1. Zen IT Technologies
  2. Identity & Access Management

One source of truth for who can reach what.

Identity is the control plane. When it is fragmented across three directories, a spreadsheet, and whoever remembers to remove access on someone's last day, every access control around it becomes harder to reason about and verify.

We design the identity architecture, migrate the platform where that is the right answer, federate the applications that matter, and automate provisioning end to end. One source of truth is not one vendor. It means each part of the identity lifecycle has a clear authority, and downstream access follows that model.

Let's talk

The problem

Most identity estates were never designed. They accumulated.

A directory chosen in year one. A second one added when the first could not manage Macs. SSO on the six applications someone got around to, and local passwords on the forty that followed. Offboarding that depends on a checklist someone maintains manually.

The symptoms are recognizable:

  • Accounts that outlive employment.

    Departed users still holding active sessions in SaaS applications nobody inventoried.

  • Manual provisioning at scale.

    New hires waiting a day for access, and IT hand-creating accounts in a dozen systems.

  • Standing privileged access.

    Admin rights granted for a project three years ago and never revoked.

  • More than one source of authority.

    Two of them both believe they own identity, and reconciliation happens by eye.

  • Audit questions you cannot answer.

    An auditor asks who had access to what, and when, with no system able to answer.

What identity and access management covers

Identity sources

  • HR / HRIS employment state and attributes
  • Directory / AD / LDAP directory identity, synchronized where applicable

Identity control plane

IdP

Access and enforcement

  • Applications / SaaS SAML and OIDC federation, SCIM provisioning, groups and attributes mapped to application roles
  • Cloud & infrastructure federation, and groups mapped to IAM roles and entitlements
  • Network access VPN, ZTNA and Wi-Fi authentication through a RADIUS or equivalent identity integration
  • Endpoint / MDM user context out device posture and trust in

Security telemetry

  • EDR / XDR detections and device risk
SIEM / security data lake identity, application, cloud, network, endpoint and EDR/XDR telemetry

Identity architecture and platform selection

  • Identity architecture and platform selection

    Most platform comparisons are answered at the wrong level. Single sign-on is a capability, not a product category competing with an identity provider. The question is how much identity architecture the organization needs: centralized sign-in and consistent MFA answer some environments completely, while others need the lifecycle and governance built around them. Paying for the second when you need the first buys capability you will not configure.

    Running more than one platform can be entirely correct. Device management, directory services and application access have different requirements, and the best tool for each is not always the same vendor. What cannot be split is authority: one platform is authoritative for downstream identity and access state, even when employment status originates in HR, and the others consume from it.

    Sometimes the current platform is fine and the problem is how it is configured. Which controls and signals exist at all depends on the platform, its licensed edition, the endpoint architecture and the application being protected, so we establish those requirements before recommending a platform or an upgrade.

  • Authentication, MFA and passwordless access

    Authentication is where account compromise is either stopped or not. We design the model around it: which factors are accepted and how enrollment and recovery work without becoming the weakest step in the chain.

    Phishing-resistant methods bind the credential to the device, so there is no code for someone to relay to an attacker who asked for it. The person verifies locally with a fingerprint, face or device PIN depending on the hardware, and the credential itself stays on the device. Okta FastPass, JumpCloud Go and standards-based passkeys are examples of how this is delivered.

    Moving routine sign-in away from reusable passwords removes one of the easiest credentials to phish, reuse and automate against. That reduces the attack surface rather than closing it, so the paths that remain, including recovery flows, legacy protocols and service accounts, are dealt with deliberately.

  • SSO and application federation

    SAML and OIDC integration across your SaaS estate, including the awkward ones: custom authorization servers, API scope design, applications with partial standards support, and platforms requiring bespoke claim mapping.

    The design decides what each application trusts from the identity provider: which claims and groups it receives, and how those map to roles inside it. Applications that cannot federate get an alternative path rather than being left outside the model.

    We prioritize by risk rather than by ease, so the systems holding your source code, customer data, and money get federated first.

  • Provisioning, attributes and lifecycle

    Automated joiner, mover and leaver flows driven from your HR system through identity into downstream applications. Access is granted by role on day one. At termination it is withdrawn automatically wherever the application's lifecycle support allows. Identity and application controls are used to revoke active sessions where that is supported, and anything that cannot be automated is named and reviewed rather than forgotten.

    Role-derived access only works if the data model underneath it does. We design the authoritative attributes, the profile mappings between systems, the group rules that read them, and the application and license assignments those groups drive. A change in the HR system then propagates on its own, every entitlement has a written rule behind it rather than a memory of why someone was added, and the reporting shows that the lifecycle actually ran.

  • Conditional access and authentication policy

    Not every request deserves the same treatment. Access policy reads the context around a sign-in: who the user is and what role they hold, which application they are reaching and how sensitive it is, whether the device is known and managed, how strongly they authenticated, and where the request came from.

    Where the platform supports it, a sensitive system can require a managed device and a stronger method, while a request from an unknown device or an unexpected context is challenged or refused. Location is a signal rather than a fact, because IP geolocation is approximate: access from regions where the company does not operate can be restricted, and unusual geography can raise the bar rather than decide on its own.

    The aim is that normal access gets easier and abnormal access gets harder.

