In 2025, finding reliable IT partners who truly understand the expectations of Japanese and Korean enterprises has become increasingly challenging. Rising development costs, prolonged hiring timelines, and a growing shortage of skilled engineers are pushing companies in Japan and South Korea to rethink how they scale their technology teams. At the same time, strict requirements around security, data protection, system stability, and long-term maintainability leave little room for error when choosing an outsourcing partner.
Language and communication gaps, differences in work culture, and concerns over quality control often make offshore outsourcing feel like a high-risk decision for Japanese and Korean businesses. Many technology leaders are searching for a model that offers not only cost efficiency but also reliability, transparency, and a development mindset aligned with Japanese and Korean standards.
This guide leverages GITS’ hands-on experience working with clients across Japan and South Korea to help you identify the top IT companies in Vietnam for 2026—partners capable of delivering high-quality engineering, stable operations, and long-term value, turning your IT challenges into sustainable competitive advantages.
Why choose IT companies in Vietnam
Significant figures
When you’re deciding where to outsource your next critical project, the data tells a compelling story about Vietnam. The ICT market is projected to reach $9.12 billion in 2025 and is growing at nearly 10% annually, while IT outsourcing revenues alone are expected to climb from $0.83 billion in 2025 to $1.28 billion by 2026.
But it’s not just about market size—it’s about what that growth means for your business.
Addressing key challenges for Japanese and Korean enterprises
Challenge 1: Securing stable, high-quality engineering talent
For companies in Japan and South Korea, the challenge is not simply a lack of engineers, but the difficulty of securing teams that can deliver consistent quality over time. Vietnam offers a large and steadily growing pool of software engineers educated through a structured university system, with strong fundamentals in system design, development, and problem-solving. This makes it possible to form long-term development teams rather than rely on short-term hiring solutions.
Challenge 2: Balancing cost efficiency with quality
While cost is an important consideration, Japanese and Korean enterprises rarely compromise on quality or delivery stability. Vietnam provides a competitive cost structure compared to Japan, South Korea, and other outsourcing destinations, while maintaining strong engineering standards. This balance allows companies to allocate resources more effectively focusing on system improvement and scalability instead of escalating development costs.
Time zone advantages often overlooked
For businesses in the Asia-Pacific region, Vietnam offers same-day collaboration. For European and North American companies, the time difference enables a “follow-the-sun” development model—your team works while your offshore team sleeps, and vice versa, effectively giving you 24-hour productivity cycles.

But what’s driving this explosive growth, and more importantly, what does it mean for your business in 2026?
Key trends shaping 2026
AI integration is Accelerating
Vietnam’s AI market is expected to reach $753.40 million in 2025, with a growth rate of 28.36%. NVIDIA’s announcement of two AI research hubs in Vietnam signals major tech giants’ confidence in the market. Vietnamese companies aren’t just following AI trends—they’re leading them.
Digital Economy Boom
The digital economy is on track to hit $43 billion, with annual growth of 20% continuing through 2025. This isn’t speculative—it’s happening right now, creating opportunities for early-mover advantage.

What’s different in 2026?
Shift from Cost-Cutting to Value Creation
Only 34% now cite cost reduction as their primary outsourcing reason, down from 70% in 2020. This reflects a mature market where quality, innovation, and strategic partnership matter more than just cheap labour.
Nearshore Preference Growing
Companies now prioritise proximity, data residency, and communication over lowest cost. Vietnam’s geographic position makes it ideal for nearshoring to Asia-Pacific markets while remaining cost-effective for Western markets.
Focus on Strategic Partnerships
The shift is from transactional outsourcing relationships to strategic partnerships. Vietnamese companies are no longer just coding to specs—they’re driving innovation and taking ownership of outcomes.
Key criteria for selecting the best IT outsourcing partner
Choosing an IT outsourcing partner isn’t just about finding someone to write code—it’s about finding a strategic ally who understands your business, communicates effectively, and delivers results. Here’s your practical framework for making the right choice:
1. Technical expertise and proven track record
Look for partners with portfolios showcasing completed projects in your industry, client testimonials with measurable results, and technical certifications like ISO 9001, ISO/IEC 27001, or CMMI. Red flags include vague project descriptions, inability to provide client references, and generic portfolios. Ask key questions like “Can you show me three projects similar to what we need?” and “What were the measurable outcomes and ROI for your clients?” A strong partner should confidently showcase complex projects and connect you with satisfied clients.
2. Communication and cultural fit
For Japanese and Korean companies, communication reliability, time zone alignment, and cultural compatibility are often more important than cost. Choose partners with experience working with JP and KR clients, stable availability during business hours, and clear, structured communication. Starting with video meetings and a small pilot project helps assess responsiveness, work discipline, and cultural alignment—key factors for building a long-term, trusted partnership.
3. Security and compliance standards
With cybersecurity ranking among the most outsourced IT functions at 77%, security is non-negotiable. Must-have features include ISO/IEC 27001 certification, GDPR compliance for European clients, data encryption, secure development practices, NDAs, IP protection clauses, regular security audits, and incident response procedures. For regulated industries, verify industry-specific certifications like HIPAA for healthcare or PCI DSS for finance, along with data residency options and clear privacy policies that meet your compliance requirements.
4. Domain knowledge in your industry
Generic development shops can code, but partners with industry expertise can consult, challenge assumptions, and suggest better approaches. For FinTech, look for experience with payment gateways, regulatory compliance, and security standards. Healthcare requires HIPAA compliance, EHR integration, and telemedicine platform development. E-commerce demands payment processing, inventory management, and scalable infrastructure expertise. Manufacturing needs IoT integration, supply chain optimisation, and predictive maintenance capabilities. Industry-specific knowledge transforms vendors into strategic advisors.
The bottom line: Vietnam in 2026
The IT outsourcing landscape is changing. Cost savings alone no longer drive decisions—it’s about finding partners who become extensions of your team, understand your business challenges, and deliver innovation at scale.
Vietnam’s IT ecosystem has matured beyond being just a cost-effective alternative. With top-tier technical talent, strong communication, robust government support, and a rapidly growing digital economy, Vietnamese IT companies are positioned to be strategic partners for global businesses navigating digital transformation.
The companies on this list represent the cream of the crop—proven track records, global client bases, cutting-edge technical capabilities, and the infrastructure to support projects of any scale.
