About Praesidium
Matt Day · Founder & Principal Security Advisor

Security thinking shaped in the real world, built for modern cloud and AI systems.

Praesidium Security Advisors is led by a Texas-based security professional with more than 15 years across physical and cyber security. Before moving deeper into cloud security, he served as a police officer in Florida, where the foundational principles of security were learned firsthand: know the environment, understand the threat, protect what matters, and act with clarity under pressure.

Today, that same practical mindset guides Praesidium's work in cloud and AI security. The focus is simple: help organizations see what they have, understand where risk is hiding, and design security foundations that can scale with the business.

You cannot protect what you do not know you have.

Operating Philosophy

Security starts with visibility, then becomes architecture.

The strongest programs are not built from tools alone. They are built from clear ownership, known assets, intentional access, practical evidence, and leadership that can make calm decisions when the stakes rise.

01

Know what exists

Unknown assets, forgotten accounts, and invisible data paths are where risk quietly gathers.

02

Design before tooling

Security tools work best when identity, logging, boundaries, and ownership are already intentional.

03

Make decisions usable

Good security advice should be clear enough for executives and practical enough for engineers.
