Tahsinتحصين
Every ICS and SCADA asset assessed against NCA OTCC and IEC 62443 — before an adversary finds the gap first.
A structured OT/ICS security assessment platform for Saudi critical infrastructure operators — mapping every industrial asset, scoring exposure against NCA OTCC and IEC 62443 controls, and turning findings into a tracked remediation plan.
الحصن يُبنى قبل أن يُطرق الباب
“The fortress is built before the door is tested.”
What Tahsin does
Full ICS/SCADA asset mapping
Every PLC, RTU, HMI, and historian across every site is discovered and catalogued — no asset assessed from memory or an outdated spreadsheet.
IEC 62443 compliance scoring
Each asset and zone is scored against IEC 62443 zone-and-conduit requirements, with a single rolled-up compliance score per site.
NCA OTCC-aligned methodology
Assessment scope, evidence collection, and reporting follow the NCA Operational Technology Cybersecurity Controls, ready for regulator review.
OT/IT segmentation analysis
Network boundaries between operational and enterprise IT are tested explicitly — the most common root cause of OT breaches.
Prioritized remediation plans
Findings convert directly into a tracked remediation plan, ranked by exploitability and operational impact, not just by CVSS score.
Sovereign, audit-ready reporting
Every assessment report is versioned, signed off, and stored in-Kingdom — ready to hand to auditors or the board on request.

Every ICS/SCADA asset across every connected site is inventoried automatically, without disrupting live operations.
Assess
Assets are scored against IEC 62443 and NCA OTCC controls, surfacing critical and high findings first.
Remediate
Findings become a prioritized, assigned remediation plan with clear ownership and deadlines.
Report
A consolidated, sign-off-ready assessment report is generated for compliance and executive review.
