Network infrastructure services, built around your requirements.

Network infrastructure services and SD-WAN design for manufacturing plants and multi-site businesses in India. Firewalls in high availability, WAN links that fail over on their own, virtualization clusters that survive a node, storage that replicates offsite. We don't sell hardware or tools. We engineer the design, then specify whatever fits your requirement and budget, and you own every diagram and configuration.

Scope

What we design, build and run.

FIREWALLS

HA firewall management

Firewalls in high-availability pairs, with UTM features where they earn their keep. Intrusion detection and prevention, traffic shaping, VLAN isolation and automated, encrypted configuration backups.

WAN

SD-WAN & multi-WAN

Leased line, fibre and 4G/5G in one gateway group. Policy-based routing keeps ERP, CAD sync and voice on the committed link; failover in under three seconds.

COMPUTE

Virtualisation clusters

High availability for remote-desktop, ERP and accounting servers, tuned disk and network I/O, and deduplicated, client-side-encrypted backups.

STORAGE

Storage & replication

RAID 6 tiers, SSD read/write cache, metadata pinning, and snapshot replication across the site mesh and to immutable cloud storage.

Licensing changes

Vendor licensing changed. Your options didn't shrink.

Recent licensing changes in commercial virtualisation have turned hypervisors into a budget line nobody planned for. We run mixed estates today, and we migrate workloads when it makes sense, not on a vendor's timetable.

  • High-availability clusters with deduplicated, encrypted backups
  • Existing platforms kept where they still earn their keep, with image-level protection
  • Licensing overhead savings estimated at 40–60% versus proprietary stacks

Proposal

Scoped per environment.

A three-node cluster and a single storage box are different jobs. After the engineering audit you get a tailored proposal for exactly what you run.

Do we have to replace our current virtualisation platform?

No. Many estates run best as a hybrid for a while. We'll show you the cost and risk of each path and let you decide.

Can you work with the firewalls we already own?

Yes. We run mixed-vendor firewall estates in production. We'll tell you honestly when an existing appliance is fine and when it's a liability. We don't sell hardware, so we have no reason to push a replacement.

What does "HA" actually mean in your designs?

A specific failure — a node, a firewall, a WAN link — doesn't take the service down. Every design states which failures it tolerates and which it doesn't.

Do you also handle remote access?

Yes. See Secure Remote Access: VPN only from approved devices, with every user signing in against Active Directory.

Who owns the configuration?

You do. Diagrams, runbooks and configuration backups are part of the deliverable.

What is SD-WAN and does a plant need it?

SD-WAN steers traffic across several internet or leased-line links by application priority. Plants with more than one site or more than one link usually benefit; single-site plants may only need multi-WAN failover.

How does leased line failover work?

The firewall watches each link; when the leased line drops, traffic moves to fibre broadband or 4G/5G within seconds, with ERP, CAD and voice prioritised. See our Labs note on multi-WAN failover.
