Top SchoolOlly Ewert is a Lead Security Architect with 15 years’ experience helping teams "shift left" on security so they can deliver faster and with greater confidence.

Known for automating security controls and integrating detection/remediation into CI/CD pipelines, he’s worked across finance, consulting and product organisations and contributes to open source. An IAM specialist and platform security generalist who also codes in Python and Go, Olly pairs deep technical troubleshooting with a knack for teaching and pragmatic process change.
