Migrating a critical firewall to a high-availability FortiGate cluster

The challenge

All company traffic relied on a single virtualised firewall that handled both perimeter security and routing between internal networks. Ageing and without redundancy, it was a single point of failure for critical services. The migration had to happen without disrupting operations.

What we did

  • Full audit of the existing configuration and a migration plan approved by the client
  • Both firewalls running side by side during the transition, with rollback at every step
  • Rules, objects and network services reproduced exactly so nothing breaks
  • Gradual cut-over, network by network, with traffic spread across two Internet links (SD-WAN)
  • Automated testing: every rule replayed and validated one by one on the new firewall

The result

Migration completed with no service interruption, 100% rule compliance validated, and a modern, redundant security platform. A recommendations report was delivered for the next hardening steps.

Completed project Enterprise

Replacing an end-of-life firewall cluster in a single day

The challenge

The existing firewall cluster was reaching vendor end of life, with security updates no longer guaranteed. It had to be replaced without changing the network architecture or disrupting users, VPN included.

What we did

  • Complete new configuration prepared ahead of the intervention
  • Port-for-port replacement with a pair of next-generation FortiGates
  • High availability with dual synchronisation links and session pickup
  • Networks, rules, DHCP, VPN and address translation migrated exactly as before

The result

Completed in one day, failover tested under real conditions in under 2 seconds with no noticeable interruption. Acceptance report signed without reservation.

Private datacenter modernisation: a high-availability virtualisation cluster

The challenge

The company’s servers ran on ageing infrastructure with no tolerance for hardware failure. Network performance was also degraded, with no identified cause.

What we did

  • Design of a multi-node Proxmox cluster with Ceph distributed storage
  • Planned migration of all virtual machines, with no data loss
  • In-depth network diagnosis: bottleneck identified and fixed
  • Formal acceptance testing, followed by a maintenance contract

The result

A redundant infrastructure able to survive a server failure, network losses fully eliminated and long-term operations secured.

Next-generation firewall and dual Internet access with no downtime

The challenge

A basic router handled connectivity: no advanced filtering, two Internet links that did not work together and no standard remote access for administration.

What we did

  • Router replaced by a FortiGate with advanced protection (IPS, web filtering, antivirus)
  • Addressing plan reproduced exactly: nothing to reconfigure on devices
  • SD-WAN across both links: load balancing and automatic failover
  • Secure VPN for administrators, admin interface closed to the Internet

The result

If one link fails, traffic switches over automatically within seconds. A protected network, both links in use and secure remote administration.

What we did

  • FortiGate firewall with IPS, web filtering, antivirus and application control
  • Two fibre links combined in SD-WAN with priority for business applications
  • User VPN for secure remote work
  • Documentation and knowledge transfer to the team

The result

A network protected against common threats, smooth business applications and secure remote work for the whole team.

Completed project Private institution

Access control: doors, locks and lift

The challenge

The institution wanted to control and log access to several sensitive areas, including the lift, with a solution that is easy to manage day to day.

What we did

  • Access survey and the right equipment chosen for each door
  • Connected locks, magnetic-lock door and lift access control
  • Installation, access-rights setup and training for administrators

The result

Controlled, traceable access managed from a single point, with no hassle for authorised users.

Unified 3CX telephony integrated with an AI voice agent

The challenge

An old open-source PBX handled both staff calls and those of an AI voice agent. The setup was complex to maintain, with no redundancy or safeguards against toll fraud.

What we did

  • Target architecture on 3CX, with native integration of the AI voice agent and CRM
  • Anti-fraud measures: firewall filtering and call limits
  • Proof of concept validated before buying licences, then a phased migration
  • Planned cut-over with rollback available

The result

Human and AI calls brought together on one modern, secure and easier-to-manage PBX, sized for high call volumes.

Completed project Group

Cloud phone system: an end to choppy calls

The challenge

The PBX was hosted far from its users: conversations suffered regular dropouts and audio loss, especially on mobile calls.

What we did

  • Voice-quality diagnosis (voice-stream analysis)
  • PBX migrated to better-connected cloud hosting with only minutes of downtime
  • Automatic monitoring with restart on failure and hardened security
  • On-site GSM gateways and mobile apps for staff

The result

Audio loss eliminated, clear calls and significantly lower hosting costs. Teams stay reachable anywhere on the company number.

Completed project Group

A secure, remotely managed mobile fleet (MDM)

The challenge

The group had to meet strict security requirements for its teams’ business smartphones: inventory, application control, updates and data protection in case of loss or theft.

What we did

  • MDM comparison, choosing the one already included in the existing security licence
  • Phones enrolled by QR code, with a step-by-step guide
  • Business apps installed and updated remotely
  • Remote lock and wipe, security policies applied automatically

The result

Computers, servers and mobiles managed from a single console, group security requirements met, with no extra software purchase.

Secure access to a biometric time-tracking system

The challenge

The time-tracking software needed remote access for HR teams, without exposing the server to the Internet or disrupting the biometric terminals already in use.

What we did

  • Encrypted Cloudflare tunnel: no port open to the Internet
  • Valid HTTPS certificate and hardened security headers
  • Automatic monitoring every 5 minutes with service restart
  • Documented operating and rollback procedure

The result

Secure access from anywhere for managers, no downtime for the terminals, and a server that is no longer exposed.

Network audit, recabling and clean-up for a healthcare facility

The challenge

Years of piecemeal additions had left chaotic cabling, network equipment sitting on the floor and no documentation. Critical services depended on this fragile, hard-to-troubleshoot installation.

What we did

  • Full audit of the existing setup and a clean-up plan
  • Category 6 cabling, locked network cabinet and cable trays
  • Separation of power and data cabling
  • Wi-Fi optimisation and network plans handed over

The result

A clean, physically secured and fully documented network, delivered in a few days of work with a closing report.

Ongoing managed IT for a multi-site group, for several years

The challenge

Round-the-clock operations, teams spread across several cities and systems critical to the group’s own customers. The group needed a partner able to handle both day-to-day support and major incidents.

What we did

  • Multi-site user support and scheduled interventions
  • Monthly activity report shared with management
  • Advanced incident diagnosis (network analysis) and preventive measures
  • Support towards ISO 27001 best practice: backup and restore testing

The result
