5 Network Security Checks Every Beaverton Small Business Should Do

Network security doesn't require a team of experts or expensive software. Many threats to small businesses come from basic oversights—things you can check yourself right now.

At Wolex Technologies, we work with small businesses throughout Beaverton, Hillsboro, and the Portland Metro area. We've noticed that most security breaches and network issues happen because simple checks were skipped. Here are five practical security checks you should review today.

Check 1: Review Your Firewall Rules and Remote Access

Your firewall is your first line of defense. If it's not configured properly, you might be exposing your business to the internet unintentionally.

Ask yourself:

• • Do you have remote access enabled? If yes, is it restricted to authorized users only?
• • Are there old firewall rules you no longer need? Outdated rules create security gaps.
• • Does your firewall have the latest firmware updates?
• • Can you identify which ports and services are open to the internet?

If you can't answer these questions, your firewall probably needs attention. This is where a network security checkup becomes valuable—we can review your firewall configuration and fix any exposure.

Check 2: Separate Guest Wi-Fi from Business Devices

Guest Wi-Fi is convenient for visitors, but if it's on the same network as your business devices, you're creating unnecessary risk.

If a guest's device gets infected or compromised, it could potentially access your business files, printers, and systems. Separation is simple:

• • Create a separate guest network on your Wi-Fi router
• • Use a strong password (not your business password)
• • Change it regularly
• • Disable file sharing between networks

Most small business routers have a "guest network" feature. If yours doesn't, or if you're unsure how to set it up, that's a sign you might need professional Wi-Fi setup.

Check 3: Review VPN and Remote-Work Access

If your team works from home or uses VPN, make sure access is locked down properly.

Review:

• • Who has VPN access? Do former employees still have it?
• • Are VPN passwords strong and unique (not shared)?
• • Are you using multi-factor authentication (2FA) for VPN login?
• • Is your VPN encrypted and using current security standards?

Remote access is essential for modern work, but it's also a common entry point for hackers. If you're not sure whether your VPN is secure, get it reviewed by a professional.

Check 4: Check Network Devices, Updates, and Default Passwords

Outdated software and default passwords are easy targets for attackers.

Go through your network:

• • Document all network devices (firewall, router, switches, access points, printers)
• • Check if firmware updates are available for each device
• • Change default passwords on network equipment (many still ship with factory defaults)
• • Check computers and servers for pending software updates

This takes time but is one of the highest-impact security tasks. Many breaches happen because devices weren't patched. Set a reminder to check for updates monthly.

Check 5: Document Your Network and Backup Critical Systems

You can't protect what you don't understand. Create a simple network diagram showing:

• • What devices are on your network?
• • What data is critical to your business?
• • Where is that data stored?
• • How often are backups being made?
• • Where are backups stored (cloud, external drive, offsite)?

Ransomware attacks are on the rise. Even with good security, backups are your recovery plan. Make sure you have recent backups of critical files, and test that they actually restore.

Documentation also helps if you ever need to upgrade your network infrastructure or work with an IT consultant. It saves time and ensures nothing gets missed.

When to Get Professional Help

These five checks are practical starting points. If you're unsure about any of them, or if you discover issues, it's time to get professional help. Here are signs you should reach out:

• • You can't answer these questions for your own network
• • Your firewall rules are a mess or haven't been reviewed in years
• • You don't know who has access to what (former employees, contractors, etc.)
• • You've had a security incident or close call
• • You're planning to hire remote staff or open a new office

A professional network security checkup takes a few hours and covers firewall, Wi-Fi, VPN, backups, and access controls. It's affordable and often catches issues you wouldn't find on your own.
