Sealforge Anonymizer

Anonymize production data for your development and test environments, and remove personal and confidential data before it reaches an AI.

The Sealforge Anonymizer removes personal and confidential data from prompts, files, tool calls and data sets before they leave your control.

Use cases

  • Realistic data for non-production environments — anonymize copies of production data before loading them into development, test, staging or training environments, so teams work with realistic data without exposing real people or confidential information.
  • Working safely with AI — prompts, documents and tool calls are anonymized before they reach ChatGPT, Copilot, Claude or any other language model.

Self-hosted: on your machines and infrastructure

Your data never leaves your network; only the license check reaches Sealforge, and it carries no data.

Self-hosted Anonymizer Inside your infrastructure, the command-line tool anonymizes production data for development and test environments, the MCP server and LLM proxy anonymize prompts before they reach AI models, and the self-hosted API anonymizes data for your applications. Only a licence check, carrying no data, reaches Sealforge.

  • Command-line tool — anonymize files and exports in scripts and CI pipelines, for example before copying production data into a test environment.
  • MCP server — AI assistants such as Claude or Copilot receive anonymized documents and tool results.
  • LLM proxy — sits between your applications or teams and the language model provider, on a workstation or on a server shared by a team.
  • Anonymizer API, self-hosted — the same engine as an HTTP API, deployed next to your own applications and pipelines.

Hosted by Sealforge

Hosted Anonymizer API Your applications send data with their licence key over HTTPS to the Anonymizer API hosted by Sealforge, which returns the anonymized result and keeps nothing. YOUR INFRASTRUCTURE SEALFORGE CLOUD Your applications pipelines, services Anonymizer API hosted · nothing kept data + licence key (HTTPS) anonymized result
  • Anonymizer API, hosted — call it with your licence key from your applications, with nothing to install or operate. Data is anonymized on Sealforge's servers and none of it is kept.

Licensing

The Anonymizer API is included in the Data Masking plan: each key serves one machine (command-line tool, MCP server or LLM proxy), one caller of the hosted Anonymizer API, or one self-hosted Anonymizer API deployment. The AI plan licenses the command-line tool, MCP server and LLM proxy, per machine.
