CSSA-CI – Certified Secure Critical Infrastructure Architect Certification Program by Tonex
CSSA-CI Certified Secure Critical Infrastructure Architect develops the skills needed to design, harden, and govern complex infrastructure spanning IT, OT, cloud, and edge environments. The program focuses on architectures for energy, transportation, telecom, water, healthcare, and other essential services where downtime and compromise are unacceptable. Participants learn how to apply security patterns, segmentation, and resilience principles from the earliest stages of design through ongoing operations. Cybersecurity plays a central role in protecting critical infrastructure against ransomware, supply chain compromise, and targeted attacks from sophisticated adversaries. The program emphasizes cybersecurity as an enabler of safety, reliability, and regulatory compliance rather than a bolt on control. By the end, participants can map threats to architecture decisions, align with key standards, and guide stakeholders in building infrastructures that can withstand disruption and rapidly recover from incidents.

Course Delivery
The course is delivered through a combination of expert led lectures interactive discussions group activities and architecture focused design exercises tailored to CSSA CI Certified Secure Critical Infrastructure Architect Certification Program. Participants work with case studies threat scenarios and architecture review activities that reflect real world infrastructure environments. They also receive structured templates and checklists to apply in their own organizations along with curated readings and reference models to reinforce concepts between sessions.
Assessment and Certification
Participants are assessed through quizzes design critiques and a capstone architecture project for a representative critical infrastructure environment. The capstone requires participants to document threats controls and resilience strategies and to justify tradeoffs to technical and business stakeholders. Upon successful completion of the program and associated assessments participants receive the CSSA CI Certified Secure Critical Infrastructure Architect Certification from Tonex.
Question Types
- Multiple Choice Questions (MCQs)
- Scenario-based Questions
