Security hardening implementation

1.4–3.8 weeks typical Fixed quote after scoping

The security review's implementation counterpart: secrets lifecycle, rate limiting, bot protection, webhook authentication, and session hardening — done, not just recommended.

What we build

Fixing the security findings rather than filing them: the implementation counterpart to our security hardening review. We move secrets into managed storage with a rotation routine and CI scanning that stops keys ever reaching the repository; add rate limits and abuse caps so one bad actor can't run up your bill; roll out bot protection in monitor-then-enforce stages so real users are never locked out by mistake; authenticate every webhook with timing-safe signature checks and replay windows; and harden sessions and service-to-service access. Choose the review when you need to know where you're exposed; choose this when you already know — from our review or anyone's — and want it closed. Sign-in, sessions and identity modelling belong to authentication & identity integration.

What you get

  • Every secret moved into managed secret storage, with the repository scanned clean
  • A documented rotation procedure, executed once
  • Secret scanning running on every CI build
  • Rate limits enforced on every public endpoint, with a test proving requests over the limit are rejected
  • Service-to-service calls restricted to authenticated workloads

How the work unfolds

  1. Move secrets into managed storage with rotation
  2. Add secret scanning to CI
  3. Implement rate limiting and abuse caps
  4. Roll out bot protection monitor-then-enforce
  5. Authenticate webhooks with replay protection
  6. Harden service-to-service access
  7. Implement data retention, export and deletion requests

What shapes the price

Before you see a number, our scoping conversation asks:

  • Is the product exposed to bots and scripted abuse — public sign-up, a free tier, anything scrapeable? Bot protection rolls out monitor-first and is wasted on invite-only products.
  • Does the system receive webhooks from providers like Stripe or Slack? Webhook authentication with replay protection only matters if webhooks arrive.
  • Do deletion and data-export requests need to be built into the product, or are they handled manually for now? Retention/export/deletion tooling is up to a week; early products handle requests by hand.

How an engagement starts

This work builds on Discovery workshop, so scope, boundaries and constraints are agreed before anything is built.
