4 characteristics of developer-friendly cloud security controls

If you’re evaluating web application security tools exclusively for their security requirements, you may be missing one of the most essential opportunities to successfully grow your secure DevOps culture: developer-centricity.

Fastly’s security DNA: a look at our culture of safety, privacy, and trust

Fastly's heritage of security runs deep — far beyond our portfolio of web application and API security products. Our philosophy of developer empowerment, focus on community, and values-driven culture each contribute to our security DNA in an important way. And we'd like to tell you how.

State at the edge

With the introduction of Compute@Edge, Fastly provides a richer model for the CPU. WebAssembly, powered and secured by the Lucet compiler and runtime, unlocks essentially arbitrary code execution within each request lifecycle. This raises the immediate question: what would a richer model for memory, or state, look like?
