Why Does My Website Say Not Secure? Causes & Easy Fixes

You open your website, only to see a warning: “Not Secure.” Instantly, you wonder—what does this mean, and is your site at risk?

This nagging message can make visitors think twice before trusting your site, impacting your credibility and even your business. Understanding why this warning appears is crucial for keeping your website safe and professional.

In this article, we’ll explain exactly why your site shows as “Not Secure” and walk you through simple steps to fix it.

Why Does My Website Say ‘Not Secure’?

Seeing a “Not Secure” warning on your website can be alarming, both for you and for your visitors. This warning signals that the connection between your site and its users isn’t properly protected, putting private information at risk. Understanding why this message appears and how to resolve it is crucial for earning visitor trust, securing your website, and staying competitive online.

Let’s explore what “Not Secure” really means, why it happens, how you can fix it, and practical steps to maintain a secure online presence.

Understanding the “Not Secure” Warning

When a browser (like Chrome, Firefox, or Edge) says your website is “Not Secure,” it’s warning people that the site isn’t using HTTPS—a secure protocol—instead of HTTP. This means:

Any data (personal details, passwords, payment information) sent between your site and its visitors could be intercepted.
Browsers highlight the warning to shield users from potential threats.
Over time, many browsers have become increasingly strict, making these warnings more frequent and noticeable.

The Difference Between HTTP and HTTPS

HTTP (HyperText Transfer Protocol): The basic way web browsers communicate with websites. However, all information is sent in plain text, making it easy for attackers to intercept.
HTTPS (HyperText Transfer Protocol Secure): Adds a layer of security through encryption, using SSL/TLS certificates, so information sent between the site and visitors is scrambled—inaccessible to prying eyes.

Common Reasons Your Website Shows ‘Not Secure’

Let’s break down why your website might be flagged by browsers:

No SSL Certificate Installed
SSL (Secure Sockets Layer) certificates authenticate your website’s identity and enable encrypted connections.
Without it, browsers can’t establish a secure link.
Expired or Invalid SSL Certificate
SSL certificates aren’t set-and-forget. They expire (often after a year or two).
If yours lapses or is misconfigured, security warnings appear.
Mixed Content on Your Site
Even with HTTPS, if your site loads some resources (like images, scripts, or stylesheets) over HTTP, browsers alert users that parts of the page aren’t secure.

Non-secure Links or Forms
If a form submits data over HTTP or links send users to unsecured pages, the browser may display a “Not Secure” message.
Subdomains Without Proper SSL
Your main domain may be secured, but subdomains (like shop.yoursite.com) also need valid SSL certificates.

Why Site Security Matters

Ignoring these warnings turns visitors away, impacts your reputation, and can threaten your website’s success:

Loss of Trust: Customers hesitate to share information—hurting sign-ups and sales.
Search Engine Rankings: Google and other search engines factor security into search ranking; non-secure sites drop lower.
Legal and Compliance Issues: Privacy regulations might require encrypting user data.

How to Fix the ‘Not Secure’ Website Warning

If your website is showing this warning, here’s how you can solve the problem and keep your visitors safe.

1. Install an SSL Certificate

SSL certificates are available from many providers and web hosts:

Contact Your Hosting Provider: Companies like GoDaddy, Bluehost, and Namecheap usually offer easy SSL integration.
Choose the Right Certificate: For most small and medium sites, a basic Domain Validated (DV) SSL certificate is enough. Larger businesses may need Organization Validated (OV) or Extended Validation (EV) certificates.

2. Activate and Configure HTTPS

After installing an SSL certificate:

Update Site Links: Make sure all website links point to https:// instead of http://.
Redirect Traffic: Set up automatic redirects from HTTP to HTTPS so visitors always use the secure version.

3. Fix Mixed Content Errors

This step often gets overlooked:

Scan Your Website: Check for elements like images, scripts, or CSS files loading over HTTP.
Update URLs: Replace them with their HTTPS versions or host them securely on your server.

4. Renew SSL Certificates Regularly

Don’t let your certificate expire:

Set Reminders: Most providers send advance notifications before expiry.
Automate Renewal: Some hosts offer automatic SSL renewal, reducing the risk of accidental expiration.

5. Secure All Subdomains and Web Pages

If your website has several subdomains or sections:

Use a Wildcard SSL if Needed: Covers all subdomains in one certificate.
Double-check Forms: Make sure any forms or payment gateways always use HTTPS.

6. Test and Monitor Your Website

Stay vigilant:

Use Online Tools: Scan your website for vulnerabilities or misconfigurations.
Regularly Check for Browser Warnings: Visit your site in multiple browsers and devices.

Practical Tips and Best Practices

To keep your website secure and user-friendly, follow these simple practices:

Choose Reputable SSL Providers: Opt for well-known companies to avoid compatibility issues.
Use Content Management Systems (CMS) Wisely: If you use platforms like WordPress, install plugins or add-ons that help manage SSL and force HTTPS.
Inform Users: Let your audience know you value their security for added trust.
Keep Everything Updated: From CMS and plugins to SSL certificates—updates patch security holes.
Avoid Self-Signed Certificates for Public Sites: While free, these are unreliable and often trigger warnings.

Common Benefits of Securing Your Website

Upgrading your site’s security offers tangible advantages:

Builds Confidence: Visitors see HTTPS and a padlock—signals that their data is safe.
Improves Search Rankings: Secure sites are favored by search engines.
Prevents Data Theft: Encryption blocks hackers from reading sensitive information.
Prepares for Future Regulations: Stay ahead of privacy and data laws.

Challenges With Website Security (And How to Overcome Them)

Some hurdles you might encounter include:

Cost Concerns: While premium SSL certificates can be costly, many hosts now provide free basic SSL options.
Technical Knowledge: Not everyone is a web expert, but most hosts offer step-by-step guides and customer support.
Hidden Mixed Content: Finding every insecure link can be tedious; automated scanning tools can help.
Renewal Hassles: Forgetting to renew SSL certificates is common; enable auto-renew where possible.

Cost Tips: Getting Secured Without Breaking the Bank

Worried about the expense? Here’s what you can do:

Look for Hosting Plans With Free SSL: Many major hosting providers include free Let’s Encrypt SSL certificates.
Compare Certificate Types: Basic DV SSLs are often cheaper (or free) than EV certificates, which are typically only necessary for high-profile businesses.
Automate Where Possible: This saves money on maintenance and reduces downtime.
Shop Around: SSL prices vary—reputable resellers often have competitive rates.
Use Online Tools: Many security scanning tools are free and help you maintain security without added cost.

Summary

A “Not Secure” warning on your website isn’t just a technical issue—it’s a risk to your reputation and visitor safety. The most common cause is the lack of a properly installed SSL certificate, or misconfigured secure connections. By addressing these issues, routinely checking for problems, and following industry best practices, you can keep your website safe, maintain trust, and build a stronger online presence.
