“We want to roll out zero trust remote access for our company — how do we choose among domestic solutions?” This has been one of the most frequently asked questions lately. The market ranges from major vendors such as Sangfor and QiAnXin to Tencent iOA and all kinds of SDP/ZTNA products — a pile of names, yet prices and positioning differ wildly. Today, with no hype and no bashing, we will explain clearly how to choose a domestic zero trust

“The printer won’t connect again.” “I hit print and nothing happens.” “It works for everyone else but not for me.” — The most annoying and most frequent IT complaint in the office is, nine times out of ten, the shared printer. It looks like a small thing, but when it jams up, no one gets any work done all morning. Today we’ll cover it thoroughly: where exactly shared printer connection failures and print errors get stuck, how to troubleshoot step

Employees use their own phones to receive work WeChat messages, sign into company systems on personal laptops, and revise proposals on a tablet while traveling — this kind of “bring your own device” (BYOD) is now everywhere. It is genuinely convenient, but the hidden risks are just as real: company data is scattered across a pile of personal devices — so what happens to that data when someone leaves, a phone is lost, or a device gets compromised? Today we

“My computer takes five minutes just to boot,” “the browser freezes the moment I open it,” “saving a spreadsheet spins forever” — almost every office PC that’s been in service for two or three years reaches this point. Many owners react by replacing the machines, and a batch of new ones runs into tens of thousands of yuan; others tough it out, while employees wait on their computers all day and productivity drains away in that spinning circle.

Employees traveling for business, working from home, or visiting client sites often need access to company internal systems, including OA, ERP, finance, and inventory management applications. How can you enable access from outside the office while maintaining security? Many companies simply expose these systems to the public internet and provide an external login address—one of the riskiest approaches. This article explains the real risks of exposing internal business systems, why port forwarding and a public address invite security incidents, and

“The office Wi-Fi is lagging again.” “The meeting room drops everyone as soon as it fills up.” “Walk a few steps away from the router and there’s no signal.” Almost every small or mid-sized company has heard these lines. Most people’s first reaction is “the broadband isn’t fast enough — add bandwidth,” and after the money is spent the problem stays exactly the same. Today we’ll lay out clearly what really causes slow, laggy office Wi-Fi with poor signal, why

Hiring an outsourcer to roll out a system, letting a vendor connect remotely for equipment maintenance, bringing in a freelancer for a temporary project… small and medium-sized businesses are putting “outsiders” onto their corporate network almost every day. Yet when it comes to these third-party personnel, what permissions they should be given, for how long, and whether the access channel is still open after they leave — many companies simply have no one managing any of it. Today we’ll spell

When your office network is slow or keeps dropping, don’t rush to reboot or buy more bandwidth. This guide shows you how to work from the outside in, isolate the common root causes (router, Wi-Fi, bandwidth, line, compromise), and build IT operations practices that keep SMB networks stable long term.

Collecting the laptop and badge at offboarding is far from enough. This guide explains which access rights must be revoked, why traditional methods always leave gaps, and how unified identity plus zero trust cuts off all remote access the same day an employee leaves.

With a headquarters plus branch offices, stores, and warehouses, how do you connect several networks into one secure, stable private network? A clear look at four options — dedicated lines, encrypted tunnel networking, zero trust remote access, and cloud relay — covering who each one suits, how to choose, what it costs, and the most hassle-free combination for small and medium businesses.
