Secure ChatGPT that stays under your control
Your AI chat interface. Your data. Your rules. Deploy Open WebUI in minutes and get the exact ChatGPT experience without sending prompts to OpenAI. GDPR compliant. Zero per-user fees.
Why Opsily for secure ChatGPT
Security is not an afterthought. It is the architecture.
Your data never trains models
Every conversation stays on your private instance in Frankfurt, Germany. No prompts sent to OpenAI's infrastructure. Your data is not used to train or improve any model. Full audit trail for compliance teams.
GDPR compliant by design
EU-hosted infrastructure. Encrypted backups. Automated compliance logging. No data residency tricks. When you ask Open WebUI a question, every bit of that request stays within EU borders. GDPR officers sleep.
Costs drop when you add users
ChatGPT Enterprise charges $30 per user per month (minimum 100 seats, then negotiation). Our Large plan is EUR70/month for unlimited users. Ten team members, fifty, two hundred: same price. Budget predictability.
Built for teams who need reliability

Why ChatGPT alone is not secure for enterprises
OpenAI's terms allow them to review content to improve models and detect abuse. That means confidential documents, code, customer data, anything typed into ChatGPT can be viewed by OpenAI staff and potentially used to refine the model. For legal teams, healthcare, banking, or regulated industries: that's a compliance nightmare.
A self-hosted alternative like Open WebUI running on Opsily solves this. Your infrastructure, your rules.
What "secure" means in this context
Data residency: All requests, responses, and conversation history live in Frankfurt, Germany. No US-based cloud provider can access it. Full GDPR Article 32 compliance (confidentiality, integrity, resilience).
No model training: Open WebUI never sends your data anywhere. Whether you use OpenAI's API, Anthropic's Claude, or local Ollama models, the wrapper is yours.
Encryption in transit and at rest: Opsily provides TLS for all traffic. Daily encrypted backups (7-30 days depending on plan). Access logs for audit.
Role-based access control: Assign permissions: who can see what, who can delete conversations, who is admin. Revoke access instantly.
Real-world use cases
Legal teams: Ingest contracts into RAG without sending them to Anthropic or OpenAI. Analyze case law privately.
Healthcare: Process patient notes in a HIPAA-aligned way. Data never leaves your VPC.
Financial services: Run proprietary trading logic and models. No third-party inference.
Government contractors: Comply with ITAR and CMMC by proving data residency with audit logs.
Product teams: Debug with real customer data without exposing it to Langchain or other third-party services.

How to deploy, manage, and stay compliant.
ChatGPT is a SaaS tool owned by OpenAI. Your prompts go to OpenAI's servers. Opsily is a hosting provider that runs Open WebUI, an open-source interface, on your own private instance in Frankfurt, Germany. Your data never leaves your infrastructure. You control the API keys, the data access, the backups, and the compliance audit trail. ChatGPT is convenient but not private. Open WebUI on Opsily is both.
