Simplesense STIG Hardened AMIs are pre-configured Amazon Machine Images (AMIs) designed to meet Department of Defense (DoD) compliance requirements for use on AWS EC2 instances. The AMIs are hardened according to Defense Information Security Agency (DISA) Security Technical Implementation Guidelines (STIGs) and are continuously updated as new STIGs are released. The product was developed to address a recurring challenge faced by defense contractors working on AWS: each time a new EC2 instance is spun up, it must be brought into full compliance for an Authority to Operate (ATO) on the defense network. Simplesense pre-applies this hardening to reduce the duplicate labor involved in achieving and maintaining compliance. Available OS images include: - Amazon Linux 2 - Amazon Linux 2023 - Ubuntu Pro FIPS 22.04 LTS Each image is scanned for validation using industry tools to confirm the secure baseline. The AMIs are available for purchase through the AWS Marketplace and are documented via a dedicated developer portal. They are intended to support DoD programs requiring rapid implementation, integration, and compliance on AWS cloud infrastructure, including scenarios involving Operational Technology (OT) and Control Systems (CS) connected to defense networks.
