You don't need an enterprise budget to be genuinely secure. These are the foundational controls every small and mid-sized business on Microsoft cloud should have in place.
Attackers don't skip small businesses — they target them precisely because defences are often thinner. The good news: the Microsoft cloud gives SMEs access to the same security controls the enterprises use. You just have to turn them on and configure them well.
Identity is your real perimeter
The firewall mattered when everyone worked in one building. Today, identity is the perimeter. The single highest-value control you can deploy is phishing-resistant multi-factor authentication for every account, enforced through Entra ID conditional access.
- Require MFA for all users — no exceptions for admins.
- Block legacy authentication protocols that bypass MFA.
- Use conditional access to restrict risky sign-ins by location and device state.
- Run regular access reviews and apply least privilege.
Manage and protect every endpoint
A compromised laptop is a doorway into everything. With Microsoft Intune you can enforce disk encryption, automatic patching and compliance policies across every device — and remotely wipe anything lost or stolen.
Assume breach: back up and plan recovery
Ransomware resilience comes down to one question: can you restore? Immutable, off-site backups with a tested recovery runbook turn a potential business-ending event into an inconvenience.
Watch your Microsoft Secure Score
Secure Score gives you a prioritised, measurable view of your posture in Microsoft 365. It's the simplest way for a non-specialist to see what to fix next and to track improvement over time.
Security for an SME isn't about buying more tools. It's about correctly configuring the powerful ones you already pay for.
A focused hardening engagement usually moves the needle dramatically in a couple of weeks. If you've never had a security review, that's the place to start.
