Alexandru Caciulescu is a Cloud Security Advisor with 12 years of experience designing SOC architectures, enterprise security programs, and multi-cloud governance across Azure and AWS. He builds scalable control frameworks and security-as-code enforcement models, having led an enterprise-wide Wiz deployment spanning 50+ Azure subscriptions and 100+ AWS accounts. Alexandru combines hands-on DevOps and detection engineering experience—having contributed to open-source projects like radare2 and the D standard library—with strategic advisory work that translates business risk into secure-by-design architectures. He has a proven track record of maturing SOC capabilities, automating incident response, and shaping IAM architectures for large-scale cloud estates. Based in Bucharest, he pairs technical depth in tooling and code with program-level leadership, often partnering with enterprise architecture and engineering to operationalize zero-trust principles. An unexpected thread through his career is active low-level engineering work (reverse-engineering tooling and language runtime contributions) that informs his pragmatic, developer-friendly security designs.
