TL;DR: Treat public RDP as an exception. Put RDP behind a VPN or RD Gateway, enforce phishing-resistant MFA, allowlist source IPs, and monitor aggressively.
The 2025 reality
Always-on internet scanning means any exposed 3389/TCP gets hit—often within minutes. Less exposure, more layers, and better identity controls are your best risk reducers.
Do this first (30 minutes)
- Close public 3389 at the edge. If you must keep it, set strict source IP allowlists.
- Front RDP with RD Gateway + MFA. Use NPS/Entra ID (or equivalent) and avoid SMS factors.
- Force Network Level Authentication (NLA) and modern encryption. Disable weak ciphers.
If you’re planning to hide RDP behind a VPN, but you’re not yet familiar with how to set up a client VPN on Windows, the step-by-step SoftEther guide below is a good starting point.
Reference architecture that works
User → VPN (or ZTNA) → RD Gateway (with MFA) → Target host via RDP. This removes direct internet exposure and centralizes auditing and policy.
If you need to connect an entire branch office network to your Japan-based Windows VPS — not just individual admin PCs — the site-to-site SoftEther bridge pattern below is a practical option.

If you still need a basic walkthrough of how to connect to your Windows VPS over Remote Desktop once your secure access path is in place, the guide below covers the fundamentals.
Remote Desktop Setup Guide for Your Windows VPS
Hardening checklist
- Perimeter: default deny, allowlist only known sources.
- Identity: MFA everywhere for admins; rotate credentials and block legacy protocols.
- Session policy: disable drive/clipboard/device redirection unless required.
- Accounts: lockout thresholds and alerts on brute-force patterns.
- OS: keep RDP/RPC patches current; limit local admins; enable firewall on hosts.
Monitor like you mean it
- Alert on spikes in failed sign-ins or any direct 3389 hits from the internet.
- Centralize logs (gateway + hosts). Review weekly; respond to anomalies.
