This product has charges associated with it for image hardening, maintenance, and support. Squid caching proxy on Amazon Linux 2023, security-hardened for production: minimal package set, SSH key-only access, IMDSv2-only, and continuously patched images.
Squid Proxy (Hardened) on Amazon Linux 2023 is a production-ready, security-hardened image of the Squid caching and forwarding web proxy, maintained and supported by Derek Coleman & Associates Incorporated.
This is repackaged open-source software. Squid is developed by the Squid Project and is distributed under the GNU General Public License v2 or later. This product bundles unmodified upstream Squid on a hardened Amazon Linux 2023 base; the charges associated with this listing are for image hardening, continuous patching, vulnerability scanning, and business-day support - not for the underlying open-source software, which remains free.
Hardening baseline: minimal package footprint, SSH key-only access (password authentication disabled), IMDSv2 enforced, and a deny-all default proxy policy (Squid ships denying all client access; defining your ACLs in /etc/squid/squid.conf and opening TCP 3128 to trusted CIDRs is a deliberate customer configuration step, so the instance cannot be abused as an open proxy). Images are rebuilt, scanned for HIGH and CRITICAL vulnerabilities, and republished on a regular cadence so that new launches start current. Manage the service with systemd: sudo systemctl restart squid.
Highlights
Security-hardened at build time: minimal packages, key-only SSH, IMDSv2-only, proxy port firewalled to trusted CIDRs.
Continuously patched: rebuilt, vulnerability-scanned, and republished on a regular cadence.
Production-ready: systemd-managed Squid; tune ACLs and cache in /etc/squid/squid.conf.

You pay by the hour based on the EC2 instance size you run. Three options let you match compute to your workload: c7i.xlarge, c7i.2xlarge, and c7i.4xlarge. These are the same hardened Squid Proxy image on different instance sizes. The hourly software rate rises as instance size increases, since larger instances carry more vCPUs. Billing is metered and appears on your AWS invoice, with no separate vendor contract needed. Pick the smallest size that meets your traffic needs, and scale up by choosing a larger instance when demand grows.
Top-of-mind questions for buyers
What compute do the c7i.xlarge, c7i.2xlarge, and c7i.4xlarge sizes give me?
Each size runs the same hardened Squid Proxy image on a different amount of compute. The c7i.xlarge has the fewest vCPUs, the c7i.2xlarge doubles that, and the c7i.4xlarge doubles again. Pick the size that matches your expected proxy traffic and connection load.
Am I charged when the proxy instance is stopped?
The hourly software rate meters running time only. A fully stopped instance stops accruing software charges. You may still pay underlying AWS storage fees for the attached volume while the instance is stopped, but the Squid Proxy software charge applies only while the instance runs.
How do I move to a larger instance size as my traffic grows?
Each size is a separate hourly dimension, so scaling is manual. You launch the same hardened image on a larger instance type when demand rises. Billing switches to that size's hourly rate automatically once the new instance runs. There is no automatic tier upgrade within a single instance.

An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
[Security] Refreshed image: rebuilt on the latest hardened Amazon Linux 2023 baseline; all OS packages current at build.

Usage instructions
Launch from AWS Marketplace (1-Click or EC2 console). Connect via SSH: ssh -i <key> ec2-user@<public-ip>. Edit /etc/squid/squid.conf to set your ACLs (Squid denies all by default), then: sudo systemctl restart squid, and open TCP 3128 to trusted CIDRs only. Root login is disabled; use sudo. There are no passwords anywhere in this product.
