Investment Banks & M&A Advisors
Cybersecurity M&A runs through a competitive set of investment banks and advisory firms. Mapping who advises whom underpins buyer/seller analysis and competitive positioning in the advisory market.
The drill-down pages cover the field in detail: The Cyber M&A Advisory Landscape sets out the three advisor tiers by deal size and how each is compensated; How Sell-Side & Buy-Side Processes Run walks the two process types stage by stage, with timelines and artifacts; The Advisor Roster names the firms in each arena (bulge/elite, tech mid-market, cyber specialists) and their strengths; and The Cyber Advisor League Table is the maintained data layer of volume leaders and mid-market/cyber-specialist activity (AGC 28 deals in 2025; Houlihan #1 tech volume; Solganick-tracked 105 cyber deals in Q4 2025).
