Enterprise Network & Security Infrastructure Solutions
Build a more agile, secure, and resilient enterprise network.
Unify connectivity, security, and operations across branches, campuses, data centers, clouds, and remote users.
Multi-vendor engineering · From architecture to continuous operations
The enterprise network has changed
Locations, clouds, users, and applications now depend on one another. Fragmented connectivity, inconsistent policy, and limited visibility turn infrastructure complexity into operational risk.
Branches & campuses
Cross-site connectivity and consistent policy
Cloud & data centers
Access to critical applications and data
Internet & multiple links
Bandwidth, quality, and path selection
Remote users
Reliable, controlled enterprise access
One infrastructure lifecycle
Not three disconnected products, but one way of designing, delivering, and operating enterprise infrastructure.
CONNECT
01Connect headquarters, branches, clouds, data centers, internet access, and remote users—then steer applications over the right path.
SECURE
02Bring access, policy, and protection into the connectivity design instead of managing network and security in isolation.
OPTIMIZE
03Turn availability, SLA, and performance signals into alerting, troubleshooting, technical support, and ongoing optimization.
Choose your starting point
Start with the problem that matters now, then connect networking, security, and operations through one architecture.
Intelligent connectivity
01Move beyond traditional WAN with application awareness, centralized policy, intelligent routing, and operational visibility.
Modernize the distributed WAN
Secure enterprise connectivity
02Unify connectivity and protection across branches, campuses, clouds, data centers, internet access, and remote users.
Converge network, security, and cloud
Continuous operations
03Continuously observe networks, links, bandwidth, SLA, and performance to support stable operations.
Improve visibility and response
WHY ZHANDIAN
Enterprise networking, security, SD-WAN, and operations expertise applied from assessment and architecture through delivery and support.
Technology ecosystem experience
01
Begin with business locations, applications, links, and security requirements.
02
Integrate network and security environments within verified technical boundaries.
03
Carry monitoring, troubleshooting, support, and optimization into the operating lifecycle.
Featured solution · SD-WAN
Bring connectivity, application awareness, intelligent routing, SLA, security policy, visibility, and daily operations into one enterprise WAN architecture.
Use internet, MPLS, 4G, and 5G links through one WAN architecture.
Identify important applications and align paths with business requirements.
Select a better path using link quality and SLA conditions.
Centralize network and security policy instead of configuring every branch in isolation.
Observe link, application, and SLA state to support faster diagnosis.
Use monitoring, alerting, troubleshooting, and optimization to sustain performance.
Application policy combines with link quality and SLA state to direct business traffic over a more suitable connection.
Secure enterprise connectivity
Connectivity and protection should not be separate conversations. Design access, policy, and security across the environments where applications and users operate.
Create dependable, controlled connections across distributed locations and critical environments.
Coordinate access, security policy, and network architecture to reduce management gaps.
Plan connectivity and protection boundaries around critical application and data access.
Operations that continue after deployment
More than device monitoring: continuously observe the signals that affect network operations, then support analysis, troubleshooting, and performance improvement.
24×7×365
01
Observe network, link, bandwidth, SLA, and performance state continuously.
02
Use alerts and operational context to assess impact and likely causes.
03
Provide remote technical support, troubleshooting, and incident coordination.
04
Use trends and operating evidence to improve network quality and policy over time.
Operational signals under continuous observation
Built for distributed enterprises
Every enterprise has a different mix of locations, applications, and operating constraints. Start with the operating model—not a device list.
01
Connect headquarters, plants, campuses, data centers, and cloud workloads.
02
Scale branch connectivity and centralized operations across large location estates.
03
Manage distributed sites, multiple links, and critical application experience consistently.
04
Coordinate on-premises infrastructure, cloud, internet access, and remote users.
Next step
Bring your current topology, migration objective, reliability issue, or security requirement. A useful conversation can start there.
