Most IT support shops say they do cybersecurity. When you dig deeper, few have CISSP or CISA credentials, or staff with experience improving security for governments and Fortune 50 companies. ThreeShield brings that expertise to Calgary businesses of every size — and whoever answers the phone at 403-538-5053 actually knows what they're talking about.
Clinics, dental practices, pharmacy groups, and primary care networks need IT support that understands Alberta HIA, HIPAA for cross-border health tech, and PCI DSS for medical offices accepting card payments. ThreeShield's principal is a former auditor of Alberta Health Services.
Healthcare IT →CPA firms work with tight deadlines during month-end, year-end, and tax season. ThreeShield freezes changes during your critical periods and provides IT support that understands Caseware, TaxCycle, ProFile, and the specific security requirements of accounting practice management. ThreeShield's founder speaks at the CPA Banff Small Practitioner's Forum.
Accounting Firm IT →Calgary is the headquarters of Canada's energy sector. IT support for oil and gas operators, pipeline companies, and energy services firms requires understanding of OT/IT convergence, CER and AER requirements, NERC CIP for bulk electric operators, and Bill C-8 CCSPA for federally regulated pipelines.
Energy Sector Security →You don't need to be in a regulated industry to need proper IT security. Credit card agreements, cyber insurance, client contracts, and government procurement all require security controls that most SMBs don't know how to implement. ThreeShield can secure and manage what you already have, and help you grow without creating security debt.
Start a Conversation →Early-stage companies face pressure from investors, enterprise clients, and banks to demonstrate security controls. ThreeShield can rapidly assess and remediate your security posture, complete SOC 2 readiness assessments, set up M365 or Google Workspace securely, and prepare you for the security questionnaires that come with your first enterprise customer.
Lavawall® for Start-Ups →Many Calgary organizations have internal IT staff who are competent but overstretched — handling helpdesk, infrastructure, and security simultaneously. ThreeShield fills the Tier 3 security gap: CISSP/CISA expertise that supports your existing team on complex security questions, compliance requirements, and incidents they haven't seen before.
Tier 3 Augmentation →Conditional access policies, MFA enforcement, Defender configuration, Exchange Online Protection, SharePoint permissions, Teams security settings, and continuous monitoring via Lavawall® for unusual logins, forwarding rules, and account compromise indicators.
Automated patching across Windows, macOS, and Linux endpoints, plus over 7,533 third-party applications via Lavawall®. Patch compliance reporting for cyber insurance and compliance purposes. Endpoint Detection and Response (EDR) deployment and monitoring.
Firewall configuration review and management, wireless security, VPN configuration, network segmentation for compliance requirements (PCI DSS, NERC CIP), and monitoring for unusual network behaviour. IPMI and out-of-band management interface security — the gap most MSPs miss.
Backup architecture review, isolation testing (critical for ransomware resilience), quarterly restore simulations, and business continuity planning. ThreeShield verifies that backups actually work — not just that the backup job completes.
Annual security awareness training, phishing simulation testing, and combined compliance training that satisfies multiple frameworks in a single session. Staff who understand why security matters are your most reliable control.
Cyber insurance questionnaire completion, client security questionnaire responses, compliance gap assessments for any applicable framework, and monthly/quarterly reporting in plain language for management. ThreeShield handles the compliance paperwork so your team doesn't have to.
