A practical guide covering identity controls, email protection, user lifecycle and collaboration governance.

Start with business risk

Identify the work the organization cannot afford to interrupt. Map the people, systems, information and suppliers that support those operations. Assign an owner to each important control and document what happens when a device, account, application or vendor fails.

Core controls

Identity

Require multi-factor authentication, protect administrator accounts, review access and remove accounts promptly when roles change.

Systems

Maintain supported devices, apply updates, protect endpoints and configure email authentication to reduce impersonation.

Recovery

Back up critical information, protect backup credentials and test recovery against documented business requirements.

Make security repeatable

Use documented onboarding and offboarding, recurring reviews, clear escalation paths and scheduled recovery exercises. Reporting should explain unresolved risk in plain language, identify the owner and record the next action.

Questions for an IT provider

Which users, devices and systems are included?
Who monitors alerts and handles escalation?
How are backups verified and recovery tested?
Which security responsibilities remain with the client?
What documentation is maintained?
How does transition and offboarding work?
