Arceris Labs builds Arceris (arceris.ai), a self-hosted AI security gateway for regulated organizations. It routes all AI traffic — browser, terminal and API — through one on-premise control point. Your DLP can't see the chat box. It was built for files and email, and it does not read what an employee types into ChatGPT, the document they attach, or the answer that comes back. Arceris does — before any of it leaves your network. It sits between your people and public LLM providers and applies one policy set at every door: sensitive data is detected and masked, prompt injection and unsafe content are blocked, uploaded files are inspected, and each team's model access and spend are enforced. All of it logged for audit. Deployed on-premise or fully air-gapped. No prompt leaves the organization's network. We are an applied security lab: we build the control layer that lets regulated organizations adopt AI without surrendering their data — inside the perimeter, auditable end to end, sovereign by default.
