Frequently asked questions

Tetra Software (Tetra Software Company LTD, based in Ho Chi Minh City) is a Vietnamese technology company building business software, cybersecurity and AI applications for enterprises. What sets it apart: every solution runs on the customer’s own infrastructure (on-premise/self-host), data never leaves your systems, and there is no foreign-vendor lock-in.

Three pillars: (1) Digital transformation — business software, digital workplace, system integration; (2) Cybersecurity — protecting web/API apps and infrastructure; (3) AI for business operations — digitization, data extraction and automation with on-premise AI.

Tetra eOffice (digital workplace), Molly (on-premise AI digitization & data extraction), Otter Test (internal training & assessment, MIT open source), Orca WAAP (web & API protection), Manta Security (device & network security management), Goby Care (service-center & repair management), Remora (a travel router that protects devices on public networks) and Angler (a local search + crawl gateway for research & AI agents, MIT open source).

Yes. Tetra prioritizes on-premise/self-hosted deployment on the customer’s own infrastructure; the AI also runs locally. Your data stays in your systems, meeting data-sovereignty needs.

Tetra focuses on large enterprises and corporate groups, alongside public-sector organizations with strong data-sovereignty requirements — including commune- and provincial-level agencies now accelerating digitization. Solutions are customized to real operations, run on-premise on your own infrastructure, and make use of existing systems such as Microsoft 365 rather than forcing a replacement. Delivery follows a consultative model: survey the current state, design for your needs, and stay with you through to stable operation.

A unified digital workplace: official dispatch per Decree 30/2020, document management with AI search, drag-and-drop BPM workflows, digital signing via VNPT SmartCA, Viettel MySign and MobiFone HSM, tendering under the 2023 Bidding Law, and integration with your existing HR system (HRMS). Deploy on-premise or in the cloud; it can leverage Microsoft 365 (Entra ID + SharePoint) for large customers or run standalone (Authentik + MinIO).

It is not SaaS. Tetra eOffice is customized to each client’s workflows, sold through consultation, delivered in 3–6 months, starting from roughly 300 million VND. You start by booking a consultation/demo, not by signing up.

Molly is a standalone product that digitizes documents in bulk into structured data using on-premise AI (local models), so data never leaves your network. It is digitization and data extraction, not a question-answering chatbot.

Internal training and assessment software for HR: question banks, role-based assessments that staff can retake until they pass, and certificates on passing; the AI can draft questions from your documents (bring your own provider/model). MIT open source (free to use); setup is around 3 million VND, with day-rate development for customization.

A self-hosted WAAP (WAF + anti-DDoS + bot mitigation + API protection) with a ready reverse proxy. The binary and docs are free; support plans start at 1 million VND/month (minimum 3 months) with automatic rule sync and operational support.

Manta Security is Tetra’s security product line, bringing endpoint device management and internal network monitoring and security into one platform: device inventory and status, traffic monitoring and alerts on unusual access. It runs on your own infrastructure (self-host/on-premise), so monitoring data never leaves your systems. Manta complements Orca WAAP (web app and API layer) and uses Remora Router as the endpoint for remote staff.

Remora Router is a secure travel router in the Manta Security line. Connected to public WiFi, it gives you a protected private WiFi: devices hidden behind a firewall, encrypted DNS, ad-blocking and optional full VPN into the company network, with nothing to install on the device. Remora is for organizations equipping their staff, not sold at retail; the Lite model is available and the Pro model with 3G/4G/5G is coming soon.

Software to manage service centers and repairs: intake, progress tracking, parts and customer management. Open source (MIT license). Model: a one-time setup fee plus day-rate development.

Angler is a local-first search + crawl + research gateway that runs entirely on your machine: send a query or URL and get back clean markdown — even from pages behind Cloudflare — ready for research or for an AI agent to use. Its strengths are diverse source gathering (academic sources too), bias-resistant research (/research) and Firecrawl-SDK compatibility — in other words, a self-hosted Firecrawl alternative, great for market research, information gathering and feeding data to AI agents/RAG. Angler is also web access for AI agents / coding agents: Claude Code, Cursor, Codex CLI, Gemini CLI, Cline and more call it over MCP (Model Context Protocol, via the Firecrawl MCP server) or the Firecrawl SDK to search and read the web — just point FIRECRAWL_API_URL at Angler. Angler is a Firecrawl-compatible REST API (it does not speak MCP itself); paired with the Firecrawl MCP server it becomes a self-hosted web-search / web-scraping MCP server. Angler is free and open source under the MIT license; you self-host it with Docker, no API key, and your queries never leave your machine. Get it at github.com/tetravn/angler-crawl.

Yes. Tetra automates repetitive office processes for large enterprises and the public sector: software robots do the rule-based work, and in-house AI handles the reading, such as documents, classification and summaries. Robots and models run on your own infrastructure. Tetra builds and operates the automation long term, with no platform licence fees. Typical first processes: inbound invoices, recurring reports from several systems, bank reconciliation and data entry after scanning. Details: https://tetra.vn/en/solutions/business-ai/process-automation

Tetra does not charge per robot or per licence. There are four packages: an automation assessment (1–2 weeks, fixed fee credited against implementation), a 30-day AI Pilot on one process, implementation priced per process and complexity, and monthly operation priced by live processes and service level. A firm quote follows the assessment.

Yes. For example, Tetra eOffice handles official dispatch per Decree 30/2020, tendering under the 2023 Bidding Law, and digital signing via VNPT SmartCA, Viettel MySign and MobiFone HSM. Vietnamese UI with support in Vietnam.

The Personal Data Protection Law (effective 01/01/2026) and the AI Law (effective 01/03/2026) impose stricter requirements on where personal data is stored and processed and how AI is used. Because every Tetra solution runs on-premise on your own infrastructure, personal data and sensitive documents need not leave for a third-party or overseas cloud — making compliance easier. Tetra advises on a deployment that fits your operations; ultimate compliance responsibility remains with your organization.

Tetra's partners are MobiFone (business & deployment), Titan Technology (software development) and Carp Tech (technology — data warehouse). Digital transformation projects we can share include an e-commerce site integrated with MISA accounting for Binh Hoang and IT infrastructure plus a corporate website for VIES.

Yes. tetra.vn supports WebMCP (Web Model Context Protocol) — the site declares tools that in browser AI assistants can call directly instead of scraping the interface. Read only tools are available: get Tetra knowledge, list products, search the blog, get the current page and navigate. The standard is early and runs where the browser supports it; no personal data is collected.
