What is Layer 7?
Layer 7 attacks target the application layer of your infrastructure: HTTP floods, malicious bots, aggressive scraping, slowloris and targeted API attacks. Unlike volumetric L3/L4 attacks, they are harder to detect as they mimic legitimate traffic.

Frequently asked questions
Does the challenge slow down my site?
No. The JavaScript challenge runs in the background and is completely transparent to human visitors. Only bots and malicious scripts are blocked or shown a waiting page.
Does it work with my current hosting provider?
Yes. Layer 7 protection works with any hosting provider. It sits upstream via a DNS redirect or reverse proxy, without touching your existing server.
What is the difference with L3/L4 Anti-DDoS?
L3/L4 protection filters volumetric network attacks (UDP floods, SYN floods). Layer 7 targets application attacks (HTTP floods, bots, API abuse). Both are complementary and can be combined.
What does this service cost?
Pricing depends on your traffic volume and service configuration. Contact our team for a custom quote.
