A Cybersecurity Checklist for Thai SMBs

Attackers increasingly target small and mid-sized businesses precisely because they assume defences are weak. The good news: most breaches exploit a handful of well-understood gaps, and closing them does not require an enterprise budget. Here is a practical baseline for Thai SMBs.

Turn on multi-factor authentication everywhere

Stolen passwords cause a large share of breaches. Multi-factor authentication (MFA) on email, remote access, and admin accounts is the single highest-impact control you can deploy this week, and it is usually free.

Patch and back up — and test the backups

Unpatched software is how ransomware gets in. Keep operating systems and applications updated, and maintain backups that are isolated from your network. A backup you have never restored is a hope, not a plan — test it.

Train your people

Most attacks start with a convincing email. Short, regular phishing-awareness training measurably reduces click rates and is far cheaper than incident recovery.

Know who to call

Decide in advance who responds to an incident and how. A simple, written response plan — even one page — turns a panicked scramble into a controlled process, and it is also expected under the PDPA.
