Stop Attacks Before They Hit
Layer 7 protection against OWASP Top 10 attacks, malicious bots, and zero-day exploits. Always-on, sub-millisecond latency, no code changes required.
What WAF Blocks
Real attacks that hit web applications every day. We stop them at the edge.
SQL Injection
Block database attacks that try to steal or manipulate data
Cross-Site Scripting (XSS)
Stop scripts that try to hijack user sessions or deface pages
Cross-Site Request Forgery
Prevent unauthorized actions on behalf of logged-in users
Remote File Inclusion
Block attempts to execute malicious code on your server
Bad Bots & Scrapers
Stop credential stuffing, content scraping, and automated attacks
Brute Force Attacks
Protect login pages from password guessing attempts
What's Included
Everything you need to protect your web application.
OWASP Core Ruleset
Protection against the OWASP Top 10 vulnerabilities—the most critical web application security risks.
Custom Rules
Application-specific rules for your environment. Block requests that match patterns unique to your app.
Bot Management
Block bad bots while allowing legitimate crawlers like Google and Bing. Challenge suspicious traffic.
Rate Limiting
Prevent API abuse and brute force attacks without blocking legitimate traffic during peak loads.
IP Reputation
Automatically block traffic from known malicious IP addresses. Updated continuously.
Real-Time Dashboard
See threats as they happen. Understand what's being blocked and why.
SSL/TLS Termination
Inspect encrypted traffic at the edge. Attacks hiding in HTTPS get caught.
Logging & Reporting
Full audit trail of blocked requests. Export logs for compliance requirements.
Protection at the Edge
Request Arrives
User or attacker sends HTTP request to your domain
WAF Inspection
Request analyzed against rulesets at the edge
Decision
Block, challenge, or allow based on threat level
Clean Traffic
Only legitimate requests reach your server

Who Needs WAF
E-Commerce Stores
Protect customer payment data and account information. Meet PCI DSS requirements for web application security.
SaaS Applications
Secure user-facing APIs and web interfaces. Protect multi-tenant data from cross-tenant attacks.
WordPress & Magento
Stop the automated attacks that constantly probe CMS installations. Block plugin vulnerability exploits.
Any Web Application
If it's accessible over HTTP/HTTPS and handles user data, it needs WAF protection.

Common Questions
Will WAF slow down my site?
No. Our WAF adds sub-millisecond latency—literally faster than a blink. It's deployed at the edge, so traffic is inspected before it even reaches your server. Most customers see no measurable performance impact.
Do I need WAF if I already have SSL?
Yes. SSL encrypts traffic in transit, but it doesn't inspect or block malicious requests. SQL injection, XSS, and other attacks work fine over HTTPS. WAF inspects the content of requests, not just the encryption.
Can WAF block specific countries?
Yes. Geographic blocking is available. Block entire countries, or block all except specific countries. Useful if you only serve certain markets.
What's the difference between WAF and a regular firewall?
Traditional firewalls work at the network level (IP addresses and ports). WAF works at the application level (HTTP requests). A network firewall might allow traffic to port 443, but WAF inspects what's in that traffic and blocks malicious requests.
Does WAF protect against DDoS?
WAF provides application-layer (L7) DDoS protection—stopping HTTP floods and slowloris attacks. For volumetric attacks (L3/L4), you need our dedicated DDoS protection service. Many customers use both.
How quickly are new threats added?
OWASP rules update regularly. For zero-day threats, we can push emergency rules within hours. Our security team monitors emerging threats and updates rulesets proactively.
