Realm.Security, the cybersecurity company developing an AI-native security data pipeline platform, has secured a $2m strategic investment to support the next stage of its global growth.
The funding was supplied by Presidio Ventures, the corporate venture arm of Sumitomo Corporation. Sumitomo, which is headquartered in Japan, operates a wide range of subsidiaries worldwide, including SCSK, a major systems integrator offering managed IT and cybersecurity services to more than 8,000 enterprise clients.
Realm.Security’s platform is designed to help security teams reduce data noise, handle spiralling storage and compute requirements, and better understand the vast volumes of information passing through modern Security Operation Centres. Its Security Data Pipeline Platform gives enterprises the tools to manage, filter and normalise security data at scale, a capability the company argues has traditionally only been accessible to the largest global organisations.
The company plans to use the investment to expand across the Asia-Pacific region in 2026, using Sumitomo’s network to establish partnerships and strengthen its leadership team. The Asia-Pacific cybersecurity market has become the third-largest globally, and Realm.Security views Japan as a strong entry point due to the high proportion of enterprises that outsource their SOC operations.
Additional updates from the company include industry recognition and significant customer milestones. The firm was recently named an “Emerging Leader” in the security data pipeline platform market by analyst house SACR, and was listed among the 50 companies shaping the local start-up ecosystem in the BostInno 2025 Fire Awards. Realm.Security also reported a notable client success with Vensure Employer Solutions, which used the platform to cut firewall log volumes by 83%, saving $250,000 per year.
Realm.Security CEO Pete Martin said, “We’re excited to bring on Presidio Ventures as a strategic investor as we meet rising global demand for our platform from security teams who are drowning in data noise and facing spiraling storage and compute costs. This investment caps an impressive first full calendar year for Realm, and we believe Sumitomo’s deep connections will help us enter the Asia-Pacific market and scale quickly in 2026. The region is now the third-largest cybersecurity market globally, and Japan is a particularly compelling entry point for our channel-led strategy, given that many enterprises there outsource their Security Operation Centers.”
The latest investment follows a $15m Series A round completed in October, led by Jump Capital with participation from Glasswing Ventures and Accomplice. The company has also grown its workforce by 250% this year and made senior appointments including Holly Cappello as chief revenue officer and Colin Jermain as vice president of data science.
