In the AI era, that outcome isn't aspirational, it's essential,\u201d said Benny Lakunishok, CEO and Co-Founder of Zero Networks. \u201cBoards are demanding uptime and answers, and this data helps CISOs deliver. For the first time, risk leaders can benchmark their network security against the reality of hundreds of live enterprise environments and see precisely where they stand. But you cannot contain what you cannot see. That's why we built Breach Map: to expose every open lateral movement path in your environment, so you can close it before an attacker walks through it.\u201d<\/p><p>The data illustrates how far most enterprise networks leave the door open once attackers get inside.<\/p><p><b>Key Findings<\/b><\/p><p>The 2026 Lateral Movement Exposure Report identifies eleven lateral movement risks across enterprise environments. Key findings include:<\/p><ul class=\"bwlistdisc\"><li>Roughly 80% of enterprises have already deployed internal AI agents, yet two-thirds lack governance policies for them \u2013 creating rapidly expanding unmanaged attack surfaces.<\/li><li>87% of enterprise servers accept inbound RDP or SSH connections from broad internal sources, giving attackers wide access pathways once inside the network.<\/li><li>78% of enterprise servers are reachable over SMB or WinRM, the same administrative protocols attackers commonly exploit for ransomware spread and lateral movement.<\/li><li>43% of internal authentication traffic still relies on NTLM, a legacy protocol frequently abused for credential replay and privilege escalation attacks.<\/li><li>12% of organizations maintain direct user-to-server administrative pathways, meaning a single compromised employee device can provide immediate access to high-value systems.<\/li><li>The research shows most enterprise environments still allow breaches to spread too easily after initial compromise \u2013 a risk amplified significantly by AI-driven attack automation.<\/li><\/ul><p>You can download the Zero Networks 2026 Lateral Movement Exposure report <a  href=\"https:\/\/cts.businesswire.com\/ct\/CT?id=smartlink&amp;url=https%3A%2F%2Fzeronetworks.com%2Fresource-center%2Freports%2F2026-lateral-movement-exposure-report%3Futm_medium%3Dpr%26utm_source%3Dzero_networks%26utm_campaign%3Dlmer_and_blast_radius_tool_pr&amp;esheet=54550953&amp;newsitemid=20260610811373&amp;lan=en-US&amp;anchor=here+%E2%86%92&amp;index=270&amp;md5=042ebb122cf02c5a589b7be06788f100\" rel=\"nofollow\" shape=\"rect\">here \u2192<\/a><\/p><p>\u201cThe industry spent years focused on keeping attackers out,\u201d said Dmitri Alperovitch, Co-Founder of CrowdStrike and current President of Silverado Policy Accelerator. \u201cBut in the AI era, the biggest question facing defenders is what happens after they get in. This report shows most enterprises still have enormous internal blast radius, and that should concern every board, CIO, and CISO. The organizations that adapt fastest will shift from perimeter-only thinking to containment: limiting lateral movement, reducing blast radius and ensuring attacks cannot bring down a business.\u201d<\/p><p><b>About Breach Map<\/b><\/p><p>To help security leaders act on the report's findings, Zero Networks is simultaneously launching Breach Map \u2013 a free tool that maps an organization's internal attack surface and shows exactly how far a breach could travel using privileged ports.
