Every day, company websites and services face numerous cyber threats: hacking attempts, data theft, bot attacks, and DDoS overloads.

An effective tool to protect against these threats is a WAF, or Web Application Firewall.

Why Do You Need a WAF?

Simply put, a WAF is a filter that stands between your website or web application and the entire internet. It analyzes incoming requests from users (or bots) and allows only safe ones to pass through. If a request appears suspicious—for example, someone tries to insert malicious code instead of a regular login—WAF blocks it before it even reaches your server.

Let’s Compare: Traditional Firewall vs. WAF

🔹 A traditional firewall protects the network as a whole. It monitors IP addresses, ports, and protocols

🔹 A WAF focuses on web applications. It inspects HTTP requests, checks forms, cookies, URLs, and even user behavior

If you imagine a traditional firewall as a security guard at the entrance, then a WAF is also a scanner that inspects every visitor inside.

Why Does a Data Center Need a WAF?

At “PARKOVY” Data Center, we use WAF to:

🔹 Protect internal services: websites, control panels, API access, and cloud platforms

🔹 Enhance resilience to application-level attacks

🔹 Isolate client environments: so that an attack on one site does not affect others

How Does WAF Work in Practice?

Imagine this: your website has a contact form. A malicious actor tries to enter a special code into the name field instead of an actual name to gain access to your database.

If a WAF is active, it will “see” that this is not a regular name but a potential threat and will block the request.

Another example: a bot floods the website with thousands of requests to overload it. The WAF detects the abnormal activity and blocks the traffic.

What Should You Know?

Even if you’re not an IT expert, it’s important to understand:

🔹 A WAF is a digital security guard that works 24/7

🔹 It updates automatically, adapting to new types of attacks

🔹 WAF does not interfere with your site’s operation – on the contrary, it helps prevent disruptions

WAF – A Key Tool for Cloud Cybersecurity

It helps your site operate safely, reliably, and without data loss. If your web applications and site are the core of your business, then you need a WAF.

And here at “PARKOVY” Data Center, we’ll make sure it’s properly integrated into your cloud environment and running efficiently.
