Critical and high findings resolved

How to Harden an AI-Coded App: The Hardening Sprint

We implement the critical and high-severity findings from your Vibe Code Audit. Secrets management, authentication, input validation, CORS, API security, environment separation. Scope confirmed before work begins.

A Hardening Sprint implements the Critical and High security findings from a Vibe Code Audit: secrets migration, authentication hardening, input validation, CORS and API security, and environment separation. It costs $4,500–$8,000 flat, with scope and price confirmed before work begins, and typically delivers in 5–10 business days.

What’s included

$4,500–$8,000 flat

Remediation of all Critical findings from the Audit
Remediation of all High findings from the Audit
Secrets migration: hardcoded credentials moved to environment variables or a secrets manager
Authentication hardening: server-side session management and route protection
Input validation implementation across identified attack surfaces
CORS and API security configuration
Environment separation: dev, staging, and production properly isolated
Post-implementation verification: we re-run the Audit checklist on the patched codebase
Updated report showing finding status: resolved, partially resolved, or deferred

Scope a Hardening Sprint

What’s not included

The Hardening Sprint implements fixes for security findings. It does not include new feature development, database migration to a production-grade system, or backend infrastructure build. If those are needed, they are scoped as a Backend Build engagement.

Pricing

$4,500 for applications with a straightforward finding set, typically fewer than 10 critical/high findings, standard auth surface, no complex third-party integrations.

$5,500–$8,000 for more complex finding sets. Exact price confirmed after Audit delivery, before Sprint work begins.

The Audit fee is credited in full toward the Sprint when booked within 30 days of Audit delivery.

Timeline

Scope and price confirmation: within 48 hours of Audit delivery. Sprint delivery: 5–10 business days depending on finding complexity. Post-implementation verification: delivered with the Sprint.

Common questions

Straight answers before you book.

Do I need a Vibe Code Audit before a Hardening Sprint?

Yes. The Hardening Sprint implements the Critical and High findings documented in a Vibe Code Audit. Without the audit there is no scoped, prioritized finding set to implement. If you proceed to a Sprint within 30 days of your audit, the audit fee is credited in full toward the sprint.

How long does a Hardening Sprint take?

Typically 5–10 business days depending on the number and complexity of findings. Scope and price are confirmed within 48 hours of audit delivery, before any sprint work begins. There is no open-ended billing.

Does the Hardening Sprint fix every finding?

It resolves every Critical and High finding. Medium and Low findings are documented with remediation guidance for your team to implement later. They are real issues, but none are exploitable without first bypassing the hardened authentication layer.

Will hardening break my existing app or UI?

No. Hardening changes how the app handles secrets, authentication, input, and environments, not the user-facing UI. In our case study, a solo founder's client portal went through an audit and hardening sprint with zero lines of UI rebuilt.
