Government cloud security built to survive the ATO.
Cloud security and infrastructure for federal agencies, state governments, and defense contractors. FedRAMP-authorized architecture design, FISMA-compliant SIEM implementation, and Zero Trust infrastructure that passes authorization review and protects mission systems.
Government cloud security is not simply enterprise security with additional paperwork. The Authorization to Operate process requires documented security architecture before systems go live. FISMA defines the control baseline. FedRAMP governs which cloud services can be used and how. Every technical decision has a compliance consequence.
Yearling Solutions brings practitioners who have navigated federal authorization processes, designed GovCloud environments, and implemented SIEM and detection capabilities across classified-adjacent and unclassified mission systems. We design cloud security architecture that is built for ATO from the first diagram, not retrofitted after the fact.
Standards & Regulatory Context
The compliance landscape that shapes cloud security programs in the public sector.
FISMA & NIST RMF
Risk Management Framework system categorization, security control selection (NIST SP 800-53), and continuous monitoring requirements for federal cloud systems.
FedRAMP
Cloud service authorization requirements, FedRAMP-authorized service selection, and CSP assessment obligations for agency cloud deployments.
CMMC 2.0
Cloud security controls for Controlled Unclassified Information (CUI) environments in defense contractor programs.
CISA Zero Trust Maturity Model
Federal Zero Trust Architecture strategy and CISA maturity model alignment for cloud and network security modernization.
OMB M-22-09 (Zero Trust Strategy)
Federal Zero Trust implementation requirements and agency timelines for identity, device, network, application, and data pillars.
NIST SP 800-171 (CUI)
Security requirements for protecting Controlled Unclassified Information in non-federal cloud and on-premise systems.
What We're Seeing
The security realities driving conversations with public sector infrastructure leaders today.
SIEM gaps in FedRAMP authorization boundaries
Many agency cloud deployments have SIEM coverage of corporate networks but limited visibility into cloud infrastructure, container workloads, and serverless environments. Adversaries have learned to operate in the gaps.
Legacy system integration creating security debt
Government modernization projects that connect legacy on-premise systems to cloud infrastructure often create hybrid environments with inconsistent security controls and monitoring gaps that neither team owns.
Zero Trust mandates without implementation roadmaps
OMB M-22-09 created agency obligations that many are still translating into technical architecture. Organizations that approach Zero Trust as an infrastructure project rather than a risk-reduction program tend to invest heavily in tools that do not change actual risk posture.
Supply chain risk in cloud infrastructure
Dependency on commercial cloud services, third-party software, and open source components creates supply chain exposure for mission systems. CISA and NIST guidance on software supply chain security applies to government cloud deployments.
