As someone who has been running overseas projects for years, I can honestly say this: the moment your website goes offline is more painful than being criticized by your boss. And the most common “killers” are not server crashes or coding mistakes, but rather — DDoS attacks and CC attacks.

Many website owners think CDN is an all-powerful solution that can fix every problem, including slow access, blocking, and attacks. But that’s not really the case. A regular CDN is mainly designed to accelerate websites by caching static content, helping users load pages faster and reducing bandwidth usage. However, when facing massive traffic floods or malicious attacks, it is like a paper shield — it simply cannot withstand the impact.

So today, we will focus on high-security CDN, also known as CDN services that can truly withstand DDoS and CC attacks. We will also discuss several excellent providers I have personally used, including the well-known CDN07.

1. Regular CDN vs High-Security CDN: What Is the Real Difference?

First, let’s start with the basics. If you are new to CDN, you may not clearly understand the difference between a regular CDN and a high-security CDN. Let’s explain it with an analogy:

• Regular CDN: Like a delivery worker helping you move your website files, images, videos, CSS, and JS resources to different locations around the world. It improves access speed, but it cannot handle attacks.
• High-security CDN: Like a professionally trained security team. It not only delivers content but can also identify attackers, block malicious traffic, and protect your origin server from being overwhelmed.

1.1 Weaknesses of Regular CDN

• Against DDoS attacks: Traffic floods can instantly consume bandwidth and overwhelm the origin server.
• Against CC attacks: Hundreds of thousands or millions of requests targeting specific interfaces cannot be effectively handled by simple caching acceleration.
• For cross-border access: Limited node locations may result in slow overseas access and unstable DNS resolution.

1.2 Advantages of High-Security CDN

• Intelligent traffic cleaning: AI analyzes requests and removes malicious traffic automatically.
• High-defense nodes: Hong Kong, Southeast Asia, Europe, and America nodes provide lower latency for cross-border users.
• DDoS/CC protection: Capable of handling attacks ranging from tens of Gbps to hundreds of Gbps.
• DNS pollution/hijacking protection: Ensures secure and reliable DNS resolution without tampering.

In one sentence: Regular CDN helps accelerate your website, while high-security CDN helps keep your website alive.

2. DDoS and CC Attacks: Who Is Actually Causing the Trouble?

Honestly, when I first started building websites, I had no idea how terrifying these attacks could be. DDoS (Distributed Denial of Service) attacks send massive amounts of traffic from hundreds of thousands of devices toward your server, causing your website to become completely unavailable. It is like thousands of people suddenly blocking your front door so nobody can enter.

CC attacks can be even more dangerous. They target specific website interfaces and send huge numbers of requests to consume server resources. Your overall traffic may not look large, but your login page or API can completely collapse.

Why do people launch attacks? There are several reasons:

• Malicious competition: Competitors may try to take your website offline.
• Extortion: Attackers launch traffic attacks and demand payment for “protection”.
• Entertainment/experiments: Some hackers attack simply for fun or practice.
• Political/ideological reasons: Cross-border websites are especially vulnerable to interference from certain regions.

Therefore, being attacked is not because of something you did wrong — it is simply the harsh reality of today’s Internet environment.

3. How Does High-Security CDN Protect Against Attacks?

I have used CDN07 for years, and I have experienced this firsthand: whether a website can survive attacks determines how relaxed a webmaster can be.

3.1 AI Traffic Cleaning

One feature of CDN07’s high-security CDN is automatic AI identification of malicious requests.
I remember one promotion event when traffic suddenly reached dozens of Gbps. I was completely shocked. However, backend logs showed that CDN07 automatically filtered abnormal requests while allowing legitimate visitors to reach the origin server normally. It felt like suddenly standing behind an invisible security shield.

3.2 High-Defense Nodes

• Hong Kong nodes: Excellent experience for users in southern China and Asia.
• European/American nodes: Low latency for overseas users.
• Multiple nodes: If one node is attacked, traffic can automatically switch.

