Nexusguard
Sells DDoS scrubbing capacity and carrier partnerships to regional telcos in Asia-Pacific.
On the record
Checkpoint: Linknet Enterprise (Indonesia) MoU conversion to booked recurring revenue
The call
A mature regional DDoS vendor holding onto carrier relationships while headcount slips and larger scrubbing networks circle its home market.
Nexusguard runs physical centers that protect internet providers and telecom companies from DDoS attacks, which are floods of fake traffic designed to crash websites and networks. The company has real advantages: 40 to 50 data centers around the world, relationships with over 100 internet providers, and 15 years of data about how attacks work. However, bigger companies like Cloudflare and Akamai are moving into the same business and can serve the same customers much more cheaply and easily because they already have giant networks everywhere. Nexusguard's staff is not growing, it is not raising new money, and nobody knows for sure where it is really headquartered or when it was actually founded, all signs that it is stuck rather than moving forward. The one thing that could turn this around: if Nexusguard can convert its deal with Linknet Enterprise in Indonesia into actual paying customers and then sign up two or three similar major telecom deals in the next year, it would prove the company still has a real path forward.
Why
01
AI pressure: None apparent. ML based DDoS detection is now standard across the industry, so it no longer sets Nexusguard apart from rivals. Could AI do the core job? Only partly.
02
Bigger players: Cloudflare (Magic Transit) and Akamai (Prolexic). Both run scrubbing at far larger scale and could extend white label deals to the same emerging market telcos Nexusguard courts. Could a giant copy it? Yes, easily.
03
What protects it. Its 100+ direct ISP and CSP relationships plus 15+ years of regional attack telemetry that big scrubbing networks have not replicated locally.
What would change this call
Nexusguard discloses a Series X funding round within 12 months. Would show investors still see growth potential despite flat headcount.
Linknet Enterprise MoU converts to booked recurring revenue. Would confirm the regional-telco channel is still winnable, not just talk.
Headcount figure (Crustdata tracked) rises above 142 within a year. Would signal reversal of the current contraction trend.

Key numbers
- Headcount ~135, down 1.5% year over year
- Growth Score 38 out of 100
- 100+ direct ISP/CSP partners claimed
Named risks
- Hyperscaler capacity gap versus Cloudflare and Akamai erodes core scrubbing differentiation.
- No confirmed external funding disclosed, raising questions about capital runway against better-funded rivals.
- Core AI/ML detection ('Smart Mode') has become industry table-stakes, reducing product differentiation.
- Unresolved corporate identity across sources on HQ location and founding year signals possible undisclosed restructuring.
- Flat-to-declining employee headcount trend per workforce trackers through mid-2026 signals stagnation, not growth.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Cloudflare | losing to | 500 Tbps capacity (Apr 2026) vs Nexusguard's vendor-claimed 3+ Tbps |
| Cloudflare | losing to | 300+ city POPs, 12,000 networks (Jul 2026) vs Nexusguard's 40-50 scrubbing centers |
| Akamai (Prolexic) | losing to | Publicly traded, vertically integrated CDN giant with no structural block from entering Nexusguard's regional-telco channel |
| NETSCOUT (Arbor) | contesting | Arbor TMS added equivalent AI/ML detection functionality in February 2025 |
Questions people ask
- Is Nexusguard profitable?
- No audited financials are public. Nexusguard is privately held with no confirmed funding round disclosed in press as of 2026-07. Aggregator revenue estimates exist but are unconfirmed, so profitability cannot be verified from public sources.
- Could AI replace Nexusguard?
- Nexusguard's core ML detection, 'Smart Mode,' is now industry table stakes; NETSCOUT added equivalent AI/ML to Arbor TMS in February 2025. Its remaining edge is physical: 40-50+ scrubbing centers and 100+ ISP partnerships that pure AI software cannot replicate quickly.
- Who is Nexusguard's biggest competitor?
- Cloudflare and Akamai are the dominant threats. Cloudflare reported 500 Tbps of network capacity (April 2026) versus Nexusguard's vendor-claimed 3+ Tbps, and operates 300+ city POPs versus Nexusguard's 40-50 scrubbing centers, per Cloudflare's own July 2026 blog post.
- Who owns Nexusguard?
- Nexusguard is privately held with no confirmed parent company, acquisition, or funding round found in press as of 2026-07-25. Its CEO is named as Andy Ng in 2026 press releases, though earlier profiles listed a different CEO, suggesting a leadership change over time.
- What is Nexusguard's headquarters and founding year?
- This is genuinely unresolved: the company's own 2026 press releases say founded 2008 and headquartered in Singapore, while other trackers cite 2012 and Hong Kong (Tsuen Wan) or San Francisco, with no authoritative resolution found as of 2026-07-25.
- Did Nexusguard land any major new deals recently?
- Yes, Nexusguard signed a memorandum of understanding with Linknet Enterprise in Indonesia on 2026-03-18 to combine Linknet's 100 Gbps capacity with Nexusguard's 3+ Tbps scrubbing infrastructure, per a joint PR Newswire release.
