5 Steps to Protect Your Company's Network Right Now

Most small business owners assume hackers only go after big companies. The truth? Small businesses are targeted more often, precisely because attackers know most of them haven't set up basic protections. The good news is that a handful of simple steps can eliminate the majority of your risk.

Here are five things you can do right now to lock down your company's network and protect your data. None of them require a technical background.

Step 1: Change Your Router's Default Password

Your router is the front door to your entire network. When it ships from the factory, it comes with a default username and password, usually something like admin / admin or admin / password. These defaults are publicly listed online. Any attacker who gets near your network can look them up in 10 seconds.

What to do: Log into your router's settings page (usually by typing 192.168.1.1 or 192.168.0.1 into your browser), find the admin password section, and change it to something long and unique, at least 12 characters, mixing letters, numbers, and symbols.

Why it matters: An attacker who gets into your router can redirect all your internet traffic, intercept passwords, and spy on everything your business does online.

Step 2: Separate Your Guest Wi-Fi from Your Business Network

Most modern routers let you create a separate "guest network." This is one of the most valuable, and most overlooked, security features available to small businesses.

What to do: Enable the guest network feature on your router. Put visitors, customers, and personal devices on the guest network. Keep your business computers, printers, and servers on the main network. Never share the main network password with anyone who doesn't absolutely need it.

Why it matters: If a guest's device is infected with malware, a separate guest network stops that infection from spreading to your business systems. It also means a compromised personal phone can't reach your company's financial data or client files.

Step 3: Turn On Automatic Updates, Everywhere

The most common way attackers get into business networks is through software that hasn't been updated. Every update patches security holes that have been discovered since the last version. When you skip updates, you're leaving those holes wide open.

What to do: Enable automatic updates on every computer, phone, and tablet in your business. Check your router's settings for a firmware update option, many routers can also update automatically. Don't ignore the "update available" notifications on your software.

Why it matters: In 2023, over 60% of small business breaches exploited a vulnerability that already had a patch available. The fix existed, the business just hadn't applied it.

Step 4: Enable Multi-Factor Authentication (MFA) on Everything

Multi-factor authentication, also called MFA or two-step verification, means that even if someone steals your password, they still can't get into your account without a second piece of proof (usually a code sent to your phone).

What to do: Turn on MFA for your email, banking, accounting software, cloud storage (Google Drive, Dropbox, etc.), and any other account that holds sensitive business data. Most services offer it for free under Settings → Security.

Why it matters: Passwords get stolen all the time, through phishing, data breaches at other companies, or simple guessing. MFA means a stolen password alone is useless. Microsoft reports that MFA blocks over 99.9% of automated account attacks.

Step 5: Back Up Your Data, and Test the Backup

Ransomware attacks lock you out of your own files and demand payment to get them back. The only real protection against ransomware is having a clean backup that attackers can't reach.

What to do: Follow the 3-2-1 rule: keep 3 copies of your data, on 2 different types of storage, with 1 copy offsite (like a cloud backup service). Make sure backups run automatically. Most importantly, test your backup by actually restoring a file from it. A backup you've never tested is a backup you can't trust.

Why it matters: The average ransomware payment for a small business is now over $100,000. A proper backup means you can restore your files and get back to work without paying anything.

These five steps won't make your business completely unhackable, nothing can. But they will eliminate the most common attack paths and put you well ahead of the majority of small businesses. Most breaches happen because basic protections weren't in place. Don't let that be your story.
