Security Hardening
AI built your app. Who checked the security?
Your AI-built application is crossing from experiment to something that matters. Real users, real data, real business processes. Have someone experienced look for the obvious holes first.
Sound familiar?
The application has become too valuable to leave unreviewed.
- Customers are about to use it. Or already are.
- Sensitive data is entering the system.
- Payments or financial workflows are involved.
- A customer or partner has asked security questions you can't confidently answer.
- Nobody has seriously reviewed what the AI actually generated.
- You know authentication and access control exist, but you're not sure they're right.
- The application connects to internal systems or third-party APIs with real credentials.
AI makes it possible to build impressive software quickly. It also makes it possible to ship things the builder doesn't fully understand. A six-month security program is overkill for most of these situations. What helps is an experienced engineer who can find consequential problems, fix what can be fixed, and establish a sensible production deployment.
What happens
Practical security hardening
I review the application for consequential security issues and fix what matters. The output is working code, not just a report.
- Review authentication, authorization, and access control
- Check API exposure, injection vulnerabilities, and data handling
- Assess secrets management, database exposure, and tenant isolation
- Review cloud/IAM configuration and network security
- Fix the important issues directly in the codebase
- Establish a sensible secure production deployment
- Document what was found, what was fixed, and what to watch for
After the engagement
What changes
- You know what security risks actually matter in your application.
- The important holes are actually fixed, in the code.
- The application is deployed in a sensible secure production setup.
- You can answer customer security questions with confidence.
- You have a clear picture of what's solid and what needs attention over time.
Who this is for
AI-built applications approaching serious production use, with real users, real data, or real business processes depending on them.
Engineering security hardening. If you need a formal penetration test, audit, or compliance certification, that's a different engagement.
