If your organisation is evaluating multi-factor authentication (MFA) for your workforce, two platforms come up consistently in every Indian enterprise shortlist: Cisco Duo and Microsoft Entra ID (formerly Azure Active Directory / Azure AD). Both are enterprise-grade identity and access platforms. Both are widely deployed in India. But they are built on different design philosophies and serve different organisational contexts best.
This guide provides a direct comparison on the dimensions that matter for an Indian IT decision-maker: MFA depth, device trust, deployment complexity, pricing, Microsoft 365 integration, and Zero Trust capability.
Quick Summary
| Dimension | Cisco Duo | Microsoft Entra ID |
|---|---|---|
| Core strength | Device trust + MFA for any environment | Deep Microsoft ecosystem integration |
| MFA types | Push, SMS, phone, hardware token, biometric, TOTP | Push (Authenticator), FIDO2, TOTP, SMS (legacy) |
| Device trust | Full device posture check (all tiers) | Compliant device via Intune (extra cost) |
| Non-Microsoft app support | Excellent — 2,000+ app integrations | Good via SAML/OIDC but Microsoft-first experience |
| On-prem LDAP/AD integration | Native authentication proxy | Requires Entra Connect sync |
| SSO | Duo Premier only | Included in Entra ID P1/P2 |
| ZTNA | Duo Network Gateway (Premier) | Entra Private Access (Global Secure Access) |
| Pricing model | Per user / per year (paid add-on) | Bundled with Microsoft 365 plans |
| Best for | Multi-vendor environments, device-trust focus | Microsoft-first organisations on M365 |
Understanding Entra ID — It Is Not Just MFA
A critical clarification before comparison: Microsoft Entra ID is not an MFA tool — it is a complete Identity Provider (IdP) and directory service. Every Microsoft 365 business already has Entra ID Free tier included. Entra ID Free provides:
- Cloud identity for Microsoft accounts
- Microsoft Authenticator app for basic MFA
- SSO for Microsoft applications
- Basic conditional access (limited without P1)
The paid tiers add meaningful capability:
Entra ID P1 (included in M365 Business Premium, E3):
- Full Conditional Access policies
- Entra Connect for on-prem AD sync
- Groups and Dynamic membership
- Identity Governance basics
Entra ID P2 (included in M365 E5 or standalone):
- Privileged Identity Management (PIM) — just-in-time admin access
- Entra Identity Protection — risk-based conditional access (risky users, risky sign-ins)
- Access Reviews
For most Indian businesses already on Microsoft 365 Business Premium or E3, Entra ID P1 is already paid for. The question is: does Duo add anything meaningful on top of what you already have?
MFA Depth — Where Duo Has an Advantage
Device Trust Without Intune Requirement
This is the most important practical difference for Indian businesses.
Microsoft Entra ID can enforce compliant device access via Conditional Access — but "compliant device" requires the device to be enrolled in Microsoft Intune (Mobile Device Management). Intune is a separate license (included in M365 Business Premium and E3/E5, but not in lower SKUs). Entra device compliance checks require Intune enrollment — which means IT must deploy and manage Intune, a non-trivial implementation.
Cisco Duo checks device health — OS patch level, disk encryption, browser version, certificate status, jailbreak detection — without requiring MDM enrollment. Duo Advantage performs these checks as part of the authentication flow, without needing every device pre-enrolled in a management platform. For businesses with BYOD (bring your own device) policies or where IT does not manage all employee devices, this is a significant practical advantage.
Real-world implication: An Indian professional services firm with 100 employees, half of whom use personal laptops for work, can enforce device hygiene with Duo Advantage without enrolling every personal device in Intune. With Entra alone, this requires Intune — which means either mandating personal device MDM enrollment (sensitive for employees) or leaving BYOD devices unchecked.
MFA for On-Prem and Legacy Applications
Entra ID handles MFA for cloud apps natively. For on-prem applications — legacy web apps, custom business applications, VDI, SSH, RDP — Entra ID requires Application Proxy or custom ADFS configuration. This works but requires more infrastructure.
Cisco Duo connects to on-prem applications via its authentication proxy, which installs on a Windows server and integrates with Active Directory via LDAP/RADIUS. Duo can add MFA to virtually any on-prem application — including ERP systems, legacy portals, SSH logins — without modifying the application or changing its authentication architecture. This is particularly valuable for Indian businesses with significant on-prem or hybrid application stacks.
Non-Microsoft Application Support
Entra ID works with any SAML 2.0 or OIDC application — the integrations exist. But the experience is Microsoft-first, and some third-party app integrations require more configuration effort than native Microsoft ones.
Cisco Duo has over 2,000 pre-built application integrations — it is vendor-agnostic by design. Duo was built as an independent MFA layer that works with Cisco and non-Cisco environments alike. For Indian businesses using Fortinet VPN, AWS, Salesforce, SAP, and Zoho alongside Microsoft 365, Duo's breadth of native integrations reduces implementation friction.
SSO Comparison
Entra ID P1/P2 includes a full SSO portal — the Microsoft My Apps portal — where users can access all Entra-connected apps with one login. This is deeply integrated with Microsoft 365 and Azure services.
