I’m Harold Briceño, a cloud identity and security specialist living in Santiago, Chile, originally from Venezuela.
I’ve spent 15+ years keeping technology running for companies in Venezuela and Chile. I started in hands-on support, moved into systems administration, and today I run Microsoft 365, Entra ID, and Azure at enterprise scale. Identity, security, and cloud governance are what I do.
Over the years the pattern behind almost every incident I resolved became obvious: things break where nobody is looking. The dormant account of an ex-employee. The share that was opened “just for now.” The MFA rollout that covered everyone except the three accounts that mattered. So I ended up building that watch myself: automation with PowerShell, Microsoft Graph, and AI that checks the boring but critical things every day, before they turn into an emergency.
What I’m doing now
- Administering Microsoft cloud environments (M365, Entra ID, Azure) for an enterprise in Santiago.
- Studying for the SC-300 (Microsoft Identity and Access Administrator) certification.
- Building El Guardián, an automated governance system for small businesses’ Microsoft clouds: identity hygiene, security posture, and cost control, watched daily by software and judged monthly by me. If your company runs on Microsoft 365 and nobody owns its security, that’s the gap I cover (page in Spanish; I work in both languages).
- Writing here: practical notes on identity, PowerShell + Graph automation, AI-assisted IT engineering, and war stories told without polish. I ran everything I publish before writing it down.
Why this site exists
My work, scripts, and lessons used to be scattered, or worse, they lived only in my head. This site is where all of it accumulates: something I own, under my own name, and that should still be useful ten years from now.
