-----Who We Are
An IT & Cybersecurity Team
That Works Like Your Own
Most organizations of 20–500 people are forced to choose between one IT hire who cannot cover everything, and a patchwork of consultants where nobody owns the whole picture. Greenwill Solution exists to close that gap: the equivalent of a four-person specialist team — Help Desk, System Engineer, Security Analyst and virtual CISO — under one contract with one accountable owner.
What We Stand For — Honesty
We never promise 100% security, because no system on earth delivers it. What we do is make attacking your organization significantly harder, slower and more expensive — so the vast majority of attackers move on to easier targets. When a client declines a recommendation, we record it transparently in a signed Risk Acceptance Log.
“No system is 100% secure — we make attacking you not worth the effort.”
Your Data Belongs to You — No Lock-In
At contract end we hand everything back in full — asset registers, patch logs, vulnerability findings, incident records, security policies and the Risk Acceptance Log — so a successor provider can take over immediately without re-surveying your estate.
“Clients should stay for service quality — not because they're locked in by their own data.”
The Neutral Third-Party Auditor
For insider threat and DLP work we act as an external, neutral auditor: privilege separated from your internal administrators, an immutable audit trail held outside your estate, and reporting straight to the board — for the case where the people being monitored are the administrators themselves.
“The auditor must not be the audited.”
-----Capabilities
Four Pillars of Service
Across Nine Catalogued Lines
Every service carries a catalogue code, a written scope and an SLA — auditable, tenderable, and built to pass enterprise procurement review.
Managed IT & Security
Your IT team, delivered — patch management, asset inventory, EDR/XDR, SIEM monitoring, vulnerability scanning and incident response, alongside multi-vendor hardware maintenance for every major brand, in and out of OEM warranty.
Compliance & Advisory
Led by a CQI/IRCA ISO 27001 Lead Auditor — gap assessment, ISMS build-out, PDPA governance, and C-level advisory (vCIO / vCISO) without the full-time executive hire.
Monitoring & Backup
See everything, recover anything — Zabbix deployment with Grafana dashboards built for auditors, and NAKIVO backup on a 3-2-1-1 architecture with an immutable repository that not even an administrator can delete.
Supply & Procurement — the Ninth Line
We source hardware and software through authorized distribution — factory-sealed NEW with OEM warranty, or Greenwill Certified REFURBISHED with our own 3-month warranty — plus enterprise AI subscriptions (ChatGPT Business, Claude Team,
Gemini) with full THB tax invoicing

-----Why Organizations Choose Us
What Sets Us Apart from
Every Other Provider
Genuine Multi-Vendor Depth, One SLA, One PO
Dell · HPE · IBM · Lenovo · Fujitsu · EMC · HP · Fortinet · Brocade · VMware · RHEL — all on one contract. Every success story names this as the number-one reason for trusting us.
We Sustain What the OEMs Abandoned
IBM POWER822, xSeries M2/M3, Storwize V3700 and other EOL/EOSL assets still running production — kept alive with parts from our own stocked inventory, at service levels up to 24×7×4h.
We Clear the Strictest Vendor-Compliance Bars
The ISO 27001 · ISO 29110 · CISSP combination has cleared Nokia's vendor-compliance process, overseas parent-company compliance teams, and the vendor-acceptance process of a top-tier Thai commercial bank — with audit trails and change management that financial regulators accept.
Technology Companies Themselves Rely on Us
A global Japanese IT OEM outsources its own spare-parts warehouse and 24×7 SLA to us, while Nokia and AIT embed us in their delivery chain to end customers.
A Four-Specialist Team for Less Than One Hire
Benchmarked against one IT employee at ฿40,000–65,000/month, a market CIO at ฿2–4M/year and a CISO at ฿3–6M/year — you get Help Desk through vCISO for less.
We Hand Over Platforms, Not Boxes
Zabbix + IoT integration + Grafana delivered with on-the-job training, so your own team can genuinely own the system after handover instead of depending on us forever.
Commercial Flexibility
OPEX rental · one-time install · annual MA · 3-year bundles · per-incident · standby retainer · parts-only · and Pay-per-Success, where you're billed only for devices successfully hardened.
Fluent in Japanese-MNC Operating Culture
Bilingual reporting, an audit trail the HQ can inspect, and conservative change control — proven across Fuji Seal, Yoshino, Sumisho, Yamato Esulon and Fujitsu.
Local Commercial Convenience
Proper THB tax invoicing, Thai-language support, a single point of contact for foreign SaaS and AI subscriptions, a 12-month price lock against FX movement, and 30-day renewal notice.
Regional Reach Beyond Thailand
Cross-border parts delivery into Lao PDR and to ASEAN integrators, with lead-time management, warranty handling and customs documentation.
