering-Ready Remediation Guide

This is the difference. No vague recommendations—each finding comes with exact security rules, function patches, and config changes your engineers can deploy directly.

firestore.rules
1 // Finding: Unrestricted admin collection access
2 // Risk: CRITICAL | Framework: SOC 2 CC6.1
3
4 match /admin/{document=*} {
5   allow read, write: if isAdmin();
6 }
7
8 function isAdmin() {
9   return request.auth.token.admin == true;
10 }

Firebase teams that passed clean

See how engineering leaders used pre-audit to eliminate surprise findings.

"Our Firestore rules were a mess from two years of rapid iteration. They found 12 cross-user data leaks we had no idea existed. All fixed before the auditors even scheduled their first call."

Michael K.
VP Engineering, Series B Fintech

"The remediation guide was incredible. Actual security rules we could copy-paste. Our devs fixed 23 issues in two days instead of the usual two weeks of researching Firebase docs."

SR
Sarah R.
CISO, Healthcare SaaS

"We budgeted $180K for our SOC 2 pen-test based on last year. After pre-audit remediation, the formal test came in at $62K. They literally found nothing significant in our Firebase infrastructure."
