Role Design & Access Modeling
We work with your business and IT teams to map job functions to access requirements, identify role conflicts and segregation of duties violations, and design a role model that reflects how your organization actually works: not an idealized org chart.
Access Review & Entitlement Cleanup
Most organizations starting RBAC have years of accumulated over-privilege: previous roles, departures never deprovisioned, shared accounts no one owns. We run a structured access review and clean up the entitlement landscape before implementing new controls.
Segregation of Duties (SoD) Controls
We identify SoD conflicts in your current access model and implement controls that prevent the combinations most relevant to your risk profile and compliance requirements: preventing any single user from holding conflicting permissions.
RBAC in Active Directory & Cloud Directories
We implement RBAC across Active Directory, Microsoft Entra ID, AWS IAM, and GCP. Role assignments are managed centrally and enforced consistently whether users are accessing on-premises systems or cloud resources.
Automated Access Reviews & Certification
We implement automated access certification workflows: using SailPoint, Saviynt, or built-in platform capabilities: so managers review and approve access regularly without IT involvement for every case.
RBAC Documentation for Compliance
We deliver a complete RBAC framework document: role definitions, access matrices, SoD policy, and review procedures: that satisfies SOC 2, HIPAA, ISO 27001, and PCI DSS auditor requirements.
Understanding RBAC
What organizations need to know about role-based access control
What is RBAC?
Role-Based Access Control is an access management approach where permissions are assigned to roles rather than to individual users. Each user is assigned one or more roles based on their job function, and inherits the permissions defined for those roles. This replaces ad hoc, user-specific permission grants with a structured model that is consistent, auditable, and manageable at scale.
Who needs it?
RBAC is essential for any organization with more than a small team and more than a handful of systems. It becomes critical when compliance frameworks require demonstrable least-privilege access, SOC 2, HIPAA, PCI DSS, ISO 27001, and CMMC all audit whether users have only the access their role requires. It also matters operationally: without roles, onboarding and offboarding require manual access decisions for every person.
Why does it matter?
Over-privileged accounts are the most commonly exploited condition after credential theft. When an attacker compromises a standard user account that has accumulated admin-level permissions over time, they have everything they need. RBAC enforces least privilege by design, users get only what their role requires, excess permissions are removed, and access automatically reflects role changes rather than accumulating indefinitely.
How is RBAC implemented?
Implementation starts with role design, mapping your org structure to a role model that reflects actual job functions. Existing entitlements are reviewed and cleaned up, excess permissions removed. Roles are built in Active Directory, Entra ID, or your cloud directories. Segregation of Duties controls prevent policy-violating role combinations. Automated access review processes run on a schedule to catch drift before the next audit.
What Makes Us Different From Others
- Business Process-Driven Role Design We start with job functions and work backward to access requirements. Roles reflect how people actually work, not Active Directory groups.
- SoD Conflict Detection Included Every RBAC engagement includes a segregation of duties analysis before new roles are deployed.
- Entitlement Cleanup Before Rollout We clean up the access landscape before implementing new controls. Starting RBAC on top of years of over-privilege produces poor results.
- Compliance-Mapped Role Matrix Every role definition maps to specific compliance requirements. Auditors see exactly which roles satisfy which controls.
- Ongoing Governance Built In We build the process for ongoing access certification and role management: RBAC requires governance to stay effective over time.
We had over 200 contractor accounts in Active Directory that nobody owned. garrisonOne mapped every identity, implemented PAM controls for privileged accounts, and set up automated provisioning and deprovisioning tied to our HR system. First audit after rollout, the finding list was empty.

Frequently asked questions
What is role-based access control (RBAC)?
RBAC is an access control model where permissions are assigned to roles, and roles are assigned to users based on job function. Users inherit the permissions of their role rather than having permissions assigned individually, making access management scalable and auditable.
What is the difference between RBAC and ABAC?
RBAC assigns access based on static roles tied to job function. ABAC evaluates dynamic attributes at access time: user department, device type, time of day, data classification. RBAC is simpler to implement and audit. Most organizations use RBAC as a foundation with ABAC-style conditional access for sensitive resources.
What is segregation of duties and why does it matter?
Segregation of duties prevents any single user from having the combined access needed to complete a high-risk transaction without oversight. SoD violations are a leading cause of financial fraud and are specifically required by PCI DSS, SOX, and ISO 27001.
Is RBAC required for compliance?
Access control requirements in SOC 2 (CC6.1, CC6.3), HIPAA, PCI DSS (Requirements 7 and 8), and ISO 27001 (A.9) all require documented, enforced access controls based on least privilege. RBAC is the standard implementation approach.
How long does an RBAC implementation take?
A focused RBAC implementation for a mid-size organization typically takes six to twelve weeks including access review, role design, implementation, and documentation.
What happens to existing access during an RBAC rollout?
Existing access is reviewed and right-sized. Users with more access than their role requires have excess permissions removed. Users lacking access required for their role have it added. The goal is every user with exactly the access their job requires: no more, no less.
