Vertali is a UK-based IT services company specialising in IBM Z (mainframe) consulting, security, and workforce development. The company serves organisations across the UK, Europe, and Asia-Pacific, with clients operating in financial services, retail, utilities, and government - sectors where mainframe infrastructure remains critical.
The company's core offering is senior IBM Z consulting: experienced professionals work alongside client teams to reduce operational risk, optimise mainframe environments, and help define and execute mainframe strategy. Vertali holds ISO 27001 accreditation and Cyber Essentials certification, and provides security advisory services aligned with recognised compliance standards.
A distinctive part of Vertali's work is its New To Z initiative - a structured five-year programme through which practising consultants mentor and develop the next generation of mainframe professionals. The programme combines hands-on experience with formal knowledge transfer, reflecting a broader organisational emphasis on skills continuity in a field where expertise has been built over decades.
Vertali screens its consultants for both technical depth and the ability to work effectively with stakeholders across all levels of an organisation. The company places stated emphasis on integrity, technical excellence, and clear communication as operating principles.
