Which capability of Zscaler protects sensitive data in images?

The capability that specifically protects sensitive data in images is Optical Character Recognition (OCR). OCR technology converts different types of documents, such as scanned paper documents, PDF files, or images captured by a digital camera, into editable and searchable data. In the context of data protection, OCR plays a crucial role by identifying and extracting sensitive textual information from images.

When organizations need to ensure they are not inadvertently leaking sensitive data that may be present in images, OCR enables them to analyze these visual files for any potential risks. By extracting text from images, organizations can apply data loss prevention protocols more effectively, ensuring compliance with regulations surrounding sensitive information. This capacity to recognize and act on the data contained within images is vital for comprehensive data protection strategies.

While Data Loss Prevention (DLP) is an important security measure, it usually focuses more on preventing the misuse or exfiltration of sensitive data rather than directly interpreting the content of images. Encryption protocols safeguard data in transit or at rest, but they do not analyze the content of images. Firewall analysis is aimed at monitoring and controlling incoming and outgoing network traffic based on predetermined security rules and does not pertain to analyzing the content of images for sensitive data. Thus, OCR stands out as the relevant capability in this context
