You don’t need a $50,000 security budget to protect your small business. Many of the most effective cybersecurity tools are completely free — and most take less than an hour to set up.
Here are 10 free tools every small business should be using right now.
1. Have I Been Pwned (haveibeenpwned.com)
This free service lets you check whether your email address or any of your employees’ email addresses have been exposed in a known data breach. If your credentials are in a breach database, attackers may already have your passwords.
Use it for: Monthly employee email audits, new hire onboarding checks.
2. Bitwarden (bitwarden.com)
A free, open-source password manager that lets your team store, generate, and share passwords securely. The free plan covers individuals; the Team plan ($3/user/month) adds sharing features.
Why it matters: Weak, reused passwords are the #1 cause of business breaches.
3. Google Workspace’s 2-Step Verification
If your business uses Gmail or Google Workspace, enabling 2-step verification (2FA) is free and takes 5 minutes. This single step blocks 99.9% of automated attacks on your Google accounts.
How to enable: myaccount.google.com → Security → 2-Step Verification.
4. Malwarebytes Free (malwarebytes.com)
The free version of Malwarebytes provides excellent on-demand malware scanning for Windows and Mac. It detects threats that traditional antivirus software often misses.

6. Google Search Console (search.google.com/search-console)
