Why is a Content Delivery Network (CDN) like Cloudflare essential for my business website?
Key Takeaway
At Strategus, we’ve moved some of our clients to Cloudflare because it is a fundamental tool for success in today’s digital environment. Cloudflare acts as a digital bodyguard and high-speed delivery service for your website. Its core function is to make your site faster and more secure for every single visitor, no matter where they are in the world. This can lead to a better user experience, higher conversion rates, and a stronger bottom line for your business.

What is Cloudflare and how does it work?
To begin with, let’s demystify Cloudflare. In simple terms, Cloudflare is a global network of servers that sits between your website’s host and your visitors. When a user requests to see your website, that request doesn’t go directly to your server; it’s routed through the closest Cloudflare data centre. Think of it as a reverse proxy, a smart filter that handles traffic before it ever reaches your website’s origin.
This collaborative approach allows Cloudflare to perform two critical tasks: it makes your website faster by caching and serving content from a location closer to your visitors, and it protects your site by filtering out malicious traffic and cyber threats. This is a robust solution that provides peace of mind and measurable improvements.
How does Cloudflare make my website faster?
Next, we need to address the speed factor. In the digital world, every second counts. According to Google, the probability of a mobile site bouncing increases by 32% as page load time goes from one second to three seconds. Cloudflare combats this directly through its core function as a Content Delivery Network (CDN) and a suite of performance-enhancing tools.
Caching and Content Delivery Network (CDN)
A CDN is a network of globally distributed servers. Cloudflare’s network spans over 300 cities in more than 120 countries, including local footprints in Christchurch and Auckland. When a visitor first comes to your site, Cloudflare caches a copy of your static content—such as images, CSS, and JavaScript files—on a server close to them. The next time a visitor requests that content, it’s served from the nearest Cloudflare server, not your origin server, drastically reducing latency. This means your website loads at lightning speed, no matter where your visitor is.

Performance Optimisation Tools
Beyond the CDN, Cloudflare employs a variety of features to further optimise performance:
- Polish: This feature automatically optimises your images by compressing them and converting them to more efficient formats like WebP, without any loss of visual quality. This can significantly reduce page size, which is especially critical for mobile users.
- Minification: Cloudflare can automatically minify your HTML, CSS, and JavaScript files by removing unnecessary characters and comments. The result is a smaller file size that loads faster.
By implementing these strategic optimisations, we ensure your website delivers a seamless and rapid user experience that keeps visitors engaged.
What security threats does Cloudflare protect against?
Cybersecurity threats are a constant reality, with an estimated 170 billion cyber threats blocked by Cloudflare’s network each day. Cloudflare provides a multi-layered defence system to protect your online assets.
Protecting Your Website from DDoS Attacks
A Distributed Denial of Service (DDoS) attack is a malicious attempt to disrupt your website’s normal traffic by flooding it with a huge volume of fake traffic from multiple sources. It’s like a digital traffic jam designed to crash your site. Cloudflare’s expansive network is built to absorb and filter this malicious traffic before it ever reaches your server, ensuring your website remains online and operational.
Web Application Firewall (WAF)
Cloudflare’s Web Application Firewall (WAF) acts as a powerful shield, inspecting all incoming traffic and blocking threats like SQL injection and cross-site scripting (XSS) attacks. It uses a continuously updated ruleset to identify and block common vulnerabilities, keeping your website’s code and data safe.
SSL/TLS Encryption
SSL/TLS encryption secures the connection between your website and your visitors, protecting sensitive data like passwords and credit card information, ensuring all data transmission is encrypted and boosting visitor trust—an important factor in both user confidence and search engine rankings.
How does Cloudflare provide real value to my business?
The benefits of Cloudflare go beyond just speed and security. Cloudflare provides the stability and intelligence required to thrive online.
Increased Reliability and Uptime
Downtime can be costly, both in terms of lost revenue and damage to your brand reputation. Cloudflare’s “Always Online” feature ensures that if your origin server unexpectedly goes down, a cached version of your site is still served to visitors, maintaining a consistent online presence. This is a critical component of a robust digital strategy.
Actionable Analytics and Insights
Cloudflare’s dashboard provides real-time analytics on traffic, threats, and performance. This gives us the precise insights we need to make informed decisions and continuously optimise your site. We can identify traffic trends, understand visitor behaviour, and even spot and manage bot traffic.
