Google is the search giant turned full-stack AI infrastructure player, building its own TPU chips, the Gemini models, and the Gemini Enterprise Agent Platform to compete with AWS and Microsoft.
VPN
A Virtual Private Network (VPN) lets you route your internet access through a specialized server that keeps your sensitive information private.
Tokenization
Tokenization is one of the ways that backends protect sensitive information, like credit cards or social security numbers.
Snyk
Snyk helps developers make sure that the code they're writing is secure.
Okta
Okta is an enterprise-focused identity provider: they take care of managing usernames, passwords, and permissions.
