Five layers, plus the code that runs on them.

We cover the full lifecycle of your systems, and we build the business applications the market does not cover. Every engagement ends with written deliverables — not just an installation that works on handover day.

L1

Infrastructure

Design and modernise what everything else rests on: servers, network, storage, virtualisation.

What we do

  • Physical and virtual server architecture
  • Corporate LAN and Wi-Fi networks
  • NAS and storage arrays
  • Migration and consolidation of existing estates

What you receive

  • Target architecture diagram
  • Detailed costing, phase by phase
  • Operations documentation
L2

Cybersecurity

Reduce the attack surface before it gets used, then verify the reduction holds.

What we do

  • Security audits and penetration tests
  • Active Directory and endpoint hardening
  • EDR, MFA, network segmentation
  • User awareness sessions

What you receive

  • Audit report ranked by risk
  • Costed remediation plan
  • Follow-up review after three months
L3

Video surveillance and electronic security

See what happens, and be able to prove it on the day it matters.

What we do

  • Coverage study and camera placement
  • NVR and secure remote access
  • Access control and alarms
  • Maintenance of installations

What you receive

  • Annotated coverage plan
  • Quote for hardware and installation
  • Operator training
L4

Operations and managed services

Hand over part or all of your IT to a team that answers, with written commitments.

What we do

  • Monitoring and remote support
  • Patch and update management
  • User helpdesk
  • On-site interventions

What you receive

  • Contract with defined SLA
  • Monthly activity report
  • Asset inventory kept up to date
L5

Backup, disaster recovery and continuity

A backup that has never been restored is not a backup.

What we do

  • Veeam, NAS and replication
  • 3-2-1 strategy and offsite copy
  • Documented restore tests
  • Disaster recovery plan drafting

What you receive

  • Usable disaster recovery plan
  • Signed restore test record
  • Stated RTO and RPO

Business application development

Cross-cutting domain: a business application relies on all five layers, and must be backed up and secured like everything else.

When no off-the-shelf product matches the process, or when it costs more than the problem it solves.

What we do

  • Custom management applications (case tracking, stock, HR, invoicing)
  • Replacing spreadsheets and homemade databases that became unmanageable
  • Interfaces and automation between existing systems
  • Taking over and maintaining applications built by others

What you receive

  • Specification signed off before the first line of code
  • Source code handed to the client, with no lock-in to KANTBUS
  • Technical documentation and user guide
  • User training and migration of existing data

A need that spans several layers?

That is the usual case. We start with an assessment before proposing anything.
