RAG assistant
A secure company ChatGPT that answers from your documents, contracts and policies, with source citations. Your data stays with you: EU hosting, access control and logging.
SEC // AI Secure AI for Czech businesses
People run your business. Let AI run the routine.
We build AI applications and automations for Czech businesses. We run much of our own company on AI, so we’re not speaking from theory. Secure, and built with NIS2 and AI Act requirements in mind.
Tachys security is built by people who’ve worked in cybersecurity for years.
We build on
Three ways AI will save you time
AI is all we do — and we build it for production, not for the drawer. Security is part of the work from hour one, not an afterthought.
-
Custom AI applications
A bespoke AI tool built around your process: an assistant over your company data, classification, document generation.
RAG · chat · classification -
Process automation
Repetitive routine, from e-mails to invoices, runs on its own. Integrations with Pohoda, ABRA, Shoptet and Czech data mailboxes.
workflows · integrations -
AI-run company as a service
Operations where AI handles as much routine as possible and people keep the decisions. We set up orchestration across your tools and train your team.
agents · operations
Products & services
Concrete services from the first audit through to daily operations. No flashy demos — solutions that keep running after we leave.
AI security audit & compliance
Gap analysis against the Czech Cybersecurity Act (NIS2) and the EU AI Act. Know exactly what to meet and how. Deliverables that hold up in an inspection.
LLM security audit / AI pentest
We test your chatbot or agent against the OWASP LLM Top 10. Prompt injection, data leakage through RAG.
Document automation
Invoices, orders, e-mails and reporting without the manual work. Measurable hours saved, no vendor lock-in.
AI for accounting & law firms
Document data extraction and an assistant over your case files. Turnkey deployment and training, with a full audit trail.
“AI, Securely” training
The AI literacy your team is required to have. Practical use cases, a certificate and a template internal AI policy.
Also available on request: a digital employee (pilot program, always with human oversight) and on-prem LLM deployment for your most sensitive data.
From audit to operations in four steps
No months of analysis. Straight to results you can see in the numbers.
-
1
Consultation & mapping
We walk through your processes and find where AI will deliver the most. The intro consultation is free; the in-depth audit is the START package.
-
2
Solution design
A concrete plan with estimated savings and pricing. You know exactly what you’ll get and what it costs.
-
3
Build & deploy
We build it, integrate it with your tools and test it in real-world operation.
-
4
Operate & improve
We measure impact, fine-tune and add more. You’ll see the time and cost savings in black and white.
We’re not an agency that talks about AI. We’re a company that runs on it.
AI only, and into production
No pretty slides that never ship. We deliver solutions that run in production and save both time and money.
We run on AI ourselves
Much of our own operation runs on AI. On a consultation, we’ll show you exactly how it works for us.
Security is in our DNA
We come from cybersecurity. Your data stays yours. Security is the foundation, not a paid extra.
Clear packages, from an audit to your own AI team
Prices are indicative; the final quote always depends on scope. We don’t bill hours — you pay a fixed price for an agreed scope.

We’re building a company where AI does the routine and people decide — and showing it can work at yours too
Tachys was founded by a cybersecurity professional who kept seeing companies waste time on routine that AI can handle today. We connect your processes, data and AI so they finally add pace to your business — not more work.
Years in IT and security come down to one thing: your data stays yours. We deploy AI so that nothing leaves your company.
“AI already handles a large part of our daily routine. We can set up the same at yours. Securely.”
Straight answers
Three questions you’d ask us anyway. So here are the answers up front.
You’re new to the market. Why should we trust you?
The Tachys brand is new — the team isn’t. Behind it are people who’ve made their living in cybersecurity and IT for years. And we deliberately build first projects as pilots: small scope, fixed price, measurable outcome. You continue only when the numbers make sense.
Where does our data end up?
With you. We build solutions so that data stays in your infrastructure or on EU hosting, with access control and logging. For your most sensitive data, we can deploy an LLM fully on-premise.
Will you guarantee NIS2 and AI Act compliance?
Nobody can seriously guarantee compliance — it’s an ongoing process on your side. What we deliver is a gap analysis, documentation and technical measures you can present in an inspection. And we’ll tell you straight what’s on you.
