Sofia Reinholt is Senior Editor at BrowserSource, where she leads coverage of web privacy, browser fingerprinting, tracking protection, and privacy tool evaluation.
Sofia’s background is in web security and applied privacy research. She has studied browser fingerprinting techniques, third-party tracking architectures, and the privacy properties of browser features including the Privacy Sandbox proposals. Her work focuses on the gap between what privacy tools claim to protect against and what they actually defend — a distinction she considers essential to honest coverage.
Her reviews of VPNs, ad blockers, and anti-fingerprinting tools are grounded in technical testing rather than marketing comparisons. She is particularly interested in how browsers and extensions handle the tension between web functionality and user privacy, and in how ordinary users can make meaningful improvements to their privacy posture without sacrificing usability.
Sofia contributes to BrowserSource on privacy tools, browser security, tracker protection, and web fingerprinting.
