Advanced security for your users

We bake security in to every layer of our hosting with features such as brute-force login protection, IP address block managers, permissions checkers, website password managers and web application firewalls all included for free. This enterprise-level protection covers you against DDoS attacks and much more.

We achieve our 99.99% uptime target by ensuring our storage is resilient to the level that entire servers could be lost, and multiple disks can fail, all with no downtime to our customers. We also take daily backups off-site for extra protection at no extra cost to yourself. Just in case.

Roundcube Hosting FAQs

Is it easy to install Roundcube?

Installing Roundcube on 20i is very easy as Roundcube is available as a one-click install app within My20i, so you can be up and running in minutes.

Yes! Upgrading or downgrading is quick, easy and can be done any time from within the My20i control panel.

Our dedicated Migration Centre can easily migrate your platform from other web hosts. Migrate in minutes, not hours or days, and preserve all emails, folders, files, scripts, databases and other data exactly as they are. There are no limits to the migration service - which is completely free to use. We’re also on hand to help at any time.

We have multiple data centres in the UK and the USA. You can choose to have your platform hosted in the UK or USA when you set up your hosting, so your inboxes will update quickly for everyone.
