Data Loss Prevention

GeoLang delivers data discovery, data extraction and data loss prevention solutions, services and technologies to discover, classify and protect sensitive data and information in the cloud

and on premise

What We Do

GeoLang (a Shearwater Group plc company) uses its cutting-edge Ascema technology to discover sensitive data in an organisation where it rests; and to detect, protect, report and remediate when data moves. This provides companies with a clear picture of their IP and sensitive data, protecting content regardless of whether users change the file type, cut snippets out, or recreate with separate applications.

Ascema Data Discovery

Uses pattern-matching technology to search files at the content level to help you discover data where it rests on your network, and proactively protect it.

Ascema Data Loss Prevention

Classifies, fingerprints and protects confidential and critical information so that unauthorised end users cannot accidentally or maliciously share data.

Professional Services

We offer impartial advice and guidance on cyber security, data management, and policy making for audit and compliance and added security.

How We Do It

GeoLang uses patented, automated technology – Ascema Data Discovery® and Ascema Data Loss Prevention® – that is easy to deploy and proven to protect sensitive information at the content level.


Analysing and irreversibly fingerprinting content within documents and email streams, then indexing and storing the fingerprints (but not the data) in the Ascema vault.

Real-time intelligence

Machine learning to detect content movement as it happens, enforce data policies automatically, and issue remediation for individual data classifications.

Continuous development

Our architects and engineers continuously develop the Ascema technology stack to make sure our solutions are in line with current and future developments.
