Online security has become a top priority for businesses, especially with the increase in cyber-attacks and online vulnerabilities. In 2025, protecting your website is essential to prevent data theft and hacking, and ensure user confidence.
What are the better ways to secure your website against threats? Here are the best practices to adopt this year.
1. Setting up an SSL certificate for a secure site (HTTPS)
🔒 The HTTPS protocol is now indispensable for any website.
📌 It encrypts data exchanged between the user and the website.
📌 It boosts visitor confidence and improves the SEO referencing on Google.
📌 It is mandatory to comply with data protection standards such as the RGPD.
➡️ Conseil: Check your SSL certificate regularly and renew it before it expires.
2. Use strong passwords and two-factor authentication (2FA)
🔑 Weak passwords are the leading cause of hacking.
📌 Use long, complex passwords (minimum 12 characters).
📌 Activate two-factor authentication (2FA) for an extra layer of security.
📌 Store your passwords securely with a password manager.
➡️ Tip: Avoid using the same password for several accounts.
3. Regularly update your CMS, plugins and themes
🔄 Updates are crucial to correcting security flaws.
📌 Keep your CMS (WordPressJoomla, Drupal, etc.) up to date.
📌 Regularly update your plugins and themes to avoid vulnerabilities.
📌 Remove obsolete or unused extensions to limit risks.
➡️ Conseil: Enable automatic updates for critical security patches.
4. Secure access with a firewall
🛡️ A firewall protects your site from malicious attacks.
📌 Filters suspicious traffic and blocks intrusion attempts.
📌 Prevents DDoS attacks that can bring your site down.
📌 Protects against SQL injections and malicious scripts.
➡️ Recommendation: Use a Web application firewall (WAF) as Cloudflare, Sucuri or Wordfence.
5. Back up your website regularly
💾 In the event of a cyber-attack or breakdown, a backup enables you to quickly restore your site.
📌 Plan automatic backups at least once a week.
📌 Keep several copies on different servers or in the cloud.
📌 Test the restoration regularly to avoid unpleasant surprises.
➡️ Recommended tool : Use solutions such as UpdraftPlus, Jetpack Backup or Acronis.
6. Protect your site against brute-force attacks
🚀 Brute-force attacks aim to guess your credentials by testing thousands of combinations.
📌 Limit the number of connection attempts with a plugin like Limit Login Attempts Reloaded.
📌 Hide login URL (default /wp-admin for WordPress).
📌 Use reCAPTCHA to block bots.
➡️ Tip: Change your administrator password regularly.
7. Set up safety monitoring and surveillance systems
🔎 Proactive monitoring detects threats before they cause damage.
📌 Install a tool for safety monitoring as Sucuri or iThemes Security.
📌 Activate real-time alerts to be alerted in the event of a hacking attempt.
📌 Regularly check the access and activity logs on your site.
➡️ Conseil: Make a security audit at least once a year.
8. Raise awareness and train your teams in cybersecurity
👨🏫 Safety also requires vigilance on the part of your employees.
📌 Organize training on best practices in cybersecurity.
📌 Set up strict rules for the use of access and sensitive data.
📌 Raise awareness of social engineering and phishing attempts.
➡️ Conseil: Regularly test your teams' reaction to simulated attacks.
