Cybersecurity on a Budget: 10 Steps for Small Businesses

Small businesses are the number one target for cyberattacks. Not because they have the most valuable data, but because they typically have the weakest defenses. 43% of cyberattacks target small businesses, and 60% of those businesses close within six months of a breach.

The good news: you don't need an enterprise security budget to protect yourself. Here are ten steps that cost little or nothing.

1. Enable Multi-Factor Authentication (MFA) Everywhere

This is the single most effective security measure you can implement. MFA blocks 99.9% of automated attacks according to Microsoft.

Where to enable it:

Email accounts (Gmail, Outlook, etc.)
Cloud services (AWS, Azure, Google Cloud)
Banking and financial accounts
Social media accounts
Any application that supports it

Cost: Free with most services.

2. Use a Password Manager

Your team is reusing passwords. I guarantee it. A password manager generates unique, strong passwords for every account and stores them securely.

Recommended options:

Bitwarden (free for individuals, $3/user/month for teams)
1Password ($7.99/user/month for teams)

Cost: $0–8/user/month.

3. Keep Everything Updated

80% of successful breaches exploit known vulnerabilities that already have patches available. Turn on automatic updates for:

Operating systems (Windows, macOS, Linux)
Web browsers
Applications and plugins
Server software
Network equipment firmware

Cost: Free, just requires discipline.

4. Back Up Your Data (and Test the Backups)

Ransomware can't hold your data hostage if you have a clean backup. Follow the 3-2-1 rule:

3 copies of your data
On 2 different types of storage
With 1 copy offsite (cloud storage)

Test your restores quarterly. A backup you've never restored is a hope, not a plan.

Cost: Cloud backup services start at $5-10/month.

5. Train Your Team

95% of cybersecurity breaches involve human error. Regular security awareness training dramatically reduces your risk.

What to cover:

How to recognize phishing emails
Safe browsing habits
Physical security (locking screens, not leaving devices unattended)
What to do if they suspect a breach

Cost: Free resources available from CISA and SANS.

6. Secure Your Email

Email is the #1 attack vector. Beyond MFA:

Enable SPF, DKIM, and DMARC records for your domain (prevents email spoofing)
Use email filtering to catch phishing and malware
Train staff to verify unexpected requests, especially those involving money or credentials

Cost: DNS records are free. Email filtering is usually included in business email plans.

7. Use HTTPS Everywhere

Every page on your website should be served over HTTPS. This encrypts data between your visitors and your server.

Let's Encrypt provides free SSL certificates
Most hosting providers include SSL
Set up automatic certificate renewal

Cost: Free.

8. Limit Access

Not everyone needs access to everything. Practice the principle of least privilege:

Give employees access only to what they need for their job
Remove access immediately when someone leaves the company
Review access permissions quarterly
Use separate admin accounts (don't use admin accounts for daily work)

Cost: Free.

9. Secure Your Wi-Fi

Your office Wi-Fi is a potential entry point:

Use WPA3 encryption (or WPA2 at minimum)
Change the default router password
Create a separate guest network
Hide your network SSID if possible
Update router firmware regularly

Cost: Free (you already have the equipment).

10. Have an Incident Response Plan

When (not if) something happens, you need to know:

Who to contact (IT, legal, insurance, law enforcement)
How to contain the breach
How to communicate with affected parties
How to recover and resume operations

Write it down. Keep it accessible. Review it annually.

Cost: Free to create, invaluable when you need it.

The Bottom Line

Cybersecurity doesn't have to be expensive. These ten steps cost anywhere from nothing to a few dollars per month, and they address the vast majority of threats small businesses face.

The most expensive security measure is the one you implement after a breach.
