Is Your Website Secure?

If someone told you your shopfront had a broken lock, you would fix it today. Your website works the same way, except the door is open to the entire internet, and most business owners have no idea whether theirs is locked.

These are the basics every website should have. Most are missing them, and your customers notice more than you think.

SSL: The Padlock in Your Browser

SSL (Secure Sockets Layer) encrypts everything that travels between your visitor's browser and your website. When it is active, all data in transit is protected. When it is missing, anyone on the same network (a coffee shop, an airport, a shared office) can read every form submission, every password, every message your customers send.

You can check this yourself. Look at your website URL in the browser. If it starts with https:// and shows a padlock icon, SSL is active. If it says http:// with no padlock, or worse, a “Not Secure” warning. Your visitors can see it too.

The good news: SSL certificates are free through services like Let's Encrypt and Cloudflare. Every website should have one, and in 2026 there is zero excuse to go live with an unencrypted connection.

Security Headers: The Invisible Shield

Every time someone visits your website, your server sends back a set of instructions called “headers.” Most websites only send the basics: here is the page, here is the content type. But there is a set of security headers that tell the browser how to protect your visitors, and the majority of small business websites are missing all of them.

Here is what a properly secured site sends versus what most do not:

Now here is what the same audit looks like on a typical small business website built with a template or page builder:

Contact Forms: The Front Door for Attackers

If your website has a contact form, it is the most common entry point for abuse. A form with proper protection handles all of this gracefully. One built carelessly can be used to:

• Flood your inbox with thousands of spam submissions
• Inject malicious code into your database (SQL injection)
• Send phishing emails through your domain (email injection)
• Overload your server with automated requests (DDoS)

A properly built form should have:

// Rate limiting — max 5 submissions per 15 minutes per IP
if (submissions[ip] > 5) return "Too many attempts"

// Honeypot field — hidden from humans, visible to bots
if (form.hiddenField !== "") return silentReject()

// Input sanitisation — strip dangerous characters
const clean = input.trim().slice(0, 1000)

// Email validation — reject malformed addresses
if (!isValidEmail(email)) return "Invalid email"

// Server-side validation — never trust the browser
// Client-side checks are for UX, server-side is for security

Most template-based websites skip all of this. The form sends directly to an email address, wide open. It works fine until someone decides to test it.

HTTPS Redirects: Locking Both Doors

An SSL certificate is a great start. But if your site is still accessible at both http://yourbusiness.com and https://yourbusiness.com, the HTTP version remains exposed. A proper setup forces every request through HTTPS automatically.

# Redirect all HTTP traffic to HTTPS
if (request.protocol === "http") {
  redirect → https://yourbusiness.com + request.path
  status: 301 (permanent)
}

This takes seconds to configure. Combined with the HSTS header mentioned above, it ensures your visitors are always on the encrypted version, even if they type the URL without https.

Third-Party Code: The Risk You Inherit

Every WordPress plugin, every JavaScript library, every analytics script you add to your site is code written by someone else. If that code has a vulnerability, your site inherits it.

This is one of the strongest arguments for hand-coded websites over template builders. A custom-built site runs only the code it needs. Every dependency is deliberate, every library is maintained, and you can account for every line that runs on your server.

Every Flow-Through build follows this principle. You get a clear picture of exactly what code is running and why it is there.

Data Handling: What Happens After They Hit Submit

When a customer fills in your contact form, where does that data go? On a properly built site, the answer is clear: encrypted in transit, validated on the server, stored securely, accessible only to you.

On many small business sites, the picture looks different. Form data travelling over plain HTTP. Submissions sitting in an unencrypted database. Customer email addresses visible in URL parameters. Admin panels accessible at /wp-admin with default credentials still in place.

With the Australian Privacy Act removing the small business exemption from July 2026, how you handle customer data is a legal requirement. Penalties for mishandling personal information can reach $2.5 million for individuals and $50 million for companies.

The Essential Eight and Australian Compliance

The Australian Cyber Security Centre (ACSC) publishes a framework called the Essential Eight: eight mitigation strategies that form the baseline for cyber security in Australia. While the full framework targets enterprise IT environments, several of its principles apply directly to how your website is built and maintained.

Beyond the Essential Eight, Australian businesses also need to consider the Privacy Act 1988 (and its upcoming small business reforms), the Notifiable Data Breaches scheme, and industry-specific regulations depending on your sector.

For most small business websites, the practical takeaway is straightforward: encrypt everything in transit, validate and sanitise all inputs, keep your software updated, restrict who can access the backend, and back it up daily. If your current website ticks all of those boxes, you are in good shape. And if there are gaps, the distance between where you are and where you should be is smaller than you might expect.

The Checklist: Is Your Site Protected?

Here is a quick audit you can run on your own website right now. If you are missing more than two of these, your site has gaps that are worth addressing.

Where to From Here

Every protection listed on this page can be implemented in a day. The real barrier is awareness. Most business owners have never been told what to ask for, and most budget developers only include what you specifically request.

Every Flow-Through build ships with all of this as standard. Security headers, SSL, form protection, server-side validation, clean dependencies, HTTPS enforcement. All included, every time.

Curious where your current site stands? Run it through securityheaders.com and see what comes back. If you want to talk about what it means, get in touch.
