Clearswift operates in the computer and network security sector, providing adaptive cyber security and data loss prevention solutions designed to shield organizations from threats and protect sensitive information. Its approach relies on a robust deep content inspection engine that analyzes information flowing across networks, removes policy-violating elements, and reassembles content for secure delivery with minimal business impact. The company serves government, defense and financial organizations worldwide, as well as customers responsible for critical infrastructure, offering protection across email, web, endpoints and cloud-based collaboration. Its offerings can be deployed as standalone solutions or integrated with existing systems on premises or within cloud platforms such as Office 365 or Gmail, and in February 2023 the company expanded OCR capabilities across its core email and web security products to improve detection of image-based threats. Based in Theale, England, Clearswift maintains a global footprint with offices in Europe, Australia, Japan and the United States to provide around-the-clock support.
