Client

A mature business needed IT resilience after serious disruption.

Hako has more than 30 years of operating experience. Two ransomware attacks exposed weaknesses in network security, recovery planning, infrastructure management, and internal communication.

Challenge

The business needed protection, recovery, and control at the same time.

The network was vulnerable and unstructured, backups were not reliable, and regional warehouses had weak connectivity to the central operation.

Hako also lacked a practical internal communication system and needed device-level security strong enough to prevent repeat incidents.

Solution

A layered security and continuity model for daily operations.

  1. 01

    Network & Firewall Hardening

    Techi rebuilt the network with VLAN segmentation, MAC filtering, and firewall rules designed to reduce exposure to external threats.

  2. 02

    High Availability & Control

    High-availability clustering and a Domain Controller improved resilience while centralizing device, user, and policy management.

  3. 03

    Data Protection

    Local and cloud backups were implemented, and email moved to Google Workspace for safer and more reliable communication.

  4. 04

    Connectivity & Monitoring

    Ten warehouses were connected through VPN tunnels, internal telephony was deployed, and 24/7 monitoring kept issues visible.

Results

Hako moved from reactive recovery to controlled, monitored operations.