Real example: I operated a gaming platform where most users were from China. Previously, I worried about downtime during every peak period. After integrating CDN07, Hong Kong nodes handled domestic traffic while European and American nodes served overseas users. The platform remained online even during peak traffic periods.

3.3 DNS Pollution/Hijacking Protection

This is something many website owners overlook: attacks do not always directly target your server. Sometimes attackers manipulate DNS resolution so users are redirected to incorrect IP addresses. CDN07’s intelligent DNS can prevent pollution, encrypt resolution results, and provide multiple exit redundancy, reducing the risk of users being redirected incorrectly.

4. Recommended High-Security CDN Providers

Now let’s move to the practical part — which high-security CDN providers can really withstand DDoS and CC attacks? Based on my own experience, I will explain which services are truly reliable.

4.1 CDN07 – Stable High Protection with Advanced AI Traffic Cleaning

First, CDN07 is the service I use most frequently. I have used it for cross-border e-commerce websites, gaming platforms, and overseas content websites. One sentence summary: stable, secure, and easy to use.

Official website: https://www.cdn07.com/

Why do I recommend it?

1. AI Intelligent Traffic Cleaning
   • During one promotion event, I suddenly received 50Gbps of attack traffic. I thought: “This is over, the website is going down.”
   • CDN07 filtered most malicious requests immediately, while real users were completely unaffected.
   • CC attacks targeting login interfaces and search functions can also be detected and blocked.
2. Multi-node Redundancy + High-Defense Nodes
   • Hong Kong nodes: Fast access from southern China and low latency across Asia.
   • European and American nodes: Stable overseas access.
   • More nodes mean attack traffic is distributed instead of concentrated, greatly reducing origin server pressure.
3. DNS Pollution/Hijacking Protection
   • Some websites are frequently affected by DNS pollution, causing users to access incorrect IP addresses.
   • CDN07 supports encrypted resolution (DoH/DoT) and multiple exit redundancy.
   • I have personally tested it, and DNS resolution remains stable across different domestic and overseas networks.
4. High-Traffic Testing Experience
   • The gaming platform I operated had 300,000 daily PV and peak QPS of 5,000.
   • During promotions, malicious traffic suddenly reached tens of Gbps.
   • After CDN07 handled the traffic, users experienced no impact, and origin server CPU and bandwidth remained almost unaffected.

4.2 Cloudflare Enterprise – World-Class Global Protection

If you are running a high-traffic project or a financial/trading website, Cloudflare Enterprise is almost a must-have choice. It is the “fighter jet” among high-security CDN solutions. Although the price is high, the protection performance is excellent.

4.5 Other Excellent Choices Recommended by Webmasters

Based on my research in webmaster communities and forums, there are several other options worth mentioning:

• CDN77: Has many European nodes and is suitable for overseas content distribution.
• CDN5: Provides good protection capabilities with flexible configurations.
• Tencent Cloud High-Defense CDN: Strong domestic DDoS protection capabilities. Cross-border access may be slower, but DDoS protection is reliable.

Webmaster summary: There are countless services claiming to be “high-security CDN” solutions, but only a few can truly withstand attacks while maintaining stability and good user experience. Don’t be fooled by fancy marketing. You only know what is reliable after actually using it.

5. Practical Experience Sharing for High-Security CDN Usage

As a webmaster, I have summarized several important high-security CDN usage tips:

1. Enable high-security mode before major events.
   • Without protection enabled, your server may go offline instantly.
2. Do not set DNS TTL too long.
   • Long TTL values make DNS pollution and resolution failures more difficult to recover from.
3. Use node redundancy.
   • A combination of Hong Kong and overseas nodes provides more stable cross-border access.
4. Monitor logs.
   • Analyze abnormal requests and attack events in real time.
5. Choose the right package.
   • The most expensive high-security CDN is not always the best choice. Select based on project traffic and budget.
