Securing a website doesn't have to be complicated. A handful of basic measures cover the vast majority of common threats. Let's look at three layers that should not be missing from any project — and which you largely get for free from a good host.
An SSL certificate as a given
An encrypted connection over HTTPS is now the standard, not a premium. Quality hosting offers a free Let's Encrypt certificate with automatic renewal. Without SSL, browsers and search engines penalise you and visitors lose trust. You usually don't need to pay for a certificate — a paid one only makes sense in specific cases, such as large companies wanting a premium warranty.
Automatic backups
A backup you have to run manually will sooner or later be missing. Look for hosting with daily automatic backups and, above all, one-click quick restore. Test the restore before you need it for real — a backup you've never restored from isn't a backup. How often to back up by site type and how to verify the restore is covered in How often to back up your website.
The 3-2-1 rule
For important projects, keep three copies of your data on two different media and one off the host. Even if the provider backs up, your own copy protects you against an outage on their side. It's also safer to use storage that an attacker can't reach with the same credentials as the site — otherwise they could wipe the site and the backup at once.
Two-factor authentication
A password alone isn't enough. Enable two-factor authentication (2FA) everywhere you can — in the hosting admin, in WordPress and with your domains. It's the most effective defence against a leaked password being abused, and it takes a few minutes. Combined with a strong, unique password (ideally from a password manager), you close the door on the vast majority of automated attacks, which rely precisely on weak and reused passwords.
Firewall and attack protection
Beyond the three basic layers, it helps to know what the host does on its side. A quality provider runs a firewall that filters out common malicious requests, and often DDoS protection against attacks that try to flood the site with traffic. On WordPress, a security plugin that watches logins and blocks repeated password-guessing attempts helps too. None of these measures is hard to deploy, and together they make the site a far tougher target.
Updates are half of security
Most successful attacks don't exploit a clever trick but an old, well-known hole in an unpatched system, theme or plugin. Regular updates are therefore an unglamorous but perhaps the most effective layer of protection. This is doubly true if you run your own server: on shared hosting the provider handles server security and you look after the site itself, whereas on an unmanaged VPS updates and the firewall are entirely on you, as we cover in Managed vs unmanaged VPS.
Personal data and GDPR
If your site collects any data from visitors — registrations, orders, a contact form — you're handling personal data and GDPR rules apply to you. In practice that means not just an encrypted connection and secure storage, but also knowing where the data physically sits. Some providers keep their servers within the EU, which simplifies the paperwork around data protection. Don't forget the same rules apply to backups — they too are a copy of personal data and belong on secure storage.
The specific procedures around backups, including how often to back up and how to verify the restore, are covered in the separate article How often to back up your website. Security and backups are closely linked — a good backup is the last safety net when everything else fails. No protection is one hundred percent, which is exactly why the ability to quickly restore from a backup is what decides whether an incident becomes a brief nuisance or days of lost work. Once you set up these three layers — SSL, backups and 2FA — properly, you've covered the essentials and a good host largely takes care of the rest.
