How to Protect Your Active Directory with Duo’s New MFA and Visibility Solutions

Why It Matters

By modernizing authentication and exposing hidden AD risks, Duo reduces a primary attack vector for enterprises and helps meet tightening regulatory MFA requirements. The solution enables security teams to defend critical on‑prem assets while maintaining operational continuity.

Key Takeaways

• Duo adds MFA to all AD authentication paths
• New visibility dashboards expose admin, service, guest accounts
• BloodHound integration maps attack paths across on‑prem identities
• Supports legacy protocols like NTLM and Kerberos
• Helps meet 2026 MFA compliance and audit requirements

Pulse Analysis

Active Directory remains the backbone of identity management for countless enterprises, yet its age and on‑prem nature make it a magnet for credential‑theft techniques such as Kerberoasting and Pass‑the‑Hash. Recent Cisco Talos research shows nearly half of identity‑focused attacks target AD, underscoring the urgent need for deeper insight into privileged and non‑human accounts. Traditional tools often provide fragmented data, leaving security operations blind to misconfigurations that attackers exploit.

Duo’s Active Directory Defense tackles this blind spot by feeding AD data into the Cisco Identity Intelligence (CII) dashboard, where administrators can monitor admin, service and guest identities in real time. The partnership with SpecterOps brings BloodHound Enterprise’s attack‑path analytics directly into the same console, allowing teams to prioritize remediation based on actual lateral‑movement scenarios. Crucially, Duo extends its award‑winning MFA to every AD authentication vector—including legacy NTLM and Kerberos logins—so organizations can enforce strong verification without disrupting legacy workflows.

Beyond threat mitigation, the solution aligns with evolving compliance expectations. Auditors now demand full MFA coverage, unified reporting, and visibility into non‑human identities, especially as AI‑driven agents proliferate. By consolidating visibility, MFA enforcement, and attack‑path intelligence, Duo enables a zero‑trust posture that protects legacy infrastructure while paving the way for cloud‑centric identity strategies. This integrated approach is poised to become a benchmark for enterprises seeking to secure their on‑prem identity estate without costly migrations.
