Microsoft Presidio VPC Private Subnet Proxy Deployment

The deployment was live, but air-gapped from the world. This is the core of a Microsoft Presidio VPC Private Subnet Proxy setup—fast, secure, and invisible to untrusted networks.

Microsoft Presidio provides data protection with deep PII anonymization. Running it inside a Virtual Private Cloud (VPC) with a private subnet removes public exposure. But data still needs to move. That’s where a proxy deployment comes in, bridging internal services to selected external endpoints without opening the subnet to direct internet traffic.

In this architecture, Presidio services stay in the private subnet. You integrate an internal proxy—often an API Gateway or NAT instance—inside the VPC. Requests flow from Presidio through the proxy, out to the internet or other VPCs, and back again. By keeping Presidio separated from public IP ranges, you reduce attack surface and improve compliance posture.

Deployment steps are straightforward but exacting:

1. Provision the VPC with private subnets in multiple availability zones.
2. Place Presidio containers or pods in the private subnet.
3. Set up the proxy—AWS NAT Gateway, Azure NAT, or a custom proxy service—inside a public subnet but with controlled routing rules.
4. Configure routing tables so Presidio instances can only reach external resources through the proxy.
5. Apply strict network security groups to block all inbound traffic to Presidio from public IPs.
6. Validate end-to-end encryption between Presidio, the proxy, and destination endpoints.

This deployment pattern is critical for scenarios where sensitive data scanning and anonymization cannot risk unfiltered network exposure. It ensures Presidio’s APIs remain reachable only by approved internal systems while still allowing outbound access when required.

Optimize for low latency by placing the proxy close to Presidio workloads. Monitor for packet drops and tune connection pools to handle burst loads. Regularly audit firewall rules and IAM permissions so the proxy cannot be abused as a backdoor.

A Microsoft Presidio VPC Private Subnet Proxy deployment is not just secure—it’s operationally clean, simple to maintain, and performs at scale. Start your own secure Presidio deployment with tight private subnet controls and see how quickly you can scan and anonymize sensitive data without risking exposure.
