Public-facing CISOs are the buyer persona cybersecurity vendors are marketing to. Listing them with a speaking, publishing, or advisory track record helps marketers identify credible advisory board and customer-reference candidates. ### What makes a CISO 'public-facing'? A track record of conference talks, published commentary, podcast appearances, or advisory roles, not just holding the CISO title at a company.
