The conference room disconnect nightmare Last Wednesday afternoon, a partner at a law firm in Tuanjiehu walked out of a third-floor meeting room with a MacBook, taking a conference call on the move. At the corridor corner, the Wi-Fi signal dropped for a full six seconds—the person on the other end thought he had hung…
The “evolution” of phishing attacks: why traditional defenses are failing. Before 2019, phishing emails were fairly easy to spot: grammar errors, unknown senders, .exe attachments. For most enterprise mail administrators, a spam filter alone was enough to block the bulk of attacks. But after 2024, attackers have learned enterprise defense playbooks inside out. They no…
Last winter, the owner of an auto-parts mold company in Shunyi came to me. He said his team of about twenty people was using a hand-assembled PC as a file server.

Traditional VPNs rely on usernames and passwords plus static certificates, and once authentication passes, the user gets full network permissions. That “verify once, allow forever” model already looks quite dangerous in 2024. I have seen more than one company’s VPN taken down by credential-stuffing attacks, with the…
Choosing a remote work solution for SMBs: traditional VPNs carry serious risk, while ZeroTier/Tailscale are unstable and non-compliant in China. A domestic zero trust SDP is the new answer for 2026. Using sTrust as an example, this article explains the side-by-side comparison, the 5-minute deployment process, pricing, and FAQs.
The remote access paradigm shift: VPN is on its way out. Last month, during a routine inspection at a design firm in Wangjing, their IT lead Lao Zhou vented to me: “We’ve been using that VPN for nearly eight years. With more and more staff working from home, opening a single design file takes half…
Start by understanding the operating conditions: the essential difference between online and standby UPS. Last winter I visited a client’s server room for an inspection and found they had equipped their core database server with a standby UPS. The boss said confidently, “As long as there’s a UPS, it’s fine.” I asked whether he knew…
