SAN ANTONIO, TX — June 16, 2025 — San Antonio Cyber Defense, a fast-growing provider of enterprise cybersecurity solutions, announced today it has closed a $12 million Series A funding round led by Austin-based venture firm Lone Star Ventures, with participation from CrowdStrike's strategic investment arm and several prominent angel investors. The company plans to deploy the capital across three primary initiatives: expanding its proprietary ThreatWatch AI platform, growing its engineering and security operations workforce by approximately 40 employees over the next 18 months, and accelerating sales efforts into federal government and critical infrastructure markets. "This funding validates what our clients already know — that mid-market organizations and government agencies deserve enterprise-grade protection without enterprise-grade complexity," said CEO Maria Delgado. "We built ThreatWatch to close that gap, and this investment allows us to reach the organizations that need it most." Founded in 2021, San Antonio Cyber Defense has grown to serve more than 180 clients across Texas and the broader Southwest, reporting 140% year-over-year revenue growth in 2024. The company currently monitors more than 2.3 million endpoints daily across its customer base. The raise comes amid sustained demand for managed threat detection services, as cyberattacks against municipal governments and energy infrastructure continue to increase nationwide. **About San Antonio Cyber Defense** San Antonio Cyber Defense is a Texas-based cybersecurity firm specializing in AI-powered threat detection, managed security services, and incident response for mid-market enterprises and public sector organizations.
