Manual spreadsheets cannot deliver the structured, FR-segmented risk assessments IEC 62443 demands. The Cognisec IEC 62443 Engine automates threat–vulnerability mapping, Security Level determination and control derivation across all 7 Foundational Requirements — for every asset and conduit in your IACS.
Most organizations implement IEC 62443 using spreadsheet-based risk registers — a fundamentally flawed approach that produces subjective, inconsistent and audit-vulnerable outputs.
Spreadsheets produce one generic risk number. IEC 62443 demands FR-specific risk per asset and conduit across all 7 Foundational Requirements. One score obscures which FR domain is at risk.
Without computational modelling, Security Level assignments are manually interpreted — introducing inconsistency, bias and audit vulnerability. SL-T must be derived, not guessed.
Excel cannot model zone-to-zone conduit interactions, trust boundary evaluations or lateral movement risk paths — leaving critical IACS attack vectors unassessed and unmitigated.
The Cognisec IEC 62443 Engine computes a separate risk index for each of the 7 Foundational Requirements — enabling granular, defensible Security Level determination.
User, device and process authentication. MFA enforcement and credential management across all IACS components.
Authorization of user and process actions. Least-privilege enforcement and role-based access to industrial systems.
Protection against unauthorized modification of hardware, software, firmware and communication. File integrity monitoring.
Protection of sensitive industrial data at rest and in transit. Encryption and data classification policies.
Network segmentation, zone isolation and conduit controls. Preventing unauthorized inter-zone communications.
Detection, response and recovery procedures. Incident handling aligned to operational technology timelines.
Denial-of-service protection, resilience engineering and continuity of industrial process operations.
Each FR produces an independent Target Security Level — from SL-1 (basic) to SL-4 (sophisticated adversary protection).
The Cognisec IEC 62443 Engine implements a computationally rigorous, standards-aligned risk governance framework — transforming subjective spreadsheet assessments into objective, repeatable and audit-ready outputs.
Many-to-many relational mapping connects threat vectors to exploitable vulnerabilities across assets and conduits. Risk materializes only when a threat can exploit a present vulnerability — eliminating false positives.
Computes risk per Foundational Requirement using Threat Impact × Vulnerability Association × Zone Criticality × Asset Exposure. Produces FR-specific risk indices, not generic scores.
Automatically derives Target Security Level (SL-T) per FR per asset. Compares SL-T against Achieved Security Level (SL-A) to generate the Security Gap Index and prescriptive control recommendations.
Automatically enumerates required SR, CR and RE controls for every identified gap. Exportable CSV audit packs for national authority inspections, third-party assessments and CISO reporting.
One platform, three dedicated panels — each role sees exactly what they need for IEC 62443 governance.
The asset owner, subsystem custodian or OT security team interface. Define the industrial topology — assets, zones, conduits — and manage compliance evidence.
Dedicated portal for component suppliers, system integrators and third-party vendors to submit security evidence, vulnerability disclosures and compliance documentation.
Independent review panel for security assessors, certification bodies and compliance auditors to review FR-based risk computations, validate controls and generate audit reports.
Adopted across critical infrastructure sectors worldwide. Required by regulators, insurers and enterprise procurement teams as proof of industrial cybersecurity governance.
