Moving to Cloud? Security Should Move First.

Cloud misconfigurations are a top breach cause globally — not sophisticated attacks, just settings left wrong. Here is why security should be sequenced before workloads in any cloud migration.

Cloud adoption is accelerating across Kenya and Australia. Businesses that were running on-premise servers five years ago are now moving to Microsoft 365, Azure, AWS and SaaS tools at pace. That's the right direction. But there's a pattern that shows up consistently in security reviews: workloads moved, identity security didn't.

Cloud misconfigurations are now one of the top three breach causes globally. Not sophisticated attacks — misconfigurations. Settings left at defaults. Access controls not reviewed. Logging not enabled. These are preventable, and they're preventable at the point of migration.

What 'security should move first' actually means

It doesn't mean delaying your migration. It means sequencing it correctly. Before the first workload moves, four things should be in place:

1. Identity — MFA and Conditional Access

Identity is the new perimeter. In a cloud environment, there's no physical network boundary protecting your data. What replaces it is strong identity security. Before migrating, every user account should have MFA enforced — not optional, not encouraged, enforced. And Conditional Access policies should define when and from where logins are permitted.

A cloud environment without Conditional Access allows login from any device, any location, any risk level. That's not a cloud environment — that's an open door with a weak lock.

2. Device trust

Which devices are allowed to access your cloud environment? Personal devices, unmanaged contractor laptops, and machines running end-of-life operating systems present significantly different risk profiles from managed, Intune-enrolled corporate devices. Establishing device compliance policies before migration means you control what connects from day one — not after an incident reveals the gap.

3. Data protection policies

What can users do with your data once they can access it? Can they share files externally? Can they forward emails to personal accounts? Can they download entire SharePoint libraries to unmanaged devices? Default settings on most cloud platforms are permissive. Defining data protection policies at migration prevents data loss events that would otherwise be invisible.

4. Logging and monitoring

You cannot investigate an incident in an environment with no logs. Unified audit logging should be enabled from day one. Sign-in activity, file access, admin actions, external sharing events — all of it captured and retained for a meaningful period. This isn't just for incident response. It's for compliance, operational awareness, and knowing what normal looks like before something abnormal happens.

Cloud done right is more secure than most on-premise setups a small business could maintain on their own. The key word is 'done right.' Security first, workloads second.

A practical pre-migration checklist

MFA enforced for all user accounts via Conditional Access
Legacy authentication protocols (SMTP auth, IMAP, POP3) disabled
Admin accounts separated from standard user accounts
Device compliance policies defined and Intune deployment planned
SharePoint and OneDrive external sharing settings reviewed and restricted
Audit logging enabled — all services, retained for 90+ days
Email authentication configured — SPF, DKIM, DMARC published
Backup strategy defined for cloud data (not relying on native platform retention)
