Introduction: Why SMBs Need Professional Firewall Configuration Even More As digital transformation accelerates, cybersecurity is no longer a topic reserved for large enterprises. SMBs face increasingly complex cyber threats as well—ransomware, DDoS attacks, and data breaches keep emerging. Yet many SMBs, constrained by limited budgets, often overlook professional firewall configuration and run on default rules…
Starting with three clients that got hit — In Q1 this year we handled three ransomware incidents: one through RDP brute force, one through a phishing email, and one where a backdoor was planted during a vendor’s remote maintenance session. The attack paths in all three cases can almost be strung together into a textbook…
Introduction: Why SMEs Need to Master Firewall Configuration In today’s digital era, network security has become part of the infrastructure of business operations. For small and medium-sized enterprises, building a secure and reliable IT environment within a limited budget is a real problem they must face. As the first line of defense for an enterprise…
Stuttering office video conferences? It may be a network-layer issue. A single 1080p meeting on Zoom or Tencent Meeting needs 2–3 Mbps, yet many meeting rooms have bandwidth to spare while the video still looks like a blurry mess. The problem usually isn’t whether there’s enough bandwidth, but whether the network is stable and properly…
Entering 2026, digital transformation is no longer a question of whether companies “should do it,” but a question of survival: how to do it, and how fast. From government work reports to industry white papers, “new quality productive forces” and “digital-intelligence integration” have become high-frequency keywords. Yet for the small and medium-sized enterprises that account…
The Real Impact of China’s Data Security Law on IT Procurement at SMEs In September 2021, China’s Data Security Law officially took effect. Three years on, many SME owners in Beijing have found themselves facing an awkward reality: compliance checklists keep getting longer, while procurement decisions have only become harder. Choosing an IT vendor used…
As enterprise digitalization accelerates, IT operations is no longer simply about “fixing computers and getting the network up.” In 2026, with the deep convergence of artificial intelligence, edge computing, and cloud-native technologies, enterprise IT operations is undergoing a profound shift from reactive “firefighting” to preventive management. This article examines the current trends shaping the IT…
Let’s start with a real case: a 200-square-meter office of an advertising agency deployed six APs. The meeting room showed full signal bars, yet browsing was painfully slow — the most typical beginner’s setup I have ever seen. The client assumed more APs meant better coverage, but the 2.4 GHz and 5 GHz channels all…
A firewall is not as simple as “adding one more rule.” Last week I visited an education software customer in Huilongguan. On site, I found their firewall policy list had more than 370 rules, of which fewer than 80 were probably actually in use. When I asked why there were so many, the ops engineer…
Grading is not about filling in forms — it is a “health check report” that maps your real assets. After more than a decade in IT operations in Beijing, I have seen too many SMEs misunderstand “Multi-Level Protection Scheme 2.0” (China’s MLPS 2.0, hereinafter “MLPS 2.0”). Many owners treat it as an administrative task of…
When “fixing computers” is no longer the endpoint of IT services: a quiet revolution driven by subscriptions. In the first quarter of 2026, in the office buildings of Yizhuang, Beijing, the air seems to hold a little less of the usual firefighting anxiety. As a fifteen-year veteran of this industry, I have witnessed firsthand how,…
When AI is no longer just a slogan, the “hidden costs” of enterprise IT are being redefined. Every year, when Gartner releases its technology trends report, there is always a round of noise. For many large groups, these trends mean budgets in the tens of millions and a complete architectural transformation. But for the small…
