Bucher Municipal Advances cybersecurity by Shrinking Attack Surface and Eliminating Lateral Threat Movement with Zscaler

Bucher Municipal, a prominent supplier of vehicles and equipment for cleaning and clearing operations on public and private roads, has made significant strides in enhancing its cybersecurity framework. With a global presence in 140 countries, over 180 Customer Service Centres across five continents, and a workforce of 2,500 employees, the company recognized the need for a robust security posture. Collaborating with Zscaler, Bucher Municipal has successfully implemented a Zero Trust architecture, which has proven instrumental in securing branch connectivity, minimizing the attack surface, and preventing lateral threat movement.

Transitioning to Zero Trust

The shift to a Zero Trust model has transformed Bucher Municipal’s operational efficiency. The organization has eliminated the need to route traffic back through centralized hubs, resulting in faster access for users to their internet destinations. This improvement has been one of the most notable benefits for the user base, enhancing overall productivity.

From a security standpoint, the transition has provided Bucher Municipal with enhanced visibility across its infrastructure. The company can now monitor a broader array of assets and servers, allowing for a more comprehensive understanding of its operational environment. This increased visibility is crucial for identifying potential vulnerabilities and responding to threats in real-time.

Strategic Partnership with Zscaler

The decision to partner with Zscaler was driven by both the capabilities of the platform and the collaborative relationship established between the two organizations. Bucher Municipal utilizes several Zscaler components, including Zscaler Internet Access (ZIA), Zscaler Private Access (ZPA), and Zero Trust Branch. This partnership has marked a significant departure from previous solutions, fostering a more integrated approach to cybersecurity.

The implementation of ZIA has granted Bucher Municipal granular control over user access. Instead of broadly allowing user groups to access cloud storage, the organization can now specify detailed permissions, such as whether users can download or upload data. This level of control surpasses what was previously available, thereby enhancing security protocols.

On the private access front, the integration with CrowdStrike has yielded substantial improvements. By leveraging device posture capabilities, Bucher Municipal has effectively obscured its infrastructure from potential threats. Penetration testing has demonstrated that attempts to disable CrowdStrike result in immediate loss of visibility into the environment, underscoring the effectiveness of this integration.

Future Cybersecurity Priorities

Bucher Municipal’s cybersecurity strategy is focused on several key priorities moving forward. One significant goal is upgrading traditional branch connectors to the U.S. version of Zero Trust Branch. This upgrade is expected to further enhance the security framework and streamline operations.

Additionally, the organization is committed to expanding the use of Airgap technology. Already implemented in select locations, Airgap is being rolled out to others to prevent lateral movement not only between locations but also within individual sites. This multi-layered approach adds an extra layer of protection against potential threats.

User experience monitoring is another critical area of focus. Bucher Municipal plans to broaden the deployment of Zscaler Digital Experience (ZDX) across the organization. While already utilizing the platform, the aim is to extend its reach to improve user experience and operational efficiency.

Governance Challenges in AI Integration

As the cybersecurity landscape evolves, the integration of AI agents presents both opportunities and challenges. The transition from SD-WAN to Zero Trust has been ongoing, but the rapid advancement of AI technology adds complexity to governance. Understanding how AI agents are utilized within the organization is paramount, necessitating robust controls over their access and functionalities.

Bucher Municipal acknowledges that the proliferation of AI agents will continue to increase, making secure management essential. The rapid evolution of AI capabilities, as evidenced by advancements in models like ChatGPT, highlights the need for organizations to maintain visibility and control over their AI deployments.

The principles of cybersecurity remain foundational. A clear understanding of the infrastructure is essential for implementing effective policies. Deploying ZPA has significantly aided Bucher Municipal in avoiding open access policies by ensuring a comprehensive grasp of the environment.

Redefining Security with Zero Trust

Historically, cybersecurity strategies centered around the network perimeter, focusing on firewalls and access control. However, the proliferation of endpoints and access points has rendered this approach increasingly difficult to manage. Zero Trust offers a paradigm shift by reducing the attack surface through minimized entry points into the organization’s infrastructure.

Bucher Municipal has redesigned its network architecture to separate user segments from the underlying infrastructure. While maintaining data centers and cloud environments, the overall attack surface has been significantly reduced, simplifying protection efforts.

Bucher Municipal was among the early adopters of Zero Trust, a decision driven by the desire to stay ahead of emerging threats. The organization has benefited from ongoing discussions with Zscaler about product improvements, fostering a collaborative environment that has led to enhancements in the platform.

The integration of Airgap technology has been a notable advancement, providing additional security benefits. Bucher Municipal appreciates the direction Zscaler has taken with branch connectors, and continuous improvements have optimized the solution for their specific needs.

Bucher Municipal’s proactive approach to cybersecurity, characterized by its partnership with Zscaler and the implementation of a Zero Trust framework, underscores the importance of adapting to an evolving threat landscape. The organization’s commitment to enhancing visibility, control, and user experience positions it well in the ongoing battle against cyber threats.
