Netography

Netography is an enterprise security company headquartered in San Francisco. The firm's platform, known as the Netography Fusion network defense platform, delivers real-time visibility and control across hybrid, multi-cloud, and on-premises networks. Its core premise is a departure from the appliance-heavy security architectures that dominated the 2010s: Netography uses existing network infrastructure as the data source, building a security control plane atomized across cloud, data center, and branch-office environments. The company's deployment model specializes in network detection and response (NDR) without deploying proprietary hardware. Collaborations with infrastructure incumbents like Cisco, Arista Networks, and Juniper Networks validate a strategy that attaches to what enterprises already run. In February 2022, Netography closed a $45 million Series A led by Bessemer Venture Partners and SYN Ventures, which earmarked funding for go-to-market scaling and a partner program spanning North America and select European markets. Netography has been recognized as an industry disruptor, receiving a place on the 2022 CNBC Disruptor 50 list. CEO Martin Roesch — who founded the open-source intrusion-detection project Snort before leading the Sourcefire sale to Cisco for $2.7 billion — joined the company in August 2023 as chief executive, replacing founding CEO Barrett Lyon (per the firm's official communications, August 2023). The appointment of Roesch, a figure deeply embedded in the open-source security community, signaled an operational shift toward a product-led growth motion rooted in community trust rather than traditional enterprise sales processes. The company's structural differentiator is its atomized sensing model. Instead of deploying thousands of physical or virtual appliances, Netography takes an architecture where the network itself becomes the sensor — a positioning that stands in contrast to the sensor-heavy footprints of nearly every major incumbent in the NDR space. This removes the CapEx hurdle for full coverage and shortens deployment timelines to hours rather than months.
