Hostinger Firewall Features 2026: How Hostinger Protects Your Website
Hostinger includes a Web Application Firewall (ModSecurity), brute-force protection, malware scanning, and IP-level blocking on all hosting plans. These work automatically with no setup required. Higher plans add enhanced security scanning and faster malware removal response times.
Web Application Firewall (WAF)
Hostinger's Web Application Firewall is powered by ModSecurity — the industry-standard open-source WAF used by millions of web servers globally. ModSecurity inspects HTTP traffic in real time and blocks requests that match known attack signatures including SQL injection, cross-site scripting (XSS), remote code execution, and directory traversal attacks.
The WAF is active by default on all shared hosting and cloud plans. No configuration is required — Hostinger maintains and updates the rule sets automatically to protect against new vulnerabilities.
Brute-Force Login Protection
Hostinger's infrastructure blocks repeated failed login attempts automatically. After a configurable number of failures, the source IP is temporarily blocked. This protects WordPress admin panels, FTP accounts, and SSH access from automated credential-stuffing attacks.
For WordPress sites, Hostinger's WordPress-optimized hosting includes additional brute-force protection at the application layer. Pair this with a strong password and two-factor authentication for maximum protection.
Malware Scanning and Removal
Hostinger performs periodic malware scanning on hosted files. If malware is detected, you receive an email notification and the infected files are identified in hPanel's security section. Some plans include automatic malware removal; others provide detection and require manual action or support-assisted cleanup.
For proactive malware prevention: keep WordPress, themes, and plugins updated, use strong passwords, and consider adding Cloudflare's security features as an additional layer. The most common malware vectors are outdated plugins and compromised admin credentials.
IP Blocking and Rate Limiting
Hostinger's hPanel includes IP blocking tools that let you manually block specific IP addresses or ranges from accessing your website. This is useful for stopping known malicious actors, blocking scrapers, or restricting access from specific geographic regions.
Rate limiting is handled at the network level by Hostinger's infrastructure team. If your site experiences unusual traffic spikes, Hostinger support can apply custom rate limiting to prevent resource exhaustion while you investigate the source.
SSL/TLS Security Hardening
Hostinger's servers are configured with modern TLS settings: TLS 1.2 and 1.3 supported, outdated protocols (SSL 3.0, TLS 1.0, TLS 1.1) disabled by default. This ensures your site receives an A or A+ rating on SSL Labs security tests.
HSTS (HTTP Strict Transport Security) can be configured through hPanel or .htaccess for sites that want to enforce HTTPS browser-level even before a redirect is processed. This protects against SSL-stripping attacks on public networks.
Frequently Asked Questions
Does Hostinger include a Web Application Firewall?
Yes. All Hostinger hosting plans include ModSecurity-based WAF protection that automatically blocks SQL injection, XSS, and other common web attack patterns. It works without any configuration and is updated regularly.
Does Hostinger scan for malware automatically?
Yes. Hostinger performs periodic malware scans on hosted files. If malware is detected, you're notified via email with details of the infected files. Some plans include automated cleanup; others provide detection and manual removal guidance.
Can I block a specific IP address on Hostinger?
Yes. Use hPanel's IP blocking feature or add deny rules to your .htaccess file. For Apache: 'Deny from 192.168.1.1' blocks a specific IP. Hostinger's hPanel interface provides a GUI for managing these blocks without editing files.
Is Hostinger's security good enough for a WordPress site?
For most WordPress sites, yes. WAF, brute-force protection, malware scanning, and SSL are included. For higher-security requirements (membership sites, ecommerce), add Cloudflare and a WordPress security plugin like Wordfence or Solid Security for defense in depth.
Does Hostinger have two-factor authentication?
Yes. Hostinger hPanel supports two-factor authentication (2FA) for your Hostinger account. Enable it under Account → Security to protect your hosting control panel from unauthorized access.
