The classic trap
Article 7 reads like common sense, and that is exactly where it traps you. Luxembourg financial entities supervised by the CSSF document their ICT governance in abstract policies, without ever demonstrating that their systems are genuinely reliable, adequately sized and resilient against load peaks. During an inspection, the CSSF does not settle for a signed policy: it asks for technical proof that capacity has been tested, that saturation thresholds are known, and that resilience has been validated under stress. A payment system that fails during a volume spike, a UCITS whose valuation engine saturates at month end, and the inadequacy under Article 7 becomes obvious, with penalties that can reach 1% of average daily turnover.
What "appropriate, reliable, sufficient, resilient" means in practice
The four Article 7 criteria are not declarative: they are demonstrable. CSSF circular 20/750 (as amended by 25/881) on ICT risk management spells out the operational expectations.
- Appropriate (proportionality, Art. 4): capacity must be calibrated to real operating volume, not to a theoretical estimate frozen at go-live.
- Reliable: measured availability rate, documented MTBF and MTTR, verified redundancy, not merely asserted in a vendor SLA.
- Sufficient capacity: CPU, memory, throughput and I/O saturation thresholds must be known and continuously monitored, with demonstrated headroom for order and transaction peaks.
- Technological resilience: behaviour validated under stressed market conditions through load and failover testing, not only in nominal environments.
- Kept updated: systems must be maintained updated, implying a live inventory of versions, patches and end-of-support dates, not a frozen estate.
How Luxgap automates this risk
Our Luxgap Capacity Resilience Sentinel turns the abstract Article 7 requirement into technical evidence that is defensible before the CSSF and updated in real time. The tool connects directly to your observability stack (Azure Monitor, Microsoft Sentinel, Datadog, Prometheus, eBRC, LuxConnect) and to your CMDB to continuously measure the reliability, capacity and actual resilience headroom of every critical ICT system, without relying on a questionnaire filled in by hand by the IT team.
- Continuously scans capacity metrics (CPU, memory, throughput, I/O, latency) via Azure Monitor and Prometheus and computes remaining headroom before saturation for each critical service.
- Detects peaks in orders, messages and transactions and compares observed load against documented sizing thresholds, with instant Teams alerts whenever headroom drops below the proportionality threshold.
- Maintains a live inventory of systems, versions, patches and end-of-support dates using your CMDB and Microsoft Defender, and flags any component that is not kept updated.
- Orchestrates and records load and failover tests, and computes a technological resilience score per service, aligned with CSSF circular 20/750.
- Produces a timestamped, sealed PDF report demonstrating compliance with the four Article 7 criteria, directly usable during a CSSF inspection.
