Question: What does “RDP / RDP Web” mean in Sangfor (深信服) 运维安全管理系统 connection?

Answer:

In a Sangfor 运维安全管理系统 (Sangfor OSM / 运维安全审计), RDP and RDP Web refer to ways of connecting to a Windows server through Remote Desktop Protocol.

1. RDP

RDP = Remote Desktop Protocol

It is Microsoft’s native remote desktop protocol.

Typical flow:

Your PC
  |
  | RDP client (mstsc.exe)
  |
  | TCP 3389
  |
Windows Server

Example:

mstsc.exe
→ server IP
→ username/password
→ Windows desktop

You get a full Windows GUI session.

2. RDP Web

RDP Web = browser-based RDP connection

Instead of installing Microsoft’s Remote Desktop client:

Browser
   |
HTTPS
   |
Sangfor Gateway
   |
RDP protocol
   |
Windows Server

You open:

https://sangfor-management-system/

The Sangfor system launches a web terminal (usually HTML5-based) and proxies the RDP session.

Advantages:

No need to install mstsc
Works on Linux/macOS browsers
Easier auditing
Sangfor can record the session

3. Why Sangfor has this option

A normal RDP connection:

Engineer
   |
   | RDP
   |
Server

has problems:

No centralized control
Hard to audit
Password sharing risk
Cannot easily record operations

Sangfor adds a bastion host:

Engineer
        |
        |
        v
+----------------+
| Sangfor OSM    |
| Bastion Host   |
|                |
| Audit          |
| Permission     |
| Recording      |
+----------------+
        |
        |
        v
 Windows Servers

The Sangfor system can:

authenticate users
check permission
hide real server passwords
record screen operations
log commands
provide approval workflow

4. Difference

Feature	RDP	RDP Web
Client	Windows mstsc	Browser
Protocol	RDP directly	RDP tunneled through Sangfor
Install software	Yes	No
Audit	Depends	Built-in
Session recording	Limited	Usually supported
Works on Mac/Linux	Harder	Easy

5. In an enterprise environment

Usually the architecture is:

Employee laptop
       |
       |
 HTTPS 443
       |
Sangfor 运维安全管理系统
       |
       |
 RDP 3389
       |
Windows Server 2012 / 2016 / 2022

So if you see:

Connection Type:
  RDP
  RDP Web

choose:

RDP → if you have Windows Remote Desktop client and need better performance
RDP Web → if you want browser access or the company requires bastion auditing

For banking / large enterprise environments (like HSBC-style environments), RDP Web through a bastion host is very common because every admin action must be recorded.
