Web Security Is Critical in 2025

Cyberattacks against websites increased by 38% in 2024 according to recent security reports. At Lueur Externe, security is built into every web project from the design phase. A compromised website can lead to data loss, SEO ranking drops, and lasting damage to your business reputation.

Security is not a luxury reserved for large enterprises. Every website, regardless of size, is a potential target for automated attackers exploiting known vulnerabilities.

HTTPS and SSL Certificates

HTTPS has become the absolute standard. Google Chrome displays a warning for unsecured sites, and HTTPS is a confirmed ranking factor. Lueur Externe systematically deploys SSL certificates on every website we develop.

Essential points to verify:

  • Valid and properly configured SSL certificate
  • Automatic HTTP to HTTPS redirection
  • HSTS (HTTP Strict Transport Security) headers enabled
  • Automatic certificate renewal via Let’s Encrypt or equivalent

Protection Against Common Vulnerabilities

The OWASP Top 10 identifies the most critical vulnerabilities. In 2025, the main threats include:

  • SQL injection and XSS: validate and sanitize all user inputs server-side
  • Broken authentication: implement multi-factor authentication and robust password policies
  • Sensitive data exposure: encrypt data at rest and in transit
  • Security misconfiguration: disable unnecessary features and detailed error pages

Lueur Externe applies OWASP recommendations in every development project and conducts regular security audits.

CMS Security and Updates

CMS platforms like WordPress represent a significant share of websites and are prime targets. Most compromises stem from outdated plugins or themes. A rigorous update policy is essential.

We recommend keeping the CMS and all plugins up to date, removing unused extensions, limiting administrative privileges, and implementing daily automated backups.

HTTP Security Headers

HTTP security headers provide an often-overlooked additional layer of protection. Essential headers include Content-Security-Policy to prevent XSS attacks, X-Frame-Options to block clickjacking, and Permissions-Policy to control access to browser features.

Monitoring and Incident Response

Early detection of security incidents is crucial. Lueur Externe implements monitoring systems that alert in real time when suspicious activity is detected. A documented incident response plan enables rapid reaction and minimizes the impact of any potential compromise.

Web security is a continuous process, not a fixed state. Investing in your website’s protection means safeguarding your business and your customers’ trust.
