Yes, of course we’re faster. But we’re also more secure.
Stop choosing between speed and security. Here’s how Fastly customers get better security AND improve performance (and reduce complexity and save money too).
Building in Real-Time with Pushpin
We are excited to announce that Pushpin is now part of the Fast Forward program! It acts as a proxy server that pins client connections open, making it easy to build real-time API endpoints.
ETags: What they are, and how to use them
How to optimize your ETags to speed up your site and reduce calls to your origin without requiring significant code refactoring or content overhaul.
Designing Next-Gen WAF Sites for your Organization
Flexible options for deploying Fastly’s Next-Gen WAF are critical for getting your security running effectively, quickly, and with the right structure for your organization.
Introducing Config Store: storing and updating configuration data at the edge just got better
Config Store is a low-latency, key-value data store. It simplifies storing configuration data at the edge allowing you to deliver faster app experiences.
Introducing Cloud WAF Terraform Support
Terraform, from HashiCorp, enables DevOps teams to deploy cloud infrastructure as code. Fastly supports Terraform across our product lines and today we’re excited to share enhancements to our Next-Gen WAF Terraform provider for our Cloud WAF deployment model which will further streamline operations for our secure DevOps users.
TLS Key Size: Why Bigger isn't Always Better | Fastly
TLS key size has a recommended length of 2048 bits, but that does not mean you can not go bigger or smaller. In this post, we explore the various TLS key sizes by examining the function of the TLS certificate and the cryptographic operations used by TLS.
Is it time for ECDSA certificates?
For 40 years, RSA certificates have been the industry standard for Transport Layer Security (TLS). But we’re seeing a shift – especially as the prevalence of high-traffic cyber attacks continues to grow.
Syntax highlight Fastly VCL files in Visual Studio Code
With Fastly’s new Visual Studio Code extension, Fastly Varnish Configuration Language (VCL), you can now syntax highlight Fastly VCL code.
Using Client Hints to Detect Disparities
Learn how User-Agent Client Hints work, explore privacy-related features and concerns, and how the partial adoption and incompleteness of this emerging standard can be used to detect behavior disparities.
Secure multi-cloud environments: Enterprise journey to the cloud
As organizations go through a digital transformation of their processes and how they engage with their customers, they are often ready for a multi-cloud environment.
Run your Next.js app on Fastly
With our new next-compute-js library, you can now host your Next.js application on our Compute@Edge platform – giving you the benefits of both the Next.js developer experience and our blazing-fast, world-wide edge network, and you don't even need an origin server.
No-origin, static websites at the edge!
Many of the world's websites are static, and Fastly’s content delivery network gets those pages from origin to visitors quickly. But what if we took the origin out of the equation?
OpenTelemetry part 4: Instrumenting Fastly Fiddle
We are very excited about OpenTelemetry. We wrote about why, and also about how to emit telemetry from Fastly's VCL services, and our new Compute platform. But OpenTelemetry's value truly shines when you add it to everything in your stack. What does that look like and is it worth it? We instrumented Fastly Fiddle, from top to bottom, to find out.
ESI and the story of libraries built for the edge
Traditionally, content delivery networks have been built upon a proprietary core product which is supported by equally proprietary add-ons such as image optimization and content filtering. Fastly has always done a bit better than this – from the beginning, building our network on the Varnish cache gave our customers the ability to fully program how requests were served at the edge. However, the constraints of VCL, the domain-specific language used to configure Varnish, meant that you were limited to only the features that we chose to offer.
Private Access Tokens: A CAPTCHA-less future | Fastly
At its core, Private Access Tokens present a privacy-respecting, anti-fraud and authorization framework. This blog post provides an overview of what it does and how developers can try it out with Fastly and Apple today.
iCloud Private Relay and what it means for customers
iCloud Private Relay is a new internet privacy service from Apple. With iCloud Private Relay, users with an iPhone, iPad, or Mac and an iCloud+ subscription can connect to and browse the internet and in a more secure and private way using Safari.
Migrated developer site to Compute@Edge | Fastly
If you build stuff on Fastly, chances are you spend a decent amount of time on our Developer Hub. Last month, we migrated it from our VCL platform to Compute. Here's how we did it and what you can learn from it.
Fastly's observability and monitoring: empowering smart delivery and high performance | Fastly
In this post, we break down our current observability offering and highlight some of the ways DevOps and SRE teams are using Fastly to investigate anomalies, improve performance and up-time, and engage in observability-driven development.
Inside Fastly: a look at our vulnerability remediation process
In this post, we present a look at our vulnerability remediation and engineering team and how they were able to roll out a recent fix for a QUIC/H2O vulnerability in under two weeks.
