Identity has become the new security perimeter. For law firms, protecting usernames and passwords is no longer enough when attorneys access confidential client files from courtrooms, home offices, mobile devices, and cloud-based legal applications. A single compromised account can expose privileged communications, intellectual property, litigation strategies, financial records, and personally identifiable information.
This is why many legal practices are replacing traditional Active Directory-only environments with modern Identity and Access Management (IAM) platforms. Two of the most widely evaluated solutions are Okta and Microsoft Entra ID (formerly Azure Active Directory).
At first glance, comparing them seems straightforward:
“Which platform costs less per user?”
In reality, per-seat licensing is only one piece of the equation. The overall investment also depends on existing Microsoft licensing, application integrations, help desk workload, security features, deployment complexity, compliance obligations, and long-term administrative overhead.
This guide examines both platforms specifically from the perspective of law firms, helping managing partners, CIOs, IT directors, and legal technology managers understand where the real costs originate.
Executive Overview
For many firms already invested in Microsoft 365, Microsoft Entra ID can deliver a lower overall cost because identity services are tightly integrated with the Microsoft ecosystem.
However, organizations with diverse cloud environments, hundreds of third-party SaaS applications, or mixed operating systems may find that Okta reduces operational complexity despite a potentially higher subscription cost.
The most economical platform is not necessarily the one with the lowest monthly license—it is the one that minimizes administration, improves security, and supports long-term business growth.
Why Identity Security Matters More for Law Firms
Legal organizations handle information that is both commercially valuable and legally protected.
Examples include:
- Attorney-client communications
- Mergers and acquisitions documents
- Litigation evidence
- Intellectual property
- Financial disclosures
- Employment records
- Medical documentation
- Government contracts
- Cross-border legal matters
Unlike many industries, a single compromised account may expose thousands of confidential case documents.
Identity security therefore becomes a primary risk management concern rather than simply an IT function.
Understanding the Two Platforms
Okta
Okta is a cloud-native identity platform designed to provide authentication and access management across a wide variety of applications, cloud providers, and operating systems.
Typical capabilities include:
- Single Sign-On (SSO)
- Multi-Factor Authentication (MFA)
- Lifecycle Management
- Adaptive authentication
- Passwordless authentication
- Identity governance
- Universal directory
- API access management
Because Okta is vendor-neutral, it integrates with thousands of third-party business applications.
Microsoft Entra ID
Microsoft Entra ID is Microsoft’s enterprise identity platform and forms the authentication foundation for Microsoft 365 and many Azure services.
Core capabilities include:
- Single Sign-On
- Multi-Factor Authentication
- Conditional Access
- Identity Protection
- Privileged Identity Management (PIM)
- Passwordless authentication
- External identities
- Identity governance
Organizations already standardized on Microsoft technologies often find that Entra ID fits naturally into existing workflows.
Comparing Licensing Approaches
Although both platforms license users, their pricing philosophy differs.
Okta
Licensing is generally modular.
Organizations often purchase:
- Single Sign-On
- MFA
- Lifecycle Management
- Identity Governance
- Advanced Server Access
- API Access Management
This allows firms to select only the features they need but can also increase costs as additional modules are added.
Microsoft Entra ID
Microsoft commonly packages identity capabilities within broader Microsoft licensing plans or premium identity tiers.
Depending on the organization’s Microsoft subscriptions, some identity features may already be included, while advanced governance and privileged access capabilities require higher-tier licensing.
For firms heavily invested in Microsoft technologies, this bundling can simplify procurement and budgeting.
Beyond the Per-Seat License
The monthly user subscription represents only one portion of the total investment.
| Cost Component | Okta | Microsoft Entra ID |
|---|---|---|
| User licensing | High visibility | Often bundled with Microsoft licensing |
| Initial deployment | Medium | Medium |
| Application integration | Low–Medium | Low for Microsoft ecosystem; higher for some third-party applications |
| Administrator training | Medium | Medium |
| Identity governance | Additional licensing may apply | Higher-tier licensing may be required |
| Ongoing administration | Medium | Medium |
| Support and maintenance | Medium | Medium |
Organizations should evaluate these operational costs alongside subscription pricing.
Existing Technology Stack Has a Major Impact
One of the most significant cost drivers is the firm’s existing IT environment.
Microsoft-Centric Firms
Law firms using:
- Microsoft 365
- Windows endpoints
- Microsoft Teams
- SharePoint
- Exchange Online
- Intune
- Defender
may find Microsoft Entra ID offers a more streamlined identity experience with fewer integration requirements.
Multi-Vendor Environments
Organizations relying on:
- Google Workspace
- Salesforce
- ServiceNow
- Legal practice management software
- Cloud-native applications
- Linux or macOS devices
may benefit from Okta’s broad application ecosystem and vendor-neutral architecture.
In these environments, reduced integration effort can offset higher licensing costs.

Hidden Costs That Affect Per-Seat Value
Help Desk Workload
Password resets remain one of the most common IT support requests.
Features such as self-service password reset and passwordless authentication can reduce support tickets and lower operational costs.
