Security-First AI Platform on Azure

From zero to encrypted-by-default platform with AKS, PostgreSQL, and Azure Front Door

We built Boulevard Tech's security-first cloud platform from the ground up on Azure, enabling compliant, encrypted-by-default operations while preserving rapid delivery for AI features.

Highlights

What we delivered

  • Encryption at rest everywhere with customer-managed keys (Key Vault/HSM)
  • AKS with private networking and Azure Front Door (WAF) for global ingress
  • Managed PostgreSQL (HA, PITR) with private endpoints and CMK

Context

The situation

As an AI legal tech company handling sensitive documents, Boulevard Tech required strong data protection, audit readiness, and a scalable foundation to support fast product iteration.

Provisioned a greenfield Azure platform with AKS, Azure Front Door (WAF), and Azure Database for PostgreSQL; enforced encryption at rest using customer-managed keys; implemented private networking, identity/RBAC, and policy guardrails; codified everything with Terraform; and established a CI/CD pipeline for secure, automated deployments.

Challenges and goals

What had to be solved

Protecting sensitive legal data

Implementing CMK-backed encryption, secret management, and auditable controls without slowing teams.

Zero-trust networking

Private clusters/endpoints, segmented VNets, and WAF-protected ingress.

Compliance readiness

Aligning to GDPR/SOC 2/ISO 27001 practices while keeping delivery velocity high.

Goals

  • Security-first foundation with customer-managed keys and encryption at rest across services
  • Reliable, scalable AKS and managed PostgreSQL with private endpoints
  • Global, protected ingress via Azure Front Door with WAF

Implementation

How we did it

  1. Foundations: Landing zone, VNet, private endpoints, Key Vault with CMK/HSM and key rotation
  2. Data: Azure Database for PostgreSQL (HA, backups/PITR) with private access and CMK encryption
  3. Compute: Private AKS cluster with RBAC, pod security/policies, managed identities
  4. Edge: Azure Front Door (WAF) to private ingress, TLS everywhere
  5. Guardrails: Azure Policy, Defender for Cloud, logging and audit
  6. Handover: CI/CD integration and operational runbooks
