Why Do Organizations Need Attack Surface Management?

Businesses are accelerating faster than the growth of their security teams.

Attack surfaces are expanding 110% year over year, but for every 100 developers within an organization, there’s typically just one dedicated security function. Digital transformation and the rise of Shadow IT adds to this complexity, which in turn increases threats and risk to the organization.

The reality is that attack surfaces have grown beyond the scope of what traditional security tools and practices can effectively manage. Many security professionals are simply unable to comprehensively discover, manage, and protect their rapidly growing attack surfaces.

Attack Surface Management addresses this gap as a forward-looking solution that can broadly, deeply, and relentlessly search and monitor an organization’s digital footprint, identifying and rating risks, and recommending clear remediation actions.
