Cybersecurity Startup Azure Cloud Acceleration

Project Overview

Greenfield build: no pre‑existing cloud resources or network layout.

Goal: deliver a secure, highly‑available Azure foundation that can scale with a cloud‑native SaaS offering focused on automated endpoint security scanning.

Core workloads:

• React‑based frontend web app
• Containerised backend APIs & Azure Functions for event‑driven jobs
• Managed PostgreSQL database, blob storage, and service‑to‑service messaging

Key non‑functional drivers: private networking, modular IaC, cost‑efficient PaaS, fast & reliable CI/CD.

The client needed a secure, highly-available cloud foundation for their cybersecurity SaaS product with zero pre-existing infrastructure.

Key challenges included:

• Zero infrastructure to start: everything—from VNet design to pipelines—had to be stood up from scratch.
• Strict security posture: traffic must remain inside the VNet; external exposure limited to the web front door.
• Speed to market: engineering team needed daily deployments without manual gating.
• Cost control: avoid over‑provisioned VMs; prefer consumption‑based PaaS where possible.
• Robust governance: ensure repeatability across dev / staging / prod without drift.

Our Solution:

• Modular Terraform IaC: Separate Git repos & modules for networking, compute, messaging, storage, monitoring.
• Private Endpoints: Private DNS for every PaaS resource that supports them.
• GitHub Actions‑driven CI/CD: Automated infrastructure and application pipelines with hardened self-hosted runners.
• Segregated VNet architecture: Subnets for Web, APIs/Functions, Data, CI/CD runners with NSGs enforcing east-west isolation.
• Zero‑Trust security controls: Entra ID integration, managed identities, TLS 1.2+, and continuous audit via Azure Monitor.
