Pick what you need.

Security monitoring

Every computer watched around the clock for ransomware, dodgy attachments and break-in attempts. The industry calls this EDR

Looking after your computers

Updates, monitoring and remote fixes, so problems get sorted before they stop your day. The industry calls this RMM

Help when something breaks

New laptops, printers, Wi-Fi, email accounts, the lot. You email me and you get me.

Networks, servers & file storage

Internet, Wi-Fi, a shared drive everyone works from, and backups that get tested.

Websites & online tools

The site your customers see, and anything they book or order through. Yours to keep.

Software built for how you work

Scheduling and dispatching jobs, quoting, invoicing, tracking stock — made to fit.

Private AI, running on your own hardware

An assistant that reads your documents and drafts your paperwork — without any of it leaving the building.

  edr-platform       › self-built EDR + email gateway  [hosted in Canada]
  private-cloud      › files, VPN, backups on my own hardware
  llm-runtime        › self-hosted models, 7B–14B, air-gapped option
  web-frontends      › client sites + portals, hand-coded

$ uptime --since
  first box racked years ago. rebuilt more times than I'd admit.
  still running.

drwxr-x--- security/ what's actually running on your endpoints ▸

1,200+ detection rules in production, Sigma-based
23,000+ threat indicators, refreshed every 6 hours from 5 live feeds
Behavioural detection — process lineage, credential access, mass-encryption patterns; no prior signature required
Tamper-evident audit log, Canadian-hosted, per-tenant isolated
Secure email gateway in front of the mailbox, not bolted on after

drwxr-xr-x ai/ how the private models are actually kept safe ▸

Self-hosted 7B–14B models on local hardware — prompts and documents never leave the network
Read-only first. The agent queries and drafts; it changes nothing by default
Approval gate on every write and every outbound email
Scoped, least-privilege database credentials — never a shared admin login
Vendor-agnostic: self-hosted, Claude or OpenAI, your call

drwxr-xr-x infrastructure/ the layer everything else depends on ▸

AD / Entra ID, hybrid identity, group policy, tiered admin separation
VLAN segmentation, Wi-Fi design, point-to-point links between sites
WireGuard site-to-site and remote access — admin services off the public internet entirely
Versioned, encrypted, off-site backups — and restores actually tested
Everything documented and reproducible, so your team can own it
