Strengthening Cybersecurity In the Administrative Sector

September 2, 2025

Optimized Management

Objectives

  • Strengthen the security posture, limit the attack surface, and reduce the risks of internal compromise.

  • Comply with strict regulatory standards such as ISO 27001 and PCI-DSS.

  • Meet access control, network segmentation, and traceability requirements.

The Challenge

An organization in the administrative sector was facing growing challenges in cybersecurity and network management.

The lack of segmentation between different network zones increased the risks to the infrastructure, particularly by enabling lateral movement in the event of an attack. This setup also made daily management complex and inefficient.

The solution

Prival proposed network segmentation with VLANs to secure east-west traffic. This method effectively isolated the network segments for users, physical servers, and virtual machines (VMs).

By isolating internal traffic between these entities, the solution significantly reduces the lateral attack surface, limits the risk of propagation in case of a breach, and simplifies the application of zone-specific security policies..

Results

  • Better visibility and increased control over internal traffic.
  • A reduction in risks related to lateral movement.
  • More precise management of firewall rules and inter-VLAN access.
  • Overall improvement of network security posture.
