This product has charges associated with the pre-built security hardening and recurring maintenance. Deploy a Debian 12 virtual machine with 300+ security controls already applied. Start secure. Stay secure. Save weeks of work.
Overview
This Debian 12 image is a hardened virtual machine configured with over 300 security controls designed to protect cloud-based workloads from the start. Ideal for companies operating in regulated or sensitive environments, this image gives teams a secure and production-ready foundation out of the box.
Our hardened images are built using proprietary internal pipelines that automate and validate the implementation of critical security controls. Each control is carefully selected to reduce attack surface, enforce secure defaults, and help teams meet internal or external compliance expectations. No tools are pre-installed. The image is clean, consistent, and easy to integrate into any environment.
Use cases include deploying workloads in healthcare, finance, government, SaaS platforms, or any application where security is a priority. Default cloud OS images offer little to no security by default. Our hardened images save engineering teams weeks of effort, reduce risk from misconfiguration, and accelerate your ability to launch in secure environments. We are a US-based company with over four years of operation, trusted by enterprises and government agencies. All engineering and support work is performed by US-based employees.
Highlights
- Over 300 security controls are pre-applied to the base image to reduce vulnerabilities, enforce strong defaults, and simplify compliance. This saves teams weeks of manual effort and ensures consistency across deployments.
- Every image is built through our internal security pipeline and validated for integrity and reliability. You can deploy in minutes with confidence that your base operating system is secure and ready for production use.
- Backed by billions of compute hours and trusted by Fortune 500 and government teams. Our hardened images are the secure foundation for mission-critical workloads in regulated environments.

Dimensions summary
You pay by the hour based on the ARM-based EC2 instance type you run. Each dimension maps to a specific instance size, so the price scales with the compute, memory, and storage that instance provides. Smaller instances like t4g.nano bill at a lower hourly rate, while larger sizes such as m8g.48xlarge and metal instances bill more. The software itself is a hardened Debian 12 image; the hourly charge is added to your AWS infrastructure cost. Pick the instance family and size that fits your workload, then run it as long as needed.
Top-of-mind questions for buyers
The hourly rate covers the hardened Debian 12 software image, not the underlying compute. The image is secured using automated hardening tools built to NIST standards, with over 100 security controls enabled and monthly updates. You pay this software charge on top of your separate AWS infrastructure cost for the instance.
The software fee meters running instance-hours only. A fully stopped instance does not accrue the hourly software charge. Stopped instances may still incur separate AWS storage fees for attached volumes, but those come from AWS, not from this listing's software price.
Each dimension maps to one specific ARM instance size, and you are billed per hour for whichever you run. Larger sizes with more vCPUs, memory, or local storage carry higher hourly rates. Metal instances, which give dedicated physical hardware, bill at higher rates than shared virtual sizes.

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.
