Global market valuation was determined by conducting revenue mapping and deployment volume analysis in operational technology environments. The methodology comprised the following:
Identification of over 40 significant cybersecurity vendors and industrial automation providers in North America, Europe, Asia-Pacific, Latin America, and the Middle East
Network security (firewalls, IDS/IPS, VPN), endpoint security (EDR, antivirus, device control), application security (white-box testing, runtime protection), and data security (encryption, DLP, backup) are the categories across which the product is mapped.
Examination of annual revenues that are specific to industrial/OT cybersecurity portfolios, excluding traditional IT security revenues, as reported and modeled
Coverage of manufacturers and pure-play OT security vendors, which collectively account for 65-70% of the global market share in 2024
Derive segment-specific valuations for both on-premises and cloud-based deployment modes by extrapolating using bottom-up (deployment volume × ASP by industry vertical, including manufacturing, energy, utilities, and transportation) and top-down (vendor revenue validation against total addressable market) approaches.
