AI governance for government agencies and defense contractors.
Every AI interaction in government and defense environments touches data that demands the highest level of protection — CUI, export-controlled technical data, classified information, and federal records. Arbitex puts a governance layer in front of every AI call, enforcing compliance policies and producing tamper-evident audit records before any data reaches a model endpoint.
Capabilities
AI governance built for federal and defense environments.
DLP for CUI and PII
Controlled Unclassified Information and personally identifiable information flowing through AI-assisted workflows represent the highest-risk data categories in government and defense environments. Arbitex's 3-tier DLP pipeline inspects natural-language AI prompts before any model processes the request. ML-based entity recognition identifies personal and credential data expressed as prose rather than structured fields, and the AI-powered contextual validator reduces false positives in professional government and defense language. Arbitex does not ship CUI-category detectors: agencies author org DLP rules for the CUI markings and controlled identifiers in scope, and every detection is recorded with its rule reference for audit trail completeness.
Air-Gap Outpost for Classified Networks
SCIFs, classified defense networks, and air-gapped government environments cannot route AI traffic through cloud infrastructure. Arbitex's Hybrid Outpost deploys the full governance data plane inside the customer's isolated environment — DLP inspection, policy enforcement, and audit logging execute entirely within the air-gapped perimeter. cryptographically signed rule bundle updates fail-closed, the local audit queue accumulates governance events and syncs on reconnection, and optimized offline models run deterministic inference without any cloud dependency. The same detection accuracy applies in air-gap as in cloud deployment.
NIST Policy Packs
NIST SP 800-53 and NIST SP 800-171 define the security control baseline for federal information systems and CUI protection in nonfederal organizations. The controls Arbitex provides — access control over who can reach which models, a tamper-evident audit record, and in-path enforcement — are technical building blocks that several NIST control families call for, including Access Control (AC), Audit and Accountability (AU), Identification and Authentication (IA), and System and Communications Protection (SC). Arbitex does not ship NIST 800-53 or 800-171 policy packs; your compliance team maps the audit evidence to the control set when producing system security plan artifacts.
FISMA Audit Trails
FISMA requires federal agencies and their contractors to maintain continuous monitoring and audit capabilities across information systems processing federal data. Arbitex produces tamper-proof, tamper-evident audit records for every AI governance decision — which request contained sensitive data, which DLP tier flagged it, which compliance rule applied, what enforcement action executed, and a cryptographic integrity chain demonstrating the record has not been modified since creation. These records map directly to FISMA audit and accountability requirements and support IG investigations, ATO evidence packages, and continuous monitoring program reporting.
GeoIP for Data Sovereignty
Government agencies and defense contractors operate under data sovereignty requirements that restrict where federal data can be processed and by which geographic entities. Arbitex enriches every AI request with GeoIP metadata — country, region, ASN, and anonymous IP detection (VPN, proxy, Tor, hosting provider) — enabling policy rules that enforce geographic access restrictions at the AI model boundary. Requests originating from unauthorized jurisdictions or anonymized network paths are blocked before reaching any model endpoint. The bundled offline GeoIP database supports Hybrid Outpost deployments where external lookups are not permitted.
Credential Intelligence for Insider Threat
Insider threat programs in government and defense environments must detect compromised credentials and unauthorized access attempts across all information systems — including AI-assisted workflows. Arbitex checks every AI request against a compromised credential dataset at sub-millisecond latency, flagging leaked API keys, compromised credential dataset matches, and known-compromised bearer tokens before they propagate through AI pipelines. Combined with behavioral pattern detection — bulk extraction of classified content, repeated queries about controlled technical data, and exfiltration-pattern prompts — the credential intelligence layer provides continuous monitoring evidence for insider threat programs required under Executive Order 13587 and NISPOM.
How it works
Classify AI data against government and defense categories
Arbitex's 3-tier DLP pipeline inspects every AI request in-path before any model processes it — 80+ pattern rules at Tier 1, 40 ML-based entity recognition detectors at Tier 2, and AI-powered contextual validation at Tier 3. The shipped detectors cover PII, credentials, and regulated financial and healthcare data; CUI markings, classified data markers, and export control classifications are covered by org DLP rules your team authors, which run through the same three tiers.
Enforce security policies per framework and classification
Pre-built compliance bundles cover the marketed regulatory and AI-governance frameworks, and custom org rules cover the government-specific data types they do not. The policy engine evaluates conditions — DLP detection results, user identity, organization, geographic origin, and content classification — and applies enforcement actions: block, redact, route to an authorized model, or escalate for review. All bundles run simultaneously under a single policy configuration without per-framework deployment.
Deploy in air-gap or hybrid configuration
The Hybrid Outpost deploys the full governance data plane inside your authorized boundary — on-premises, in your agency VPC, or in an air-gapped classified network. DLP inspection, policy enforcement, and audit logging execute entirely within your perimeter. Optimized offline models provide the same detection accuracy without cloud connectivity. cryptographically signed rule bundles and local audit queues support disconnected operation with fail-closed security posture.
Seven frameworks. One policy layer.
Each compliance obligation maps to a specific Arbitex capability. All bundles are active simultaneously — no separate configuration per framework or authorization level.
Cloud service authorization framework for federal agencies. Arbitex's hybrid deployment model supports FedRAMP authorization requirements — the data plane deploys inside the agency boundary while maintaining the security controls required for authorization at Moderate and High impact levels.
Continuous monitoring, risk management, and audit requirements for federal information systems. tamper-proof audit records provide the tamper-evident governance evidence required for FISMA continuous monitoring programs and IG audit responses.
The comprehensive control catalog for federal information systems. Arbitex enforcement maps to AC, AU, CM, IA, IR, and SC control families — providing technical implementation evidence for the controls that govern AI data flows in federal environments.
CUI protection requirements facing the defense industrial base. Arbitex does not ship a CMMC bundle; its tamper-evident audit logs give compliance teams the AI-usage evidence they carry into DIBCAC assessments and prime contractor compliance reviews.
Governs export-controlled defense articles and technical data on the USML. Arbitex does not ship ITAR detectors; agencies and contractors author org DLP rules for the USML identifiers in scope, which run through all three inspection tiers before any prompt reaches a model.
Dual-use technology controls under the Commerce Control List. Arbitex does not ship ECCN detectors; ECCN patterns are authored as org DLP rules, and the policy engine applies jurisdictional routing and enforcement to AI-assisted engineering and procurement workflows.
DoD contractual requirement for protecting covered defense information in contractor systems. Arbitex provides AI-boundary technical controls — inspection, enforcement, and tamper-evident audit evidence — that support the incident reporting and documentation obligations under the clause.
