This is a repackaged open source software product wherein additional charges apply 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.
Overview
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 Inc.
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: the stock /etc/squid/squid.conf allows only localhost and denies every other client (http_access deny all), so although the image firewall and the 1-Click security group pre-open TCP 3128, no remote client can use the proxy until you add ACLs for your networks (for example http_access allow localnet) - a deliberate customer configuration step; narrow the security group's 3128 rule to those client CIDRs when you do, so the instance is never 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
- Production-ready: systemd-managed Squid; tune ACLs and cache in /etc/squid/squid.conf.
- Security-hardened at build time: minimal packages, key-only SSH, IMDSv2-only, deny-all proxy policy - the stock squid.conf allows only localhost (http_access deny all), so the pre-opened TCP 3128 cannot be used as an open proxy until you add your own ACLs.
- Continuously patched: rebuilt, vulnerability-scanned, and republished on a regular cadence.

Pricing
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
Dimension | Cost/hour |
|---|---|
c7i.xlarge Recommended | $0.46 |
c7i.4xlarge | $1.84 |
c7i.2xlarge | $0.92 |
Dimensions summary
You pay by the hour for the running instance, with the rate tied to the EC2 instance size you launch. Three sizes are offered: c7i.xlarge (4 vCPU / 8 GiB), c7i.2xlarge (8 vCPU / 16 GiB), and c7i.4xlarge (16 vCPU / 32 GiB). Larger instances carry higher hourly software rates because pricing scales with vCPU count. Charges accrue only while an instance runs and stop when you terminate it. There is no subscription or minimum. AWS infrastructure charges are separate and billed by AWS.
Top-of-mind questions for buyers
Each unit is one running EC2 instance of the size you launch, metered per hour. The c7i.xlarge gives 4 vCPU / 8 GiB, c7i.2xlarge gives 8 vCPU / 16 GiB, and c7i.4xlarge gives 16 vCPU / 32 GiB. The hourly software rate scales with vCPU count.
Software charges accrue only while an instance runs. When you terminate the instance, charges stop. There is no subscription or minimum. Note that stopped instances may still incur AWS storage fees for the attached EBS volume, which AWS bills separately.
The software charge covers image hardening, continuous patching, vulnerability scanning, and business-day support. The underlying open-source Squid software remains free. AWS bills compute, storage, and network usage separately under your own AWS agreement. A single instance uses one EC2 instance and one gp3 EBS volume.

Amazon Machine Image (AMI)
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.
Additional details
Usage instructions
- Launch from AWS Marketplace (1-Click or EC2 console).
- Connect via SSH with your EC2 key pair: ssh -i <key> ec2-user@<public-ip>. Root login is disabled; use sudo.
- Edit /etc/squid/squid.conf to set your ACLs (the stock config allows only localhost and denies all other clients; e.g. uncomment http_access allow localnet), then: sudo systemctl restart squid. The image firewall and the 1-Click security group pre-open TCP 3128 - narrow the security group's 3128 rule to your client CIDRs when you enable access.
- Verify: sudo systemctl status squid.
- Sensitive data: there are no passwords or secrets anywhere in this product. Logs under /var/log may contain client IPs - treat as personal data.
- Backup: snapshot the EBS volume (it contains all configuration and data).
- Resources: a single instance uses 1 EC2 instance and 1 gp3 EBS volume; no other AWS resources are created.
- Support: support@dcassociatesgroup.com .
