6 Ways To Make Sure Your Website Is Secure for Customers

Most people still associate website security with a padlock icon in the browser. That padlock is gone from Google Chrome — replaced in 2023 with a neutral “tune” icon — and even when it was there, it only confirmed one thing: the connection was encrypted. It said nothing about whether the business behind the URL was honest, registered, or real.

Knowing how to tell if a website is secure matters whether you’re a shopper checking an unfamiliar retailer or a business owner responsible for protecting customer data. The signals have changed, the threats have evolved, and the old advice no longer holds up.

This guide covers what browser security indicators actually mean in 2026, why a “secure” label can appear on a fraudulent site, and the practical checks UK users and business owners should run before trusting any website with personal or payment information.

Encryption vs. Legitimacy: Why “Secure” Doesn’t Mean Safe

This is the most important distinction in website security, and most guides still get it wrong.

When a browser shows a security indicator, it confirms that the data travelling between your device and the server is encrypted. Nobody sitting on the same network can intercept your login details or card number in transit. That is useful. It is not the same as guaranteeing the website is run by a trustworthy organisation.

How Scammers Use Free SSL Certificates

Free SSL certificates, issued by services such as Let’s Encrypt, are legitimate tools that any site owner can obtain in minutes at no cost. They encrypt the connection. They do not verify who owns the site or whether the business exists.

A phishing site mimicking a bank or retailer can carry a valid SSL certificate and trigger no browser warnings at all. The connection is encrypted. The business is fraudulent. This combination is now standard practice among more sophisticated scammers.

What “Secure” Actually Confirms

When a browser indicates a site uses HTTPS, it tells you three things: the connection is encrypted, the domain you’re viewing matches the certificate, and the certificate was issued by a recognised authority. It tells you nothing about the site owner’s identity, the accuracy of their claims, or whether the business is registered and operating legally.

Ciaran Connolly, founder of Belfast digital agency ProfileTree, puts it plainly: “We tell clients that HTTPS is the floor, not the ceiling. Every site we build uses it. But a site without HTTPS is obviously risky — and a site with HTTPS is simply meeting the minimum standard.”

Visual Indicators: What Your Browser Actually Shows in 2026

The landscape changed significantly in 2023 when Google Chrome removed the padlock icon from its address bar. Most articles published before 2024 still reference the padlock as the primary trust signal. It is no longer there.

The Chrome “Tune” Icon

Chrome now displays a small “tune” icon (two horizontal sliders) to the left of the URL. Clicking it opens a panel showing connection details, cookie permissions, and site-specific settings. For HTTPS sites, the connection status shows as “Connection is secure.” For HTTP sites, Chrome shows “Not secure” in the address bar with a warning icon.

The reasoning behind the change: Google’s own research found that users interpreted the padlock as meaning the site was “safe” in a broader sense. The tune icon is deliberately neutral to avoid that false assurance.

Security Indicators in Safari and Edge

Safari uses a padlock icon in its address bar, but only shows it when a site uses a valid HTTPS certificate. Tapping or clicking it on mobile reveals certificate details. A missing padlock in Safari indicates an unencrypted HTTP connection.

Microsoft Edge shows a padlock for secure connections and “Not Secure” for HTTP pages, similar to the older Chrome behaviour. On mobile, both browsers flag insecure connections more prominently than their desktop counterparts, which matters since most UK users browse primarily on phones.

On any browser, if the address bar shows “Not Secure” or displays a warning triangle, do not enter personal details, passwords, or payment information on that page.

Technical Tools to Verify a URL

Beyond browser indicators, several free tools let you investigate a site’s security posture before interacting with it.

Google Safe Browsing: Google’s transparency report at transparencyreport.google.com/safe-browsing/search lets you check whether a URL has been flagged for malware, phishing, or unwanted software. It updates frequently and is one of the most reliable free checks available.

VirusTotal: Paste any URL into VirusTotal, and it runs the address through 70+ security engines simultaneously. It flags known malware distribution sites, phishing pages, and suspicious redirects. Useful for links received in emails or messages.

SSL Checker tools: Sites like SSL Labs (from Qualys) provide a detailed SSL certificate analysis for any domain, including certificate validity dates, issuing authority, and whether the configuration has known vulnerabilities. This is more relevant for developers and site owners than general users.

