What makes .DEV a secure namespace?

The .DEV Top Level Domain (TLD) is an “encrypted by default” domain extension. This is due to the namespace being inscribed in the HSTS (HTTP Strict Transport Security) Preload List. This list comprises of sites that are hardcoded into Chrome as being HTTPS only. Most major browsers such as Firefox, Opera, Safari and Microsoft Edge have HSTS preload lists based on the Chrome list. As a result the .DEV namespace and .domain is more secure because it is HSTS preloaded.

To ensure .DEV remains a secure and safe namespace, one of the requirements of ownership is that all .DEV domain names are configured to work with an SSL certificate in order for the website to be served over HTTPS. When you get your domain from us, you receive unlimited SSL certificates for maximum security. For more information about configuring HTTPS, including how to setup your SSL certificate, please view our FAQ.

Get your .DEV domain today and ensure that your website, blog, or development code has the safest, most secure home on the Internet.

Thankyou!CHARLES

  • Fantastic service, very quick to respond and never feel like I'm being rushed. Konor most recently helped me to setup my account in no time at all and was very helpful to explain the services in detail. Highly Recommend.Darren

  • We have now been happy YAY.COM customers for nearly a year. Everything about their service is recommendable. Setup went smoothly with plenty of friendly skilled support from Various tech support staff. Since switching to YAY.COM our telecoms costs have halved. The couple of times since then that we've contacted them for support they've sorted the problem quickly and helpfully, including the other day when I phoned to ask for their help with a problem with our phone line provider - so not a YAY.COM problem - and they came through for us quickly and efficiently. Can't fault them!Richard

  • A quick response getting straight to the issue of the protocol and illustrated how to change the settings on the handset and YAY dashboard, getting us back online quicklyRob

  • Really, really impressed. Sensible, polite people who quickly solved my problem - and phone answered quickly -what's not to like. If only all telecoms providers were this easy to do business with.Simon

  • Excellent service over the phone, calls are answered promptly by individuals who clearly understand the technology, and who quickly get to the bottom of issues with simple easy to understand resolutions. I wish all the providers I dealt with were as efficient as this!Jim

  • Yay are consistently flawless. As a small but expanding ISP, we chose Yay to provide a reliable and feature-rich VoIP service to accompany our fibre-to-the-home broadband service. Yay offers all the flexibility that we needed in terms of product features, ease of use, compatibility with SIP endpoints and convenient API access to control all areas of one's account. Their support team is what really sets them apart from the competition. Any query is dealt with quickly and efficiently and almost always by the first person that you speak to, all of the team are so knowledgeable in all areas and can resolve or advise on any questions themselves without needing to put you on hold or escalate to anyone else. We're confident that Yay will continue to meet our needs as we expand to hundreds and eventually thousands of customers.Robert

  • Every-time I speak with the Yay support team I am blown-away by their excellent work. Nothing is too much trouble and their product knowledge if second to none. I wish all companies support staff were like this! One very happy customer here! Ben
