Top 33 Security & Identity Modernization Companies (2026)

Selection rule: every company below is one this site holds a research record for in security & identity modernization — a documented migration path, a service engagement, or a hub-scoped vendor profile — and the 33 that qualify are listed alphabetically, never ranked or scored. Paid Featured placements are labeled and do not change the ordering.

Approach labels below use the seven modernization options — why identity and security controls are usually replaced rather than refactored.

Engagement bands in this domain

Small: $40K–$80K
Mid-market: $100K–$200K
Enterprise: $250K–$500K

Spans are the published pricing tiers on this domain’s service pages (Zero Trust Architecture Design Services), cross-checked against the cost benchmarks. A company is placed in a band by its team size — this is a statement about the size of engagement firms of that scale typically deliver here, not a rate card. We publish no per-vendor rates.

Microsoft Entra Cloud Sync
Platform
Microsoft's cloud-managed successor to Entra Connect, reaching general availability in February 2021, replaces the on-premises sync server with a lightweight agent that needs only outbound connectivity. It ships free with any Entra ID tenant and is the only one of the two that handles disconnected multi-forest scenarios natively.
Microsoft Entra Connect
Platform
Microsoft's original on-premises sync engine for Active Directory to Entra ID, supporting password hash sync, pass-through authentication, and AD FS federation on a Windows Server the customer hosts and patches. Microsoft steers new deployments toward Entra Cloud Sync, but Entra Connect is still what most existing hybrid-identity environments run.
Microsoft Security Copilot
Platform
A generative-AI assistant that reached general availability on April 1, 2024, letting analysts query Defender, Sentinel, and Entra telemetry in natural language and run standalone agents for phishing triage. Billed separately by the security-compute-unit, it only works on Microsoft security tools already connected — it doesn't replace them.

Inclusion criteria: A company must have a published profile and documented category, migration-path, or service evidence in this domain. See the evidence threshold in our research methodology.

How to choose: Start with documented buyer fit (29 profiles) and specialty evidence (33), then narrow by team size (21) and location (21). Open a profile to verify the underlying experience before shortlisting.

This is an alphabetical market map, not an ordinal ranking. Paid Featured placements are labeled and do not imply a recommendation.

Security and identity modernization spans two supplier layers: IAM and identity-security platforms provide access management, identity governance, privileged access, directory, and verification capabilities; implementation partners design the target architecture, integrate applications, migrate identities, and establish operating controls. Evaluate platforms by supported identity types, policy depth, interoperability, deployment model, and lifecycle cost. Evaluate partners by IAM domain expertise, regulated-industry experience, migration evidence, delivery capacity, and independence from vendor incentives. The roster is alphabetical and does not declare a universal best provider.
