Powering the best of the internet

Fastly is a cloud computing service provider specialising in edge computing solutions and content delivery networks (CDN). Its platform is designed to help websites and applications deliver content to users more quickly and securely. Fastly’s services accelerate the pace at which digital content, such as web pages, images, and video streaming, can be accessed by users around the globe. This is achieved by caching content in servers closer to the end-users, reducing latency and improving load times. Additionally, Fastly provides a range of security features, including DDoS mitigation, web application firewalls, and SSL/TLS encryption, to protect websites and applications from cyber threats.

What is Fastly?

Fastly is a leading-edge cloud platform that offers a comprehensive suite of services designed to optimize the performance, security, and scalability of digital experiences. As a content delivery network (CDN), Fastly accelerates the delivery of web content by caching it closer to users worldwide, significantly reducing latency and improving load times. Beyond speeding up content delivery, Fastly provides advanced security measures, including DDoS protection, web application firewalls, and secure TLS encryption, ensuring that digital assets are safe from cyber threats.

Fastly’s platform is built for flexibility and innovation, supporting real-time analytics and edge computing capabilities. This allows businesses to make data-driven decisions and deploy custom logic at the network edge, closer to where users are. For developers, Fastly offers programmable tools and an API-first approach, making it easier to integrate and automate their workflows.

As a Fastly partner, we help our clients achieve faster website load times, bolster their cybersecurity, and provide a superior user experience. Whether you’re managing high traffic volumes, looking to improve your website’s performance, or aiming to secure your online presence, our partnership with Fastly empowers us to meet these challenges head-on.

What is a Web Application Firewall?

Fastly’s Web Application Firewall (WAF) is an advanced security measure designed to shield websites and applications from various online threats by monitoring and filtering HTTP traffic. It provides real-time defense against attacks such as SQL injection, cross-site scripting (XSS), and more, using up-to-date security rules for threat identification and mitigation.

Businesses can customise the WAF according to their specific needs, adjusting rules and creating custom protections for unique vulnerabilities. Integrated into Fastly’s edge cloud platform, the WAF minimises latency, ensuring security measures do not affect application performance. It also delivers comprehensive analytics and insights, allowing businesses to understand and respond to security threats effectively.

The WAF’s API-first approach facilitates easy integration and automation of security tasks, providing flexibility as security demands evolve. Designed to scale with any size or volume of traffic, Fastly’s WAF is suitable for businesses at any stage of growth, offering a robust solution to modern web security challenges with its blend of customisability, performance, and detailed threat intelligence.

The Fastly Next-Gen WAF is a hybrid software as a service (SaaS) solution with three main components. Signal Sciences developed this patented approach, which allows Fastly to easily scale and protect even the highest-volume applications and APIs without impacting performance.
