Data Security & Governance: 13 Tools compared

BigID is an enterprise data security and compliance platform that uses AI-driven classification to discover, classify, and contextualise sensitive data across cloud, SaaS, on-premises, and development environments. BigID goes beyond traditional pattern matching to identify data relationships, correlate data across sources, and provide actionable intelligence for privacy, security, and governance use cases. Its data intelligence approach helps organizations understand not just what data they have, but how it relates, who owns it, and what risk it presents.

Fendr is a browser-extension based data loss prevention and AI governance product that monitors and controls what employees paste or upload into ChatGPT, Copilot, Claude, Gemini and other web-based AI tools. It is aimed at mid-market organisations and deploys via MDM, with Chrome and Edge named as supported browsers; policies can block a risky action, redirect the user to Copilot or log the action for audit. The vendor positions it as an option for firms without Microsoft Purview E5 licensing and Entra-enrolled Windows devices, and states that the extension does not see native desktop apps such as Claude desktop or Copilot inside Word. Pricing is published: the first 10 licences are free, the Standard plan is GBP 6 per user per month for 11 to 500 employees, and Enterprise pricing is custom. The product is made by Fendr Ltd, incorporated in London on 4 August 2025, with founder Katie Whitlock listed as a director at Companies House. Fendr took part in the LASR Validate programme and was profiled by Plexal in October 2025, when it was running proof-of-concept trials.

PII Crawler is a desktop and command-line scanner from Eligian Labs LLC (Washington, USA) that finds unencrypted personal data in files, network shares and databases on the customer's own hardware.

The vendor's security page documents that no file contents or matches are ever transmitted and that all four optional endpoints (licence registration, update check, error reporting, UI analytics) can be disabled with an --air-gapped flag or offline licence token.
