01
Initial trust assessment
Snapshot of risks, technical surface, vulnerabilities and governance points to address first.
TCM steering
Maintaining mastery, beyond availability. — TCM, Trust Condition Maintenance and operations of critical systems
RUN, security, quality and compliance piloted with explicit criteria and readable governance.
Operations observation
Maintaining is no longer enough.
Silence is not a health indicator
A system with no apparent incident can hide unpatched CVEs, obsolete dependencies and invisible configuration debt.
The system holds, but you no longer really know why
Incidents are rare, yet debt, patches, changes and recovery points are no longer steered calmly.
Compliance moves faster than the reviews
AI Act, GDPR, NIS2 evolve continuously. Without active review or a designated owner, a compliance snapshot ages in a few months.
Your teams absorb shocks instead of moving forward
RUN eats build capacity, security topics stay queued, prioritisation happens under pressure.
Operations discipline
Availability
Continuous supervision, incident handling, documented escalation. SLAs defined and measured. Impact drives priority, not ticket number.
Security
Ongoing watch, CVE management, progressive hardening. Each fix documented, verified and capitalised.
Compliance
AI Act, GDPR, NIS2 continuously, not as an annual snapshot. Dedicated lead, traceability by default, audit-ready at any moment.
Technical debt
Backlog prioritised by real impact, regular reviews, action plans tracked. The system improves instead of stagnating.
AVANT Situation fréquente
- Maintenance réactive On répare quand ça casse, sans visibilité ni anticipation.
- SLA flous Pas d'objectif mesuré, ni partagé avec le client.
- Incidents non tracés Pas de post-mortem, les mêmes problèmes reviennent.
- Sécurité au rattrapage CVE patchés des semaines, parfois des mois, après publication.
APRÈS Avec REELIANT
- Supervision 24/7 Alertes en temps réel, dashboards partagés, incidents anticipés.
- SLA mesurés & partagés Objectifs co-définis, reporting mensuel transparent.
- Détection proactive Incidents identifiés et résolus avant l'impact utilisateur.
- CVE patchés sous 72h Veille permanente, correctifs testés et déployés rapidement.
What we deliver
The steering tools often missing from RUN.
02
Shared indicators and governance
SLAs, security, compliance, backlog, incidents and arbitrations tracked at a clear cadence, readable by business and IT teams.
03
Prioritised remediation backlog
Fixes, hardening, technical debt and evolvability topics ordered by real impact, not by background noise.
04
Runbook and operating procedures
Escalation, recovery, updates, supervision and decisions traced. The system becomes more operable, not just more monitored.
Operations
The RUN of AI systems.
Performance degradations are detected before they impact users. This is the minimum operating condition for AI in production.
Drift monitoring
Monitoring of models over time. Quality indicators measured continuously, alerts before business impact.
Update management
Impact control during model evolutions. No silent regression after an update.
Guardrails in production
Behaviour filter and anomaly tracking. Guardrails stay effective over time.
Continuous compliance
AI Act, GDPR, NIS2 continuously, not as annual snapshot. Audit-ready at any moment.
Proof in production
Systems taken over and sustained over time.
The value of TCM is measured in continuity, readability and the ability to absorb change without crisis.

Frequently asked questions.
What is TCM (Trust Condition Maintenance)?
An operations contract structured around 4 axes : availability (measured SLAs), security (patches, CVE), compliance (GDPR, AI Act, NIS2 continuously) and evolvability. Unlike classic managed services, TCM includes ongoing compliance responsibility.
How do you monitor AI model drift in production?
Through an LLMOps framework that continuously measures response quality indicators, detects regressions after each model update and triggers alerts before drift impacts users.
How do you stay GDPR, NIS2 and AI Act compliant over time?
Compliance is not a state but a process : regular reviews, decision traceability, up-to-date processing register, scheduled internal audits. We designate a dedicated compliance lead, always ready for an audit.
Is a system with no apparent incidents necessarily healthy?
No. Unpatched CVEs, obsolete dependencies or invisible configuration debt can coexist with a complete absence of incidents — until they don't. TCM supervision detects these silent drifts.
What do you deliver when taking over an operations scope?
A TCM takeover must make the system readable. We deliver a risk inventory, governance indicators, a prioritised remediation backlog, operational procedures and a shared governance framework with your teams.
Need to regain control over your RUN?.
