represent, "new directions in their market spaces," Gartner defined

Alto Networks' Vice President of Marketing. "Internet applications and
associated threats are evading existing firewalls and security
infrastructure, and Palo Alto Networks' innovative PA-4000 Series

IT back in control of what comes in and out of their network with
visibility and granular control of applications and threats."
