About
Phylum is an automated software supply chain defense platform that analyzes open-source packages for malicious code, vulnerabilities, license risks, and typosquatting attacks before they enter development or production environments. The platform operates as a policy enforcement layer between developers and public package registries, inspecting every package version against a continuously updated threat model that includes behavioral analysis, author reputation, and code similarity checks. Phylum's analysis runs at the registry level and at the point of installation, giving organizations defense-in-depth without requiring developers to change their workflows significantly.

About
Signifyd is a fraud prevention and commerce protection company founded in 2011 by Rajesh Ramanand and Michael Liberty, headquartered in San Jose, California. The company's core product is a machine-learning-powered fraud platform that evaluates every order placed on an e-commerce site in real time, assigning a confidence score and a financial guarantee: if Signifyd approves an order and it turns out to be fraudulent, Signifyd reimburses the chargeback — shifting the liability from the retailer to Signifyd. This chargeback guarantee model fundamentally changes the economics of fraud prevention, allowing merchants to approve more orders with confidence rather than declining borderline transactions out of caution.
