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.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.

Dimensions summary
You pay by the hour for this hardened Rocky Linux 10 image running on ARM64 (Graviton) instances. Pricing is not tiered. Instead, each dimension maps to a specific AWS instance type, so your rate follows the instance you launch. Options span general-purpose, compute-optimized, memory-optimized, storage-optimized, and metal families, sized from nano and medium up to 48xlarge and bare-metal. Larger instances carry higher hourly rates. You choose the instance that fits your workload, and the software fee bills alongside standard AWS infrastructure charges. Only usage you run is charged, with no upfront commitment.
Top-of-mind questions for buyers
The rate is a software fee for the hardened Rocky Linux 10 ARM64 image running on that specific instance. It bills per running hour and appears alongside standard AWS infrastructure charges. Each dimension matches one AWS Graviton instance type, so your rate follows the instance size you launch.
The hourly software fee meters running time. A fully stopped or powered-off instance does not accrue the software charge. Underlying AWS storage or other resource fees may still apply while the instance is stopped, but the image licence only meters hours the instance actually runs.
Citadel publishes refreshed images on a monthly patch cycle, with an expedited path for critical updates. Adopting a new release does not change how you are billed. You still pay the hourly rate for the instance type you run. Confirm the current release on the Marketplace listing before launch.

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
This is the initial release of the Rocky Linux 10 hardened image. It includes 300+ security controls pre-applied to the operating system and all latest updates as of this build. No extra software is included.

Usage instructions
- Launch the image inside your secure VPC.
- Scope access to trusted IPs only. Avoid exposing the instance directly to the internet.
- Use AWS Systems Manager Session Manager or connect via VPN if possible.
To connect via SSH: ssh rocky@<your-ec2-public-ip>.
Ensure port 22 is open in your security group and locked down to your IP.
No additional steps are required. The system is already fully hardened and ready to use.