WHOIS lookup: Checking a domain’s registration details via Nominet (for .co.uk domains) or a general WHOIS service can reveal when a domain was registered. Scam sites are often registered days or weeks before a campaign runs. A domain registered last month that sells electronics at heavily discounted prices is a red flag.

Five Red Flags of a Fraudulent Website

Even a site with valid HTTPS and a clean Google Safe Browsing result can be fraudulent. These signals go beyond the connection layer and look at the business behind the URL.

Domain Name Discrepancies

Typosquatting is the practice of registering domains that closely mimic legitimate ones: amaz0n.co.uk, paypal-secure.com, bankofireland-login.net. Always check the full domain in the address bar, not just the site’s visual branding. Legitimate UK banks, retailers, and government services use their established primary domains and do not redirect you through subdomains or hyphenated variations.

Pricing That Defies Reason

Fraudulent e-commerce sites routinely list branded goods at 60–80% below retail price. If a site is selling an item that retails at £300 for £45, the goods either do not exist or are counterfeit. Cross-reference prices on the manufacturer’s site and established UK retailers before purchasing from an unknown domain.

Missing or Generic Legal Pages

Every UK website that collects personal data must display a Privacy Policy and comply with UK GDPR. Check the footer for Privacy Policy, Terms and Conditions, and a Returns Policy if it is an e-commerce site. Absence of these pages, or pages that are clearly copied boilerplate without the company name filled in, is a significant warning sign. Our guide to GDPR-compliant web forms covers what compliant data collection looks like on legitimate UK sites.

No Verifiable UK Contact Details

Legitimate UK businesses typically display a physical address, a UK phone number, and a contact email. Check the address against Google Maps. Search the company name on Companies House at find-and-update.company-information.service.gov.uk. Any UK limited company is legally required to be registered there. If the name does not appear, the company may be operating as a sole trader — which is legitimate — or the name may be entirely fabricated.

No Credible Review History

Check Trustpilot, Google Reviews, and sector-specific review aggregators. Look not just at the score but at the volume and recency of reviews, and whether negative reviews receive responses. A site with 10 five-star reviews, all posted within a fortnight of launch, warrants caution. Legitimate businesses accumulate reviews over time with natural variation.

Website Security for Business Owners: What Your Site Must Have

If you run a UK business website, the security obligations run in both directions. Your visitors need to trust your site, and you have legal obligations around how you handle their data.

HTTPS Is Non-Negotiable

Every UK business website should use HTTPS. Beyond the security argument, Google has used HTTPS as a ranking signal since 2014, and Chrome actively labels HTTP sites as “Not Secure.” Any web development agency worth working with will configure HTTPS as standard. Our web development services in Belfast include SSL configuration and ongoing security monitoring for every site we build.

Keep CMS Software and Plugins Updated

The majority of WordPress site breaches occur through outdated plugins or themes with known vulnerabilities. WordPress itself issues security updates regularly. Running outdated versions is the equivalent of leaving a known unlocked door in a building. Set updates to apply automatically where possible, and audit your plugin list quarterly to remove any unused plugins. For guidance on what a properly configured WordPress installation looks like, see our overview of WordPress for business websites.

Validate Both Browser-Side and Server-Side

Input validation prevents malicious code from being injected through your forms and comment fields. Browser-side validation catches simple errors before submission. Server-side validation is the security layer that actually matters, because browser-side checks can be bypassed by anyone with basic technical knowledge. Our guide to server-side and client-side programming explains the distinction in practical terms.

Protect Against Cross-Site Scripting

XSS attacks inject malicious JavaScript into your pages through unsanitised user input, such as comment fields or search boxes. The injected script then runs in visitors’ browsers, potentially stealing session cookies or redirecting users to phishing pages. Using a Content Security Policy (CSP) header limits which scripts can execute on your pages, significantly reducing this attack surface.

Error Messages and Data Handling

Error messages should tell users something went wrong without revealing technical details about your server, database structure, or software stack. Full exception details in public-facing error messages hand attackers a detailed map of your system. Log errors server-side and show users only a generic message. For businesses handling customer data, understanding your obligations under UK GDPR is essential — our data privacy guide for e-commerce covers the key requirements for UK-based online retailers.

