Why a CDN is Required for Website Security and Performance in 2022

In the beginning, when your business has only one website, it is easier to manage its online presence. However, when you want to grow, you attract more website visitors, make more sales, and acquire more customers. But as online presence grows, problems and risks come with it.

As the business grows, hackers target and attempt to break into the website to steal your data or damage your website’s reputation. Poor website security can also lead to slow page load times, lost customers, and lost revenue.

Website security is important, but it should never come at the expense of site performance. If a website’s security measures interfere with its ability to operate as a business, it’s not worth it.

Several technologies help establish a solid foundation for website security. The SSL certificate is a technology that guarantees the security and confidentiality of the site. Web Application Firewall (WAF) is another implementation that blocks malicious activity and protects information. Since the popularity of the Internet has exploded, many businesses have taken advantage of CDN for their website security. Let’s take an in-depth look at how CDN improves website speed, security, and performance.

What is CDN?

A Content Delivery Network (CDN) is a collection of servers that can deliver content to users more efficiently and reliably than would be possible if website content were served from the user’s local computer. This is especially important for websites that serve large files, such as media streaming services or e-commerce sites.

Why is CDN important for performance and security?

A content delivery network can help deliver your website content to users faster. This is useful if you have a lot of traffic and want to minimize the loading time of your pages.

Improves performance

By avoiding loading your entire website each time someone visits your page, CDN can reduce page load times. Additionally, by caching copies of pages across multiple servers, CDN reduces the amount of bandwidth and storage space needed to serve pages. The best CDNs use a variety of techniques, like caching and geocasting, to help improve your page delivery. It can reduce the loading time of specific pages by up to 50%.

Increase audience reach

The CDN makes it more cost effective and easier to deliver your content to visitors in locations away from the main servers. This means that users from different countries won’t have to wait too long for your page to load and they will get accurate information about the products they are looking at.

search engine optimization

Visitors to a slow website experience many delays, which can prevent them from completing the tasks they are there for. It can also lead to lower customer satisfaction ratings and lower traffic. Websites with fast loading times have an advantage over their slower counterparts when it comes to SEO.

As CDN improves the performance of a website by reducing the time it takes for the site to respond to browser requests, it positively improves search engine rankings.

Better security and DDoS protection

In addition to improving performance, caching can help reduce spam comments and minimize bandwidth usage during peak hours.

When you visit a website, your computer sends requests for the web page to CDN servers. The CDN then distributes the webpage to its various nodes around the world so that you can still interact with the website even if the main server is down or overloaded. This is useful in cases where you have many visitors and the website server cannot handle them all at once.

A CDN can help protect websites from Distributed Denial-of-Service (DDoS) attacks, which occur when attackers bombard a site with traffic to crash it. This type of attack happens frequently, especially against large companies and high-traffic websites. By using a CDN, visitors to a website can be sent to different servers around the world, making it harder for an attacker to target a single server and flood it with traffic.

Execution Risk based WAF like AppTrana Industry at the edge of the network with CDN can prevent a wide range of threats by filtering our malicious activities.


Overall, using a CDN for websites has long been considered one of the best ways to improve website security. it helps protect against traditional web attacks and reduces the risk of data loss or theft when your website is hacked.
