If cybersecurity feels overwhelming, start with five “quick wins” that cut the majority of SME risk fast. Each one is measurable, affordable, and feasible without a big IT team.

1) Turn on MFA (Multi-Factor Authentication) everywhere

Most breaches begin with stolen passwords. Adding MFA to email, finance apps, VPN, and admin panels shuts down the simplest attacks. Pair with a password manager + enforced complexity and rotation for shared/admin accounts. MFA is a Cyber Essentials fundamental and a top recommendation across UK guidance. NCSC

How to do it this week:

• Enforce MFA for Microsoft 365/Google Workspace and any remote access.
• Disable legacy authentication.
• Require app-based authenticators (or FIDO keys for admins).

2) Patch high-risk systems on a schedule

Set a cadence (e.g., weekly for critical patches; monthly for standard). Many high-profile breaches come from known vulnerabilities months after patches were available. NCSC’s guidance on vulnerability management is clear: scanning + remediation cycles are essential. NCSC

How to do it this week:

• Run a vulnerability scan (internal + external).
• Patch anything marked Critical/High first; document exceptions. NCSC

3) Secure email properly (SPF, DKIM, DMARC) + anti-phishing

Spoofed email is still a top attack vector. Implement DMARC, SPF, and DKIM to reduce impersonation, and tune your email security to flag suspicious attachments/links. Phishing remains the workhorse for ransomware crews. Verizon

How to do it this week:

• Add SPF/DKIM records; set DMARC to quarantine/ reject after monitoring.
• Roll out user phishing awareness with realistic simulations.

4) Back up like your business depends on it (it does)

Ransomware losses are so large because recovery is hard. Backups must be regular, tested, off-network (immutable or offline), and cover critical systems + cloud data. Industry data shows the financial toll of ransomware is still severe; resilience starts with restore. Axios

How to do it this week:

• Daily backups for critical systems; weekly restore tests.
• Keep at least one backup copy offsite/immutable.

5) Least privilege + admin hygiene

Compromised admin accounts equal instant disaster. Limit who has admin rights, segment networks, and monitor for unusual access. Tie this to a short incident response checklist so your team knows who calls whom and what gets isolated first. UK government surveys show SMEs are improving on incident planning—keep that momentum. GOV.UK

How to do it this week:

• Remove standing admin where possible; use just-in-time elevation.
• Create a 1-page incident plan (contacts, isolate steps, legal/comms).

Bonus: Aim for Cyber Essentials

Beyond quick wins, Cyber Essentials gives you a UK-recognised baseline: MFA, patching, secure configuration, malware protection, and access control. It’s achievable for SMEs and increasingly requested in supply chains. NCSC

Takeaway: Do these five, then confirm with a vulnerability scan. You’ll remove the cheapest attack paths—and sleep a lot better. NCSC
