Identity is the new perimeter. In an organization that serves healthcare systems, government agencies, AI platforms, and research institutions — across time zones, languages, and classification levels — the question is never "are you on the network?" The question is: "who are you, what do you need, and can we verify both right now?"
Ariana Nexus governs access to every system, dataset, and application through a centralized identity framework. No access is inherited. No access is permanent. No access is assumed. Every identity — whether an employee in Arlington, a guest collaborator in London, or a future Human Intelligence Collective interpreter in Sacramento — is authenticated, authorized, scoped, and monitored through a single, auditable control plane.
Ariana Nexus manages identities across their full lifecycle — from provisioning through active use to deprovisioning — ensuring that access rights reflect current roles, not historical accumulation.
Provisioning: When a new identity is created (employee, guest, or service account), it is assigned a role with predefined permissions based on job function. No identity is provisioned with administrative or elevated access by default. All provisioning decisions are documented and approved by an authorized administrator.
Active Management: During the active lifecycle, identities are subject to continuous policy enforcement — MFA at every sign-in, Conditional Access evaluation at every session, and compliance verification at every device. Access rights are reviewed periodically to ensure alignment with current responsibilities.
Modification: When an individual's role changes — promotion, lateral move, project reassignment — their access rights are updated to reflect the new role. Prior permissions that are no longer required are revoked. This prevents privilege creep, one of the most common and exploitable security gaps in organizational environments.
Deprovisioning: When an individual leaves the organization or an engagement ends, their identity is disabled within twenty-four (24) hours. All active sessions are terminated. Device access is revoked. SharePoint and Teams permissions are removed. For guest identities, access expiration is enforced automatically based on the engagement timeline.
Audit: Every provisioning, modification, and deprovisioning event is logged in Microsoft Entra ID audit logs with timestamps, the administrator who performed the action, and the specific changes made. These logs are retained in accordance with Ariana Nexus's data retention policies and are available for compliance reporting and incident investigation.
Ariana Nexus operates a tiered identity model that separates access rights by function, sensitivity, and trust level. This ensures that every individual has exactly the access required for their role — no more, no less.
Administrative identities have elevated privileges over the Microsoft 365 environment, including the ability to manage users, configure security policies, and access audit logs. Due to the sensitivity of these privileges:
Standard employee identities represent the core workforce of Ariana Nexus — full-time employees who access Microsoft 365 services (Exchange, SharePoint, Teams, OneDrive) for daily operations.
Ariana Nexus collaborates with clients, institutional partners, and external advisors through Microsoft Entra External Identities (B2B guest access). Guest identities are subject to the following controls:
As the Human Intelligence Collective scales — incorporating interpreters, translators, subject-matter experts, and independent contractors — Ariana Nexus will provision a dedicated identity tier with the following characteristics:
Target deployment: Q4 2026 – Q1 2027, aligned with the hiring plan for 50+ interpreters and 10 project managers outlined in the Ariana Nexus growth strategy.
All identity and access governance at Ariana Nexus is centralized in Microsoft Entra ID (formerly Azure Active Directory), the cloud-native identity platform included in Microsoft 365 Business Premium. Entra ID serves as the single source of truth for all authentication, authorization, and access policy enforcement.
MFA is enforced for 100% of identities — employees, administrators, and guests — with no exceptions and no bypass paths.
Supported MFA methods:
Enforcement scope:
Conditional Access policies are the policy engine that enforces Zero Trust access decisions at every session. Ariana Nexus has deployed the following Conditional Access policies:
Ariana Nexus implements RBAC through Microsoft Entra ID roles and Security Groups:
Ariana Nexus conducts periodic access reviews to ensure that permissions remain aligned with current roles:
Ariana Nexus enforces the following password standards, aligned with NIST SP 800-63B Digital Identity Guidelines:
Ariana Nexus is evaluating the transition to passwordless authentication methods, which eliminate the primary attack vector (password compromise) entirely:
NIST SP 800-207 (Zero Trust) — Identity as the primary security perimeter. Status: Implemented — Entra ID as central identity plane.
