Common Questions
Will WAF slow down my site?+
No. Our WAF adds sub-millisecond latency. It's deployed at the edge, so traffic is inspected before it reaches your server.
Do I need WAF if I already have SSL?+
Yes. SSL encrypts traffic in transit but doesn't block malicious requests. WAF inspects the content of requests.
Can WAF block specific countries?+
Yes. Geographic blocking is available. Block entire countries or allow only specific ones.
What's the difference between WAF and a regular firewall?+
Traditional firewalls work at the network level (IP/ports). WAF works at the application level (HTTP requests).
Does WAF protect against DDoS?+
WAF provides L7 DDoS protection. For volumetric attacks (L3/L4), you need our dedicated DDoS protection service.
How quickly are new threats added?+
OWASP rules update regularly. For zero-day threats, we can push emergency rules within hours.
