What NANO MEDIA Inc does
SentryMark (NANO MEDIA Inc) is a privately held cybersecurity services provider founded in 2021 by CEO Albert Vasquez, headquartered in San Jose, California. The company delivers managed cybersecurity services — vulnerability assessment, advanced monitoring, incident response, and browser security — to mid-sized and large enterprises across banking, healthcare, government, system integrator, and service provider sectors, with a stated focus on North American and Asian markets. Its operational footprint comprises a regional office in Tokyo and four Security Operations Centers located in Florida, North Carolina, Malaysia, and the Philippines.
The company's core technology stack combines a tech-agnostic integration layer with AI-powered threat detection, automated alert aggregation, and asset prioritization. The flagship product, ConcealBrowse, is a browser security extension powered by the ConcealSherpaAI engine, licensed through a technology partnership with Conceal, which autonomously identifies harmful webpages to block attacks exploiting weaponized links. SentryMark supplements this with proprietary dynamic breach risk scoring, continuous red-team monitoring, and a military-grade analytics platform for advanced 24/7 monitoring, claiming mean time to detection reductions from months to hours.
SentryMark's revenue model rests on subscription-based managed security services (24/7 monitoring, vulnerability assessment, incident response), recurring browser-security license fees (with a freemium tier of up to five free licenses), and professional services including digital forensics and ransomware negotiations. Go-to-market combines direct enterprise field sales in North America and Asia with a channel-driven model in Japan, leveraging distributors and resellers including NetLand, Nippon Telematique, and Hitachi Systems Engineering Services. The company is founder-owned, privately held, and has not disclosed external funding or revenue figures.
