Yappo Security LLC

Yappo CyberSec is a next-generation penetration testing company focused on fast, clear, and affordable security assessments for startups and small companies.

We specialize in AI-Driven Web & API Penetration Testing, combining automated intelligence with deep manual analysis to deliver practical, high-impact findings that teams can fix quickly. Every engagement is human-led and designed for modern online products.

Our offering includes multiple pentest levels plus optional add-ons for LLM Security Checks (prompt injection, data leakage, unsafe actions) and Mobile App Spot-Checks (Android/iOS).

All results are delivered through our own SaaS reporting platform, providing a clean experience with clear evidence, severity, recommendations, and retests to validate fixes.

We work with agile teams, SaaS products and early-stage companies that need a professional pentest without enterprise complexity.

Our goal is simple: help you understand your real security risks and fix them before they matter.

We invite you to review the Upwork work history of our Business Owner, Emanuel Parraga, or our Agency Profile to see feedback from our satisfied clients. We're eager to bring our skills and expertise to your cybersecurity efforts.
