1. Client Overview

The client is a global leader in high-precision manufacturing, specializing in the R&D and mass production of precision components used across automotive electronics and consumer electronics products. With deep technical expertise and manufacturing capability, the client plays a critical role in the global supply chain, serving multiple internationally recognized brands and operating manufacturing sites and branch offices worldwide, including in China.

2. Background & Needs: Legacy Architecture Hits a Wall

As the business expanded, the client established multiple subsidiaries and overseas production sites. Headquarters staff traveling to overseas facilities previously relied on traditional VPN connections to reach headquarters, but frequently ran into unstable connection performance — particularly when connecting to and from China. Combined with the rising frequency of cyberattacks in recent years, the client grew increasingly concerned about the security risks inherent in traditional VPN access.

On the headquarters side, the original security defense relied on on-premises firewall appliances. As the number of subsidiaries grew, so did the procurement and management costs of the hardware required to keep pace.

3. The Solution: Deploying Cloudflare for Stable, Layered Cross-Border Security

With planning support from Twister5’s professional team and a specialized systems integrator, the client adopted Cloudflare’s ZTNA and SASE solutions. Leveraging Cloudflare’s global network of 330+ Anycast nodes and over 280 Tbps of network capacity, employees traveling globally or to China now enjoy stable, high-performance connections without sacrificing security. Identity verification and least-privilege access control enable effective, tiered permission management, reducing the risk of data leakage.

Having experienced Cloudflare’s comprehensive protection through the SASE deployment, the client recognized the strength and ease of implementation of Cloudflare’s broader security capabilities and moved into a second phase: extending Cloudflare’s core website defense services. This included bringing the headquarters domain under DDoS protection and WAF coverage, then extending the same protection to subsidiary websites simply by adding their domains — significantly improving both management efficiency and defense coverage through a multi-layered protection model.

4. From Zero Trust to Spectrum: Building Comprehensive Security Resilience

Over years of ongoing service, Twister5 has helped the client withstand several waves of large-scale attacks. Beyond the solutions above, the client added Cloudflare Spectrum in the latest phase of the engagement. Cloudflare Spectrum protects non-HTTP internal applications, strengthening the security of core systems such as ERP and communication platforms — further reinforcing the client’s existing security architecture.

What began as protection for a single use case — the corporate website — has expanded into a comprehensive security deployment covering the client’s entire network environment. The client has highly praised Cloudflare’s performance in Zero Trust SASE architecture design, global performance optimization, and cloud flexibility, and has likewise commended Twister5’s team for years of consistent implementation guidance, technical support, and timely product updates.

5. Why the Client Chose to Stay: A Long-Term Partnership

Cloudflare’s continued investment in AI-driven security innovation, evolving AI products, and global data center expansion has been a key factor in the client’s decision to maintain this as a long-term partnership. The client also regards Twister5 as a core strategic partner in its cybersecurity journey. As a leading managed security provider, Twister5 will continue expanding AI-powered automated alerting and defense capabilities, moving toward a diversified, one-stop managed security platform — using AI to defend against AI-driven attacks — as both parties continue optimizing the client’s security posture to meet future digital challenges.
