Nexusguard

Company History & Founding

Nexusguard was founded in 2008 by Ryan Chin in San Francisco, California, and later moved its headquarters to Singapore. The company was built specifically to address the growing DDoS threat landscape, with a focus on the unique needs of communications service providers (CSPs). Over the years, it has grown into a trusted partner for over 100 CSPs, protecting more than 50,000 autonomous system numbers (ASNs) worldwide.

Business Model

Nexusguard operates on a managed services model, generating revenue through subscription-based DDoS protection services. A key differentiator is its DDoS-Protection-as-a-Service (DPaaS) program, which allows CSPs to white-label and resell Nexusguard’s security under their own brand, creating new recurring revenue streams. The company also offers training through its Cybersecurity Academy and threat intelligence feeds.

Core Technology & Infrastructure

The proprietary Bastions platform uses a multi-layer mitigation engine combining behavioral analysis, signature-based detection, and machine learning to identify and filter malicious traffic with minimal false positives. Nexusguard’s global network of over 50 scrubbing centers is strategically located to absorb attacks close to the source, reducing latency and preserving bandwidth for legitimate traffic.

Key Products & Services

Nexusguard’s product suite includes the Managed DDoS Mitigation Platform (core cloud-based service with 24/7 SOC support), InfraProtect (Layer 3/4 network-layer protection for CSP infrastructure), Origin Protection (shields origin servers from direct-to-IP attacks), DNS Protection (high-availability DNS scrubbing), Web Application Firewall (Layer 7 security blocking OWASP Top-10 threats), Threat Intelligence (real-time feeds and historical analysis), and Cybersecurity Academy (training and certification programs).

Market Position & Competitors

Nexusguard is purpose-built for CSP environments (5G, IoT, mobile core), positioning it against larger general-purpose vendors like Cloudflare and Akamai, though its brand presence in the enterprise segment is more limited. It has been listed as a Representative Vendor in Gartner’s Market Guide for DDoS Mitigation Services (2020) and continues to be cited for its CSP-focused approach.

Notable Partnerships & Clients

Client base includes tier-2 and tier-3 operators in Asia and emerging markets, as well as multinational ISPs. In March 2026, Nexusguard partnered with Indonesia’s Linknet Enterprise to deliver DDoS protection across Indonesia. The company also maintains active participation in industry events such as PTC’26 and ITW 2026.

Strengths & Considerations

Strengths include deep vertical expertise in CSP environments, scalable carrier-grade architecture with 50+ scrubbing centers, fully managed service reducing operational burden, and the DPaaS white-label model for incremental revenue. Considerations: the platform is geared toward larger-scale service providers rather than small enterprises, self-service portal availability may vary by region, and brand presence is limited compared to larger competitors.
