7 Website Security Tips Every Small Business Should Follow

Small businesses are attractive targets for cybercriminals precisely because they're less likely to have dedicated security teams or monitoring tools. But most website attacks are opportunistic — automated bots scanning for known weaknesses, not targeted hacks. That means following a few basic security practices is enough to avoid the vast majority of threats.

1. Keep Your CMS and Plugins Updated

If your website runs on WordPress, Shopify, Squarespace, or another content management system, keeping it updated is the single most impactful thing you can do for security. Most successful website compromises exploit known vulnerabilities in outdated software — vulnerabilities that were patched months or years ago.

Enable automatic updates where possible, and make a habit of logging into your CMS dashboard every couple of weeks to check for pending plugin or theme updates. Plugins with no recent updates and a small user base are worth replacing.

2. Use Strong, Unique Passwords

Weak or reused passwords are responsible for a significant proportion of website compromises. Use a password manager (1Password, Bitwarden, or your browser's built-in manager) to generate and store unique passwords for your CMS, hosting account, domain registrar, and email.

Enable two-factor authentication (2FA) wherever it's available — especially for your hosting control panel and any admin accounts. Even a weak password becomes much harder to exploit when 2FA is active.

3. Enforce HTTPS Across Your Entire Site

HTTPS encrypts the connection between your website and your visitors, protecting any data they submit — contact forms, login details, payment information. Check that your SSL/TLS certificate is valid and not approaching expiry, and that every page on your site redirects HTTP requests to HTTPS automatically.

Also check for "mixed content" — pages that load over HTTPS but pull in images, scripts, or stylesheets over insecure HTTP. Mixed content warnings erode visitor trust and can expose data. Your browser's developer tools will flag these.

4. Set Security Headers

HTTP security headers are instructions your web server sends to browsers, telling them how to handle your site. They protect against a range of attacks including cross-site scripting (XSS), clickjacking, and protocol downgrade attacks. The most important ones are:

• Strict-Transport-Security — forces browsers to use HTTPS for future visits
• Content-Security-Policy — controls which scripts and resources can load on your pages
• X-Frame-Options — prevents your site being embedded in iframes (clickjacking)
• X-Content-Type-Options — stops browsers guessing file types in ways that can be exploited

Missing security headers are one of the most common findings in a website security scan, and they're usually fixable in a few lines of configuration.

5. Monitor for Data Breaches

Billions of email addresses and passwords have been leaked in data breaches over the past decade. If any of your team use a work email address on external services — and almost everyone does — there's a real chance those credentials have been exposed.

Attackers use leaked credentials in "credential stuffing" attacks, trying username/password combinations against your website admin panel, hosting account, and other services. Running a data breach scan on your domain tells you which email addresses have been compromised and what information was exposed, so you can force password resets and take appropriate action.

6. Back Up Regularly

Backups don't prevent attacks, but they dramatically reduce the impact of one. If your site is compromised or corrupted, a recent backup means you can restore it quickly without losing data or paying a ransom.

Most hosting providers offer automatic daily or weekly backups — confirm yours is enabled and working. Store at least one copy of your backup off-site (in cloud storage separate from your hosting account) so that a compromised host doesn't also mean a compromised backup.

7. Scan Your Website Regularly

Security is not a one-time task. New vulnerabilities are discovered continuously, software updates can introduce new issues, and your site configuration may drift over time. Running a security scan every month or two ensures you catch problems early — before they're exploited.

A good security scanner checks SSL certificates, security headers, HTTPS enforcement, cookie security, server information leakage, and more — giving you a score out of 100 with plain-English explanations and specific fixes. It takes under a minute and costs far less than recovering from a breach.
