Enhancement Request: Enable Concurrent Kerberos and NTLM Authentication in Discovery

Please describe your idea in detail. What is your problem, why do you feel this idea is the best solution, etc.

Product/Module: Netwrix Privilege Secure – Discovery
Enable Discovery to negotiate and use Kerberos and NTLM concurrently (SPNEGO with intelligent fallback/selection) per target endpoint, without forcing a global single-method setting. The feature should allow adaptive, per-connection choice—prefer Kerberos when available (SPNs, time sync, mutual auth) and seamlessly fall back to NTLMv2 when Kerberos prerequisites are unmet—within the same discovery run.

Today, requires selecting a single auth method globally , which creates blind spots:

Kerberos-only runs fail on endpoints lacking valid SPNs, constrained delegation paths, or with clock skew/line-of-sight issues (isolated segments, one-way trusts, DMZ).
NTLM-only runs fail in domains where NTLM is disabled or restricted via policy, or where SMB signing & channel binding policies require Kerberos.
Mixed estates (legacy devices, appliances, lab/OT segments) cannot be reliably scanned in one pass, increasing operational overhead and risk of incomplete inventory.

How do you currently solve the challenges you have by not having this feature?

NA

Hi Vikram,

Thank you for submitting this idea. We will look into it.
