Protect Your Website Against Attacks
with WAF Service

A WAF is an application-layer firewall that protects your web applications against SQL injection, XSS (Cross-Site Scripting), CSRF and other OWASP Top 10 attacks. Unlike normal firewalls, it deeply analyzes HTTP/HTTPS traffic and blocks malicious requests before they reach your server.

A regular (network) firewall filters by IP address and port. A WAF works at the application layer (Layer 7) and analyzes the content of HTTP requests. Only a WAF can detect and block web-based attacks like SQL injection and XSS. The two are different security layers that complement each other.

Our WAF service protects against SQL Injection, Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), File Inclusion, malicious bot traffic, brute force attacks, DDoS (Layer 7) and all web security threats under OWASP Top 10.

No. Our WAF infrastructure runs on high-performance servers and performs traffic analysis in milliseconds. Your regular visitors do not experience any latency. You may even observe a performance improvement, as malicious traffic is filtered out and server load is reduced.

The bot verification system separates traffic coming to your site into real users and bots. While allowing legitimate search engine bots like Google and Bing, it detects and blocks malicious bots (scrapers, spam bots, credential stuffing). As a result, your site stays safe and your SEO performance is not affected.

You can manage our WAF service via API — adding/removing rules, fetching traffic reports, managing IP allow/deny lists and more. By integrating with your existing CI/CD pipeline or security tools, you can automate your security management.

Yes, security rules are continuously updated. Rule sets are automatically updated against newly discovered security vulnerabilities (including zero-days) and attack methods. Your protection stays up to date without any action on your side.

Yes, our WAF service is compatible with any hosting provider or server. All you need to do is point your DNS settings to our WAF infrastructure. You don't need to be a Kolan customer; you can also get the WAF service for servers outside Kolan.

Our WAF rules are optimized to minimize the false-positive rate. You can also define custom rules to add specific IP addresses or request patterns to an allow list. When needed, our technical team provides support on rule optimization.

Your WAF service is activated quickly after order approval. All you need to do is point your DNS settings to our WAF infrastructure. Our technical team guides you through the setup and supports you until everything is verified to work correctly.
