Here are 5 proven practices to harden your PHP 8.4 applications:

1. Input Validation and Sanitization: Always validate and sanitize user inputs. Use functions like htmlspecialchars(), filter_var(), and parameterized queries to prevent XSS and SQL injection attacks.
2. Regular Security Audits and Penetration Testing: Conduct regular security audits and penetration testing to identify vulnerabilities before attackers do. Expert Developers provides comprehensive security audit services. Schedule a consultation today!
3. Utilize a Content Security Policy (CSP): Implement a robust CSP to control the resources a browser is allowed to load, mitigating the risk of XSS attacks.
4. Keep PHP and Dependencies Updated: Regularly update PHP and all dependencies to patch known vulnerabilities. At Expert Developers, we have automated patching and update processes. Let us handle your updates.
5. Implement Two-Factor Authentication (2FA): Enable 2FA for all user accounts to add an extra layer of security against credential compromise.

We recently helped a client, a leading e-commerce platform, reduce their attack surface by 70% through implementing these practices and other custom security measures.
