Key people at NexDefense, Inc..
NexDefense, Inc. has raised $2.4M in total across 1 funding round.
NexDefense, Inc. delivers specialized software providing cybersecurity for industrial control systems (ICS) within critical infrastructure. Its core product offers real-time network visibility and continuous monitoring, equipping operators with actionable intelligence to detect and mitigate malicious cyber threats. The company's technical approach focuses on maintaining the integrity of complex operational technology environments.
The company was founded in Atlanta, GA, in 2012 by Mike Sayre, Derek Harp, and Michael Assante, with early assistance from cybersecurity pioneer Tom Noonan. Their founding insight stemmed from the observed complexity and inherent lack of visibility within ICS, exposing vital systems to significant, often hidden, cyber risks. The underlying technology was initially funded and developed through a U.S. Department of Energy initiative.
NexDefense served industrial companies and operators across various critical infrastructure sectors. Its vision centered on enabling secure and reliable industrial operations by equipping users with robust cybersecurity defenses. The company aimed to provide essential knowledge and tools necessary to safeguard these vital systems against evolving cyber adversaries.

NexDefense, Inc. was a cybersecurity startup founded in 2012 in Atlanta, GA, specializing in software to protect industrial control systems (ICS), including SCADA, process, and distributed systems critical to infrastructure like energy and manufacturing.[1][2][5] The company developed the NexDefender Suite and its flagship product Sophia, an anomaly detection system originating from Idaho National Laboratory experts, enabling operators to monitor systems, detect changes, track data exfiltration, and respond to threats for reliable automation.[1][2] It served industrial operators facing cyber risks, solving visibility and integrity issues in ICS environments, raised $8.19M, employed 12 people, and reached full product readiness before its acquisition by Dragos in March 2019.[1][2]
NexDefense was co-founded in May 2012 by Derek Harp (Executive Chairman) and Mike Sayre (President & CEO).[1][5] Harp, a serial entrepreneur and former US Navy Surface Warfare Officer with expertise in security and intelligence, had prior successes including co-founding LogiKeep and inventing Intellishield (acquired by Cisco via Vigilinx).[1] Sayre brought over 30 years in tech and manufacturing, including leadership at 2Checkout.com and Pinnacle Data Systems, focusing on growth, M&A, and operations.[1] The idea stemmed from acquiring and commercializing Sophia's technology from Idaho National Laboratory to address rising cyber threats to global critical infrastructure, achieving early commercial availability and traction in the ICS security space.[1]
NexDefense rode the surging demand for ICS/OT cybersecurity amid rising nation-state threats to critical infrastructure, like those targeting energy grids and manufacturing post-Stuxnet.[1][2] Its timing aligned with industrial digitization (Industry 4.0) exposing legacy systems to modern cyberattacks, where traditional IT security fell short—market forces like regulatory pressures (e.g., NIST for critical infrastructure) and incidents amplified needs for specialized visibility tools.[2][3] By commercializing national lab tech and fueling Dragos' platform, it influenced the ecosystem, pioneering free asset tools that lowered entry barriers for OT security adoption and advanced collective resilience in advanced manufacturing and automation sectors.[2]
Post-2019 acquisition, NexDefense's tech endures within Dragos, whose ICS platform continues scaling amid escalating geopolitical cyber risks to infrastructure.[2] Expect amplification through AI-driven threat hunting and expanded OT visibility, shaped by trends like zero-trust for ICS and supply chain attacks. Its legacy elevates Dragos' influence, potentially driving ecosystem-wide standards—cementing NexDefense's role from niche innovator to foundational pillar in safeguarding civilization's backbone.[2]
