At the Milken Conference in May 2026, Robert F. Smith, founder and CEO of Vista Equity Partners, described a shift that every security leader should hear. Software, he said, has moved through three states: product, then service and now worker. “That agent, that software, actually does work.” Companies that do not make the transition to software as a worker, he was blunt, risk being disintermediated entirely. He is not only right because organizations risk falling behind the competition as Al increases efficiency, but also because agentic systems have the potential to address systemic challenges many organizations are facing today.

Why Cybersecurity Needs Agents Now

Security teams are being asked to do more, with less, in environments that are harder to see. Four problems persist in cybersecurity, and Al agents have the capability to address some of these issues.

• The workforce shortage cannot be solved by hiring. ISC2 estimates a global shortfall of 4.8 million cybersecurity professionals. An agent that triages alerts, correlates telemetry and drafts incident summaries does not replace those people, but it increases efficiency.
• The defensive asymmetry is structural. Attackers probe at machine speed. Defenders monitor millions of events manually and respond in hours or days. An agent that detects, correlates and contains at machine speed changes that.
• Limited budgets force most security teams to choose between capabilities. An agent working across multiple domains in parallel changes what a small team can cover.
• System complexity has grown beyond what manual processes can govern. A modern enterprise runs thousands of endpoints, dozens of cloud services, hundreds of SaaS applications and an expanding mesh of APIs. An agent can monitor across that surface simultaneously.

For decades, the security equation has favored attackers. Attackers need to succeed once. Defenders need to succeed every time. Attackers don’t need to move fast, they just need to get it…
