5 Cybersecurity Mistakes That Are Costing Your NJ Business

Small businesses get targeted because the basics are often weak. We see the same handful of preventable security gaps across South Jersey over and over again.

The good news is that most of them are fixable. Here are five of the biggest mistakes we see and what to do about them.

Mistake #1: Skipping Software Updates

What we see:

• Computers running Windows 10 from 2019 without a single update installed
• Browsers so outdated they can't load modern websites securely
• Routers that haven't been updated in years, leaving your entire network exposed

How to fix it:

Enable automatic updates everywhere—Windows, Office, browsers, antivirus, and any business software you use. Set them to install outside business hours so they don't slow you down. For critical infrastructure like servers and firewalls, schedule updates monthly. This isn't optional IT. It's the first line of defense.

A managed IT service like ours handles this automatically, testing and rolling out updates across all devices on your schedule. You never have to think about it.

Mistake #2: Weak Passwords and No Multi-Factor Authentication

What we see:

• Shared passwords written down in notebooks or spreadsheets
• Employees using the same password for email, OneDrive, and personal accounts
• No MFA enabled on critical accounts like email or Microsoft 365 admin access
• Default passwords on routers, printers, and network devices

How to fix it:

First, implement a password manager so employees can generate and store strong, unique passwords. Use Microsoft 365's built-in passwordless sign-in (Windows Hello or Microsoft Authenticator) or at minimum, require MFA on all accounts that matter: email, cloud storage, financial systems, and admin access. MFA doesn't require expensive hardware—authenticator apps on phones work perfectly.

We also recommend a password policy: at least 12 characters, no reuse of old passwords, and automatic resets every 90 days. Yes, it's annoying. No, it's not negotiable if you want to stay secure.

Mistake #3: No Backups or Outdated Backup Strategies

What we see:

• No offsite backups—only local copies or USB drives
• Backup drives that haven't been tested in years
• Backups stored on the same network, vulnerable to the same attack
• Microsoft 365 data assumed to be safe because "it's in the cloud" (it isn't)

How to fix it:

Follow the 3-2-1 backup rule: Keep three copies of critical data, on two different types of storage, with at least one copy offsite. For example: one live copy on your server, one backup on an external drive kept onsite, and one backup in cloud storage that's disconnected from your network. Test your backups monthly by actually restoring a file. If you can't restore it, it's not a backup—it's just something taking up space.

For Microsoft 365 data, use a backup solution like Veeam or Commvault. Microsoft backs up your data, but not for ransomware recovery. You need to own a separate, immutable copy.

Mistake #4: Not Training Your Team on Security

What we see:

• Employees clicking links in emails that say "Verify Your Account" or "Urgent: Update Payment Info"
• Passwords shared over email or chat
• Confidential documents sent to personal email addresses
• No reporting mechanism when someone spots a suspicious email

How to fix it:

Implement a security awareness program. Quarterly training on recognizing phishing, handling sensitive data, and reporting suspicious activity is the bare minimum. Many companies we work with use tools like KnowBe4 that send fake phishing emails and track who clicks. The ones who fail get coaching, not punishment. It's about building a security culture, not blaming people.

Also, create a simple reporting system: a dedicated email or channel where employees can flag suspicious emails or activity without fear. You want people to report problems, not hide them.

Mistake #5: Trying to Go It Alone Without Professional Help

What we see:

• Businesses with no documented security policy
• IT decisions made in a vacuum without a long-term security plan
• Shared admin accounts with no accountability
• No outside review of backups, patching, or access controls

How to fix it:

Bring in an IT partner who can review your environment regularly, close obvious gaps, and turn security into a repeatable process instead of a once-a-year scramble.

Final Takeaway

Most small-business security problems are not exotic. They come from skipped basics: updates, passwords, backups, training, and lack of oversight. Fix those five areas and you dramatically reduce your risk.
