Securing the Future of Bioenergy: California Bioenergy’s Cyber Defense Transformation with ColorTokens

California Bioenergy (CalBio), a leader in renewable energy since 2006, specializes in converting methane emissions from dairy farms into renewable electricity and vehicle fuel. With over 85 operational sites across California, CalBio plays a pivotal role in the state's methane reduction initiatives. As the company expanded, ensuring business continuity and robust cybersecurity became paramount, especially to comply with industry regulations like IEC 62443 and to protect their Operational Technology (OT) environments from evolving cyber threats

Results

• Elevated Cybersecurity Score from 2.2 to 4.3
  Demonstrated a significant improvement in breach readiness. reduced the risk of lateral threat movement within its IT and OT networks.
• 100% Visibility Across IT & OT Networks
  CalBio now has a unified security architecture, allowing real-time monitoring of operational sites and critical assets.
• Increased Plant Uptime to a Consistent 100%
  Increased plant uptime from 30–60% to a consistent 100%, thanks to upgraded network infrastructure.
• Compliance with IEC 62443 Standards
  ColorTokens’ security framework helped CalBio achieve and exceed industry compliance, strengthening regulatory adherence.
• Zero Operational Downtime from Cybersecurity Measures
  Unlike traditional network security solutions that require downtime for implementation, ColorTokens’ microsegmentation was deployed without disrupting ongoing operations.
• Scalability for Rapid Business Expansion
  ColorTokens’ solution enables CalBio to securely scale its infrastructure as new operational sites are added across California.
• Real-Time Threat Monitoring & Response
  With Xassure’s 24/7 threat detection and monitoring, CalBio gains continuous visibility into security events, proactively mitigating cybersecurity risks.

Challenges

• Lack of Visibility Across IT & OT: Without a unified security architecture, monitoring and controlling access to OT networks was difficult.
• High Cybersecurity Risks: Legacy network configurations lacked segmentation and proactive monitoring, exposing OT systems to potential cyber threats.
• Regulatory and Compliance Needs: Ensuring compliance with IEC 62443 and maintaining restricted data flow policies were critical to meet industry standards.
• Operational Downtime Risks: Connectivity issues and security gaps in radio frequency networks impacted real-time data availability and business continuity.

The ColorTokens Solution

To address these challenges, CalBio partnered with ColorTokens to implement a Zero Trust-based Microsegmentation strategy, enhancing security without disrupting operations. The approach included:

• Comprehensive Security Assessment: Conducting a thorough IT/OT security evaluation to identify key risks and develop a future-state security roadmap.
• Deployment of Xshield & Xassure: Implementing the Xshield Enterprise Microsegmentation Platform to isolate critical OT and IoT systems, reducing the attack surface and preventing lateral threat movement. The Xassure platform provided 24/7 real-time threat monitoring across all sites.
• Enhanced Access Controls: Utilizing ColorTokens' Gatekeeper solution to protect sensitive OT assets, such as PLCs and HMIs, from unauthorized access.
• Network Infrastructure Upgrade: Transitioning from radio frequency networks to broadband, ensuring improved uptime and data availability.

By collaborating with ColorTokens, CalBio has fortified its cybersecurity framework, ensuring sustainable and secure operations in the renewable energy sector. Ready to Secure Your OT Infrastructure?
