CPA Canada's Cybersecurity Framework defines governance, risk management, protection, detection, and response obligations for the accounting profession. ThreeShield's CISSP/CISA team with extensive accounting firm implementation experience including Caseware, CaseView, and tax software integrations.
CPA Canada's framework mirrors the NIST CSF structure with accounting-profession-specific context and examples. The five pillars align with how accounting firms manage risk and client data.
Board and partner oversight of cyber risk. Defined cybersecurity accountabilities. Cybersecurity strategy aligned with firm risk appetite and client obligations.
Annual cybersecurity risk assessment. Vendor and supply chain risk. Third-party access to client data and engagement platforms.
Access controls, MFA, encryption, patch management, and endpoint protection. Client data isolation and segmentation. Secure remote access for hybrid teams.
Monitoring for anomalous access to client files, unusual authentication patterns, and data exfiltration indicators. Lavawall® provides continuous M365 and endpoint monitoring.
Incident response plan covering breach notification to affected clients and applicable regulators. Tested recovery capability. Professional liability insurance alignment.
ThreeShield has worked on security engagements with major Canadian accounting firms using Caseware, TaxCycle, ProFile, and related platforms. We understand the client data handling requirements, regulatory expectations, and reputational stakes of the accounting profession from the inside.
The framework is guidance rather than mandatory regulation - CPA Canada publishes it to help member firms manage risk. However, provincial CPA regulatory bodies, professional liability insurers, and major enterprise clients increasingly expect accounting firms to demonstrate framework alignment. Non-compliance is a reputational and professional liability risk.
CPA firms handle significant volumes of personal financial information, placing them firmly within PIPEDA's scope and, for firms with Alberta clients, Alberta's PIPA. The CPA Canada framework's protection and response pillars directly drive PIPEDA security safeguard requirements. ThreeShield maps the overlap.
Our team has directly engaged with Big-4 firms and understands accounting firm culture, client data handling requirements, and the specific social engineering threats targeting the profession. We don't apply a generic IT security framework - we apply accounting-profession-aware assessment methodology.
ThreeShield delivers accounting-firm-aware cybersecurity assessments with CISSP/CISA credentials and Big-4 engagement experience.
