The entire solution is built entirely on the company's infrastructure (On-premise) and can operate with an independent storage system (Air-gapped). This is the optimal model to ensure data sovereignty, privacy and eliminate dependence on third-party Cloud providers thanks to 100% autonomy from hardware to software.
Many SME businesses are still paying for licenses without knowing there are completely free and better security alternatives.
Windows 11 Pro ~4,500,000 VND/computer. Microsoft 365 Business Standard ~3,900,000 VND/user/year. 50 employees = more than 200 million/year just to use Word and Excel — and cannot stop renewing if you don't want to lose your ability to work.
Windows is the most attacked platform — more than 95% of ransomware targets Windows. Business antivirus adds ~500,000 VND/computer/year. Linux has a fundamentally better security architecture, no need for paid antivirus.
After 1–2 years of use, Windows accumulates junk and slows down noticeably. Employees spend 5–10 minutes waiting for boot, software crashes, and Windows updates when they don't want to. Linux maintains stable performance throughout the life of the machine.
Linux LTS provides a complete work environment for all office, accounting, design and engineering positions.
LibreOffice is a full office suite that replaces Microsoft Office — read, write, and edit fully compatible with .docx, .xlsx, .pptx without font or format errors.
Linux architecture decentralizes users from the core — viruses cannot run in the background or spread without root permissions. Most Windows malware does not affect Linux.
Linux is 30–50% lighter than Windows in idle RAM. An 8 GB RAM machine runs Linux as smoothly as a 16 GB RAM machine running Windows 11. Performance does not degrade over time.
Thunderbird completely replaces Outlook — supporting multiple accounts, Exchange, IMAP/SMTP, calendar, tasks, and email encryption. Or use a browser with Gmail/Outlook Web.
Open source design toolset that rivals paid software — from photo editing and graphic design to professional video editing and color management.
Manage dozens of employee computers remotely via SSH, Ansible or web interface — update, install software, and check the security of the entire fleet without needing to be on-site.
Employees switching to Linux don't have to give up the tool — just use the free equivalent, which is often better when it comes to security.
Open, edit, save fully compatible Microsoft formats
Connect to all email and online conferencing services
Completely free professional creative tools
High-performance browser, compatible with all web applications
All the software you need for your business — from office and accounting to programming and system administration.

Linux is not a "cheap alternative". This is the operating system that runs 95% of internet servers, banking systems, and Android devices — because it's actually technically better.
8 GB RAM, 4 year old CPU computer runs Windows 11 slowly — but runs Ubuntu Linux smoothly. Instead of buying a new machine, just reinstall Linux to get another 3–5 years of use.
GNOME Desktop (Linux's most popular interface) is very intuitive — non-IT employees usually get used to it in 1–2 days. LibreOffice has an interface similar to Microsoft Office 2019.
MISA, FAST Accounting, VN-Invoice all have web versions or can be run via Chrome/Firefox browser on Linux. Not tied to Windows to use domestic software.
Ubuntu LTS 24.04 is securely supported through 2029 (free) and 2034 (with free ESM for individuals). There is no pressure to buy new Windows after 2031.
Comparison for 50 employee computers, 3 years of use
* Only software licenses are counted. Implementation and training costs are calculated separately and are usually paid back in 1–3 months.
"We have 60 computers paying for Windows + Microsoft 365. After switching to Linux, we saved more than 250 million/year. Accounting and sales staff got acquainted with LibreOffice in 3 days of training — no one complained."
"Since switching to Linux, 0 virus infections in 2 years. Before that, every year there were at least 1–2 machines encrypted with ransomware. Saving not only antivirus fees but also recovery time and lost data."
"Our employee's computer is an 8th generation Core i5, 8 GB RAM — Windows 11 runs very slowly. After installing Linux Ubuntu, the computer runs as fast as new. Saved the cost of buying 30 new computers — equivalent to more than 300 million VND."
The transition is done in small batches — it doesn't affect the entire company at once, giving employees time to adjust step by step.
Evaluate the software employees are using, determine which software can be replaced with Linux and which software needs to run in parallel or over the web.

One-time payment for installation and training service. After that, no more annual Windows, Office or antivirus fees.
Test Linux in your enterprise with 5–15 machines before full deployment. Evaluate actual feedback.
Complete deployment for 20–100 machines, centralized administration via Active Directory/LDAP and full training.
100+ machines, multiple offices, existing ERP/CRM system integration and centralized enterprise software management.
✦ Commitment to transparency: No Windows fees. No Office fees. No antivirus fees. After deployment, every computer runs completely royalty-free — forever.
