PS HarriJaakkonen :~> Get-AboutMe

I design and implement Zero Trust architectures using Microsoft Entra ID, Defender suite, and Sentinel. I specialize in Conditional Access, PIM, workload identities, and automated security guardrails via Microsoft Graph API.

My work spans SAML/OIDC/OAuth2 integrations, B2B/cross-tenant scenarios; AI security with Security Copilot, Agentic AI, and AI-based tool design; and cloud defense across Azure and multi-cloud environments.

I support presales and delivery, mentor engineers, and drive least-privilege IAM. I'm not here to maintain systems — I'm here to evolve them.

Sharing knowledge builds stronger defenders. I publish tools and learning content to help teams and individuals secure cloud estates.
