Atom Cybersecurity — two practices, one standard
The platforms we deploy in compliant environments

The tools that live inside the boundary.

Handling CUI or ITAR-controlled data narrows the field: the platform has to run in a Government, GovCloud, or FedRAMP-authorized edition, keep support and data on US soil, and produce the evidence a Level 2 assessment expects. These are the ones we deploy, operate, and map to the NIST SP 800-171 control families for the Defense Industrial Base.

Read this first

The edition matters as much as the brand.

A tool that is perfectly compliant in a commercial tenant can be the wrong choice for CUI. What matters is the specific edition and deployment — the Government or GovCloud SKU, the FedRAMP authorization level, where support staff sit, and where data comes to rest. We deploy and operate each platform below in the configuration that fits a controlled environment, and generate the artifacts your assessor will ask for.

One line of scope: Atom is a managed security and compliance provider, not a C3PAO. We deploy and run these platforms and prepare you for assessment — we do not perform the official certification.

Verify before you rely — FedRAMP levels, GovCloud availability, and CUI-environment suitability change over time. Confirm the current authorization and deployment guidance against each vendor's documentation and your specific contract requirements before scoping.

01 Managed EDR / XDR Endpoint / XDR

Our managed endpoint detection & response (EDR/XDR) platform is the backbone of our detection and response practice — a single cloud-native sensor covering EDR/XDR, next-gen AV, and identity protection, backed by analyst-led managed detection. For defense work, we offer a government/FedRAMP-authorized EDR/XDR deployment and GovCloud deployment options intended for regulated and CUI-bearing environments, keeping the telemetry pipeline inside a boundary you can reason about.

  • Full EDR/XDR suite — EDR/XDR, NGAV, and identity protection under one sensor
  • Government / FedRAMP-authorized deployment / GovCloud options for CUI-bearing environments
  • Retained detection and containment records for Audit & Accountability
  • Incident detection and response workflow for Incident Response
  • Malicious-code defense for System & Information Integrity
02 Zero-Trust Identity & MFA Identity / MFA

With the network perimeter gone, identity is the control plane. Our platform enforces zero-trust multi-factor authentication and device trust, so reaching CUI depends on a verified user and a healthy, known device. Critically for CMMC, it supports phishing-resistant MFA methods, and offers a FedRAMP-authorized MFA deployment aligned to FedRAMP-authorized deployments where the contract requires it.

  • Phishing-resistant MFA — the method that actually withstands modern credential attacks
  • FedRAMP-authorized MFA deployment — for government-facing deployments
  • Device trust and adaptive, per-application access policies
  • Serves Access Control and Identification & Authentication
  • Every authentication decision logged for assessment evidence
03 Enterprise Email Security Email Security

Email is where most intrusions begin, so we anchor the inbox with an enterprise secure email gateway providing threat protection, data loss prevention, and archiving. For the defense side, it offers government and GovCloud deployment options that keep threat processing and archived mail inside US-based, compliance-oriented infrastructure — the monitored, boundary-protected communications an assessor expects.

  • Threat protection, DLP, and archiving for the primary attack surface
  • Government / GovCloud deployment options for regulated environments
  • Boundary and communications protection for System & Communications Protection
  • Outbound DLP controls over what leaves the CUI boundary by mail
  • Retained verdicts and quarantine logs as evidence the control operates
04 AI Email Detection & Response Email Detection & Response

Where a signature-based gateway relies on known-bad, our AI-native email detection & response is AI-native and API-based — it reasons about message intent, tone, and sender behavior to catch business email compromise and novel phishing that slips past legacy filters. Because it connects by API, it deploys alongside your existing mail environment (for example, Microsoft 365 GCC High) rather than sitting inline, so it strengthens detection without re-routing controlled mail flow.

  • AI-native, behavioral detection — catches BEC and never-before-seen phishing
  • API-based deployment alongside the mail environment (e.g., M365 GCC High)
  • Programmable detections tuned to the lures targeting your people
  • Content and phishing detection for System & Information Integrity
  • Automated quarantine and clawback across mailboxes, with retained verdicts
05 Email, Backup & Network Protection Email & Network

This layer gives us broad protection spanning email security, backup, and network defense — gateway filtering for spam and malware, cloud-to-cloud backup for Microsoft 365, and firewall options at the network edge. In a controlled environment it contributes both boundary protection and a recoverable copy of mail-resident data, with US-based deployment options where residency is in scope.

