Below is a concise, up-to-date comparison of the leading global IT solutions/providers (status as of Sept 24, 2025). I focus on market position, core strengths, typical customers/use-cases, scale (revenue/brand rankings where available), and quick pros/cons — so you can pick providers by the problems you need solved.

Important note: rankings and metrics change frequently (quarterly/annually). The brand-value / market-position data cited below are drawn from industry reports and news published in 2024–2025 (sources cited after each provider). If you want a custom shortlist (by region, budget, cloud-first, MSSP, managed services, SMB vs enterprise), tell me and I’ll refine it.

If you want next steps

• I can create a 3–5 vendor short list tailored to: your industry, project type (cloud migration, app modernization, GenAI PoC/production, managed security, SAP), budget, and required geography — and show a one-page RFP criteria matrix to evaluate them.
• Or I can export an ordered comparison (cost ballpark, project fit, risk factors) for any three vendors you name.

Which format would you prefer next: short RFP matrix, shortlist by use-case, or vendor pros/cons expanded into a one‑page brief?
