It replaces the patchwork of vendors and integration work most enterprises maintain today. It also features Netlify Database, a serverless Postgres solution with automatic, zero-config provisioning and Git-integrated branching. This ensures every Deploy Preview receives its own database branch forked from production data. Because schema and code always ship together, teams can test and collaborate on live data without manual staging or the risk of broken deployments.. Visibility and security are built into the core of the platform so everyone deploys to the same secure environment. Integrated Observability provides real-time insights into traffic, performance, and function health without the need for external tools. Reliability is guaranteed through instant rollbacks and compliance with SOC 2 Type II, GDPR, HIPAA, and PCI DSS Level 1. Every enterprise deployment is backed by 24x7 priority support to ensure the total stability of your modern web presence. By removing the infrastructure plumbing of the web, Netlify empowers organizations to focus on building the next generation of full-stack software.
