Network Modernization for Life Sciences: Improving Security, Segmentation, and Reliability
In this life sciences network modernization project, PTP transformed a legacy environment into a secure, segmented, and fault-tolerant architecture built for reliability, scalability, and audit readiness. By upgrading aging infrastructure, introducing high availability, and separating corporate and lab systems, the organization reduced outage risk, improved security posture, and created a stronger foundation for ongoing growth.

Better security, stronger uptime, and reduced enterprise risk
1. Executive Summary
The objective of this project was to modernize a legacy network that had evolved organically over time into a more secure, resilient, and manageable architecture. The final design introduced clear segmentation between business-critical environments, added infrastructure redundancy, and eliminated major single points of failure. As a result, the organization improved operational reliability, strengthened its security posture, and better aligned the network with audit and compliance expectations.
2. Problem Statement
The client’s original network infrastructure had outgrown its initial design, creating several operational and security risks that could affect both day-to-day productivity and long-term business continuity.
- Lack of segregation: Corporate devices, manufacturing systems, and lab machines were operating on shared subnets and VLANs, increasing security exposure and making the environment harder to manage.
- No redundancy: The network depended on a single firewall and a single internet service provider, which meant a hardware failure or provider outage could result in a complete office and lab outage.
- Legacy hardware: Aging firewalls were unstable, prone to unexpected reboots, and unable to support modern bandwidth requirements, next-generation filtering, or the growing number of connected devices.
3. Proposed Solution & Design
To address these risks, PTP designed a fully isolated, two-tier network architecture focused on security, high availability, and operational continuity. The new design reduced attack surface, improved fault tolerance, and created a cleaner separation between corporate and lab environments.
- High availability gateway firewalls: A dual-firewall and dual-ISP architecture was implemented for both the corporate and manufacturing environments to support resilient internet connectivity and reduce dependence on any single point of failure.
- Redundant switching: A stacked switching design using Switch 1 and Switch 2 was deployed to provide physical link redundancy and improve availability across the environment.
- VLAN segregation: Each device class was assigned to its own VLAN so end users, servers, manufacturing systems, and lab devices could be logically separated and managed more effectively.
- Logical isolation: The network was divided into two distinct sections: a Corporate Network for employee endpoints, servers, and supporting systems, and a Lab Network for specialized manufacturing devices and associated infrastructure.
- Access control: Dedicated wired and wireless access was provided for both segments to help maintain strict isolation and reduce unnecessary exposure between environments.
4. Execution & Methodology
The project was completed in carefully planned phases to minimize disruption and support a smooth transition from the legacy environment to the new architecture.
Phase 1: Discovery & Planning
PTP completed a detailed audit of connected devices, DHCP scopes, and wireless configurations to map dependencies and reduce migration risk.
Phase 2: Corporate Migration
The corporate network was migrated first during a single weekend maintenance window, helping the organization avoid disruption during normal business hours.
Phase 3: Lab Redeployment
One month after the corporate migration, the lab network was fully redeployed on upgraded hardware to complete the modernization and extend the new architecture across the environment.
5. Challenges Overcome
- Stakeholder coordination: The project required careful communication to secure maintenance-window approvals and coordinate the re-IPing of critical infrastructure.
- Technical integration: PTP successfully managed the simultaneous cutover of firewalls, switches, and ISP circuits while maintaining service continuity throughout the migration.
6. Results & Conclusion
The project was delivered successfully within two months of equipment arrival. The organization now operates on a resilient network backbone where the failure of a single component no longer results in a full outage. By isolating corporate, manufacturing, and lab environments, the new design significantly reduced the enterprise attack surface, improved operational stability, and supported audit requirements with a stronger and more modern foundation.
