Repatriating Your Data to Europe.
Bytsecure was founded with a clear goal: to return control of data where it belongs — to your infrastructure. We never hold client data. The only thing we keep is your billing record.
25 Years on the Front Line
From 2001 in Thessaloniki — to today, protecting the data of Greece's largest organizations.
Founded
IT services in Thessaloniki — we start with Greek businesses.
Specialization
6 years serving municipalities and public organizations — understanding the unique needs of local government.
The Realization
The rise of ChatGPT reveals the problem: organizations are sending data to the US without knowing it.
NIS2 & Bytsecure
NIS2 takes effect. Bytsecure is born as a digital sovereignty platform.
The Ecosystem
5 services — AI, Office, PDF, SIEM, OpenGov. All on-premise or EU cloud.
Why We Exist
Greek organizations are trapped between the need for AI and laws that prohibit US cloud. Bytsecure bridges this gap: we deliver all the power of AI, without sacrificing sovereignty.
The Problem We Saw
Why Greek organizations need an alternative.
US Cloud Dependency
Microsoft 365, Google Workspace, ChatGPT — all store data on US servers, exposed to CLOUD Act and FISA.
Schrems II (2020)
The EU Court ruled transatlantic data transfers illegal. Organizations using US cloud are legally exposed.
Training Without Consent
ChatGPT, Claude, and Gemini use your corporate data to train their models — without asking.
Vendor Lock-in
Leaving Microsoft/Google is technically difficult, time-consuming, and expensive. We use 100% open source — the exit is always open.
Our Values
Six principles that guide every decision and every line of code.
Data Sovereignty
Your data is your most valuable asset. It doesn't belong to us, or to any third party.
European Identity
We build exclusively on European infrastructure. GDPR, NIS2, EU AI Act are our principles — not obstacles.
Open Source First
100% of our code is open (AGPL). Audit it, modify it, improve it. Zero vendor lock-in.
On-Premise by Design
Every service is designed to run on your infrastructure. The cloud is an option, not a default.
Zero AI Training
We never use your data for model training. Models are pre-trained — your data stays yours.
Human Oversight
Critical decisions require human approval. AI proposes — humans decide.
What Makes Us Different
Compared to the traditional solutions organizations use today.