What to Do if You’ve Used an Unsecure or Fraudulent Site in the UK

If you’ve entered personal or financial details on a site you now believe was fraudulent, act quickly.

Contact your bank or card provider immediately to flag the transaction and request a chargeback if a payment was made. Banks have dedicated fraud teams and are generally obliged to investigate unauthorised transactions.

Report the site to the National Cyber Security Centre (NCSC) at report.ncsc.gov.uk. The NCSC operates the Active Cyber Defence programme and can take down malicious UK-hosted sites. For scam sites in general, the reporting route is Action Fraud at actionfraud.police.uk, which is the UK’s national reporting centre for fraud and cybercrime.

If the site was impersonating a specific brand or business, report it directly to that business too. Most major retailers and financial institutions have dedicated phishing or fraud reporting channels.

Change any passwords you used on the site, and if you reuse passwords across sites (which you should not), change those too.

Your 60-Second UK Website Security Check

Before entering personal details on an unfamiliar site, run through this checklist:

The URL in the address bar matches exactly what you expected, with no extra hyphens, numbers replacing letters, or unfamiliar subdomains. The address begins with HTTPS and your browser shows no “Not Secure” warning. The site has a Privacy Policy and Terms and Conditions in the footer. A UK address and contact number are listed and verifiable. The company appears on Companies House if it claims to be a registered UK limited company. Prices are consistent with what you’d find from established retailers. Reviews on independent platforms such as Trustpilot look genuine, varied, and accumulated over time.

If any of these checks fail, do not proceed with a purchase or data entry until you’ve investigated further.

Protecting Your Business Website: Where to Start

If you run a website, security is your responsibility as much as your hosting provider’s. Start with the basics: HTTPS configured correctly, CMS software and plugins kept up to date, and input validation applied on both the browser and server side. These three measures address the majority of common vulnerabilities on small business sites.

Beyond the technical foundations, make sure your site displays the legal pages UK visitors expect — a Privacy Policy, Terms and Conditions, and a clear contact address. These are not just trust signals for users; they are legal requirements under UK GDPR for any site collecting personal data.

When to Bring in Professional Help

Some security requirements go beyond what most business owners can reasonably manage alone. If your site handles payment data, stores customer accounts, or operates in a regulated sector, a professional security audit is worth the investment. An audit identifies vulnerabilities before attackers do, checks your SSL configuration, reviews your data handling practices, and flags anything that could expose you to a breach or a regulatory penalty.

ProfileTree’s web development team in Belfast works with businesses across Northern Ireland, Ireland, and the UK on site builds that include security configuration from the ground up. If your current site needs a review rather than a rebuild, that’s a straightforward starting point too.

Building Customer Trust Through Visible Security

Security that works behind the scenes only delivers its full value when customers can see evidence of it. A site that is technically secure but gives visitors no reassurance will still lose them at the point of purchase or enquiry.

Visible trust signals matter most on pages where users are asked to share data: contact forms, checkout pages, account registration, and booking systems. Displaying your UK business address, a verifiable phone number, and links to your Privacy Policy and Terms in the footer costs nothing and removes hesitation. On e-commerce pages, showing accepted payment methods and any relevant trust badges near the call to action reinforces that the transaction is handled professionally.

Review platforms add a layer of third-party validation that no amount of on-site copy can replicate. A consistent presence on Google Reviews or Trustpilot, with responses to both positive and negative feedback, signals that a real business is operating behind the site. For ProfileTree clients, we include guidance on review strategy as part of our website launch process, because a technically sound site that launches without a trust-building plan misses half the picture.

The distinction worth keeping in mind: security protects your customers, but visible trust signals convert them. Both need attention.

Conclusion

Website security in 2026 comes down to two separate questions: is the connection encrypted, and is the business behind it legitimate? HTTPS answers the first. The checks in this guide answer the second. For UK businesses, getting both right protects customers, satisfies GDPR obligations, and builds the kind of trust that keeps people on your site. If you’re unsure whether your current site meets the standard, speak to the ProfileTree team about a security review.
