Realm.Security is a Boston-based cybersecurity startup building what it calls the industry’s first AI-native Security Data Pipeline Platform (SDPP). The platform automates the collection, filtering, and normalization of security logs so security teams can reduce data noise and curb expensive SIEM ingestion fees. Early customer Vensure Employer Solutions reported trimming firewall log volume by 83 %, saving $250,000 annually, illustrating the product’s cost-saving impact. The company has raised $22 million over the last 15 months and grew headcount by 250 % during 2025, underscoring rapid operational expansion. Recent leadership hires include former Cado Security SVP Holly Cappello as CRO and ex-SecurityScorecard executive Colin Jermain as VP of Data Science, reinforcing its go-to-market and AI capabilities. With new backing from Presidio Ventures, Realm plans an aggressive Asia-Pacific rollout through Sumitomo-aligned channel partners while continuing to invest in revenue, data, and AI functions.
