Verticals

Overview

Security Consulting & Advisory covers the strategic and technical advisory services that help organizations assess, design, and improve their security — risk assessments, compliance (SOC 2, PCI, HIPAA), security strategy, virtual CISO services, and program development. It spans the security practices of the big consultancies (Deloitte, PwC, EY, Accenture, Mandiant) and a large base of boutique security advisors.

Demand is driven by regulatory complexity, board-level security attention, the talent shortage (driving virtual-CISO and advisory demand), and the need to navigate an overwhelming vendor landscape. It is a fragmented, expertise-driven services category consolidating around scaled advisory firms and a steady private-equity roll-up theme, with compliance and virtual-CISO services especially in demand.
