Alejandro Aucestovar

Alejandro Aucestovar is a cybersecurity architect focused on DevSecOps, cloud security, and AI/LLM application security. He holds a Master’s degree in Information Security Engineering from SANS and specializes in building practical security solutions that integrate directly into CI/CD pipelines. His work centers on identifying and validating real-world risks in modern cloud environments, particularly around prompt injection, data exfiltration, and software supply chain exposure.

Rather than relying on theoretical controls, Alejandro focuses on testing and breaking systems early in the development lifecycle to ensure defenses actually hold up under realistic conditions. His approach emphasizes closing the gap between security design and engineering execution, with a focus on scalable, repeatable patterns that security teams can apply without slowing development.