NIST SP 800-63B (Digital Identity) — Authentication assurance levels, password guidance. Status: Aligned — MFA enforced, NIST password policy adopted.
NIST SP 800-171 Rev. 2 / Rev. 3 — Access Control family (AC-1 through AC-22). Status: Aligned — RBAC, MFA, least privilege enforced; formal SSP in development (Rev. 2 current for DoD/CMMC; Rev. 3 transition planned per DoD rulemaking).
HIPAA Security Rule (45 CFR § 164.312) — Access controls, unique user identification, automatic logoff, encryption. Status: Aligned — MFA, unique identities, session controls, Purview encryption.
CJIS Security Policy — Advanced authentication for CUI access. Status: Roadmap — MFA satisfies requirement; formal CJIS assessment planned (2027).
CMMC Level 2 — Access Control (AC), Identification & Authentication (IA) domains. Status: Roadmap (2027) — Controls implemented, certification planned.
ISO 27001:2022 — Annex A.9 — Access Control. Status: Roadmap (2027) — Controls aligned, formal certification planned.
SOC 2 (Trust Services Criteria) — CC6 — Logical and Physical Access Controls. Status: Roadmap (2026–2027) — Controls operational, audit engagement planned.
EU AI Act — Access controls for high-risk AI system data. Status: Aligned — RBAC governs AI Data Factory access.
GDPR / UK GDPR — Article 32 — Security of processing. Status: Aligned — MFA, access controls, audit logging implemented.
When Ariana Nexus engages in work involving Protected Health Information, identity governance ensures that only credentialed personnel — authenticated through MFA, operating on compliant devices, and assigned to the specific engagement — can access PHI. SharePoint sites containing PHI are isolated with dedicated Security Groups. Guest access to PHI environments requires an executed Business Associate Agreement and sponsor approval. Audit logs capture every access event for HIPAA compliance reporting.
For government engagements involving Controlled Unclassified Information, identity governance implements the Access Control (AC) and Identification and Authentication (IA) families of NIST SP 800-171. CUI environments are segregated in dedicated SharePoint site collections with restricted Security Groups. Access is limited to U.S.-based personnel with verified need-to-know. Guest access to CUI environments is prohibited unless explicitly authorized by the government contracting authority.
The AI Data Factory processes linguistic, cultural, and annotation data for AI model training and validation. Identity governance ensures that HITL reviewers, annotators, and quality assurance personnel are authenticated individually, their access is scoped to only the datasets and pipelines assigned to their task, and their sessions are logged for data provenance and audit trail purposes.
Academic collaborations involving sensitive research data are governed through time-bound guest identities with MFA enforcement, scoped access to designated SharePoint libraries, and automatic deprovisioning upon project completion.
For procurement officers: Ariana Nexus can demonstrate, through Entra ID audit logs and Conditional Access reports, exactly who accessed your data, when, from where, on what device, and under what policy conditions.
For CISOs: Our identity architecture is built on Microsoft Entra ID — a Gartner Magic Quadrant Leader in Access Management — with native integration across MFA, Conditional Access, device compliance, and DLP. There are no gaps between identity verification and data protection.
For compliance officers: Our RBAC model, access review cadence, and audit logging satisfy the access control requirements of HIPAA, NIST SP 800-171, SOC 2, and ISO 27001. We can produce access reports on demand for your audit teams.
For government contracting officers: Our identity governance separates CUI-accessible identities from general employee identities, enforces MFA at the authentication assurance level required by NIST SP 800-171 and CJIS, and maintains audit trails that satisfy DFARS 252.204-7012 reporting requirements.

No Guarantee of Unauthorized Access Prevention. Ariana Nexus implements commercially reasonable identity and access controls aligned with recognized industry frameworks. However, no identity governance system can guarantee absolute prevention of unauthorized access. Ariana Nexus expressly disclaims any warranty or guarantee that its identity systems will prevent all unauthorized access, credential compromise, or identity-based attacks.
Framework Alignment vs. Certification. Where this page states that Ariana Nexus is "aligned" with a framework, this means controls are designed in accordance with the framework's principles but formal third-party certification has not been obtained unless explicitly stated. Alignment is not certification.
