IT & Cybersecurity for Government Agencies & Contractors
Federal, state, and local organizations cannot compromise on security. ACS provides managed IT, cybersecurity, and government cloud support built around the frameworks you answer to: FISMA, FedRAMP, CMMC 2.0, and CJIS. We protect CUI and citizen data, keep mission systems online, and map your controls to what assessors actually test. Remote-first, nationwide.
Government IT has demands generic providers miss
The regulatory stack is unforgiving and the threats are relentless. These are the problems we solve for agencies and contractors every day.
CUI & citizen data exposure
A single exposed record can trigger CISA notifications, OIG findings, and lasting damage to public trust. We lock down CUI and PII end to end.
Downtime during mission operations
When a public-facing portal or case system fails, every minute affects citizens and agency credibility. We engineer for mission-hours uptime.
Misconfigured government cloud
GCC High, Azure Government, and AWS GovCloud each have specific authorization, data-residency, and access rules. We configure them the way FedRAMP and the DoD SRG require.
FISMA, FedRAMP & CMMC obligations
NIST 800-53 controls, FedRAMP authorization, CMMC 2.0 levels, and CJIS for law enforcement. We map your IT controls directly to the frameworks auditors test.
Secure telework & field access
Staff and contractors need access to sensitive data from home and field sites without exposure. We build zero-trust access aligned to EO 14028 and OMB M-22-09.
Budget & procurement pressure
Continuing resolutions and fiscal-year deadlines make planning brutal. Flat-rate, GSA-friendly managed services give your CFO and CIO a predictable cost model.
End-to-end government IT, one accountable partner
Managed IT, cybersecurity, government cloud, and compliance support for federal, state, and local teams.
Help desk & monitoring
US-based help desk that understands mission urgency, with endpoint monitoring, patch management aligned to maintenance windows, and SLA-backed response.
Managed cybersecurity
SOC-monitored EDR/XDR with CISA-aligned detection, email and phishing defense, PIV/CAC plus MFA everywhere, and continuous monitoring per NIST 800-137.
Government software support
Expert configuration of M365 GCC High, Google Workspace for Government, ServiceNow, Tyler Technologies, Granicus, OpenGov, Accela, and CivicPlus.
Cloud migration & hosting
Azure Government and AWS GovCloud landing zones, DoD IL2 through IL5 architecture, StateRAMP-aligned hosting, and immutable encrypted backups.
Secure email & records
Hardened M365 GCC High and Google Workspace Gov, encrypted email and DLP for CUI, plus FOIA-ready archiving aligned to NARA and records schedules.
Compliance & ATO support
NIST 800-53 and 800-171 control mapping, FedRAMP Moderate and High packages, CMMC 2.0 readiness, CJIS, and POA&M, SSP, and continuous-monitoring documentation.
Why government cybersecurity is different
Public-sector security is not just good practice, it is a statutory and mission-critical mandate.
FISMA & FedRAMP are statutory duties
Federal systems must be safeguarded under FISMA using NIST 800-53 controls, and cloud services must be FedRAMP authorized. A lapse can trigger OIG findings and ATO revocation. We build to these standards from day one.
Government is a top nation-state target
Agencies and contractors are continuously targeted for the sensitive data and leverage they hold. Threat actors study agency workflows and supply chains, so our defensive stack is built for how you are actually attacked.
CMMC, CJIS & sector mandates
DoD contractors must reach CMMC 2.0 certification, law enforcement must meet the CJIS Security Policy, and healthcare-adjacent agencies must meet HIPAA. We deliver the exact control set each authority demands.
Executive orders & OMB mandates
EO 14028, OMB M-22-09 zero trust, and CISA directives flow constantly. We track and implement the controls each new directive requires so you stay ahead of audits.
