Recently, there are always people in the group asked, there is no high defense CDN can be free to try? These days, no one wants to spend money to buy a “vase” decoration, especially network security this thing, do not test a hand simply do not know whether to rely on.
I have been in this line of climbing and rolling less than seven or eight years, have seen too many people blindly believe in the vendor propaganda, the results of a line was DDoS directly through, crying too late. So my advice is one sentence:Try before you buy, and don't be upset about that little test time.。
But the question arises, which high defense CDN really willing to let you whoring test? Some talk about free, but hidden routes: either the node is pathetic, or limit the flow limit to the heart, and even sneak you into the “castrated version” of the protection. Today I will combine the experience of real testing, pickpocket 5 really support the free experience of the service provider, and by the way, teach you how to avoid those pits.
Cold water first: free trial ≠ unlimited whoringThe cost of a high defense is very high, but the cost of a high defense is very high. However, any serious high defense, the cost is there. Servers, bandwidth, protection hardware, which is not burning money goods? So meet the claim “permanent free”, I advise you to direct detour - either the gimmick of pulling customers, or protection ability is about the same as the paper mache.
The real value of the trial is to let you verify in a real environment: how effective is the acceleration? Can the CC attack be carried? Here are a few I have personally tested or have a team of real test feedback, the advantages and disadvantages will be clear, never ambiguous.
First: CDN5 - newbie-friendly and flexible enough for protection strategies
CDN5's free trial is considered to be one of the more conscientious in the industry. Directly after signing up to send a 7-day trial, including 5TB of traffic and basic DDoS protection (up to 20Gbps). Although the peak protection is not top-notch, but for small and medium-sized sites is completely enough.
I tested it and found their CC protection to be a bit of a thing. Default rules can block most of the garbage requests, and support for customized frequency thresholds. For example, you can set a single IP request over 50 times per second directly popping the verification code, this point is very practical to prevent crawlers and CC attacks.
Configuration example (backend rule setting):
The downside is that the overseas nodes occasionally jerk around, but the domestic access speeds are stable. Worth a try if your main users are domestic.
Second: CDN07 - exclusive for techies, APIs to play around with
CDN07's free package is hidden deeper and requires a work order application (just say you want to test the high defense effect). They give 14 days trial, unlimited traffic but limited QPS (requests per second), the default gives 3000QPS, enough for you to simulate a wave of stress test.
The biggest highlight is the perfect API support. All configurations can be adjusted through the interface, suitable for automated operation and maintenance. For example, dynamic switching of protection modes with scripts: monitor mode is normally on, and attacks are detected and automatically switched to strict mode.
I wrote a sample simple script (Python + their API):
Note: His background interface is a bit anti-human, but the documentation is written in extremely fine. Suitable for technical teams to toss, white caution.
Third: 08Host - Overseas Party Exclusive, Global Nodes Optional
08Host focuses on overseas acceleration, free trial for 30 days (requires enterprise mailbox registration). Protection value to give generous - 100Gbps + DDoS protection, but also with WAF function. I took the test station brush a wave of simulated attacks, TCP flood and HTTP Flood basically all blocked.
Node coverage is really wide, Europe and the United States, Southeast Asia, the Middle East, but the domestic access latency is slightly high (200ms +). Suitable for overseas business or projects with user groups in foreign countries.
There's a hidden benefit: custom certificates and HTTP/3 protocols are supported during the trial period. Configuration segment reference:
One complaint: customer service response is slow and sometimes poor. But the technical documentation is complete and the experience is good if you can handle it yourself.
House 4: SharkTech - the king of resistance, for the unlucky ones who are targeted
If you're already scared of being hit, SharkTech's free trial is worth applying for. They specialize in “Unlimited Protection”, and in real-world tests, they have survived 500G+ mixed attacks (UDP+ICMP+HTTP Flood).
The trial period of 14 days, you need to provide the domain name and business type (will be manually audited). The protection strategy is aggressive to perverse - suspected attack traffic directly null route, false positive may be a little high, but really - rather than wrong kill not to let go.
Real-world advice: whitelist your core IPs first, then turn on strict mode. Otherwise you may shut yourself out too ......
Moderate in terms of speed, but top-notch in terms of stability. Suitable for high-risk industries like finance and gaming.
Fifth: ShieldNode - niche but accurate, CC protection is unique!
This last one is a bit cooler, but the CC protection is really fine. Free trial 10 days, unlimited traffic but limited to 10 domain names.
The strongest is the human-machine verification system: it supports JS challenge, cookie verification and even sliding CAPTCHA. When I simulated a CC attack, the 95% swipe request was blocked by CAPTCHA and the business interface was almost senseless.
Backend configuration example:
The downside is the small number of nodes and fluctuating latency. But if you're getting head balding from CC attacks, try it and you might be pleasantly surprised.
The right posture for a free trial: don't be stupid and go straight to the production environment
Even if you give it a trial, don't wave it. I've seen people cut through production traffic right off the bat and end up with a straight 515 error when they didn't get the configuration right. The reliable thing to do is:
1. Run first with a test domainThe following are some of the things that you can do: get a secondary domain name (e.g. test.your-site.com), resolve to the CNAME of the CDN vendor, and simulate the attack with a pressure test tool to see if the protection is in effect.
2. Keeping an eye on the log: Pay particular attention to false positives. Real users blocked? Adjust the rules quickly. Recommended to use ELK or Splunk real-time monitoring.
3. Measuring speed without forgetting geographical differencesThe key point is to measure the latency of three networks if there are a lot of domestic users, and to measure overseas nodes for overseas business. Recommended tools: WebPageTest or GTmetrix.
4. Looking at after-sales response: Intentionally raise a work order during the trial period to see how quickly and professionally customer service responds. Vendors who drop the ball at critical moments, directly pass.
Finally, to tell the truth: there is no universal solution for high defense CDN. Different business scenarios have completely different needs - games to low latency, e-commerce is afraid of CC attacks, official websites value stability. The biggest value of the free trial is to help you eliminate the wrong options.
Don't just look at the peak protection numbers either. Some vendors claim 1Tbps protection, the actual reliance on the upstream cleaning plant, traffic around a circle delay blow through. The real reliable, is the local cleaning + distributed nodes + flexible rules combination.
In conclusion.It's okay to whore for nothing, but do it with a brain.The first thing you need to do is to test the speed, protection, and compatibility of your computer. Measure the speed, measure the protection, measure the compatibility, a set of processes to complete, the right to stay, not the right to save money. After all, these days, even the CDN have to “defense teammates” - do not be false labeling parameters fooled, the actual test is the hard truth.
