First, a disclosure: Yuxinan is a multi-site networking product made by Siwenlide, and we are a stakeholder in this article. So this piece won’t take swipes at competitors—it just lays out the differences between the two things clearly, so you can judge for yourself which one fits your case. In one sentence: an ordinary VPN solves “connecting one device to a network,” while multi-site networking solves “merging several networks into one”—opening stores (especially two or more) calls for the latter, because POS, surveillance, and inventory need the whole network to interconnect between stores, not just one or two people dialing in remotely.
1. First, Clarify the Concepts: One Connects a “Point,” the Other Connects a “Network”
- Ordinary VPN (dial-up VPN): the model is “a point joining a network.” A computer dials into the VPN and that computer can reach the company intranet; what it solves is access for people—working from home, connecting to the office while traveling, one device at a time.
- Multi-site networking: the model is “network merging with network.” Headquarters has one network and a branch store has another; networking devices merge the two entire networks into a single logical large LAN: the branch’s POS terminals can reach the HQ server directly, HQ can directly access the branch’s cameras, and every device on both sides is visible to the other, just as if they were really in the same office.
Think of it as a phone analogy: an ordinary VPN is “handing everyone a mobile phone, and whoever wants to talk dials”; multi-site networking is “wiring the intercom systems of two rooms straight together, so everyone in the room can simply speak.”
2. Comparing Store Scenarios One by One: Why a VPN Always Falls a Bit Short
| The store’s real requirement | How an ordinary VPN performs | How multi-site networking performs |
|---|---|---|
| The branch POS system connects to the HQ database in real time | A POS terminal can’t dial a VPN by itself; every device needs its own client installed and maintained separately | Place one networking terminal at the branch and every device in the store is directly on the HQ network, with zero configuration on the POS terminals |
| The store’s broadband has no public IP address (which is now basically the norm) | The server side needs a public address to accept dial-ins; without one you have to rent a cloud server as a relay | No public IP required—both sides connect even behind NAT (see this article for how it works) |
| HQ centrally views surveillance from every store | Cameras and NVRs can’t dial a VPN, so you have to expose ports some other way, which carries major security risks | The NVR is accessed by HQ at its original LAN address (see the surveillance article for how) |
| It has to recover by itself after a disconnection, and no one at the store is technical | A dropped connection has to be re-dialed; after a router reboot or IP change the configuration may stop working, and someone has to keep an eye on it | Automatic reconnection within seconds, and automatic fallback to a cloud relay when a direct path fails—no one needs to look after it (see the stability article for a breakdown) |
| Opening a third or fifth store | Every new store means redoing the configuration and accounts all over again | A new store only needs one terminal powered on and registered to join the network, managed centrally from the console |
3. So Does That Make a VPN Useless? No
There is one case where an ordinary VPN is actually the better fit: only one or two people occasionally need a remote connection, and there is no store-to-store requirement. For example, if the owner alone wants to connect to an office computer from home and glance at a report, dialing a VPN or installing a remote desktop tool is enough—networking is overkill.
But if any one of the following applies, you should consider multi-site networking rather than a VPN:
- Two or more stores that need to access each other (any one of POS, inventory, or surveillance);
- What needs to be networked isn’t “people” but “devices”—POS terminals, cameras, NVRs, printers; these devices can’t dial in by themselves;
- The store’s broadband has no public IP address;
- There is no dedicated network person at the store, so no one can fix it when it goes down.
4. On Security, Where Do the Two Differ?
An ordinary VPN’s transmission is itself encrypted—that’s fine; the problem lies in how it is used: to make branch devices reachable, the common practice is port forwarding—exposing the ports of POS systems and cameras directly to the public internet. That is like leaving the door out in the open and then hoping the lock holds; internet-wide scanners knock on such doors 24 hours a day (the specific risks are covered in the NAS/ERP security article).
Next-generation networking takes a zero-exposure approach on the public internet: no port forwarding, traffic travels encrypted over direct P2P connections, falling back to a cloud relay only when a direct path fails, and there is no entry point on the public internet to attack. Member devices are authorized by account, and when an employee leaves, removing them in the console takes effect immediately.
5. How to Verify That Networking Fits Your Business
Don’t take anyone’s word for it—test it yourself: the Yuxinan free trial is RMB 0 forever, activated on registration, and includes a quota of 2 terminals (the quota includes hardware)—exactly “headquarters plus one branch.” Plug ordinary broadband into both sides, without touching the router or applying for a public IP, and if the branch’s POS terminal can reach the HQ server within ten minutes, that proves this approach works on your network. Once it runs, scale up by number of stores; the boundary between the free and paid editions is in this article, the full cost breakdown for multiple stores is in the chain-store networking cost article, and the six pricing tiers are published on the official website year-round.
FAQ
Q: Does the built-in VPN feature on a router count as networking?
A: The VPN server feature on home and entry-level routers is still the “point joining a network” model—others dial in. Some business routers support “site-to-site” interconnection, which conceptually is networking; it just has a high configuration barrier, requires a public IP, and needs someone knowledgeable to maintain. Next-generation networking has turned all of that into plug-in-and-go.
Q: My VPN is working fine—do I need to switch?
A: It depends on the use case. If it is just a few people working remotely, there is no need to switch. But if you are maintaining a setup where “every POS terminal needs a client installed and every store needs separate configuration,” then you are using a VPN to do the job of networking, and the more stores you have, the more burdensome it gets.
Q: After networking is set up, can employees still work from home at the same time?
A: Yes. Networking platforms generally also provide personal clients: whole-network interconnection in stores uses terminal devices, while personal phones and computers install a client with accounts issued per person—one system covers both needs.
Q: Is there a speed difference between networking and a VPN?
A: Both use encrypted transmission; speed depends on the path taken. With direct P2P, traffic runs between the two points and is limited by the broadband at each end; when going through a relay, bandwidth depends on the plan. For small-packet workloads like POS and inventory, either method is more than sufficient.
Prices and bandwidth for the Yuxinan free and paid editions are subject to the pages published on its official website as of October 2026.
