The perimeter didn’t disappear
Internet-facing infrastructure remains a primary point of compromise even as security programs increasingly focus on internal detection and response. External assets are continuously scanned and probed, often before vulnerabilities are formally disclosed. At the same time, security teams are overwhelmed by signal noise: the vast majority of scanner findings never translate into real-world risk, creating operational friction without improving certainty. Meanwhile, foundational infrastructure such as DNS continues to represent a significant share of confirmed exposure.
These conditions create a structural mismatch between attacker behavior and defensive practice. Exploitation is accelerating at the edge while validation remains periodic and inconsistent. Many organizations still test critical assets monthly, quarterly, or even annually, leaving long windows where external exposure goes unverified. When attackers can begin exploiting weaknesses before a CVE is issued, workflows tied to disclosure cycles and patch calendars inevitably lag behind active threats.
Security programs increasingly need to align validation with adversary speed rather than internal schedules. Continuous verification of the external attack surface—focusing on exploitability rather than theoretical risk—enables teams to reduce false urgency, prioritize remediation where it matters most, and close exposure gaps before they become entry points.
What you'll find in The perimeter didn’t disappear report
- Only 0.5% of vulnerability scanner findings represent real-world risk, meaning the vast majority of alerts consume security resources without improving confidence in exposure prioritization. This imbalance pushes teams toward validation approaches that emphasize exploitability rather than raw alert volume.
- DNS infrastructure accounts for 23% of verified external exposure, making it the single largest category of confirmed perimeter risk. Securing DNS alone can prevent more than 33% of cybersecurity breaches, highlighting a high-impact remediation opportunity for security teams.
- Evidence of active exploitation now appears on or before CVE publication in 32.1% of known exploited vulnerabilities, up from 23.6% the year before. Disclosure is increasingly a lagging signal rather than the start of attacker activity.
- Testing frequency for critical assets varies widely across organizations—27% validate daily while another 27% test only annually—creating inconsistent protection and long periods of unverified exposure across external attack surfaces.
