5 Steps to Strengthen Your SMB Cyber-Defense

Most small and midsize businesses do not get breached because they lacked an expensive tool. They get breached because something basic was left open: a reused password, an unpatched laptop, an email that looked routine. The good news is that the basics are within reach of any organization, and they do most of the work.

Here are five steps worth taking in order.

1. Turn on multi-factor authentication everywhere it is offered

Stolen and guessed passwords remain one of the most common ways attackers get in. Multi-factor authentication means a password alone is not enough. Start with email and Microsoft 365, then banking, payroll, and any system that holds client or patient information. Prefer an authenticator app or security key over text messages where you can.

2. Know what you have

You cannot protect a device or account you do not know exists. Keep a simple inventory of laptops, phones, servers, cloud services, and who has access to each. Remove accounts for people who have left. This is unglamorous work, and it closes more gaps than most security products.

3. Keep systems patched

Software updates fix known weaknesses, and attackers look for organizations that have not applied them. Set operating systems and browsers to update automatically, and assign someone to check that updates are actually landing. Replace hardware and software that the vendor no longer supports.

4. Treat email as the front door

Phishing and business email compromise target people, not machines. Add email filtering, label messages from outside the organization, and agree on one firm rule: any request to change payment details or send money is confirmed by phone, using a number you already have. Short, regular awareness training helps staff recognize what to question.

5. Decide now what you will do when something goes wrong

An incident is a bad time to work out who is in charge. Write down who makes decisions, who you call, how you will communicate if email is down, and where your backups are. One page is enough to start. Then walk through it once a year.

Where to begin

If you do only one thing this month, make it step one. If you are unsure where your gaps are, a short assessment will tell you which of these five would reduce the most risk for your business first.
