Sikka Broadband - The Best Internet Service Provider in Lucknow.

Understand the service

What is SD-WAN, in plain words?

If your business runs from more than one location — branches, stores, clinics, warehouses — those sites need to talk to each other and to your applications. Traditionally, that meant expensive dedicated lines to every site, a router at each office configured by hand, and a separate firewall bolted on top. Every change meant an engineer visit. Every link failure meant downtime.

SD-WAN (Software-Defined Wide Area Network) replaces that rigid setup with an intelligent one. Instead of depending on a single costly link, each site uses whatever connectivity is available — fiber broadband, a leased line, even 4G — and software decides, in real time, which traffic goes over which link.

Your billing software gets the most reliable path. Video calls get the lowest-latency path. Bulk downloads get the cheapest path. And if any link fails, traffic shifts to another within seconds, automatically — your team may never even notice.

All of it is controlled from one central dashboard, so your entire multi-city network is managed the way you'd manage a single office.

How it works

From many links to one intelligent network

Deployment is simple — most sites are live the same day the device is plugged in.

Connect any links you have

A compact SD-WAN device is installed at each site. It accepts fiber broadband, leased line and 4G/LTE together — including your existing connections. No rip-and-replace.

Set your policies once, centrally

From one cloud dashboard, define what matters: billing app first, video calls prioritised, social media limited. Policies push to every branch instantly — no engineer visits.

Traffic steers itself

The network continuously measures every link for speed, latency and packet loss, and routes each application over the best path. A link fails? Traffic fails over in seconds.

Capabilities

Everything your enterprise WAN should do

One managed service covering connectivity, intelligence, security and visibility.

Application-aware routing

The network recognises your applications — ERP, VoIP, video, SaaS — and sends each one over the path that suits it best, in real time.

Instant link failover

Fiber, leased line and 4G work as one. If a link degrades or drops, sessions move to a healthy path within seconds — calls and transactions stay alive.

Central management dashboard

See every site, link and application on one screen. Change a policy once and it applies across your whole network in minutes.

Zero-touch branch rollout

Opening a new branch? Ship the device, plug it in, and it configures itself from the central controller. New sites go live in hours, not weeks.

QoS for voice & video

Guaranteed bandwidth and priority for the traffic your business runs on — crystal-clear calls and stable video meetings even at peak hours.

Cloud on-ramp

Optimised, direct paths to Microsoft 365, Google Workspace and your cloud-hosted ERP — no more hair-pinning all traffic through head office.

Built-in security

One box for your network and your firewall

With Sikka SD-WAN, security isn't a separate appliance, a separate vendor and a separate bill. Every SD-WAN device ships with enterprise-grade protection built in, and security policies are controlled centrally — so every branch is protected the same way, updated at the same moment, with less hardware to fail and less downtime to manage.

FW

Stateful firewall in the same box

Full traffic inspection at every site — no separate firewall appliance to buy, rack or maintain.

WF

Web filtering

Block malicious, inappropriate or non-work sites by category, per branch or per user group.

ID

Intrusion detection & prevention (IDS/IPS)

Known attack patterns are detected and blocked automatically before they reach your systems.

VPN

Encrypted site-to-site tunnels

All branch-to-branch and branch-to-HQ traffic travels inside encrypted tunnels, even over ordinary broadband.

Why switch

Traditional WAN vs Sikka SD-WAN

Most enterprises still pay MPLS prices for a network that's harder to manage and slower to change. Here's the difference side by side.

Aspect	Traditional WAN / MPLS	Sikka SD-WAN
Cost	Expensive dedicated circuits at every site	Uses affordable fiber broadband + leased line + 4G together — typically 40–60% lower total cost
Reliability	One link per site; link fails, branch goes dark	Multiple links per site with automatic failover in seconds
Cloud performance	All traffic routed via head office, adding delay to SaaS & cloud apps	Direct, optimised breakout to cloud applications from every branch
Security	Separate firewall hardware and vendor at each site	Firewall, web filtering and IDS/IPS built into the same box, managed centrally
New branch rollout	Weeks of circuit provisioning and on-site configuration	Zero-touch: plug in the device, live within hours
Visibility & control	Per-router CLI changes, little application visibility	One dashboard — every site, link and app, with policies pushed in minutes

Who uses it

Built for businesses that can't afford downtime

Retail chains & showrooms POS uptime

Keep billing counters, POS machines and inventory systems online across every outlet. If broadband drops at a store, 4G takes over before the next bill is printed.

Banks, NBFCs & co-operatives Secure

Encrypted, policy-controlled connectivity between branches and the core banking system, with built-in intrusion prevention and full audit visibility.

Hospitals, labs & clinics Always-on

HIS, PACS and diagnostic systems stay connected across campuses. Prioritise critical applications so reports and records are never stuck behind bulk traffic.

Schools, colleges & coaching Filtered

Connect multiple campuses on one managed network with category-based web filtering — safe browsing for students, full control for administrators.

Corporate & back offices Cloud-first

Smooth Microsoft 365, video conferencing and cloud ERP across all offices, with voice and video prioritised over everything else.

Warehouses & logistics Rapid rollout

Bring new godowns and hubs online in hours with zero-touch devices, and track every site's connectivity from one dashboard.

FAQs

Common questions about SD-WAN

Do I need to replace my existing internet connections?

No. Sikka SD-WAN works with the links you already have — broadband, leased line or 4G, even from other providers. The SD-WAN device combines them into one intelligent network. Most customers do add a Sikka fiber link for performance, but it's not mandatory to start.

Is SD-WAN a replacement for MPLS?

For most businesses, yes. SD-WAN delivers equal or better reliability using multiple affordable links instead of one expensive circuit, with far better cloud performance. Some enterprises run SD-WAN alongside an existing MPLS circuit during transition — that works too.

How long does deployment take?

Once links are in place, a typical site goes live the same day. New branches use zero-touch provisioning — the device configures itself when plugged in, so multi-site rollouts take days, not months.

What happens when an internet link fails?

Traffic automatically shifts to the next available link within seconds. Active sessions — including voice calls and payment transactions — are preserved wherever possible, and you're alerted from the central dashboard.

Do I still need a separate firewall?

No. Every Sikka SD-WAN device includes a stateful firewall, web filtering and intrusion detection/prevention in the same box, with security policies managed centrally across all your sites.

Can I manage the network myself?

Yes — you get access to the central dashboard for full visibility and control. Or leave it to us: Sikka offers fully managed SD-WAN, monitored round-the-clock from our Lucknow NOC.
