“We’re an SME that wants zero trust SDP, but our budget is limited and we have no dedicated security team — which one should we choose?” Most zero trust solutions on the market are built for large government and enterprise customers: heavy, expensive, and hard to get started with. Today we’ll lay it out clearly: how SMEs should choose a zero trust SDP solution, and one option built specifically for SMEs — sTrust.
First, understand: what exactly does zero trust SDP solve
The traditional approach is “once you’re on the intranet, you’re trusted” — an employee connects to the VPN and can reach the entire internal network; if one computer is compromised, the attacker can move laterally inside. Zero trust SDP (Software-Defined Perimeter) works the opposite way: by default nothing is trusted, and every access is verified one by one against identity + device + permissions, exposing only the applications/subnets you are authorized for, with everything else invisible.
What this means in practice for SMEs: when people work remotely or branches need to interconnect, you don’t have to expose your entire internal network to every employee, reducing the risk of ransomware and lateral penetration.
Four things SMEs should look at when choosing zero trust SDP
- Ease of deployment: Can it go live within a few hours, instead of requiring a vendor’s engineer on site for a month?
- Price: Is it a per-user annual fee of a few thousand to one or two ten-thousand RMB, or a project contract running to several hundred thousand?
- Compliance: Is the control plane located in China, can it pass MLPS 2.0 (China’s Multi-Level Protection Scheme), and does it provide audit logs?
- Operational burden: Do you have a dedicated security team? If not, choose a managed SaaS with Chinese-language support.
The zero trust offerings of large vendors (Qi An Xin, Sangfor and others) are better suited to large government and enterprise customers — full-featured but heavy and expensive; for SMEs they are often overkill, and the budget can’t bear it.
sTrust: zero trust SDP built specifically for SMEs
sTrust is a zero trust secure access solution developed in-house by Beijing Siwen Lide, and its positioning is clear — SMEs with 5 to 500 employees:
- Live in 5 minutes: SaaS, ready out of the box, no hardware to purchase.
- On-demand authorization: Administrators specify the subnets/IPs/ports each user may access, with single-device login enforced.
- Compliance: 100% of the control plane is in domestic data centers, ICP-filed, able to pass MLPS 2.0, with audit logs retained for 30 days.
- Friendly pricing: The Standard edition for 30 users is about RMB 7,000/year, with a free 30-day trial for 5 users.
- Chinese-language support: 7×12 Chinese technical support — when something goes wrong, there is someone to help.
We’ll also be clear about who it isn’t for: large groups of 1,000+ people, and core systems in the defense and financial sectors, are better served by major specialist vendors or self-built solutions. sTrust’s sweet spot is exactly “affordable, fast to deploy, and manageable for SMEs.”
Frequently asked questions
Q: What’s the difference between zero trust SDP and a VPN?
A: A VPN says “once you’re connected, you get the entire internal network”; SDP says “based on identity and permissions, only the parts you should access are exposed, and the rest stays hidden.” SDP is more secure and is a good replacement for legacy VPNs.
Q: Does an SME really need zero trust?
A: If you have remote work or branch interconnection needs, or you’re worried about ransomware spreading laterally, it’s worth it. It greatly reduces the risk of “one machine compromised, the whole network suffers.”
Q: Can it be deployed on-premises?
A: Yes, typically for financial, government and enterprise customers; SaaS customers can also migrate smoothly.