  • Email protection — spam, malware, and phishing filtering at the gateway
  • Cloud-to-cloud backup — recoverable copy of Microsoft 365 mail data
  • Network security — firewall options for perimeter and public apps
  • Boundary protection for System & Communications Protection
  • Protected backup of mail-resident CUI for Media Protection
06 Backup & Continuity (BCDR) Backup / BCDR

Detection is only half the job — recovery is the other half, and for a defense contractor it is a control obligation. Our image-based backup & business continuity (BCDR) delivers image-based business continuity with rapid failover plus SaaS backup for Microsoft 365. When CUI is in play, data residency and US-based recovery matter as much as the RPO: we configure the backup estate so controlled data stays where the contract requires and restores can be proven, not promised.

  • Image-based BCDR — instant local restore and rapid failover
  • SaaS backup — protection for Microsoft 365 and cloud-resident CUI
  • Data residency — US-based recovery aligned to contract requirements
  • Protected, access-controlled backup media for Media Protection
  • Tested restores with documented RPO / RTO for Contingency / Recovery
07 Security Awareness Training Security Awareness

The strongest stack still has to survive human error, and people are a control family in their own right. Our security awareness training & phishing simulation runs continuous phishing simulation and role-based training so your workforce learns to recognize the social engineering no gateway fully stops — and, just as important, produces the per-user completion and click-rate records that make the training defensible on assessment day.

  • Phishing simulation — safe, realistic tests of your workforce
  • Role-based training — security and CUI-handling modules per role
  • Insider-threat recognition and reporting awareness
  • Directly serves the Awareness & Training family
  • Per-user completion and click-rate records as defensible evidence
08 AI-Driven vCISO Platform vCISO Platform

Our AI-driven vCISO & governance platform is the engine behind our vCISO practice. It runs automated assessments against NIST SP 800-171, generates and maintains the System Security Plan (SSP) and Plan of Action & Milestones (POA&M), builds prioritized remediation roadmaps, and produces board- and prime-facing reporting. It is the governance layer that turns the tools above into a documented program — the work that satisfies the DFARS clauses your contracts flow down.

  • Automated NIST SP 800-171 assessments across all 110 controls
  • SSP & POA&M generation — authored and kept current
  • Roadmaps & board reporting — prioritized, prime-ready posture
  • DFARS 252.204-7012 DFARS 252.204-7021
09 Microsoft GCC High Compliance Enclave

Every platform above operates within a boundary — and for CUI and ITAR/export-controlled data, that boundary is most often Microsoft GCC High. It is the de-facto compliant enclave for the Defense Industrial Base: US-sovereign infrastructure with US-person support, built to hold controlled information in one authorized place. Get the enclave right and the rest of your program becomes tractable — a tight boundary means fewer systems to prove on assessment day.

  • The CUI / ITAR boundary — the authorized home for controlled and export-controlled data
  • US-sovereign, US-person support — residency and access that ITAR demands
  • The environment the other platforms operate inside — not a competing tool
  • Anchors the overall CUI boundary and Access Control
  • A defined boundary shrinks assessment scope and the controls you must defend
10 Microsoft 365 ITDR Identity Threat Detection & Response

With the perimeter gone, a stolen identity is often the whole intrusion — so we monitor the identity layer directly. Our identity threat detection & response continuously watches Microsoft 365 and Entra ID for account takeover, business email compromise, and token/session theft, and contains attacks automatically by killing malicious inbox rules and rogue OAuth grants. It runs alongside your existing Microsoft 365 environment (e.g., GCC High) and retains forensics across Entra ID, Exchange, and SharePoint as the evidence an assessor expects.

  • Account takeover, BEC, and token-theft detection in Microsoft 365 and Entra ID
  • Automatic containment of malicious inbox rules, rogue OAuth grants, and compromised auth methods
  • Verified identity and access enforcement for Identification & Authentication and Access Control
  • Detection and automated response workflow for Incident Response
  • Malicious-activity monitoring and retained forensics for System & Information Integrity
Not sure what your scope needs?

The right editions, in the right boundary — not one of everything.

Few contractors need every platform on this page on day one. In a readiness assessment we map these tools against your CUI scope, existing Microsoft licensing, and the control families your contract flows down, then recommend the compliant mix that closes the widest gaps first.

A reminder: confirm current FedRAMP / GovCloud authorization levels and CUI-environment suitability against each vendor's documentation and your specific contract before you commit to a design.