Cisco Duo Premier includes Duo SSO — a similar app portal. For non-Microsoft shops or for organisations wanting an SSO layer independent of Microsoft's identity infrastructure, Duo SSO is strong. However, organisations already on M365 with Entra ID P1 have SSO included — adding Duo Premier's SSO on top may be redundant unless the use case is specifically non-Microsoft app coverage.
Zero Trust Network Access
Microsoft Entra Private Access (Global Secure Access)
Microsoft's ZTNA solution, available in Entra P1/P2. Replaces traditional VPN for private application access. Traffic routes through Microsoft's Global Secure Access infrastructure. Strong integration with Microsoft Conditional Access — device compliance check, identity verification, and network access in a unified policy. Still maturing as of 2026 compared to established VPN replacements.
Cisco Duo Network Gateway
Duo's ZTNA capability, included in Duo Premier. Provides VPN-less access to on-prem web applications. Users authenticate via Duo MFA, device posture is checked, and access is granted to specific applications — not the entire network. Integrates with Cisco Secure Access (SSE) for a broader SASE architecture.
Verdict: Microsoft's ZTNA is more tightly integrated with M365 and Azure environments but is newer. Cisco's ZTNA is more mature for heterogeneous environments and fits naturally into the Cisco Security portfolio (ISE, Secure Firewall, XDR).
Pricing — India 2026
Microsoft Entra ID
Entra ID Free is included with every Microsoft 365 subscription. The paid tiers are typically bundled:
- Entra ID P1: included in Microsoft 365 Business Premium (₹2,530/user/month includes M365 E3-equivalent features) — you are not buying Entra separately
- Entra ID P2: included in Microsoft 365 E5 or available standalone
If your organisation is on M365 Business Premium or E3/E5, you already have Entra ID P1/P2 included. The "cost" of Entra ID MFA is the premium you pay for a higher Microsoft 365 SKU — not an independent line item.
Cisco Duo
Duo is a dedicated per-user subscription — it is not bundled with any Microsoft 365 license. You pay for Duo separately, on top of your existing Microsoft 365 investment.
The key pricing question: If you are already on M365 Business Premium with Entra P1 included, is Duo worth the additional cost?
The answer depends on your requirements:
- Pure MFA + SSO for Microsoft apps, company-managed Windows devices: Entra P1 is likely sufficient
- BYOD device trust enforcement, non-Microsoft app MFA, hybrid/on-prem MFA: Duo Advantage adds material security value
- Zero Trust architecture across multi-vendor environment: Duo Premier is worth the investment

When to Choose Cisco Duo
- You have non-Cisco, non-Microsoft infrastructure — Fortinet VPN, AWS, on-prem legacy apps — and need consistent MFA across everything
- BYOD device trust is important — you want to check device health without forcing Intune enrollment on personal devices
- On-prem applications — you need MFA on legacy applications that Entra Application Proxy cannot easily reach
- You are building a Cisco Security stack — Duo + Cisco Secure Firewall + ISE + XDR is a deeply integrated architecture
- Your Microsoft 365 SKU does not include Entra P1 — lower-tier M365 plans, or Google Workspace environments
When Microsoft Entra ID Is Sufficient
- You are fully Microsoft-first — all apps are M365/Azure, all devices are company-managed Windows on Intune
- You have M365 Business Premium or E3/E5 — Entra P1/P2 is already included
- Identity Governance is the priority — PIM, access reviews, privileged identity — Entra P2 leads here
- You want a single-vendor Microsoft identity stack — one admin console, one support vendor, unified policies
Running Both — Is It Redundant?
Some Indian enterprises run both Cisco Duo and Microsoft Entra ID. This is not redundant in all cases:
- Entra handles Microsoft 365 SSO and Microsoft-cloud Conditional Access
- Duo handles VPN MFA, on-prem app MFA, device trust for BYOD, and non-Microsoft app integration
This layered approach gives the strongest coverage but increases licensing cost. It makes sense for large enterprises (500+ users) with complex hybrid environments. For most Indian SMBs, choosing one platform and implementing it well is more practical.
Frequently Asked Questions
Can Cisco Duo replace Microsoft Entra ID entirely? No. Entra ID is the cloud directory for Microsoft 365 — it manages user identities, licenses, and Microsoft app access. Duo cannot replace this. Duo adds MFA and device trust on top of Entra (or Active Directory). They are complementary.
Does Duo work without Active Directory? Yes. Duo can authenticate users via its own user directory, LDAP, or directly through cloud application integrations. However, most Indian enterprise deployments use Duo alongside on-prem Active Directory or Entra ID.
Is Cisco Duo compliant with RBI and SEBI MFA requirements? Yes. Cisco Duo meets MFA requirements specified by RBI's IT Framework for Banks, SEBI's Cyber Security Circular, and ISO 27001 requirements. Cloudfy provides compliance documentation to support your audit process.
What happens if Cisco Duo is unavailable during an authentication event? Duo has 99.9% SLA and geo-redundant infrastructure. If Duo is temporarily unavailable, you can configure a failover policy — allow login (with logging), block login, or use backup codes. The right policy depends on your risk posture.
