Case Study: Robert rebuilds a breached marketplace into a secure, scalable app with Appinventiv

Robert rebuilds a breached marketplace with Appinventiv and cuts 47 critical vulnerabilities to 3 low-risk issues

The customer, a solo entrepreneur, built a peer-to-peer marketplace for vintage collectibles using AI-assisted vibe coding tools. After a cyberattack exploited severe security flaws in the app, resulting in a data breach and financial loss, the entrepreneur engaged Appinventiv for cybersecurity solutions, including an app security audit and DevSecOps services.

Appinventiv performed a forensic audit and completely rebuilt the application with a zero-trust architecture, encryption, and secure payment flows. Post-relaunch, the platform saw a 94% reduction in vulnerabilities and no further security incidents. This allowed the business to grow significantly, achieving a 3.2x increase in users and raising monthly gross merchandise value from ~$38,000 to $240,000 within six months.
