This product has charges associated with the pre-built security hardening and recurring maintenance. Deploy a Rocky Linux 10 virtual machine with 300+ security controls already applied. Start secure. Stay secure. Save weeks of work.
Overview
This Rocky Linux 10 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.

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. Alternatively, you can pay upfront for a contract, which typically covers your anticipated usage for the contract duration. Any usage beyond contract will incur additional usage-based costs.

Dimensions summary
You pay by the hour for this hardened Rocky Linux 10 operating system, billed per running instance. Each dimension maps to a specific AWS ARM-based (Graviton) instance type. Pricing scales with the size and family you pick. Compute-optimized (c-series), general-purpose (m-series), memory-optimized (r-series and x-series), storage and I/O families (i-series, im-series, is-series), burstable (t4g), high-performance compute (hpc7g), and graphics (g5g) options are all available. Larger sizes within a family carry higher hourly rates. Metal variants run on dedicated hardware. You choose the instance that fits your workload and pay only for hours used.
Top-of-mind questions for buyers
Each unit is one running EC2 ARM (Graviton) instance of the type you pick, billed per hour of run time. The hardened Rocky Linux 10 software charge meters running hours only. A stopped or powered-off instance does not accrue this software charge, though underlying AWS storage fees may still apply.
You pay the hourly rate tied to the specific instance type you launch. Moving from a small size to a larger one in the same family raises your hourly rate. The change is not automatic; you choose the instance type at launch. You pay the new rate only while that larger instance runs.
The price covers the hardened Rocky Linux 10 operating-system baseline as packaged for this release. Your own applications, cloud account configuration, and any changes made after deployment sit outside the image scope. The verification record applies to the declared OS baseline, not your deployed environment.

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.
