Managed IT Services
End-to-end IT management for Brookfield offices — we handle monitoring, maintenance, patching, and helpdesk so your team focuses on their actual work. Proactive management means we catch problems during overnight scans rather than during your Monday morning standup. One flat monthly rate covers everything.
Cybersecurity
Every managed IT plan includes enterprise-grade cybersecurity — endpoint detection, email filtering, DNS protection, and multi-factor authentication. Brookfield businesses handling sensitive financial or healthcare data get compliance-ready security included, not bolted on as an expensive add-on.
Cloud & Microsoft 365
Microsoft 365 administration, license optimization, Teams configuration, SharePoint management, and Entra ID for Brookfield businesses running hybrid or fully cloud environments. We handle migrations, day-to-day management, and user support so your cloud investment actually delivers.
Network Management
Managed networking for Brookfield corporate offices — firewall management, switch configuration, Wi-Fi optimization, and VPN access for remote workers. We design networks for multi-suite corporate environments like Bishop's Woods and Brookfield Lakes where reliable connectivity is non-negotiable.
VoIP Phone Services
Cloud-hosted business phone systems for Brookfield offices replacing legacy PBX hardware. Auto-attendants, call routing, voicemail-to-email, and mobile integration. VoIP management is included in your managed IT plan — no separate vendor to deal with.
IT Compliance
Compliance-aligned IT management for Brookfield's financial services firms, healthcare practices, and insurance agencies. We configure systems to meet HIPAA, PCI-DSS, SOX, and FINRA requirements and maintain documentation for audit readiness.

Quick IT Tips
Practical advice for Brookfield businesses — whether you work with us or not.
- •Ask your current IT provider for a list of every device on your network. If they can not produce one quickly, that is a sign your infrastructure is not being properly managed.
- •Brookfield offices in multi-tenant buildings should verify their firewall separates their network from neighboring tenants. Shared building networks without proper segmentation create security exposure.
- •Review your Microsoft 365 license assignments quarterly. Most Brookfield businesses are paying for licenses assigned to former employees or unused mailboxes.
- •If your managed IT provider only contacts you when something breaks, you do not have managed IT — you have break-fix with a monthly bill. Proactive management means regular reviews and strategic planning.
- •Back up your data to a location outside your Brookfield office. Local-only backups do not protect against theft, fire, or ransomware that encrypts everything on your network.
