    Key takeaways

    • Problem: the business impact comes primarily from operational downtime and slow recovery.
    • Solution: a 30-day plan focused on identity + tested backups + detection + procedures.
    • Result: drastically reduce the risk of prolonged downtime with simple, verifiable controls.

    CEO objective: make the company resilient. In 2026, the difference comes down to the time it takes to detect, isolate, and restart.

    The essentials in 30 seconds

    Minimal checklist

    • [ ] MFA everywhere (email, admin, VPN)
    • [ ] Backups with 1 immutable/offline copy + restore test
    • [ ] EDR on workstations/servers + ability to isolate a machine quickly
    • [ ] Anti-fraud process (bank detail changes) + targeted awareness training

    30-day plan (week by week)

    Week 1 — Identity

    • MFA on email + admin accounts
    • Separate + named admin accounts
    • Quick access review (former employees)

    Week 2 — Backups and recovery

    • 1 immutable/offline copy
    • Restore test (documented proof)
    • Recovery priorities (ERP/file shares/email)

    Week 3 — Detection / containment

    • EDR on workstations/servers
    • Procedure: isolate a machine in 2 minutes
    • Centralize minimum logs (email, admin)

    Week 4 — Patching + vendors + anti-fraud

    • Patch internet-facing components (VPN/gateways/OS)
    • Limit and audit vendor access + reversibility
    • Bank detail change process (dual approval on a different channel)

    Day zero: what to do in 60 minutes

    1. Isolate: disconnect suspicious machines from the network.
    2. Preserve: don't 'clean up' everything (evidence matters).
    3. Decide: prioritize continuity (restore) vs. investigation.
    4. Communicate: internally first, then externally if needed.

    FAQ — SMB cybersecurity

    What is the best security investment for an SMB?

    Identity (MFA) + tested backups. This duo prevents the vast majority of worst-case scenarios.

    How do you reduce wire fraud (BEC)?

    Simple rule: every bank detail change must be verified on a different channel. And prioritize awareness training for finance teams and executives.
