Network design has always played a critical role in ensuring seamless operations in Biotech.  However, data security and reliable communication are often at odds with each other. Sites, which include laboratories, research facilities, and manufacturing plants, demand specialized network infrastructures to support their research, maintain sensitive data, and a myriad of sophisticated manufacturing equipment.  This blog explores the key considerations in designing networks for biotech sites, focusing on the balance between secure networking and isolated designs to achieve optimal reliability.

The Unique Needs of Biotech Sites

Biotech sites are unique environments where cutting-edge research and development activities may occur in conjunction with GxP manufacturing.  These sites generate and handle vast amounts of sensitive data, from genomic sequences to proprietary drug formulations for later use down the pipeline. Network infrastructure must support high-performance computing, secure data storage, and reliable communication between various departments and external partners.

Key requirements for biotech network design include:

  1. Reliability and Uptime: Network downtime can halt critical research and production processes.
  2. High Data Throughput: Biotech applications often involve large datasets that require high-speed data transfer.
  3. Data Security: Protecting intellectual property and sensitive patient data is paramount.
  4. Compliance: Adherence to regulatory standards such as 21CFR Part 11, HIPAA, and GDPR is mandatory.

Secure Networking vs. Isolated Design

When designing networks for biotech sites, two primary considerations are isolation and secure networking design.  Each approach has its advantages and trade-offs, and an optimal solution often involves a combination of both depending on the data sharing requirements.

The Isolated Design

An isolated design involves physically or logically separating different parts of the network to enhance reliability and security. This can be achieved through:

  1. Air-Gapped Networks: Completely isolating critical systems from external networks.
  2. Virtual LANs (VLANs): Creating separate virtual networks within the same physical infrastructure, but requires the entire network to be qualified.
  3. Dedicated Networks: Using separate network hardware for different functions, such as separating research networks from administrative networks, ensuring that the qualified network is never impacted by enterprise changes.


  • Enhanced Security: Isolation reduces the risk of cross-contamination between different network segments.
  • Improved Reliability: Issues in one part of the network do not affect other parts, ensuring continuous operation.
  • Simplified Compliance: Isolated networks can be easier to audit and comply with regulatory standards.


  • Higher Costs: Maintaining separate networks can be expensive in terms of hardware and management.
  • Limited Flexibility: Isolated networks can be less flexible and harder to integrate with other systems.
  • Data Sharing is cumbersome: Admittedly, data can be shared through external drives or paper copies, but as soon as you rely on external devices, you have opened the door to potential security vulnerabilities.  External drives can be lost or stolen, physical copies can be mishandled, misplaced.  There is also the risk of external drives being infected with malware, which can compromise the entire network when plugged into secure systems.  Furthermore, the manual transfer of data is time-consuming and prone to human error, which can result in delays and inaccuracies that impede research progress and productivity. 

Secure Networking

Secure networking focuses on layering and protecting data communications from unauthorized access, ensuring confidentiality, integrity, and data availability. Key components of secure networking include:

  1. Layered Levels of Segmentation: Establishing layers per PERA (Purdue Enterprise Reference Architecture) ensures that similar tasks or functions are within similar layers and can be isolated if need be without impacting operations if threats arise.  Essentially dividing the network into smaller segments contains potential breaches and limits lateral movement of attackers.
  2. Firewalls and Intrusion Detection Systems (IDS): Provide a first line of defense against external threats.
  3. Encryption: Encrypting data in transit and at rest to protect sensitive information.
  4. Access Controls and Role Based Authentication: Implementing strict access controls to ensure that only authorized personnel can access certain parts of the network or systems.


  • Data Protection: High level of security for sensitive and proprietary information.
  • Compliance: Easier to meet regulatory requirements for data protection.
  • Scalability: Secure networking model can be scaled with the growth of the biotech site without creating additional isolated networks.


  • Complexity: Implementing and managing secure networks can be complex and resource-intensive as each change or addition requires strict documentation practices, pre-evaluation, and change control.
  • Performance Overheads: Security measures such as encryption can introduce latency and affect network performance on specific network layers.

Balancing Security and Isolation for Optimal Reliability

To achieve the optimal balance between secure networking and isolated design, biotech sites should consider the following strategies:

  1. Hybrid Approach: Implement a hybrid design that combines secure networking principles with isolated segments as necessary, and add additional firewalls between layers.  For example, using VLANs to segment the network layers, employing robust security measures north and south within each segment and isolating all east/west traffic.
  2. Redundancy and Failover: Ensure that all systems have redundant paths and failover mechanisms to maintain reliability in case of network issues or hardware failures.
  3. Add Inline Security and Visibility: Inline security taps provide real-time monitoring and deep packet inspection, facilitating advanced threat detection and prevention in compliance with regulatory standards.  The comprehensive traffic analysis enforces security policies, and should be integrated with existing security tools for unified management. This results in improved network reliability and performance, essential for protecting sensitive biotech data and ensuring uninterrupted operations.
  4. Regular Audits and Monitoring: Conduct regular security audits and continuous network monitoring to identify and address vulnerabilities promptly.
  5. Training and Awareness: Train staff on security best practices and the importance of maintaining network integrity.
  6. Collaboration with IT and Security Experts: Work closely with IT and cybersecurity experts to design and implement a network that meets the unique needs of the biotech environment.
