Secure Access Service Edge (SASE) Solutions in Hong Kong
Secure Your Workforce Anywhere with Cloud-Based Security
As businesses increasingly adopt cloud applications and hybrid working, traditional office-based firewalls can no longer provide complete protection. Employees now access company resources from home, client offices, airports, hotels, and mobile devices.
A Secure Access Service Edge (SASE) solution delivers enterprise-grade security directly from the cloud, ensuring users, devices, and applications remain protected no matter where they work.
At TopOne Information Technology, we deploy and manage SASE solutions to help businesses build a modern Zero Trust security architecture without the complexity of traditional VPN infrastructure.
What is SASE?
Secure Access Service Edge (SASE) is a cloud-native cybersecurity architecture that combines networking and security services into a single platform.
Instead of forcing users to connect through the office firewall before accessing cloud applications, SASE authenticates every user and device first, then securely connects them to the applications they are authorized to use.
Every connection is continuously verified based on:
- User identity
- Device health
- Location
- Security policies
- Risk level
This Zero Trust approach significantly reduces cyber risks while providing faster and more reliable access to business applications.
Why Traditional Security is No Longer Enough
Traditional corporate networks were designed around the assumption that everyone worked inside the office.
Today, businesses rely on:
- Microsoft 365
- SharePoint Online
- OneDrive
- Teams
- Remote Desktop
- SaaS applications
- Hybrid work
- Mobile devices
- Multiple branch offices
Sending all traffic back through the office firewall creates:
- Slow VPN connections
- Poor Microsoft 365 performance
- Firewall bottlenecks
- Increased attack surface
- Complex firewall management
SASE moves security closer to users instead of forcing users to connect back to the office.
Key Features of our SASE Solution in Hong Kong
SSL/TLS Zero Trust Network Access (ZTNA)
Replace traditional VPN with secure application access.
Users only gain access to specific applications they are authorized to use instead of the entire corporate network.

Secure Web Gateway (SWG)
Protect employees while browsing the Internet.
Every web request is inspected before reaching the destination.

- URL filtering
- DNS filtering
- HTTPS inspection
- Web category blocking
Prevent users from visiting malicious or inappropriate websites before attacks happen.
Cloud Firewall as a Service (FWaaS)
Enterprise firewall protection delivered from the cloud.
Instead of relying only on office firewalls, Cloud firewall applies security policies at its global network edge.
Capabilities include:
- Layer 3–7 traffic inspection