User Provisioning
When attorneys or support staff join or leave the firm, identity platforms can automate:
- Account creation
- Role assignment
- License allocation
- Access revocation
Automation reduces administrative effort and minimizes the risk of orphaned accounts.
Compliance Preparation
Law firms frequently need to demonstrate that access to sensitive information is properly managed.
Identity platforms can simplify:
- Audit logging
- Access reviews
- Authentication reporting
- Privileged account monitoring
These capabilities can reduce the time spent preparing for client security assessments or regulatory reviews.
Integration with Legal Technology
Modern law firms rarely operate with a single software vendor.
Common integrations include:
- Document Management Systems (DMS)
- Practice management software
- E-discovery platforms
- Time and billing applications
- Client portals
- Digital signature services
- Secure file-sharing solutions
The complexity of integrating these systems should be considered when evaluating overall costs.
Scalability for Growing Firms
Small Law Firms
Organizations with fewer users often prioritize:
- Easy deployment
- Minimal administration
- Cloud-based management
- Secure remote access
Bundled licensing may be particularly attractive if Microsoft services are already in use.
Mid-Sized Firms
Growth typically introduces:
- Multiple office locations
- Hybrid work
- Additional SaaS applications
- External collaborators
- More complex identity policies
Automation and centralized management become increasingly valuable.
Large National or International Firms
Enterprise legal organizations often require:
- Identity governance
- Privileged access controls
- Automated access reviews
- Federation with client environments
- High availability
- Advanced reporting
Operational efficiency becomes just as important as licensing costs.
Compliance Considerations
Identity platforms support broader security and governance initiatives that many law firms follow.
Relevant frameworks include:
| Framework | Relevance |
|---|---|
| NIST Cybersecurity Framework (CSF) | Identity and access management as part of enterprise risk management |
| NIST SP 800-53 | Access control and identity-related security controls |
| ISO/IEC 27001 | Information Security Management Systems (ISMS) |
| CIS Controls | Secure authentication and access management |
| SOC 2 | Demonstrating effective logical access controls |
Neither platform guarantees compliance, but both can help organizations implement identity controls that support legal, contractual, and client security expectations.
AI and Identity Security
Artificial intelligence is beginning to influence identity management in several ways.
Emerging capabilities include:
- Risk-based authentication decisions
- Behavioral anomaly detection
- Impossible travel detection
- Suspicious sign-in analysis
- Automated identity risk scoring
- Intelligent access recommendations
These features can improve security without significantly increasing administrative overhead, provided they are configured appropriately.
Decision Guide
| Scenario | Platform That May Fit Best | Why |
|---|---|---|
| Firm already standardized on Microsoft 365 | Microsoft Entra ID | Existing ecosystem integration may reduce overall costs |
| Firm uses numerous non-Microsoft SaaS applications | Okta | Broad integration catalog and vendor-neutral architecture |
| Small practice with limited IT resources | Microsoft Entra ID (if already licensed) | Potentially lower incremental investment |
| Rapidly growing regional firm | Depends on application landscape | Integration requirements become a key factor |
| Large multinational legal organization | Either platform | Decision should prioritize governance, scalability, and operational efficiency over license cost alone |
Best Practices Before Comparing Per-Seat Pricing
Before requesting vendor quotes, firms should:
- Inventory all business applications that require authentication.
- Review existing Microsoft licensing to identify included identity features.
- Estimate the number of external users, contractors, and temporary staff.
- Evaluate long-term identity governance requirements.
- Assess integration needs with legal software and client systems.
- Include training, administration, and support costs in the comparison.
- Consider future expansion rather than current headcount alone.
Frequently Asked Questions
Is Microsoft Entra ID always cheaper than Okta?
Not necessarily. Organizations already licensed for Microsoft 365 may realize lower incremental costs, but firms with complex multi-vendor environments may find that Okta reduces integration effort and administrative overhead.
Does Okta offer stronger security?
Both platforms provide robust enterprise identity security. The overall security outcome depends on how features such as MFA, conditional access, privileged access management, and identity governance are implemented and maintained.
Which platform is easier to manage?
This depends largely on the existing IT environment. Firms deeply invested in Microsoft technologies often benefit from Entra ID’s native integration, while organizations with diverse application ecosystems may prefer Okta’s centralized identity management capabilities.
Should law firms choose based only on license cost?
No. Licensing is only one component of total ownership. Integration complexity, administration, user experience, support requirements, compliance needs, and future scalability typically have a greater impact on long-term value.
Conclusion
Choosing between Okta and Microsoft Entra ID is less about identifying the lowest price per user and more about determining which platform aligns with the firm’s technology strategy and operational needs.
For Microsoft-centric law firms, Entra ID can often provide a cost-efficient identity foundation by leveraging existing investments in Microsoft services. For firms operating across a broader mix of cloud applications and vendors, Okta’s flexibility and extensive integration capabilities may justify a higher subscription cost through reduced operational complexity.
When evaluating identity platforms, legal organizations should compare total cost of ownership, considering licensing, deployment, integration, administration, governance, compliance support, and long-term scalability. A platform that strengthens security while simplifying day-to-day operations will often provide greater value than one chosen solely for its initial per-seat price.
