Enterprise Network Design & Deployment

From campus LAN to multi-site WAN architectures, we design and deploy enterprise networks that deliver predictable performance, built-in redundancy and security-first segmentation — optimized for your specific traffic patterns and growth plans.

Network Architecture Design

Three-tier and spine-leaf architectures designed for your specific scale — from single-site campuses to multi-city enterprise WANs with SD-WAN overlay.

Network Segmentation & VLANs

Micro-segmentation strategies that isolate critical systems — separating core banking, guest access, IoT devices and OT networks with policy-enforced boundaries.

Redundancy & High Availability

Active-active and active-passive failover designs with sub-second convergence. Dual ISP links, stacked switches and HSRP/VRRP configurations eliminate single points of failure.

QoS & Traffic Engineering

Quality of Service policies that prioritize business-critical applications — voice, video conferencing and real-time trading systems receive guaranteed bandwidth and latency.

Secure Access

Zero Trust & Secure Access

Modern enterprises need security that extends beyond the perimeter. Our Zero Trust Network Access solutions verify every user, device and application before granting access — regardless of location.

From VPN replacement to SASE architectures, we implement secure access solutions that enable productivity without compromising security.

ZTNA SASE MFA NAC PAM
01

Zero Trust Network Access (ZTNA)

Application-level access without exposing the network. Users connect only to authorized applications based on identity, device posture and context — replacing traditional VPNs with a more secure, granular approach.

Zscaler ZPA Palo Alto Prisma Fortinet ZTNA
02

Network Access Control (NAC)

Cisco ISE or FortiNAC-based solutions that enforce device compliance before granting network access. Automatically quarantine non-compliant devices and enforce security policies at the port level.

Common Questions

Frequently Asked Questions

If you have a question not answered here, our network engineers are available to provide a personalised consultation for your organization's specific infrastructure requirements.

Speak to an Engineer
Do you provide network design services or only deployment?

We provide end-to-end services — from initial site survey and network architecture design through procurement, deployment, testing and ongoing management. Our design process includes high-level and low-level design documents, bill of materials, implementation plan and test cases. We can also review and optimize existing network designs.

Which network equipment brands do you work with?

We are a multi-vendor partner with certifications from Cisco (Gold), Fortinet (Expert), HPE Aruba, Juniper, Palo Alto Networks, Sophos, Ruckus, CommScope and Panduit. We recommend equipment based on your specific requirements, existing environment and budget — not vendor bias.

Can you handle multi-site deployments across different cities?

Yes — we have deployed networks across 500+ sites in 30+ cities across India. We have regional project managers, local deployment teams and a centralized NOC that provides consistent quality regardless of location. For large rollouts, we use standardized templates and zero-touch provisioning to ensure consistency across all sites.

Do you provide structured cabling warranties?

Yes — all our structured cabling installations are backed by OEM system warranties from CommScope, Panduit or Molex (depending on the selected vendor). These are 25-year system performance warranties that cover the entire cabling infrastructure, not just individual components. Every installation includes certified Fluke test reports.

Can you integrate new infrastructure with our existing legacy network?

Absolutely. We specialize in brownfield deployments where new infrastructure must coexist with legacy equipment. We perform a thorough assessment of your existing environment, design integration strategies that maintain uptime during transition and provide a phased migration plan. Our engineers have extensive experience with mixed-vendor environments and legacy protocol support.
