On the security front, a new Managed Security Service ensures your websites and applications are protected for Next-Gen WAF customers. High performance edge storage is now offered as part of Compute@Edge and you can host Remix applications on our Compute platform.

Ending the year out strong, our product portfolio has grown to include even more network services, security, and observability capabilities. On the security side, Next-Gen WAF now supports Log4Shell attack signal within SmartParse and GraphQL by default to keep up with the evolving threat landscape. To protect against DDoS attacks TLS Support ECSDA Certificates are now available in the Fastly UI. For network services, Automation Tokens and customer headers for health checks entered general availability. These features both streamline service management workflows. Two new features, Websockets and Image Optimizer self-enablement are also available in the Fastly console. Google Cloud Storage, BigQuery, and Pub/Sub logging endpoints now do not require saving service keys in the FAstly app, so customers can manage temporary credentials for logging endpoint configuration.

This quarter our teams concentrated on Fastly Next-Gen WAF, Cloud WAF, and Image Optimizer capabilities. Along with our Next-Gen WAF edge deployment reaching general availability (GA) in the Essentials package, customers can also enjoy the additions of CVE signals and Log Sampling Time Series improvements. Our integration with AWS Lambda enables developers to start a Lambda function to activate the Fastly Next-Gen WAF agent. Our next-gen WAF cloud deployment now supports multi-origin workspace and will continue to do so for all new instances moving forward. Fastly’s Image Optimizer continues to reduce infrastructure costs and improve end-user experience by supporting AVIF format, a new image format meant for compression and lightning quick delivery.

As the weather heats up, so does our product portfolio. Observability has been a top priority and we are proud to announce Origin Inspector and Domain Inspector in General Availability, which can be self-enabled straight from the Fastly UI. On the security front, Fastly Next-Gen WAF Edge Deployment is now in GA and CVE signals are also available for Essential Plan customers. Our long time product, Image Optimizer, also got a tune up and now offers feature trim-color, which adds a border to an image without sacrificing end-user performance. Last but not least, JavaScript SDK has been added to Compute@Edge’s supported languages.

The new year is in full swing with our Q1 releases. Fastly continues to play a leading role in defining the future of the internet, including HTTP/3 & QUIC, the next version of the Hypertext Transfer Protocol which we now support. On the security side the Fastly Next-Gen WAF (powered by Signal Sciences) can now be deployed at the Fastly edge. Other security releases include custom response codes in GA and agent support for Arm-based devices in LA. GraphQL Inspection has also reached limited availability and can be combined with Fastly Next-Gen WAF (powered by Signal Sciences) to provide more API coverage. Lastly Fastly 101 is live in our documentation where customers can follow project-based tutorials.

As another year ends, we reflect on Q4 releases. We are delighted to open our Compute@Edge Free Trial with $50 in credits so that you can test our platform. Simply navigate to the Compute tab in the Fastly UI to start a service. While you’re at it, consider adding Origin Inspector to your observability strategy. This new update provides real-time and historical datasets and visualization of your origin traffic to the Fastly edge cloud network. On the security side, Signal Sciences Advanced Rate Limiting customer-defined client identifiers has more than doubled to 25,000, arming customers in the premier package with more effective protection. Cloud WAF VPC 2.0 was also released and allows each deployment to handle more simultaneous connections from Cloud WAF to a single origin.

On the security side, next-gen WAF customers can request health checks on their service and receive expert advice on how to improve their deployment. Rate limiting is now available in two options: Fastly’s Edge Rate Limiting and Non-IP Rate Limiting. Fastly’s Edge Rate Limiting helps to sustain uptime during automated attacks. Non-IP Rate Limiting enables customers to include non-IP values such as cookie value to the rate limit. Lastly, Subscriber Provided Prefix has graduated to General Availability, allowing users to maintain their own IP addresses.

As another quarter ends we are happy to announce the following updates to our product portfolio. On the security side, we now offer a variety of TLS certificate options including GlobalSign OV and multi-domain. Customers can also manage Fastly TLS and Platform TLS through Terraform.
