Founder of Defenzar
Alexander Prezioso is the Founder of Defenzar, a cybersecurity risk intelligence platform that helps organizations understand and reduce their digital exposure before attackers exploit it.
A military veteran with 31 years of service in the United States Army, Alexander brings a deep-rooted commitment to security, leadership, and mission-focused execution to everything he builds.
With a background in enterprise mobile development and cybersecurity, Alexander has spent years working on large-scale, mission-critical systems where security, trust, and reliability are essential. His experience spans environments where protecting people, data, and infrastructure is critical to operational success.
Alexander founded Defenzar after recognizing a major gap in cybersecurity visibility for many organizations. While cyber threats continue to evolve rapidly, many businesses lack a clear understanding of their external security exposure until a problem occurs.
Defenzar was created to address this challenge by providing organizations with clear, actionable insights into their cyber risk posture, allowing them to identify vulnerabilities early and strengthen their defenses.
Under his leadership, Defenzar focuses on delivering practical cybersecurity intelligence that helps businesses make informed security decisions and better protect their digital assets.
