Block the #1 Ransomware Initial Access Vector — Unsecured Windows RDP

RDP is the initial access vector in over 50% of ransomware attacks. OnePAM eliminates this risk with identity-verified SSO, MFA enforcement, and gateway-based RDP isolation.

Overview

Cut Off Ransomware's Favorite Entry Point

The data is clear: Remote Desktop Protocol (RDP) is the single most exploited initial access vector for ransomware attacks. Industry reports from Sophos, CrowdStrike, and CISA consistently show that 50-70% of ransomware incidents begin with compromised RDP access. OnePAM breaks this kill chain at the earliest stage by replacing password-based RDP with SAML/OIDC SSO and MFA, isolating RDP ports behind a gateway, and recording every session for anomaly detection.

Local Agent

Install the OnePAM agent on each Windows server. The agent intercepts RDP authentication and enforces SAML/OIDC SSO with Kerberos and Protected User support before granting desktop access — no gateway required.

Gateway RDP Proxy

Run a dedicated OnePAM gateway with native RDP protocol support. Users authenticate via SAML/OIDC at the gateway, which brokers the RDP session using Kerberos NLA. No agent needed on target servers.

RDP Security Risks

How Ransomware Exploits RDP

Without identity-based RDP access, these risks threaten your Windows servers every day.

50-70% of ransomware incidents use compromised RDP as the initial access vector (Sophos, CrowdStrike, CISA)

RDP credentials are sold on dark web markets for $5-50 per server

Automated RDP brute-force tools run 24/7 against exposed endpoints

Average ransomware dwell time via RDP is 5 days — enough to map the network and maximize damage

The Challenge

RDP Security Challenges

These are the risks organizations face with traditional RDP authentication.

Password-Based Authentication

RDP uses AD passwords by default. Weak, reused, or stolen passwords provide immediate server access.

Exposed to the Internet

Millions of Windows RDP endpoints are directly reachable from the internet.

No MFA by Default

Windows RDP has no built-in MFA. Password-only access persists.

Credential Markets

Dark web markets sell RDP access credentials for $5-50 per server.

Lateral Movement

Once inside one server via RDP, attackers move laterally with the same credentials.

Slow Detection

RDP-based ransomware dwell time averages 5 days before detection.

The OnePAM Solution

How OnePAM Prevents RDP-Based Ransomware

Step-by-step guide to deploying identity-based Windows RDP access.

Eliminate Passwords

Replace password-based RDP with SAML/OIDC SSO. No passwords to brute-force or steal.

Credential stuffing and brute-force tools have no target.

Enforce MFA

Require MFA on every RDP session. A stolen password alone cannot grant access.

This blocks the vast majority of ransomware initial access attempts.

Isolate RDP Ports

In gateway mode, RDP ports are unreachable from the network.

Zero-day exploits cannot reach the target servers.

Detect Anomalies

OnePAM logs every RDP session with identity, location, device, and behavior context.

Unusual patterns trigger alerts. Ransomware reconnaissance is detected early.

Record Sessions

Visual session recording provides forensic evidence and deters malicious insiders.

Complete evidence for incident response.

Business Impact

Ransomware Prevention Impact

Measurable security and operational outcomes from deploying OnePAM Windows RDP SSO.

Eliminate #1 Attack Vector

RDP is the top ransomware entry point. OnePAM eliminates it with identity-verified access.

100% password attacks blocked

Dark Web Credentials Useless

Stolen RDP credentials are worthless — they can't bypass SAML/OIDC SSO and MFA.

Stolen creds rendered useless

Block Automated Brute-Force

No RDP login interface is exposed. There's nothing to brute-force.

Zero brute-force surface

Break Lateral Movement

Identity-verified access per server prevents credential-based lateral movement.

Lateral movement blocked

Reduce Cyber Insurance Cost

Insurers offer lower premiums for MFA on RDP. OnePAM provides documented evidence.

Frequently Asked Questions

RDP Ransomware Prevention FAQ

Common questions about Windows RDP SSO and zero-day protection.

Is RDP really the #1 ransomware attack vector?

Yes. Multiple industry reports consistently identify compromised RDP in 50-70% of ransomware incidents.

Can OnePAM prevent all ransomware attacks?

OnePAM eliminates RDP as an attack vector — the single most common one. It should be part of a defense-in-depth strategy.

How does OnePAM help with cyber insurance?

Cyber insurers require MFA on RDP. OnePAM provides documented MFA enforcement, session recording, and access controls.

How quickly can OnePAM be deployed?

In gateway mode, OnePAM can be deployed and protecting servers within 2-4 hours.
