Understand the Site
We ask about the building, the users, the applications and the deadline before we ask about brands. Where a site is already running, we audit what is installed and what is about to lapse.
What we do, how we do it, and the hardware each service is built on.

Overview
We Specify It, Supply It and Keep It Running
Mercury Infosys is a UK reseller and distributor of enterprise networking hardware, but customers come back because of what happens around the box: honest sizing, licences quoted with the hardware, equipment delivered configured, and renewals tracked so nothing lapses by accident.
Size and Quote
Two options come back: the right fit for today and a headroom option. Both are quoted with licences, cables and transceivers included, so nothing is billed after the order.
Configure and Deliver
Equipment arrives configured rather than boxed — policies applied, HA pairs tested in our workshop, and the running configuration documented for your own team.
Support and Renew
We stay on the estate: expiry alerts, firmware guidance, spares and engineering cover, so the next refresh is planned rather than urgent.

What We Do For Our Customers
Each service below links straight to the product ranges it is built on, so you can read the specification and the supply route side by side.
Network Design & Sizing
We start from your floor plan, user count and application load, then specify switching, routing and uplinks that still have headroom three years out. You get a bill of materials with port counts, PoE budget and transceivers listed — not a box model plucked from a price list.
Products for this service
Firewall & Security Deployment
Firewalls are sized on inspected throughput with SSL inspection switched on, not the headline firewall figure. We quote the appliance with the right protection bundle and support term, migrate your policy from the outgoing box, and test failover before go-live.
Products for this service
Wireless & Mobility
Coverage is designed from a proper survey — walls, ceilings, client density and the applications people actually run. We specify access points, controllers and PoE switching together, so the wireless and the cabling behind it are quoted as one job.
Products for this service
Phone Systems & Collaboration
Voice, video and conferencing kit supplied with the licensing and handsets your site needs, on a platform your existing cabling and PoE budget can carry. We can migrate an estate number by number rather than cutting a service over in one afternoon.
Products for this service
Licensing & Renewals
A lapsed subscription quietly turns a next-generation firewall into a plain router. We track serials and expiry dates across your estate, alert you 90 days out, price 12, 36 and 60 month terms side by side, and co-terminate everything onto one renewal date.
Products for this service
Power & Resilience
Racks that lose power lose the network. We size UPS capacity against the real load in the cabinet — switches, servers, cameras, phones — and quote rack-mount and tower units with the batteries, cabling and monitoring the installation needs.
Products for this service
Access Control & Surveillance
Door controllers, readers and cameras specified alongside the switching that powers them, on separate VLANs from day one so a camera never sits on the same network segment as a finance laptop.
Products for this service
Servers, Endpoints & Storage
Compute, laptops, desktops and backup hardware sourced across multiple vendors, so you can put one purchase order against a refresh that touches the server room, the comms cupboard and the desks.

Questions We Are Asked Most
Do you only supply hardware, or do you configure it too?
Both. Most customers ask us to supply and configure: policies applied, HA pairs built and failover tested, and the running configuration documented before the equipment reaches the rack. If you have your own engineers, we will ship it boxed and stay available for the questions.
Can you quote a mix of brands on one order?
Yes. A single purchase order can cover Cisco switching, Fortinet firewalls, Meraki wireless and APC power. We are an independent reseller, so we specify what suits the site rather than what one vendor wants to move.
Can you take over equipment we did not buy from you?
Yes. Send the serial numbers and we will confirm the licence position, expiry dates and firmware state, then quote the renewal or refresh — including co-terminating a scattered estate onto one renewal date.
How quickly can a solution be delivered in the UK?
Mainstream switches, firewalls and access points usually ship within one to three working days. Longer lead times are flagged on the quote rather than after the order, and we will tell you honestly if a cheaper, faster alternative covers the same requirement.
