DefensX is a cybersecurity company that develops a Zero Trust Secure Web Browser extension and related endpoint protection solutions. The company's core product is a cloud-native browser-based security platform designed to protect end-user devices from web-borne threats without requiring on-premises hardware appliances. The platform is delivered as a software subscription and can be provisioned at the endpoint level, with users able to install it independently. Key capabilities include Zero Trust Web Protection, Zero Trust Credentials, Zero Trust File Protection, Remote Browser Isolation (RBI), and DNS++ filtering. These features work together to isolate web and browser activity, prevent phishing, block malicious file downloads, and protect credentials from being harvested. DefensX targets organizations across multiple verticals including financial services, healthcare, government, education, media and entertainment, and energy, with a focus on securing remote and mobile workforces. The solution is positioned as an alternative to traditional appliance-based Secure Web Gateway (SWG) products, emphasizing lower cost and ease of deployment. The company operates on a cloud-first architecture and distributes its product through channel partners and distribution networks across multiple global regions, including MENA. DefensX is headquartered with ties to Turkey and has received investment from the METU Technopark Venture Capital Investment Fund (Invest101), a fund associated with the Türkiye Development Fund.
