Cloudflare is much more than DDoS protection—it is a comprehensive security and performance platform that includes DNS, L3/L4 and L7 DDoS protection, a Web Application Firewall, and advanced bot traffic management. Deployment is fast and minimally invasive, and in most cases the environment moves directly from testing to production—sometimes within as little as 24 hours. Clients are most often positively surprised by the immediate effectiveness of security rules, full traffic visibility, and a real improvement in application performance. Cloudflare’s key advantage is its massive, global infrastructure (over 405 Tbps), which enables effective mitigation of even record-breaking, multi-vector DDoS attacks while ensuring high service availability, including in highly regulated environments.

Over the years, Cloudflare has become one of the key elements of security infrastructure for companies operating online. Although many people associate it mainly with DDoS protection, in practice its capabilities go far beyond that. The platform integrates DNS, WAF, automated traffic management, and SASE/ZTNA services, creating a cohesive ecosystem that sits at the intersection of performance and security.

This article describes which components we most often deploy for our clients, what the implementation process looks like step by step, and what tends to surprise users the most once the solution goes live.

Which Cloudflare components do we most often deploy for our clients?

In most cases, Cloudflare deployments start with two elements that can now be considered standard: DNS, DDoS protection, and WAF.

1. Cloudflare DNS

Today, it is difficult to find a company that uses Cloudflare but does not rely on it for DNS. There are two main reasons: performance and resilience to attacks. Cloudflare operates one of the fastest DNS services in the world, resulting in extremely fast record propagation. At the same time, the built-in architecture provides high resistance to volumetric attacks.

Reports published by leading Anti-DDoS solution vendors show that DNS Amplification attacks are increasingly appearing among the top five most common attack types. These attacks abuse DNS servers as intermediaries in large-scale campaigns. Cloudflare effectively protects DNS services against such attack attempts.

2. DDoS protection – Layers 3/4 and 7

The second most frequently deployed component is DDoS protection. Cloudflare provides protection both at the network level (L3/L4) and the application level (L7).

In simple terms:

• L3/L4 protection prevents infrastructure overload through increased traffic caused by classic volumetric attacks such as SYN Flood or UDP Flood.

• L7 protection focuses on the application layer, protecting web applications against volumetric attacks that are difficult to detect due to traffic encryption using HTTPS.

3. Web Application Firewall

We also very often deploy WAF (Web Application Firewall) systems—solutions that filter and monitor HTTP traffic to protect web applications from attacks.

It is worth noting that as much as 40% of all internet traffic today is automated. Distinguishing “good” bots (such as search engine crawlers) from malicious traffic requires advanced behavioral analysis and reputation-based mechanisms.

These capabilities are provided by Cloudflare Bot Management, a module integrated with the WAF that allows real-time traffic classification, blocking of attacking bots, and infrastructure protection without negatively impacting user experience.

What does a typical Cloudflare deployment look like?

From a technical perspective, deploying Cloudflare is simpler compared to on-premises WAFs and Anti-DDoS systems, but the preparation and analysis phase is crucial. Everything starts with a conversation with the client to define priorities.

The first stage involves analyzing the environment architecture and selecting the appropriate components.

The second stage is preparing a test environment. On the client side, this usually comes down to creating a free Cloudflare account and confirming readiness for testing. All other activities are handled by our team.

The next step is launching a proof-of-concept trial license. This allows full testing of Cloudflare’s features without impacting the production environment.

During testing, we switch a test domain to Cloudflare servers and demonstrate how individual modules work—WAF, DDoS protection, traffic rules, caching, bot analysis, and API protection. Traffic is redirected at the DNS level to Cloudflare’s infrastructure.

In about 95% of cases, the test environment then becomes the production environment. There is no need to repeat the configuration—activating the license and adding additional domains is enough.

This is one of Cloudflare’s biggest advantages: deployment is fast, minimally invasive, and practically ready for use immediately after testing. In favorable conditions—when the client is ready—basic protection can be launched within as little as 24 hours.

What are the most common false assumptions made by clients?

One frequent misconception before deployment is concern about using a cloud-based WAF. This is especially common in organizations from the financial sector, which must comply with strict regulations such as NIS2, DORA, or internal security policies.

The concern stems from the fact that for a WAF to function effectively, it must decrypt SSL traffic, which implies access to HTTPS communication content. Naturally, the question arises: “Will this data leave our infrastructure?”

Cloudflare has addressed this challenge. The platform allows traffic processing to be restricted exclusively to data centers located within the European Union, ensuring compliance with personal data protection regulations.

What usually positively surprises clients during deployment?

The biggest surprise after deployment is usually speed. Clients often expect long configuration change cycles, while in reality new security rules in Cloudflare become active within seconds of implementation.

Another surprise is the analytics module. Cloudflare not only filters traffic but also provides full visibility into incoming traffic to applications. Clients often admit that only after deployment did they gain real insight into what is happening in their applications—where traffic comes from, which protocols dominate, and which parts of the application are most frequently attacked.

A third immediate effect is performance improvement. After deploying Cloudflare, application servers are noticeably less loaded—much of the unwanted traffic (bots, scanners, unauthorized requests) is stopped at Cloudflare’s data center level. This is directly reflected in performance metrics on the origin servers.

What sets Cloudflare apart from the competition?

From a technical standpoint, it is difficult to point to another solution that matches Cloudflare in terms of infrastructure scale and effectiveness against volumetric attacks.

Cloudflare’s global infrastructure currently exceeds 405 Tbps of inbound capacity—the amount of traffic the platform can accept and process directly at the edge. For comparison, the closest competitors operate in the range of 15–20 Tbps. The difference in scale is enormous.

This advantage translates directly into effectiveness. Cloudflare is uniquely capable of handling hyper-volumetric, complex, distributed attacks that use multiple ports and large packets generated from many directions simultaneously.

Such attacks are particularly problematic because they cause not only link saturation but also excessive resource consumption on the victim’s infrastructure. Cloudflare addresses this through its global network, which automatically disperses traffic across hundreds of data centers before it reaches client servers. As a result, even attacks reaching tens of terabits per second are effectively mitigated and blocked.

Thanks to its distributed infrastructure, Cloudflare is one of the few providers capable of guaranteeing service availability even in the face of record-breaking attacks. If you want to see how to effectively protect your organization against DDoS attacks, contact us.
