A denial-of-service attack floods a server with requests until it cannot serve your real visitors. At Hyyat Host the CSF firewall on our servers provides tools to limit connections and block abusive addresses automatically. This page explains the attack types, the signs, the honest limits of each protection, and what to do if your site is a repeated target.
A denial-of-service (DoS) attack aims to take your service offline by flooding the server with more requests or connections than it can handle. Some attacks need just one machine, like Slowloris, which opens many connections and keeps them hanging until the web server is full.
A DDoS attack is distributed, coming from thousands of machines at once, often botnets. Attacks are not limited to websites over HTTP; they can target other services such as SSH, FTP and email.
In short: A DoS attack floods the server from one or a few sources, while DDoS comes from thousands of machines. We limit the first on Hyyat Host servers with CSF tools; very large distributed attacks are stopped at network level or by CDN services.
Understanding the stages of an attack helps you stop it early, before it reaches your data and visitors.
No single protection stops every attack, so we rely on tools that work together, and we are honest about their limits:
These tools run on our hosting servers and on servers we protect under the server management service.
Server protection is half the way; the other half is in your hands. These simple steps make a big difference.
We manage server protection fully: the CSF firewall, LFD blocking, ImunifyAV scanning and mail filtering. You keep your site updated and your passwords safe.
Shared hosting →The server is fully yours, and its protection is your responsibility unless you subscribe to server management, where we install, tune and monitor the protection tools.

A DoS attack comes from one or a few machines, while DDoS is distributed, coming from thousands of machines at once.
Yes, the CSF firewall on our servers provides per-address connection limits and automatic blocking of abusive addresses, which stops small and medium attacks.
No server-level protection can stop huge distributed attacks on its own; those are stopped at network level or by CDN services before reaching the server.
An attack that opens many connections to the web server and sends data very slowly until the server is full; one machine is enough.
Signs include sudden slowness, 503 or 508 errors, high load and many connections from a few addresses. Contact support to analyse the logs.
Large or targeted sites benefit from a VPS or dedicated server with independent resources, plus server management to tune protection to their needs.
Network attacks flood the connection itself with huge volume, while application attacks send normal-looking requests to heavy pages. DDoS protection for a server against large attacks needs network protection or a CDN.
It may cause temporary slowness because resources are shared, which is why DoS protection blocks the source quickly to limit the impact on other sites.
With server management we install, tune and monitor the protection tools, so you can focus on your business.
