Spur Intelligence, a cybersecurity startup based in Lake Mary, Florida, has raised a $200 million funding round led by Insight Partners, the company announced Tuesday. The investment underscores the escalating arms race between enterprises and increasingly sophisticated automated traffic designed to mimic human behavior.
Founded in 2017 — five years before ChatGPT’s public launch — Spur was early to recognize a problem that has since become a defining challenge for the internet. The startup’s technology helps organizations distinguish legitimate human users from traffic generated by criminal VPNs, residential proxy networks, and anonymization infrastructure that masks malicious activity.

Bots now outnumber humans online
The funding arrives at a historic inflection point. Cloudflare reported last month that bots are now more active on the internet than humans for the first time. Cloudflare CEO Matthew Prince posted on X that the milestone arrived earlier than his own predictions. “Thought it would be end of 2027, then early 2027, but agentic traffic growing so fast that bots have now passed human traffic online for the first time in the Internet’s history,” Prince wrote, citing the company’s latest traffic report.
Insight Partners managing director Thomas Krane framed the investment as a response to a growing blind spot for organizations. “As sophisticated criminal VPNs, residential proxy networks, and anonymization infrastructure proliferate, organizations are increasingly operating with a critical blind spot: they can see the activity, but not the infrastructure behind it,” Krane said in a statement.

What the funding means for the cybersecurity market
The $200 million round positions Spur among the better-funded players in the bot-detection space, a category that includes publicly traded companies like Cloudflare and Akamai, as well as privately held startups. The investment signals that venture capital continues to flow heavily into cybersecurity infrastructure, even as broader tech funding has cooled in some segments.
For enterprises, the stakes are high. Bot-driven attacks can distort analytics, enable credential stuffing, help ad fraud, and power large-scale disinformation campaigns. Traditional detection methods that rely on simple behavioral signals have become less effective as bots adopt human-like browsing patterns and rotate through residential IP addresses.
Spur’s approach focuses on identifying the underlying infrastructure behind traffic — the servers, proxies, and networks that bots use — rather than just analyzing the behavior of individual sessions. This infrastructure-level visibility gives security teams a way to block threats that would otherwise appear legitimate.
The company has not disclosed its valuation or whether the round included secondary share sales. Spur has now raised approximately $300 million in total funding since its founding, according to data from PitchBook.
What to watch next
The bot-detection market is likely to see further consolidation as enterprises demand integrated security platforms rather than point solutions. Cloudflare’s recent traffic report suggests the problem will only intensify as AI agents — automated programs that perform tasks on behalf of users — become more widespread. Companies that can demonstrate real-time detection of advanced bot infrastructure will be well-positioned as corporate security budgets continue to grow.
