Small Business Cybersecurity Guides (Canada)
Practical, deployment-focused guides for Canadian small businesses running Microsoft 365 — covering phishing prevention, MFA rollout, Conditional Access policies, ransomware protection, and backup strategy. Written by the managed IT team at CtrlShift IT Services.
What cybersecurity controls should small businesses set up first?
Start with identity protection — enable MFA on every account before anything else. From there, the recommended sequence is: MFA rollout across all staff, Conditional Access baseline policies to enforce context-aware sign-in rules, phishing protection in Microsoft 365 Defender, then verified backup coverage for Exchange, SharePoint, OneDrive, and Teams. Staff awareness training runs in parallel throughout. Each layer compounds the one before it, so sequence matters.
