Dynacop vs Rublon for Windows Logon and RDP
Both products offer focused MFA for Windows console and RDP sign-ins and work without Active Directory. The difference is in the detail: Dynacop records the real person behind a shared account, accepts any authenticator offline, and blocks attacker IPs on the machine; Rublon offers a broader range of authentication methods.
This comparison covers the Rublon MFA for Windows Logon and RDP connector. RD Gateway and RD Web Access are separate Rublon integrations.
The short answer
- If you want to record the real person behind a shared account
- If you want to keep using the authenticator your team already has offline (no proprietary-app requirement)
- If you want Windows MFA and attacker-IP blocking in one product
- If you want a low minimum and the first 10 users free
- If you want broad authentication methods like push, FIDO2/security keys, SMS, and phone
- If you need wider RDS coverage via Rublon's separate RD Gateway/Web connectors
- If you prefer a broader MFA toolkit beyond Windows sign-in
Sourced comparison
Per-person MFA on console and RDP sign-ins
Console and RDP; RDP-only or both can be chosen
No; local and domain accounts are supported
No — “Microsoft Active Directory is not required. You can use Workgroup Accounts”
Each person verifies with their own factor; the record shows the real person
Documented model: identity is mapped by Windows username (UPN/NTLM/sAMAccountName). Our assessment: a shared username doesn't split into Dynacop-style per-person records in the standard flow
Any RFC 6238-compliant TOTP — online and offline
Online: third-party TOTP (Google/Microsoft Authenticator, etc.) is supported. Offline: the Rublon Authenticator is required — “third-party ... not supported yet”
TOTP only (deliberate simplicity)
Push · FIDO/security key · SMS · phone · YubiKey · QR · email
Shield correlates source IP and blocks those over threshold in the machine's Windows Firewall
No equivalent behavior documented in the Windows Logon/RDP docs we reviewed
Isolated multi-customer workspaces, license-free technicians, and a customer portal where the end customer sees and revokes their own access
MSP partner program: multi-customer AD management and NFR licenses. No customer-facing access portal documented in the docs we reviewed
First 10 users free; no minimum on the paid plan
Free plan: 1 protected user. Paid Business: minimum 15 licenses
Single plan, per protected user
Per-user Free / Business / Enterprise plans
Where they're equal or similar
- Both offer focused MFA for Windows console and RDP sign-ins.
- Both work without Active Directory, with local/workgroup accounts.
- Both support offline verification.
- Both use a per-user/per-person pricing logic.
Three key differences, in detail
Documented fact: Rublon identifies users by their Windows username (UPN, NTLM, or sAMAccountName); no capability to distinguish individuals within a shared account is documented.
Dynacop assessment: Dynacop resolves identity from the entered code; even when the shared “administrator” account stays in place, the audit record shows the real person.
Shared-account person resolution →Documented fact: Rublon supports third-party TOTP apps (Google/Microsoft Authenticator, etc.) for online authentication, but offline access requires the Rublon Authenticator — “third-party ... not supported yet”.
Dynacop assessment: Dynacop accepts any RFC 6238-compliant TOTP app both online and offline; your team keeps the authenticator it already uses.
Windows Login MFA →Documented fact: the Rublon Windows Logon/RDP docs we reviewed do not document automatically blocking a failed-login source in the target machine's firewall.
Dynacop assessment: Shield does this in the same product — it verifies the authorized user with MFA and blocks the attacker IP on the machine.
Explore Shield →Which is the better fit?
If your priority is the real person behind a shared account, proprietary-app-free offline verification, attacker-IP blocking, and a low barrier to entry (first 10 users free, no minimum).
If you need a broad range of authentication methods like push, FIDO2/phishing-resistant keys, SMS, and phone, or wider remote-access coverage such as RD Gateway/Web. Dynacop is deliberately TOTP-focused.

Frequently asked questions
What's the biggest difference?
Both focus on AD-free Windows console/RDP MFA. Dynacop records the real person on a shared account, accepts any TOTP app offline, and blocks attacker IPs on the machine. Rublon offers a broader range of methods such as push, FIDO2, and SMS.
Does Rublon support third-party authenticator apps?
Yes — for online authentication, TOTP apps like Google Authenticator, Microsoft Authenticator, and Authy can be used. However, Rublon's current Windows offline-mode documentation states that offline use requires the Rublon Authenticator and that third-party passcodes aren't supported yet. Dynacop works with any RFC 6238 TOTP app both online and offline.
Does Rublon have a free plan?
Yes, Rublon MFA Free is for one protected user. The paid Business subscription requires a minimum of 15 licenses. In Dynacop, the first 10 users are free and there's no minimum on the paid plan.
How is a shared Administrator account recorded?
In Dynacop, each person signing in with the shared account verifies with the code on their own phone; the record is kept under the real person. Since Rublon maps identity by Windows username (UPN/NTLM/sAMAccountName), a Dynacop-style per-person distinction under one shared username isn't documented in the standard flow.
