Pedro De Castro is a hands-on security engineer and technology leader with a decade of experience building scalable EDR and SIEM products and teams from the ground up. As an early and founding engineer of Wazuh who later scaled the organization to ~100 engineers and served as CTO, he blends deep low-level development (C, Python, NodeJS) with product, infra and SaaS architecture expertise on AWS. He has designed and shipped core modules—vulnerability detection, file integrity monitoring, policy assessment—and led the creation of Wazuh’s SaaS and Open Source platform used for massive alert volumes. Pedro pairs technical leadership with customer-facing roles in pre/post-sales and compliance (PCI DSS), and contributes to the flagship Wazuh repo (notably Windows agent installer improvements) and its documentation. Now focused on driving community success and AI-powered support workflows, he’s known for pragmatic execution, cross-functional team-building, and a developer-first management style.
