Exploiting vulnerabilities has become the most common entry point for attackers, according to recent industry reports. Security vendor Zero Networks attributes the trend to AI-assisted analysis tools and argues that proactive containment should take precedence over traditional patch cycles.
Exploiting vulnerabilities has become the leading method attackers use to gain initial access to corporate networks, according to several recent industry reports. Mandiant’s M-Trends 2026 report attributes 32 percent of initial infections to exploits. In Verizon’s 2026 Data Breach Investigations Report (DBIR), vulnerability exploitation enabled initial access in 31 percent of analyzed incidents, a 55 percent increase over the previous year.
Security vendor Zero Networks links this trend to the emergence of AI-driven vulnerability research tools that, according to the company, can identify, analyze and generate exploits at a speed and scale human teams cannot match. OpenAI has separately urged CISOs to implement network segmentation. IBM’s “Cost of a Data Breach 2026” report quantifies the financial impact: AI-driven attacks reportedly add roughly one million US dollars to the average cost of a data breach.
Kay Ernst, Director DACH at Zero Networks, says these dynamics are putting traditional vulnerability management workflows under strain. As the volume of released patches grows, the window between discovery and exploitation of a vulnerability shrinks toward zero, while security teams must still maintain system availability. Ernst argues that organizations should therefore prioritize proactive containment over patch speed alone.
Zero Networks points to identity-based microsegmentation as one approach: it limits the access scope of a compromised system, giving teams more time to test patches before deployment without leaving organizations exposed to unpatched vulnerabilities in the meantime. The company’s own Breach Map tool is designed to help identify vulnerabilities and targeted mitigation options.
Among the best practices the company recommends: measuring blast radius to prioritize by business risk rather than CVSS score alone, locking down unnecessary access paths by default through microsegmentation, applying targeted access rules while patches are validated, and ensuring containment is architecturally enforced rather than dependent on first detecting an exploit.
Vulnerability management is one of 18 critical controls in the Center for Internet Security’s Cybersecurity Framework and typically follows four phases: identifying affected assets through continuous scanning, assessing and prioritizing by severity and business context, remediating through patches or mitigating controls, and verifying that the fix closed the gap.
Traditional patch management has followed a predictable cycle: a vendor discloses a vulnerability under a CVE identifier, releases a tested patch, and makes it available on a fixed schedule, such as Microsoft’s monthly “Patch Tuesday.” According to Zero Networks, this cycle assumed weeks or months would pass between discovery and mass exploitation. That assumption is increasingly under pressure: in July 2026, Microsoft released what it called its largest Patch Tuesday to date, with 570 fixes including three zero-day vulnerabilities — more than triple the volume seen in April.
For security teams still relying primarily on patching, Zero Networks argues this creates a forced trade-off: either deploy large batches of unvalidated updates quickly, or take more time testing priority patches while accepting elevated risk in the interim — both options come at the expense of operational continuity.
According to an IBM study, 85 percent of organizations plan to increase security spending in response to AI-driven threats. Zero Networks argues that additional budget alone provides no reliable advantage if it simply reinforces existing strategies. Instead, the company says organizations need a “containment-first” architecture that stops attacks regardless of speed or initial access vector.
Zero Networks says it offers a microsegmentation solution that can be deployed in an automated way and is designed to stop ransomware and lateral movement within networks, combined with identity segmentation, zero-trust network access, and network-level multi-factor authentication.
With AI-assisted exploit development accelerating and patch volumes rising, Zero Networks expects architectural containment to move further into focus for security strategies — as a complement to, not a replacement for, traditional patch management.
