The second benefit of implementing captive WiFi is keeping your WiFi usage legal and ethical.

When customers agree to the terms and conditions, you are no longer responsible for what they do on the Internet. This way, you’ll avoid any lawsuit that comes your way if authorities notice illegal or unethical activities on your network.

However, you must include a statement absolving your business of your customers’ activities. The firewall rules we mentioned above also help you block such websites on your network or restrict access to them.

This way, you can show the authorities you took steps and that the customers took responsibility for themselves.

3. Promote Your Business

Almost all WiFi marketing solutions allow you to customize the captive portal. This presents you with the perfect opportunity to promote your business.

In fact, WiFi marketing strategies like displaying banners on the captive portal are effective.

Most of your customers will visit that page, so they’ll look at those banners at least once. All you have to do is make them enticing enough. For example, you can display important updates, in-store discounts, loyalty program updates, etc.

Not only will this make your offers more effective, it will also improve brand awareness.
