CST VerdictShort answer
Mid-market and enterprise security teams drowning in phishing bypasses and shadow SaaS will find real value in Obsidian Security Browser Extension's AiTM detection running client-side, where most EDR misses it. The tool covers three NIST CSF 2.0 areas that matter here: identity threat detection (PR.AA), data loss prevention (PR.DS), and continuous monitoring (DE.CM), which means you're not just blocking attacks but actually seeing what users are exposing. Skip this if your workforce is mostly on unmanaged devices or you need mobile coverage; browser extension reach only goes so far. Privacy-focused teams and individuals in high-risk jurisdictions need Tor Browser to defeat network-level surveillance, not just encryption. The Tor network routes traffic through multiple relays operated by thousands of volunteers worldwide, making IP-based tracking nearly impossible even against well-resourced adversaries. Skip this if your org requires managed deployment, centralized logging, or compliance with data residency rules; Tor's decentralized design explicitly prevents the visibility traditional security teams expect.
