Adcyma vs One Identity
One Identity Manager is one of the most established IGA platforms in the market. It's built for complex, hybrid identity environments with deep Active Directory roots. Adcyma is built for companies on Entra ID and Active Directory that need governance without the enterprise project. Here's how to decide.

One Identity Manager is a comprehensive, traditional IGA platform with two decades of depth - especially strong in on-premises Active Directory and hybrid environments. It's built for large organizations with complex directory structures and dedicated IAM teams.
Adcyma is built for companies with 50-1,000 employees running on Microsoft Entra ID and Active Directory. Automated lifecycle management, access reviews, and compliance reporting - deployed in a day, no infrastructure required.
If you have a deeply complex AD forest with multiple domains, trusts, and legacy mainframe integrations, One Identity's heritage is hard to match. If your AD and Entra ID environment is more straightforward, Adcyma gets you to governance without the weight.
Where One Identity shines
One Identity Manager has been in the identity space for over 20 years, and that depth shows.
Unmatched Active Directory expertise.
Originally built as a Quest Software product, One Identity has the deepest AD heritage in the market. Complex forests, multiple domains, cross-trust relationships, legacy integrations - this is where it's genuinely best-in-class.
Comprehensive governance framework.
Full lifecycle management, advanced access certifications, separation of duties, role management, business process workflows, and extensive policy enforcement. It can model the most intricate organizational structures with precision.
Broad connector ecosystem.
One Identity connects to enterprise applications, databases, mainframes, and cloud platforms. The connector framework is mature, well-documented, and battle-tested.
On-premises deployment option.
For organizations with strict data sovereignty requirements or limited cloud adoption, One Identity Manager can be deployed entirely on-premises. Not many modern IGA platforms can say that.
Why mid-market companies struggle with One Identity
Architecturally complex.
One Identity Manager runs on SQL Server with a synchronization engine, web portal, and multiple service components. Setting up and maintaining this infrastructure requires database administration, server management, and ongoing tuning. For a five-person IT team, that's a significant operational burden before you've even configured any governance.
Implementation is a major project.
A One Identity deployment typically takes 6-12 months for a mid-market company. Infrastructure setup, connector configuration, workflow design, role modeling, testing, and training. You'll almost certainly need an implementation partner, adding cost and creating ongoing dependency.
The on-premises DNA shows.
While One Identity offers cloud options (Manager On Demand), the platform's architecture reflects its on-premises origins. If your environment is primarily cloud-based with Microsoft 365 and Entra ID, you're carrying architectural weight designed for a different era of IT.
The cost structure is enterprise-grade.
Between licensing, implementation partner fees, infrastructure costs (if on-premises), and ongoing maintenance, a One Identity deployment for a mid-market company typically lands between €80,000 and €250,000+ in the first year. Annual costs remain significant after that.
The skill gap is real.
One Identity Manager requires specialized knowledge. Configuring custom workflows, building synchronization profiles, tuning the governance model - these aren't things a generalist IT admin picks up in a training course. This means either ongoing consulting costs or a specialized hire.
Built for simplicity - across Entra ID and Active Directory
Adcyma doesn't try to replace One Identity for deeply complex hybrid environments with mainframe integrations and multi-forest trusts. Instead, it's built for companies that run on Entra ID and Active Directory and need governance without the enterprise project.
No infrastructure to manage.
Adcyma is SaaS. Connect to your Entra ID tenant and Active Directory and you're operational. No SQL Server, no sync engine, no application servers. Your IT team manages governance, not infrastructure.
Automated lifecycle management.
Define role-based access once. When someone joins, moves, or leaves, the right changes happen automatically. No manual provisioning checklist. No forgotten offboarding steps.
Access reviews built for mid-market.
Run review campaigns with clear ownership, deadlines, and tracking. Not an afterthought bolted onto a bigger platform - a core feature designed for teams that don't have a dedicated IAM function.
Compliance without the project.
Pre-built reporting for SOC 2, ISO 27001, and NIS2. Pull what your auditor needs from one place.
Operational in a day.
No implementation partner. No six-month project. Connect, configure, and start governing.

Which one should you choose?
Choose One Identity if:
- You have a deeply complex on-premises AD environment with multiple forests, cross-trust relationships, and legacy integrations
- You need to govern identities across mainframes, databases, or highly specialized legacy systems alongside cloud apps
- Data sovereignty requires a fully on-premises IGA deployment
- You have a dedicated IAM team or budget for ongoing specialized consulting
- Your governance requirements include complex separation of duties and role modeling
- You have 1,000+ employees with intricate organizational structures
Choose Adcyma if:
- Your environment is Microsoft Entra ID, Active Directory, or a hybrid of both
- You have a straightforward AD setup (single forest, standard configuration) and/or are cloud-first
- You have 50-1,000 employees
- Your IT team is small and wears many hats
- You need governance for SOC 2, ISO 27001, or NIS2 compliance without a year-long project
- You want something operational this week
Questions we hear from companies evaluating both
Yes. Adcyma supports both Active Directory and Entra ID, including hybrid environments. If your setup is a single AD forest syncing to Entra ID via Entra Connect - which describes most mid-market companies - Adcyma governs both layers. If you have a deeply complex multi-forest AD environment with legacy trust relationships and mainframe integrations, that's where One Identity's two decades of AD heritage gives it an advantage.
One Identity has been investing in their cloud offering (Manager On Demand). It reduces infrastructure burden but doesn't fundamentally change the platform's complexity or the need for specialized expertise. The governance model, connector framework, and configuration approach are the same.
If you're actively moving to a cloud-first identity model, starting with a cloud-native governance tool makes sense. Implementing an on-premises-heritage platform during a cloud migration adds complexity to both projects. Get governance in place for where you're going, not where you've been.
Longevity is real and worth acknowledging. One Identity has a proven track record with large enterprises. The question is whether that enterprise track record translates to value for a 200-person company on Entra ID. Maturity in platform doesn't always mean fit for your situation.
