Your virtual senior security team
The senior security team
behind your IT.
Strategy, audits, compliance, and hands-on Tier 3 support from CISSP/CISA-certified experts — connected to your environment through the Lavawall® platform we build ourselves. One relationship. One team that owns the outcome. Since 2006.
Start where you are
Three ways teams work with us
I run IT
Senior backup for your IT team
You handle the day-to-day. We're the senior security people you call when something's weird, an auditor shows up, or the insurance form asks a question you can't answer alone.
For lean IT teams →I run an MSP
White-label Tier 3, never a competitor
CISSP/CISA escalation under your brand, with written rules of engagement. We grew out of an MSP — we don't go around partners. Ever.
For MSPs & partners →I run a clinic or accounting firm
Managed IT for Calgary medical & accounting
Our only direct managed-IT practice: Calgary clinics and CPA firms that want IT, security, and HIA/CPA compliance handled by one accountable local team. Outside that niche, we refer you to a partner MSP.
For Calgary medical & accounting →Why one partner
Platform, audit, and support — from the same people.
Most organizations juggle a compliance platform, a consultant, an auditor, and a support provider — and nobody owns the overall outcome. ThreeShield delivers all four in one relationship, so findings actually get fixed.
Real audits, not checklist scans
CISA-led reviews using government and Fortune 50 methodology — typically 200+ findings where automated scans surface a handful.
Continuous visibility via Lavawall®
Patching, M365/Google breach detection, file monitoring, and GRC evidence — running all year, not just at audit time.
Hands-on remediation
We don't hand you a report and disappear. The team that found the problems fixes the critical ones with you.
Compliance that sticks
SOC 2, HIPAA, Alberta/BC HIA, PCI, NIST, CIS, CMMC, NERC CIP, CPA Canada — operationalized in your daily work, not binders on a shelf.
The platform behind the people
Powered by Lavawall®
We built Lavawall® because the tools we audited kept missing what mattered. It patches 7,500+ applications, watches Microsoft 365 and Google Workspace for breaches, monitors your files, and automates compliance evidence — with our senior team watching the results.
How we work
From first look to year-round security
1. Free assessment
Non-intrusive review: domain scan, M365 quick-check, insurance questionnaire review. Plain language for owners, full detail for your IT team. No obligation.
2. Visibility in hours
Lavawall® connects to endpoints, Microsoft 365, Google Workspace, and your domains — you see what we see.
3. Fix what matters
Deep audit if you need one; either way we prioritize and remediate the critical items with your team, not around them.
4. Stay strong year-round
Tier 3 escalations, compliance upkeep, and quarterly reviews — the platform watches continuously, and real people respond.
Client voices
Trusted from Main Street to Fortune 50
"They are hands on and proactive. Cyber security insurance providers have confirmed they have protected our business well. It's nice being able to sleep well at night."
"As Chief Compliance Officer of a payments entity, I have relied on ThreeShield to provide risk-based solutions that have satisfied regulators and business partners alike."
"In a short time, we accomplished what much larger companies still struggle to achieve — with minimal disruption to the engineering organization."
Organizations we've worked with
Common questions
Before you call
- We already have an MSP. Is this awkward?
- Not at all — we work with and through MSPs every day, and much of our work arrives via MSP partners. Our only direct managed-IT practice is Calgary medical clinics and accounting firms; every other managed-IT inquiry is referred to a partner. Lavawall® complements existing RMM and EDR stacks, and our rules of engagement are written down and public.
- How is this different from hiring a vCISO?
- A vCISO gives you strategy without execution. ThreeShield gives you strategy, the platform, audit execution, compliance delivery, and hands-on support — for less than a single senior hire.
- Do you only serve Calgary?
- On-site managed IT is focused on Alberta. Audits, compliance, and Lavawall®-powered augmentation are delivered across Canada, the US, and internationally.
