Yeray Lafontaine.
IT and Cloud Security Engineer.

I am an IT and Cloud Security Engineer based in Puerto Rico. Lafontaine Security LLC is my independent consulting practice, built to bring real security work to organizations that need it without the overhead of a large firm.

My background is operational. I have served as the sole IT and security owner for a multi-site healthcare organization, responsible for every security domain at once with no team and no escalation path. Real architecture decisions under real constraints. Governance documentation that holds up under audit. Incident response capability built from zero.

I specialize in Microsoft 365 Business Premium environments and understand the licensing boundaries that most small and mid-size healthcare organizations actually operate within. I do not recommend enterprise tooling to organizations that cannot afford to run it.

I am currently pursuing a B.S. in Cybersecurity and Information Assurance at Western Governors University and previously held a U.S. Secret Clearance.

If your organization needs a security program built correctly and not just checked off, I am available for project-based engagements and monthly retainers.
