About

OPSWAT is a cybersecurity company focused on protecting critical infrastructure by eliminating malware and zero-day attacks. The company recognizes that every file and device poses a potential threat, and as such, it emphasizes the importance of addressing these threats at various locations, including entry, exit, and rest. OPSWAT’s products are designed for threat prevention and creating secure processes for data transfer and device access, ultimately leading to systems that operate productively while minimizing the risk of compromise. With a reputation for safeguarding U.S. nuclear power facilities — where 98% trust OPSWAT for cybersecurity and compliance — the company has made a significant impact on the cybersecurity landscape. OPSWAT upholds the philosophy of 'Trust no file. Trust no device,' ensuring that no email, file, or device can enter a critical infrastructure without being validated by their innovative MetaDefender Platform. Their solutions encompass a wide range of functionalities, including peripheral and removable media protection, email security, file security, and much more. This comprehensive approach equips organizations with the essential tools to combat the growing threats in today’s digital world.
