stackArmor, a Quantum Sky company, invented the ATO Accelerator category and has enabled 200 + systems to achieve FedRAMP, FISMA, CMMC 2.0, and DOD cATO, all in as little as 40% of the typical time and cost. Our ThreatAlert® platform combines “in-boundary” zero-trust security with automated compliance workflows to give you full control over your cloud authorization. From initial architecture and DevSecOps automation through 24/7 Continuous Monitoring, our end-to-end delivery team—builders, engineers, and compliance experts—partners with ISV CTOs, federal agencies, and defense contractors to meet stringent standards (FedRAMP High, DISA STIG, ISO 27001, NIST, DHS, FFIEC, FERPA, CMMC). We support container, serverless, and VM environments across AWS, Google Cloud, and Azure. Our newest flagship, The Armory, is a FedRAMP High–ready platform built on Google Cloud, purpose-built to accelerate mission-critical workloads in government and regulated industries. Let’s talk about how stackArmor can engineer certainty into your next ATO. Learn more at https://stackarmor.com.
