Fixing Insufficient Transport Layer Security (TLS) in Laravel
Transport Layer Security (TLS) ensures that data exchanged between a client and a server is encrypted and secure. Insufficient TLS configurations in Laravel applications can expose sensitive data to attackers, leading to severe security vulnerabilities. This guide will explain how to identify and resolve TLS issues in Laravel using coding examples and tools, including our free Website Security Scanner tool.
What Is Insufficient TLS?
Insufficient TLS refers to weak or misconfigured security protocols, ciphers, or certificates used for HTTPS connections. This can lead to:
- Man-in-the-middle (MITM) attacks
- Sensitive data exposure
- Downgrade attacks (e.g., SSL Strip)
Common Causes of Insufficient TLS in Laravel
- Using outdated TLS versions (e.g., TLS 1.0 or 1.1).
- Misconfigured SSL/TLS certificates.
- Using weak cipher suites.
- Not enforcing HTTPS connections.
Detecting TLS Issues
Use Our Free Security Tool
Start by running a vulnerability scan of your Laravel application using our Website Security Checker tool. This tool will provide a detailed report highlighting your app's TLS issues.

Fixing TLS Issues in Laravel
1. Enforce HTTPS Connections
Enable HTTPS by redirecting all HTTP requests to HTTPS in your AppServiceProvider
or .htaccess
file.
Code Example: Using Middleware
// In app/Http/Middleware/ForceHttps.php
namespace App\Http\Middleware;
use Closure;
class ForceHttps
{
public function handle($request, Closure $next)
{
if (!$request->secure()) {
return redirect()->secure($request->getRequestUri());
}
return $next($request);
}
}
// Register middleware in Kernel.php
protected $middleware = [
\App\Http\Middleware\ForceHttps::class,
];
2. Use Strong TLS Protocols
Update your web server configuration to use only secure protocols (TLS 1.2 or higher) and strong cipher suites.
For Apache (httpd.conf):
SSLProtocol All -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
SSLCipherSuite HIGH:!aNULL:!MD5
For Nginx (nginx.conf):
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers HIGH:!aNULL:!MD5;
3. Implement HTTP Strict Transport Security (HSTS)
Add HSTS headers to ensure browsers only connect to your app over HTTPS.
Code Example: Using Middleware
// In app/Http/Middleware/SecurityHeaders.php
namespace App\Http\Middleware;
use Closure;
class SecurityHeaders
{
public function handle($request, Closure $next)
{
$response = $next($request);
$response->headers->set('Strict-Transport-Security', 'max-age=31536000; includeSubDomains');
return $response;
}
}
// Register middleware in Kernel.php
protected $middleware = [
\App\Http\Middleware\SecurityHeaders::class,
];
Validating Your Fixes
Once you have applied these changes, rerun a security scan using our tool to Check Website Vulnerability. The vulnerability assessment report will confirm if your TLS configurations are secure.

Bonus: Testing TLS in Laravel Using Code
If you need to programmatically test your Laravel app's TLS configuration, you can use curl
with PHP to verify that only HTTPS is allowed.
Code Example: Testing HTTPS
$url = "https://yourdomain.com";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
if ($info['http_code'] == 200) {
echo "HTTPS is working correctly!";
} else {
echo "TLS issues detected. Please review your setup.";
}
Final Thoughts
Securing your Laravel application starts with configuring strong TLS protocols and enforcing HTTPS. By following the steps above and leveraging our tool to test website security free, you can ensure that your application is protected against insufficient TLS vulnerabilities.
Remember: Cybersecurity is an ongoing process. Regularly monitor your app's security posture and update your configurations to meet the latest standards.
