The Ontario Cybersecurity Framework defines cybersecurity expectations for Ontario government entities, agencies, and designated critical infrastructure. ThreeShield delivers assessments and Lavawall® monitoring aligned to the Ontario CSF requirements.
The Ontario CSF is structured around the NIST CSF functions and includes specific requirements for Ontario public-sector entities. Provincial ministries, agencies, boards, and commissions (ABCs) are expected to achieve defined maturity levels.
Complete and current inventory of IT assets, data assets, and third-party systems. Classification of information assets by sensitivity.
MFA for privileged and remote access, least-privilege enforcement, and regular access reviews. Alignment with Ontario Government identity standards.
Regular vulnerability scanning, timely patching of critical systems, and risk-based prioritization. Lavawall® provides continuous patch compliance monitoring.
Documented incident response plan with defined escalation to the Ontario government CSOC (Cyber Security Operations Centre) for significant incidents.
Security requirements in vendor contracts, cloud service provider assessments, and supply chain risk management aligned to Ontario's Cloud First and data residency policies.
Annual security awareness training for all staff. Role-specific training for IT and privileged users. Alignment with Ontario Public Service standards.
Ontario municipalities face cybersecurity obligations through the Ontario CSF and through their designation as critical infrastructure in some cases. Municipal councils are increasingly directing IT departments to achieve defined CSF maturity levels. ThreeShield has delivered assessments for public-sector clients and understands the unique constraints of municipal IT environments.
Ontario CSF aligns closely with NIST CSF and with the Canadian Centre for Cyber Security's baseline controls. Bill C-8 (CCSPA) may also impose obligations on Ontario entities operating in federally regulated critical infrastructure sectors. ThreeShield maps all applicable frameworks simultaneously.
ThreeShield's CISSP/CISA team delivers Ontario CSF maturity assessments with clear, prioritized remediation roadmaps.
