Squid Proxy Server on Azure

Deploy a production-ready Squid proxy server on hardened Azure in minutes. Built for infrastructure and security teams who need to control, filter and log outbound web traffic from Azure workloads without spending days on installation, ACL configuration and OS hardening. Every image ships pre-patched, firewall-ready and validated.

Why Teams Deploy This Image

Locked-down environments need controlled egress. Whether you are meeting compliance requirements that mandate outbound traffic inspection, reducing bandwidth costs through caching, or giving isolated subnets a single audited path to the internet, Squid remains the industry-standard forward proxy, and this image removes the setup burden.

What You Get Out of the Box

• Latest stable Squid release, installed and enabled on first boot.
• CIS-aligned operating system hardening applied to the underlying OS.
• Access logging pre-configured in a format ready for Microsoft Sentinel or any SIEM ingestion.
• Support for authentication helpers (Basic, LDAP and Kerberos), ready to enable for your directory environment.

Common Use Cases

• Egress Control: Give private subnets a single, policy-enforced path to the internet.
• Compliance Logging: Maintain a complete audit trail of outbound web requests for regulated workloads.
• Bandwidth Optimisation: Cache repeated downloads such as operating system packages, container layers and software updates across a fleet.
• Web Filtering: Allow or block destinations using domain, category or time-based access control lists (ACLs).
• Development Environments: Reproduce corporate proxy conditions for realistic application testing.

Who This Is For

Cloud engineers, security teams, managed service providers and system administrators running Azure workloads that require governed outbound internet access—from single virtual machines to highly available proxy tiers behind an Azure Load Balancer.
