Wi-Fi Security Best Practices & How to Secure Your Network
Did you know that unsecured Wi-Fi networks cause 72% of business data breaches¹? This shocking statistic shows just how vulnerable your business can be if your network isn't properly secured. A weak Wi-Fi network is a gateway for hackers. It puts sensitive data, client information, and internal communications at risk.
Securing your Wi-Fi network should be a top priority for any business. In this guide, we'll walk you through essential Wi-Fi security best practices to protect your network from potential cyber threats. You'll discover how simple tweaks can protect your data and secure your network. We'll touch on turning on encryption, making strong passwords, and setting up guest networks.

Essential Wi-Fi Security Best Practices for Your Business Network
Securing your Wi-Fi does more than stop threats. It also helps your whole network run smoothly and safely. Here are some of the most critical steps to protect your business Wi-Fi.
1. Use WPA3 Encryption for Your Wi-Fi
WPA3 is the most secure Wi-Fi encryption standard available today. Unlike older protocols such as WPA2 or WEP (Wired Equivalent Privacy), WPA3 offers stronger encryption. This makes it much harder for hackers to intercept data or guess your password. If you're still using WPA2, it's time to upgrade your router to one that supports WPA3. This upgrade keeps your business data secure and optimises your overall network stability. The National Cyber Security Centre (NCSC) says that:
Encrypting the private data of an individual (and minimising the number of parties that have access to decrypt the private data) can be proportionate measures for minimising the exposure of the private data, helping to ensure that it is only used for the stated purpose.
WPA3 encryption should, therefore, be a priority for all companies, especially those that want to maintain data integrity and protect their sensitive information.
2. Create a Strong, Unique Password
It might seem obvious, but using a strong, unique password for your Wi-Fi network is often overlooked. Default or easily guessable passwords are an open invitation for hackers to gain access. Create a password that's at least 20 characters long and includes a combination of upper and lower case letters, numbers, and symbols.
Avoid using business-related terms or personal information. A unique password is harder for hackers to crack, significantly reducing the risk of unauthorised access. For more Tips for Staying Secure While Working from Home, check out our blog.
3. Set Up a Separate Guest Network
Letting visitors use your business Wi-Fi may seem helpful, but it can expose your network to risks. A separate guest network keeps your main business network isolated from outside devices. By doing this, you ensure that visitors can access the internet without compromising your sensitive data and systems.
Most modern routers allow you to easily set up a guest network, making this an easy but critical step in protecting your business. This practice works well if your business gets a lot of visitors or has remote workers on the network.
4. Regularly Update Router Firmware
Outdated router firmware is one of the easiest ways to leave your Wi-Fi network vulnerable to attack. Manufacturers often release security patches and bug fixes to address vulnerabilities. If you ignore these updates, your network could be at risk from cybercriminals who seek to exploit known weaknesses.
Set your router to automatically install updates or manually check for firmware updates at least once every few months. Keeping your router's firmware up to date is one of the simplest yet most effective ways to secure your network.
5. Use a VPN for Encrypted Communications
Using a Virtual Private Network (VPN) is a smart move if you have remote workers or handle sensitive data. A VPN encrypts your data, making it harder for hackers to steal your information. This is especially important when you use unsecured Wi-Fi networks, like public hotspots.
A business-grade VPN ensures that communications stay private and secure. This is crucial for employees working remotely or accessing the network outside the office.
6. Implement Firewalls to Protect Your Network
A firewall acts as a defensive barrier, blocking potentially harmful traffic while allowing safe data to pass through. Most routers include built-in firewall features. Still, consider looking into dedicated firewall hardware or software for more protection.
Firewalls help block unauthorised traffic and prevent cyberattacks from infiltrating your network. Always ensure that your router's firewall is activated and configured to block any suspicious traffic.
Common Wi-Fi Security Mistakes to Avoid
Don't expose yourself to cyberattacks. Here are the most common errors and how to avoid them:
- Using Default Passwords & Network Names: Always change the default network name (SSID) and router password to something unique and complex. Default settings are widely known and easy to exploit.
- Forgetting to Enable Encryption: Ensure that encryption is enabled on your router, either WPA2 or WPA3. Without encryption, your network is an open target for hackers.
- Neglecting Software and Firmware Updates: Never skip router updates. Firmware updates address security flaws and boost router performance, protecting your business from emerging threats.
How to Check if Your Wi-Fi Network Is Secure
Is your Wi-Fi network secure? Here's how you can check:
- Check Your Wi-Fi Router's Settings: Log in to your router's admin page and verify that encryption is enabled and the password is strong. You should also ensure that you're using WPA3 or WPA2 encryption.
- Monitor Network Traffic for Suspicious Activity: Keep an eye on network traffic using simple tools to detect unauthorised devices or unusual activity. These tools can also alert you to potential breaches.
- Use Online Wi-Fi Security Check Tools: Several free online tools allow you to scan your network for vulnerabilities. These tools can test for weak encryption, open ports, and more.