  • Access review and privileged access governance

    Point-in-time reviews of who holds what, including the grants that never went through a process. We map every entitlement, identify standing privilege, design a group model that replaces individual assignment, and establish a review cadence your leadership can own. The same design has to preserve tightly controlled emergency access, so that a policy or platform failure cannot lock the organization out of its own environment.

    The output is structured for audit: an entitlement inventory, a remediation log, and a documented process.

  • Vendor Review and Vendor Management

    New platforms should not gain access to company data simply because somebody needs the product. We review what the platform needs to access, through which integrations or API scopes, how it authenticates, what data it handles, which users or groups require it, and whether its security and compliance posture is appropriate for that scope.

    Approval is only the beginning. We define the access that is allowed, the restrictions that apply, who owns the platform, who holds administrative access and how service accounts are governed, how users are provisioned and removed, and when that access needs to be reviewed again. Changes in integrations, permissions, licensing or business use are reassessed rather than inheriting the original approval indefinitely.

Migration and consolidation

Full migrations between identity platforms: JumpCloud to Okta, Google or an on-premises directory to Entra ID, and the consolidation of parallel directories behind one authoritative source. Planned as a sequenced cutover with validation gates and a defined rollback or recovery path at each stage, not a weekend gamble. The steps that cannot be reversed are identified before they are crossed.

We handle the parts that break: password and session continuity, device-object reconciliation, group model translation, and the applications whose federation config nobody documented.

The lifecycle crosses the whole company

Onboarding, a role change and an offboarding are not IT events. They begin in People or HR, touch Operations and Finance, wait on a manager's approval, and end in a dozen applications with different owners. Identity is where those steps meet, which is why the process around it matters as much as the platform.

The capability has a name, IT Workflow & Process Automation, and in practice it means deciding what IT should own, automating what should not be manual, and writing down where each handoff sits so nothing waits on somebody remembering.

How it runs

  1. Discovery.

    A documented inventory of directories, applications, entitlements, and device objects. You find out what you actually have, which is usually more than expected.

  2. Design.

    Target-state architecture: authoritative source, group model, federation priority order, and provisioning flows. Written, reviewed, and agreed before anything moves.

  3. Implementation.

    Federation, provisioning, groups and access policy are implemented in controlled stages on a new or existing platform. Where migration is part of the design, applications move in sequence rather than in one cutover.

  4. Governance.

    The review cadence, runbooks, and reporting are handed to your team, or managed with you, depending on the engagement.

Proof

  • Identity and device management separated without a disruptive migration.

    Cybersecurity company

    Authentication and endpoint management had become tightly coupled to a single platform. The architecture was separated so identity could move to a modern provider while the existing device-management estate continued operating throughout the transition.

  • Standing access replaced with role-driven control.

    Fintech

    Access mapped across a complex SaaS environment, individual grants replaced with role-derived groups, and a repeatable review process handed to the internal team.

  • An application without enterprise identity support brought under central authentication.

    Technology company

    A platform that could not meet the required identity model was integrated through an alternative architecture, bringing authentication and user lifecycle control back under the organization's central identity environment.

  • A fragmented access model replaced with lifecycle-driven access.

    Technology company

    Applications moved to role and group-derived access with automated provisioning and centralized authentication. Standing access was reduced, and onboarding and offboarding became predictable rather than manual.

Client examples are anonymized by design. References are provided privately, on request, and with the client's consent.

Who this is for

This is usually the point to act when:

Your headcount and SaaS estate are growing faster than the identity model behind them.

More than one system can grant access, but nobody can clearly say which one is authoritative.

An audit or customer security review is asking questions your current process cannot answer cleanly.

Migration is a project. Identity is ongoing. We work embedded with your team because identity is the layer the rest of your environment depends on.

Frequently asked questions

  • Do we need an identity provider, or is SSO enough?

    Those are not two competing products. Single sign-on is a capability, and the question is how much architecture you need around it. If centralized sign-in and consistent MFA cover the requirement, that is a complete answer; if the lifecycle has to be governed, the architecture is larger.

  • Is it a problem to run more than one identity platform?

    Not necessarily, and it is often the right architecture. What cannot be split is authority: one platform has to be authoritative for downstream identity and access state, and the others consume from it rather than keeping an independent lifecycle.

  • How long does a platform migration take?

    Weeks rather than days, driven by the number of federated applications and the complexity of the group model rather than by the platform itself. Both platforms usually run in parallel with one authoritative source during the transition, which adds temporary license cost and removes the single cutover date everyone is afraid of.

  • Do we need to replace our current identity platform?

    Often not. If the platform already supports the federation, provisioning and policy your design calls for, the work is configuration rather than replacement, and we will say so. Replacement earns its cost when the architecture you need is something the current platform cannot express.

  • What is SCIM and do we actually need it?

    SCIM is the standard that lets your identity platform create, update, and deactivate accounts in downstream applications automatically. You need it when manual provisioning has become a bottleneck or when offboarding completeness has become an audit question, which for most companies happens at the same time.

  • Which platforms do you work with?

    For information services platforms, we work with Microsoft 365, Google Workspace, Okta, JumpCloud, Atlassian, Mimecast, Jamf, Salesforce, and comparable platforms. The platform itself is only part of the picture. What matters is who owns identity, how access is granted and removed, and how the systems connect.
