What goes wrong repeatedly.
NO EMERGENCY ACCESS ACCOUNT
A policy then locks out every administrator.
MULTI-FACTOR AUTHENTICATION NOT ENFORCED
The commonest route to compromise, and entirely preventable.
LEGACY AUTHENTICATION LEFT ENABLED
Which bypasses the protection you configured.
LICENCES ASSIGNED TO PEOPLE WHO LEFT
Billed monthly, indefinitely.
TREATING SYNCHRONISED STORAGE AS BACKUP
Until a deletion or encryption propagates.
UNCONTROLLED CREATION OF TEAMS AND SITES
Producing sprawl nobody can navigate.
BREAKING PERMISSION INHERITANCE EVERYWHERE
So nobody can establish who can see what.
BUILDING IN THE DEFAULT POWER PLATFORM ENVIRONMENT
With no governance and no path to production.
IGNORING DELEGATION WARNINGS
Producing applications that silently return wrong results at scale.
DOMAIN MEMBERS POINTED AT PUBLIC DNS
Breaking authentication in ways that appear unrelated.
RESOURCES LEFT RUNNING IN AZURE
The largest single source of avoidable cost.
SECRETS IN CONFIGURATION AND SCRIPTS
Which end up in version control history permanently.
WHAT PREVENTS MOST OF THESE
Governance decided early, applied consistently, and reviewed.
