🔐 Top 7 Cybersecurity Mistakes Small Businesses Make — and How to Fix Them

Many cyberattacks happen not because of advanced hackers — but because of simple mistakes. These are the top 7 cybersecurity errors small businesses make every day, and exactly how to prevent them.


1. Using Weak or Reused Passwords

Many employees still use simple passwords like 123456, or reuse the same password across multiple accounts. This makes it easy for attackers to break into your systems using leaked credentials from other platforms.

Fix It:

  • Use strong, unique passwords for each account.
  • Store them in a password manager like Bitwarden or 1Password.
  • Turn on Multi-Factor Authentication (MFA) wherever possible.

2. Clicking on Suspicious Emails (Phishing)

Phishing emails trick you into clicking malicious links or downloading fake attachments. These emails often pretend to be from banks, clients, or even your boss.

Fix It:

  • Always check the sender’s email address carefully.
  • Hover over links before clicking.
  • Report anything suspicious to your IT person or supervisor.

3. Giving Too Much Access to Too Many People

Many small businesses give all staff full access to everything — emails, customer records, admin settings. This increases the damage if someone makes a mistake or gets hacked.

Fix It:

  • Follow the “least privilege” rule: staff only get access to what they need.
  • Use roles or permissions inside apps like Google Workspace, Dropbox, etc.
  • Review user access regularly and remove old accounts.

4. Not Installing Updates (Software, Devices, Phones)

Hackers exploit old vulnerabilities in software. Every time you delay an update, you leave the door open.

Fix It:

  • Turn on automatic updates on computers, phones, and apps.
  • Restart devices regularly to complete updates.
  • Don’t ignore update notifications — they exist for a reason.

5. Using Public Wi-Fi Without Protection

Working from a café, airport, or train station? Public Wi-Fi networks can be monitored by attackers looking to steal login details or company data.

Fix It:

  • Use a VPN (Virtual Private Network) when working on public Wi-Fi.
  • Never access sensitive documents or logins on untrusted networks without protection.
  • If possible, use your mobile hotspot instead.

6. No Backup Strategy

A ransomware attack, device crash, or accidental deletion can wipe out years of data. Many small businesses don’t have any proper backup system.

Fix It:

  • Back up important data to the cloud and/or an external drive.
  • Use automated daily backups where possible.
  • Test your backups — don’t wait for disaster to find out they don’t work.

7. Thinking “It Won’t Happen to Us”

The most dangerous mistake? Believing you’re too small to be targeted. In reality, small businesses are targeted more often, because they’re seen as easy victims.

Fix It:

  • Take basic cybersecurity seriously, even if you’re a small team.
  • Train your staff — even one mistake can cost you.
  • Stay updated with tips from your BitsSecured membership — you’re already on the right path.

Final Thought

Cybersecurity is not about perfection — it’s about reducing your risks. Most attacks succeed because of small, avoidable mistakes. Fix these 7 issues and your company becomes a much harder target immediately.
