Pillar guides
Six in-depth knowledge areas, each anchored by a complete guide and connected to the Barzel product it informs.
The Complete Guide to AI Agent Governance
What agent governance is, why permission at the action level matters, and how approval, risk and audit fit together when software starts acting on its own.
The Complete Guide to MCP Security and Governance
How Model Context Protocol works, where the security risks appear, and what authentication, authorization and audit look like around tool execution.
MCP Governance: Framework, Policy and Operating Model
The four domains you actually govern, three risk tiers policy can key on, five stages of maturity, and who owns which decision.
The Complete Guide to AI Agent Infrastructure
Gateways, control planes, routing and capability management: the infrastructure that decides what AI systems can reach at scale.
FinOps for the AI Era
Why AI workloads break traditional cost management, and how attribution, optimization and cost governance adapt when software spends money autonomously.
AI Agents and the Future of Business Operations
From answers to execution: how agentic workflows differ from traditional automation, and where human-in-the-loop control belongs.

Editorial standard
Answer first, depth second
Each article opens with a direct definition, then covers why the problem exists, how the technology works, who needs it, practical use cases and the limitations. Every substantial article names its author and carries publication and update dates. Where a claim depends on external data, we cite the primary source rather than paraphrasing it.
Guides are written by Mark Alex, founder of Real Biz Digital.
Common questions
About these Insights
What does Real Biz Digital publish here?
Six pillar guides and fifty-nine focused articles — 65 in total — on AI agent governance, MCP governance, MCP security, AI agent infrastructure, FinOps for AI, and intelligent operations. Every article names a human author and a publication date, and claims about protocols link to primary sources.
Where should I start?
If you are new to the subject, start with a pillar guide: AI Agent Governance or MCP Security. If you have a specific decision in front of you, the cluster articles are narrower — What Is an MCP Gateway? and Designing Approval Thresholds are the two most often cited.
Who writes these?
Mark Alex, founder of Real Biz Digital and architect of the Barzel ecosystem. Every article carries his byline and links to his author profile.
Are these articles marketing for the products?
They are written to be useful whether or not you buy anything, and each one links the relevant reference documentation so you can check the specification behind a claim. Where we describe our own products we say so plainly, including what they do not do.
How often is this updated?
Articles carry a published date and a modified date, and both appear in the page’s structured data. Where a figure comes from a marketplace listing or a server’s own enumeration, it is dated at the point of use so you can tell when it was last checked.
