A step-by-step guide to protect your business from common cyber threats
Use a password manager to generate and store long, random passwords for every account. Never reuse passwords.
Turn on MFA everywhere you can — email, bank portals, cloud services — to block attackers even if a password is stolen.
Enable automatic updates for your OS, browsers, and key applications. Patches close security holes fast.
Follow the 3-2-1 rule:
Install a reputable security suite on every workstation and server. Schedule daily scans and real-time protection.
Enable hardware or software firewalls to block unauthorized access. Segment guest Wi-Fi from your corporate network.
Run quarterly phishing drills. Teach staff to spot suspicious emails, links, and attachments before they click.
Require VPN or zero-trust tools for offsite logins. Disable remote desktop unless absolutely necessary.
Give each user the minimum access they need. Remove admin rights from daily-use accounts.
Encrypt sensitive files at rest (disk encryption) and in transit (HTTPS, SFTP) to keep data unreadable if intercepted.
Document who to call, how to isolate systems, and where your offline backups live. Test the plan at least once a year.
Require proof of security practices from any third party handling your data. Include cybersecurity clauses in contracts.
Run monthly scans of your network and public-facing systems. Patch or remove any outdated services.
Centralize system and access logs. Set up alerts for unusual login locations, repeated failures, or large file transfers.
Write simple security policies (password rules, device usage, data classification). Review and update them every 6 months.
Tip: Tick off each item as you complete it, and revisit the checklist quarterly to stay ahead of evolving threats.
