License: MIT (Core)
Deployment:Docker / Kubernetes / SaaS
Data Model: PostgreSQL / Redis
Jurisdiction: USA 🇺🇸

1. The Executive Summary

What is it? Infisical is a secret management platform built for the modern cloud-native era. It eliminates the security risk of storing API keys and database credentials in .env files or git repositories. Unlike HashiCorp Vault, which is notoriously complex to operate, Infisical offers a developer-first experience with a sleek UI, CLI, and SDKs that "just work."

The Strategic Verdict:

🔴 For Legacy/On-Prem Only: Caution. While it supports on-prem, its strength lies in cloud-native workflows (Vercel, AWS, Kubernetes).
🟢 For DevOps & Platform Teams: Strong Buy. If you are struggling with "Secret Sprawl" across multiple environments (Dev, Staging, Prod), Infisical provides a centralized, audited source of truth.

2. The "Hidden" Costs (TCO Analysis)

Cost Component	HashiCorp Vault (Enterprise)	Infisical (Self-Hosted)
Licensing	$$$ (Complex tiered pricing)	$0 (MIT Core)
Operational Overhead	High (Requires dedicated experts)	Moderate (Docker/K8s standard)
Developer Friction	High (Steep learning curve)	Low (Intuitive UI/CLI)
Secret Rotation	Native (Strong)	Native (Growing support)

3. The "Day 2" Reality Check

🚀 Deployment & Operations

Architecture: Runs as a set of containers: Backend (Node.js), Frontend (Next.js), Postgres (Data), and Redis (Cache).
Scalability: Designed to run on Kubernetes. The stateless backend allows for horizontal scaling.

🛡️ Security & Governance

Encryption: Secrets are encrypted at rest and in transit. Infisical uses blind indexing, meaning the server doesn't know your raw secrets.
Compliance: SOC 2 Type II
