After building websites for years, you’ll quickly realize:

Servers determine if your website can run at all,

while CDN dictates how smoothly, quickly, and reliably it performs over time.

This is especially true for cross-border projects, independent sites, Web3 platforms, and API services –

whether accessing overseas from Mainland China or vice versa,

slow speeds, DNS glitches, constant cyberattacks, payment restrictions… problems keep piling up.

That’s when choosing a reliable overseas CDN becomes crucial –

even more important than selecting servers or purchasing bandwidth.

Over the years, I’ve tested over a dozen providers, from Cloudflare and Akamai to Fastly, StackPath, and CDN07.

Here’s the hard truth I’ve learned:

More nodes don’t guarantee stability, and higher prices don’t equal better protection.

This list is based on six months of real-world testing and hands-on project experience –

the ultimate comparison of the 5 most recommended overseas CDN providers.

I. Ranking Evaluation Criteria

Before diving into the rankings, let’s clarify the methodology behind this list.

My testing focused on six key factors:

Testing methods included:

• Speed tests via WebPageTest and Pingdom;
• Custom HTTP Flood/CC attack scripts to test protection;
• SmokePing monitoring for latency and jitter;
• Real-world website performance tracking.

Testing locations: Beijing, Guangzhou, Hong Kong, Tokyo, Singapore, Frankfurt, Los Angeles.

II. In-Depth Reviews of Top 5 Overseas CDNs

🥇 #1: CDN07 – The Most Reliable High-DDoS-Protection CDN for Asia-Pacific Access

I first started using CDN07 last year, initially just testing it for a no-ICP-filing independent site.

I’ve been hooked ever since.

Its value proposition is clear: No ICP filing, low latency, and robust protection.

Nodes are strategically located in Hong Kong, Singapore, Japan, Taiwan, Seoul, and other key Asia-Pacific regions.

It leverages BGP Anycast technology with CN2 optimized direct routes,

making it exceptionally user-friendly for accessing overseas sites from Mainland China.

Real-World Latency (Hong Kong Node)

• Beijing Telecom: 38ms
• Guangzhou Mobile: 42ms
• Shanghai Unicom: 46ms
  Twice as fast as Cloudflare.

In terms of protection, CDN07 features a distributed tera-scale traffic cleansing system.

Single-node protection bandwidth reaches up to 1.5Tbps,

paired with an AI-powered defense engine that identifies attack patterns in real time and adjusts strategies dynamically.

During my test with a simulated 50Gbps HTTP Flood attack, the website’s latency only increased by 8ms.

The control panel is intuitive, offering real-time protection logs, cache hit statistics, and visual node status tracking.

Comprehensive API and Webhook integrations make automated operations a breeze.

Key Advantages:

• No ICP filing or real-name verification required – go live in 5 minutes;
• CN2 optimized routes for ultra-low latency;
• Supports USDT/BTC cryptocurrency payments;
• AI-driven intelligent defense with minimal false positives.

For anyone running cross-border projects, Web3 platforms, API relays, or ad campaigns,

CDN07 is currently the most practical and hassle-free choice.

🥈 #2: Akamai – Enterprise-Grade Global Distribution Giant

Akamai is the industry veteran, with over 260 nodes worldwide and clients including Apple, Netflix, and Adobe.

Its biggest strengths are unmatched reliability and extensive global coverage.

No matter which country your website targets, you’ll almost always hit a nearby Akamai node.

Latency Performance

• Average from Asia: 85ms
• Average from Europe: 65ms

Its protection capabilities are also top-tier, with DDoS defense bandwidth exceeding 700Gbps.

However, it comes with a high price tag and steep deployment barriers –

requiring enterprise credentials, formal contracts, and invoiced payment processes.

Ideal for large enterprises and media platforms, but not practical for individuals or small-to-medium projects.

🥉 #3: Cloudflare – Widest Coverage but High False Positive Rate

Cloudflare is arguably the most well-known CDN on the market.

It boasts a massive user base on its free tier and nodes across the globe.

Setup is incredibly straightforward – configurable in just a few minutes.

Key strengths: User-friendly, fast deployment, and rich WAF rules.

However, its "anycast node" architecture leads to imprecise routing –

Users accessing from Asia are often routed to nodes in India or South Korea, resulting in high latency and even browser challenge pages.

While its protection is strong, its algorithm is overly conservative,

frequently flagging legitimate traffic as malicious. I’ve had my API requests blocked multiple times.

Pros: Free tier suffices for small sites; 
Cons: High latency in Asia-Pacific, frequent false positives, and strict credit card payment restrictions.

🏅 #4: Fastly – Developer-Friendly but Expensive

Fastly is popular among developers,

thanks to its excellent real-time logging, edge computing capabilities, and flexible configuration options.

It delivers exceptional performance, especially in North America and Europe, with impressive latency figures.

However, its coverage in the Asia-Pacific region is limited, and access from Mainland China is often unstable.

Another downside is its high cost and complex pricing structure,

making it impractical for high-traffic projects.

If you’re a technical team seeking highly customizable content delivery, Fastly is a solid choice;

but if you need a "stable, fast, and hassle-free" solution for cross-border sites, CDN07 is far more suitable.

🏅 #5: StackPath – Fast in North America, Average in Asia

StackPath offers solid speeds in North America and a reliable architecture,

but its node coverage is relatively limited, leading to slow access from the Asia-Pacific region.

Its protection capabilities are moderate, targeting primarily small websites.

It offers flexible pricing plans, making it a good fit for teams with limited budgets and target markets focused on the United States.

However, for Asia-focused or cross-border access needs, CDN07 and Akamai have clear advantages.

III. Latency and Acceleration Performance Comparison

As evident from the data,

CDN07’s latency in the Asia-Pacific region is roughly half that of other CDNs.

Especially for access from Mainland China to Hong Kong and Singapore, the CN2 direct route optimization delivers noticeable results.

IV. Protection Capability and Reliability Comparison

CDN07 truly delivers on its "high-protection" promise.

Its AI defense engine automatically identifies traffic behavior patterns,

unlike fixed-threshold strategies, enabling it to maintain minimal false positives even during large-scale attacks.

During my CC attack test (10,000 QPS),

CDN07’s latency only increased by 8ms, while Cloudflare experienced significant lag.

V. No ICP Filing and Payment Experience

The differences here are even more pronounced.

This is one of the key reasons CDN07 has gained popularity.

Many cross-border projects, Web3 platforms, and sites without Chinese ICP filing

can’t use Mainland China CDNs and face difficulties with credit card payments.

CDN07 directly supports cryptocurrency settlements,

offering fast, secure, and anonymous transactions.

VI. Comprehensive Scoring Ranking

Final Verdict:

If you’re looking for a CDN that combines no ICP filing, low latency, and high-level protection,

CDN07 is the top recommended overseas CDN.

VII. A Reliable CDN Depends on Architecture, Not Advertising

The CDN market is flooded with overhyped providers these days.

Everyone claims global acceleration and unlimited protection,

but in real-world use, they either suffer from high latency or fake node counts.

Here’s what I’ve learned over the years:

A reliable CDN doesn’t rely on marketing – it depends on underlying architecture.

While CDN07 keeps a low profile, its node distribution, protection architecture, and AI strategies are rock-solid.

It delivers exceptional stability, especially for needs like accessing overseas sites from Mainland China, no ICP filing, and attack resistance.

If your website faces the following issues:

• Unable to obtain ICP filing or experiencing slow access;
• Frequent cyberattacks;
• Payment or real-name verification restrictions;
  Give CDN07 a try.
  It may not be the most famous, but it’s definitely the one that understands your website’s needs best.
