Why a CDN is Required for Website Security & Performance In 2023

In the beginning, when your business only has a website, it is easier to handle its online presence. However, when you want to grow- you attract more visitors to the website, make more sales, and acquire more customers. But what no one except- as the online presence grows – problems and risks come along 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 slowed page loading times, loss of 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 function as a business, it’s not worth it.

Several technologies help to build a solid foundation for website security. SSL certificate is a technology that ensures site security and privacy. Web Application Firewall (WAF) is another implementation that blocks malicious activities and keeps information secure. Since the popularity of the internet has exploded, many companies have taken advantage of the CDN for website security. Let us delve deep into how CDN improves websites’ speed, security, and performance.

What is CDN?

A Content Delivery Network (CDN) is a collection of servers that can distribute content to users more efficiently and reliably than possible if the website’s 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 to deliver your website’s content to users more quickly. This is useful if you have a lot of traffic and want to minimize the time for your pages to load.

Improves Performance

By avoiding loading your entire website from scratch every time someone visits your page, CDN can reduce the time it takes for pages to load. Additionally, by caching copies of pages across multiple servers, CDN reduces the amount of bandwidth and storage space required to serve pages.

The best CDNs use various techniques, like caching and geo-distribution, to help improve the delivery of your pages. It can reduce the load time for specific pages by as much as 50%.

Increase Audience Reach

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

Search Engine Optimization

Visitors on a slow website experience a lot of delays, which can make it difficult for them to complete the tasks they’re there to do. This can also lead to lower customer satisfaction ratings and less traffic. Websites that are fast load time have an advantage over their slower counterparts regarding SEO.

As CDN improves a website’s performance by decreasing the time it takes for the site to respond to requests from browsers, it positively improves the search engine ranking.

Better Security and DDoS Protection

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

When you visit a website, your computer sends requests for the webpage to the CDN’s servers. The CDN then distributes the webpage to its various nodes worldwide 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’s server cannot handle all of them at once.

 A CDN can help protect websites from DDoS (Distributed Denial-of-Service) attacks, which are when attackers bombard a site with traffic to make it crash.

This type of attack frequently occurs, especially against big companies and websites with high traffic volumes. By using a CDN, a website’s visitors can be sent to different servers worldwide, making it harder for an attacker to target just one server and flood it with traffic.

Wrapping Up

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 chances of data loss or theft when your website is hacked.

Low Rate DDoS Attack

9 of 10 sites on the AppTrana network have faced a DDoS attack in the last 30 days.
Some DDoS attacks could readily be blocked by rate-limiting, IP reputation checks and other basic mitigation methods.
More than 50% of the DDoS attacks are employing botnets to send slow DDoS attacks where millions of IPs are being employed to send one or two requests per minute..
Key takeaways include:

  • The mechanics of a low-DDoS attack
  • Fundamentals of behavioural AI and rate-limiting
  • Surgical mitigation actions to minimize false positives
  • Role of managed services in DDoS monitoring
