Attack Protection : Cloudflare automatically identifies and blocks threats before they can reach the server hosting your website. This means it is a strong ally Protect Your Website against DDoS attacks, hacking attempts, and other online threats.
Content caching : Cloudflare leverages the power of the
CDN of numerous geographically distributed servers, in which it caches the content that is distributed by the server closest to the user’s request, thus reducing latency times.
DNS : Cloudflare DNS is a DNS service that aims to provide faster response times, advanced redundancy, and security with built-in DDoS mitigation and DNSSEC.
If Cloudflare is enabled, it will test the legitimacy of incoming users by choosing a managed challenge based on the requests, which may include:
An interactive challenge , inviting the user to click a button
A non-interactive challenge page ( JS Challenge , the most popular and recommended by Cloudflare itself). With a JS challenge, Cloudflare does not require any interaction from the visitor, but rather a JavaScript processing by their browser. In this case, the user will simply have to wait until the website accepts their request (on average less than five seconds).
Cloudflare chooses to display a challenge when:
The visitor’s IP address exhibited suspicious behavior.
The user’s IP is among those from a specific country that rich people number data have been blacklisted by the website owner.
The visitor’s actions triggered a firewall rule enabled by the website owner.
To disable or increase DDoS protection, you need to apply the desired security level.
What is Cloudflare “Security Level”?
The “ Security Level ” option determines the security level of your website and, based on the parameter you set, Cloudflare decides whether to present a challenge using the reputation of the visitor’s IP address.
Cloudflare is a CDN (Content Delivery Network) that boasts hundreds of data centers located in more than 100 countries and approximately 25 million Internet properties, managing an average of 35 million HTTP requests per second. and protect websites from illicit intrusions, thus ensuring both greater protection from external threats and faster loading times especially for those portals that daily receive a significant amount of traffic. Cloudflare, therefore, leverages two characteristics: speed and security .
Safety
Acting as a firewall, Cloudflare filters traffic by blocking a large part of the actions of malicious people, in particular it protects against. DDoS attacks that aim to overload a server to the point of interrupting its activity. The network also filters crawlers and bots : if unreliable they are immediately blocked, while those. Previously approved (such as those of Google that work to process and index pages) pass.
Cloudflare offers free and premium options
The latter solutions offer even more structured levels of protection than the former. Defending websites from “injections” of malicious code into the database (for example, SQL injection ).
In late August 2023, Cloudflare announced that it had mitigated the largest. DDoS attack in the history of the web, detecting a peak of more than 201 million requests per second.
Speed
Technically, it is a caching reverse proxy : Cloudflare’s infrastructure what is social media sentiment analysis stands. Between clients , users who make requests from browsers, and servers , infrastructures where websites are hosted. Making content loading faster because it is pre-saved ( caching ) in architectures located around the world, thus reducing the load.
With Cloudflare, in fact, loading a website can gain up to yeezy 350 boost v2s 50% in. Terms of speed since the CDN will use the contents stored in the geographically closest server.
How does Cloudflare work?
The CDN To do this, Cloudflare implements a series of security measures such as. IP blocking and CAPTCHA to block potentially malicious traffic.
Additionally, the “ Checking your browser before accessing” warning is also Cloudflare’s work, testing visitors to ensure they are not bots.
