Most enterprises believe their internet perimeter is a uniform security problem. In reality, the risk is sharply concentrated: a small slice of unknown, unmanaged assets carries nearly all the danger, while the vast majority of the surface is well-protected.
SixMap assessed 100 enterprise organizations and found that 99.63% of service exposures carry zero known CVEs — but just 1.5% of hosts account for 99% of all vulnerabilities, with CVE density running 270× higher than average. Nearly two-thirds of organizations have a host with an actively exploited CISA KEV-listed vulnerability sitting undetected on their perimeter.
The root cause isn’t slow patching — it’s asset blindness. Security teams can’t protect what they don’t know they own. Download the full report for the complete data, a Fortune Global 500 case study, and a framework for closing the visibility gap before attackers exploit it.
