Summary
👤
Senior🎓
Top SchoolThomas Leplus is an executive security leader with 13+ years of experience securing complex financial platforms and a background that spans hands-on software engineering to strategic security leadership. He has led product and application security programs at Adenza, Nasdaq, Calypso and now Capital Fund Management, building automation-driven reporting, cloud abstraction layers, and security champion programs to scale secure releases for regulated customers. Thomas combines deep application security expertise (SAST/DAST/SCA, API and multitenancy protections, OWASP/CWE practices) with operational rigor in audits, SOC2 and ISO engagements, and customer-facing remediation SLAs. He is adept at translating developer workflows into secure CI/CD pipelines and crafting out-of-the-box integrations for cloud IAM, logging and secret management. Notably, he designed a CI/CD-driven KPI reporting system that gave leadership and customers near-real-time visibility into vulnerability status and remediation ETAs. Based in France, he pairs an MSc in Computer Science with a rare mix of engineering pedigree and security program-building across global trading and risk platforms.
