Why Sydney businesses call us
The IT problems we fix every day.
These are the most common IT issues Sydney SMBs face — and why they keep happening without a proactive IT partner.
Slow computers slowing down the whole team
Why it happens
Outdated drivers, background processes, and deferred maintenance accumulate over time.
How we fix it
We remotely tune endpoints, clear bloat, and push patches — average performance improvement felt within 48 hours.
Microsoft 365 emails going to spam or not sending
Why it happens
Missing SPF/DKIM/DMARC records, shared IP reputation issues, or misconfigured Exchange rules.
How we fix it
We audit your M365 tenant health, fix DNS email authentication, and monitor deliverability on an ongoing basis.
Staff can't access files when working from home
Why it happens
VPN misconfiguration, SharePoint permission errors, or Conditional Access policies blocking sign-in.
How we fix it
We configure Entra ID conditional access and test remote access before staff hit issues — not after.
New staff take days to get set up with IT
Why it happens
No onboarding runbook, manual account creation, and untracked software licences.
How we fix it
We build a provisioning workflow — new hire request to fully configured laptop in under 4 hours.
Printers stop working with every Windows update
Why it happens
Driver compatibility issues between Windows Update and shared network printers.
How we fix it
We manage printer drivers centrally via Intune, ensuring updates don't break print queues across the office.
No idea if your data is actually backed up
Why it happens
Backup jobs run silently and aren't tested — until recovery is needed and they fail.
How we fix it
We configure automated cloud backup with daily integrity checks and quarterly tested restores — not just assumed restores.
Unknown devices appearing on your office network
Why it happens
No network segmentation, weak Wi-Fi password hygiene, and unmonitored DHCP leases.
How we fix it
We segment your network with VLANs, deploy NAC policies, and set up monitoring alerts for unknown devices.
Phishing emails reaching staff despite spam filters
Why it happens
Default Microsoft Defender settings are often insufficient without hardened anti-phishing policies.
How we fix it
We configure Defender for Office 365 with custom impersonation rules and run simulated phishing tests for staff.
No one knows what software licences you're paying for
Why it happens
Licences accumulate as staff join and leave, with no centralised asset register.
How we fix it
We audit your SaaS and M365 licence usage quarterly and reclaim or reassign unused seats — typically saving $200–$800/month for a 20-person business.
