About Fastnet

Fastnet is an award-winning internet service provider from the heart of Brighton, dedicated solely to businesses.

We have been helping private and public sector organisations get connected, stay safe and grow online for more than 20 years. From the dawn of dial-up to today’s superfast fibre-optic connectivity we have evolved and invested to give our customers the fastest and most reliable internet services available, all backed by our outstanding customer service. You can read more about our story here.

From digital start-ups to multinational corporations, we support businesses of all shapes and sizes.

And, as one of the few ISPs to be fully owner-managed, we also know what it takes to run a business from the ground up — and the importance of seamless connectivity and data protection.

We believe we succeed when our customers don’t have to think about their internet services — they just work. And if they do need to speak to us, it should be like talking to a colleague.

We’re proud that many of our clients have been with us for over 10 years. Because as well as providing quality internet services, we simply believe in being a good company.
