Overview
Nexusguard is primarily a DDoS mitigation specialist whose tagline is "Simplifying DDoS for Communications Service Providers." Founded in 2008 and headquartered in Hong Kong, it focuses on communications service providers (CSPs) and enterprises across Asia-Pacific. Its web application firewall is a secondary layer inside the Application Protection product, covering OWASP Top 10 threats, API attacks, and bots, not a standalone WAF.
The cloud service runs on a global scrubbing network, backed by proprietary intelligence on global DDoS attack patterns. Traffic is routed via DNS forwarding or reverse-proxy, supporting TCP and UDP services (HTTP, HTTPS, DNS, SIP, FTP) over IPv4 or IPv6.
Pricing is custom and enterprise-only, with no public price list and no free tier. It best fits CSPs (telcos, ISPs) plus APAC enterprises and government needing carrier-grade DDoS mitigation with WAF layered on, and is weaker for SMBs wanting self-service setup.

Frequently Asked Questions
Does Nexusguard offer a standalone WAF, or is it mainly DDoS protection?
Nexusguard is primarily a DDoS mitigation specialist; its own tagline is "Simplifying DDoS for Communications Service Providers." Web application firewall capability exists, but as a secondary layer within its Application Protection product (covering OWASP Top 10 issues such as SQL injection and XSS), not as a separate standalone WAF product.
Who is Nexusguard best suited for?
Communications service providers (telcos, ISPs), and APAC-based enterprises and government bodies that need carrier-grade DDoS mitigation, optionally with application-layer and WAF protection layered on top. It is a weaker fit for SMBs or teams wanting self-service WAF setup.
How much does Nexusguard cost?
Pricing is custom and enterprise-only; there is no public price list and no free tier. You engage their sales team for a quote, and listings (including AWS Marketplace) route to contact-sales rather than published rates.
Which regions does Nexusguard focus on?
It has particularly strong infrastructure, presence, and support across the Asia-Pacific region, with a global scrubbing network. The company was founded in 2008 and operates from Hong Kong (with additional offices including San Francisco).
How is Nexusguard deployed?
It is a cloud-based service. Web and application traffic is routed through Nexusguard via DNS forwarding or reverse-proxy setup, supporting TCP and UDP services (HTTP, HTTPS, DNS, SIP, FTP) over IPv4 or IPv6, with no on-premise appliance required.
