Private Health Group — HDS Architecture & Critical High Availability

The Context

Network of clinics and medical imaging centers managing electronic patient records (EPR) and real-time telemedicine flows.

Problem: Aging infrastructure unable to support the load increase of diagnostic AI. The group was targeted by data exfiltration attempts and suffered from network micro-outages impacting operating rooms and emergency services. Imperative need to comply with health certifications (HDS / HIPAA) while maintaining Cloud agility.

Our Intervention

  • Data Sanctuarization: Deployment of a Hybrid Sovereign Cloud with physical isolation of patient databases.
  • Medical Edge Computing: Installation of local on-site nodes (Edge) to guarantee critical systems operation even in case of total Internet outage.
  • Cyber Survival Audit: Ransomware attack simulation and implementation of an immutable backup system (Air-gapped) for recovery in less than 15 minutes.
  • DevOps Standardization: Automation of business application deployment to reduce human errors during updates.
  • Predictive Monitoring: 24/7 supervision of weak signals to anticipate hardware failures before they affect care.
Secure Health Infrastructure

Results

  • Zero Downtime: Maintenance of 24/7 operational continuity, including during heavy migrations.
  • Total Compliance: Unreserved validation of certification audits for health data hosting.
  • Reinforced Security: Blocking of 100% of intrusion attempts thanks to a Zero-Trust architecture.
  • AI Scalability: Capacity to integrate early detection algorithms (AI) without network slowdown.
  • Medical Staff Serenity: An IT tool that fades into the background to leave room for care.

Accounting Firm — Digital Sovereignty & NIS2 Resilience

The Context

Leading multi-site firm (150+ employees) managing ultra-sensitive fiscal, social, and banking data flows for SMEs and ETIs.

Problem: Fragmented hybrid infrastructure between aging on-premise servers and poorly orchestrated SaaS solutions. The firm faced increasing regulatory pressure (NIS2 Directive, DORA) and a persistent threat of rebound ransomware, jeopardizing the continuity of fiscal closings. Major technical debt on the client exchange portal prevented any secure automation.

Our Intervention

  • Offensive Security Audit: Complete pentest and network micro-segmentation to isolate sensitive data from the office network.
  • Sovereign Cloud Architecture: Migration to a hybrid environment (Azure/AWS) with implementation of Bring Your Own Key (BYOK) encryption for total access control.
  • Resilience Plan (BCP/DRP): Deployment of a multi-zone infrastructure guaranteeing instant failover in case of major incident on a data center.
  • Identity Governance (IAM): Deployment of Zero-Trust and hardened multi-factor authentication (MFA) on all business tools.
  • Digital Pivot Support: Training of the internal IT team on DevOps standards to secure update pipelines.

Results

  • Guaranteed Availability: Zero service interruption recorded, even during peak activity of the fiscal period.
  • Regulatory Compliance: Infrastructure certified compliant with NIS2, DORA requirements and banking security audits.
  • Performance & Costs: 30% reduction in application latency and 25% optimization of Cloud billing (FinOps).
  • Data Sovereignty: Secure centralization eliminating data silos and risks of confidential information leaks.
  • Technical Autonomy: Skill improvement of internal teams, now capable of supervising security posture in real-time.

Insurance Broker — Rescue & CRM Modernization

The Context

Brokerage firm managing sensitive data on a custom CRM. Unstable legacy code, developed without security standards, with massive technical debt (jQuery) making any evolution perilous and slow.

Our Intervention

  • Defensive security audit and correction of critical flaws (Injections, Uploads).
  • Technical supervision (Tech Lead) of the third-party development team.
  • Progressive migration strategy from Legacy to a modern stack (React).
  • Implementation of best practices (Git flow, Code Review) to stop regression.
Secure CRM Interface

Results

  • Secure CRM compliant with data protection requirements.
  • Increased performance thanks to existing code optimization.
  • Regaining intellectual control over the project against external providers.
  • Clear technical roadmap for the next 12 months.

B2B SME — Stabilize and Secure Existing Systems

The Context

Our Intervention

  • Complete architecture and code audit.
  • Implementation of distinct environments (preprod / prod).
  • Migration to a more reliable cloud infrastructure.
  • Monitoring overlay, backups, and on-call procedures.
Secure CRM Interface

Results

  • Drastic reduction in critical incidents.
  • Clear visibility on risks and correction priorities.

The Context

Fast-growing SaaS publisher, legacy architecture, manual deployments, no robust CI/CD, security concerns.

Our Intervention

  • Architecture review and evolution recommendations.
  • Implementation of CI/CD pipelines and automated tests.
  • Strengthening security posture (access, secrets, backups).
  • Supporting teams to adopt new practices.
Secure CRM Interface

Results

  • More frequent deployments, with less stress.
  • Reduction of human errors and rollbacks.
  • Clarified architecture, ready for growth.
  • Solid foundation to introduce AI and automation.

E-commerce — Gaining Availability & Cost Visibility

The Context

Online merchant with traffic peaks, hosted on an undersized server, without a clear backup or monitoring strategy.

Our Intervention

  • Progressive migration to a scaled cloud infrastructure.
  • Real-time monitoring and alerting on key indicators.
  • Backup and disaster recovery plan.
  • Detailed cost analysis and resource optimization.
Secure CRM Interface

Results

  • Sites available during critical periods.
  • Clear vision of environment costs.
  • Ability to launch campaigns without fear of crashing.
  • Reinforced confidence between IT, management, and marketing.
