Website security best practices sound like something only an IT department worries about — but most of them are simple habits any business owner can follow. Here is the reassuring part: most website hacks are not the work of a genius targeting your business specifically. They are automated bots scanning millions of sites for easy, unlocked doors, which means a few sensible website security best practices put you out of reach of the vast majority of attacks. You do not need to be an expert; you need a handful of habits.
1. Keep Everything Updated
This is the single most important one. Outdated software — WordPress core, plugins, themes — is the number-one way sites get hacked, because attackers specifically target known holes in old versions. Applying updates promptly closes those holes. If you are nervous about updates breaking the site, that is a fair concern (it happens), which is exactly why doing them carefully with a backup first matters.
2. Use Strong, Unique Logins
Never use “admin” as your username or a weak password. Use a long, unique password (a password manager makes this painless), and turn on two-factor authentication so a stolen password alone is not enough to get in. Limit how many people have admin access, and remove accounts for anyone who no longer needs them.
3. Always Have a Recent Backup
Security is not only about prevention — it is about recovery. If the worst happens, a recent off-site backup turns a disaster into a quick restore. Automate it and keep the copies somewhere separate from the site. Our guide on how to back up a WordPress website covers doing this properly.
4. Install SSL (HTTPS)
An SSL certificate encrypts data between your site and its visitors, shows the padlock in the browser, and is expected by both customers and Google — a site without it is flagged “Not secure.” Most hosts provide free SSL; make sure yours is active. See how to add an SSL certificate to your website if you are not sure.
5. Use a Security Plugin and Monitor
On WordPress, a reputable security plugin adds a firewall, blocks brute-force login attempts, and scans for malware. Combined with monitoring — so you actually find out quickly if something is wrong rather than discovering it weeks later — this covers the gaps the first four steps leave.
6. Choose Good Hosting
A quality host provides server-level security, isolation from other sites, and quick support if something goes wrong. Cheap, overcrowded hosting is a common weak point. This is one reason hosting choice matters beyond just speed.
The One That Matters Most
If you only do one thing from this list, keep everything updated. Industry data year after year points to outdated plugins and themes as the leading cause of compromised WordPress sites — far ahead of “clever” attacks. Strong passwords and SSL matter, but an un-updated site is the unlocked door bots are actively looking for. Everything else on this list reduces risk; updates remove the most common cause of it entirely.
How Often Should You Review This?
Security is not a one-time setup — it is upkeep. Updates should be applied at least monthly (more often for a busy or ecommerce site). Passwords and user accounts are worth reviewing every few months: remove people who have left, and rotate any password that might have been shared. Backups should be running automatically and — crucially — actually tested once in a while, because an untested backup is only a hope. If keeping to that rhythm sounds like one more thing you will forget, that is precisely what a maintenance plan exists to handle: it runs quietly in the background so security does not depend on you remembering.
If You Have Already Been Hacked
Prevention is these six habits; recovery is different. If your site is already compromised — redirecting visitors, showing spam, or flagged by Google — the priority is a proper cleanup that removes the malware and closes the backdoor, which our malware removal service handles. For ongoing protection afterwards, our website security maintenance keeps these practices running so you do not have to think about them.
Want your site kept secure without becoming a security expert yourself? Our website security maintenance handles updates, hardening, backups, and monitoring every month. It is also part of our ongoing website maintenance if you would rather have everything in one place. Message us on WhatsApp.
