Beyond throughput: The critical last mile of SecOps

As an industry, we’ve largely figured out how to solve for the early stages of incident handling, from alert triage to enrichment, correlation, initial investigation, and overall noise reduction. A combination of SIEM, SOAR, managed services, and agentic AI pipelines can clear 90% of baseline operational noise. But throughput is not a successful defensive outcome.

No matter how efficiently we handle the first 90% of the work, the final 10% remains. These residual, high-stakes cases are defined by ambiguity: an alert that falls outside established playbooks, lateral movement disguised as administrative behavior, or the high-risk decision to isolate a production system with incomplete data.

Welcome to the critical last mile of security operations.

This reality drives investment. Enterprises have always balanced internal and external resources for early-stage triage, and are increasingly willing to pay a premium for incident resolution. Look at market behavior: the shift from legacy, triage-focused MSSPs to Managed Detection and Response (MDR) proves this point. Whether by building, buying, or partnering, organizations don’t pay a premium to cut 10,000 alerts down to 1,000; they pay to turn those 1,000 investigative leads into the 10 threats that require an informed, proportional, and swift response. Budgets always have been and will continue to be directed toward the specialized teams and processes required to manage this delta.

Security posture is ultimately defined by how an organization executes at this edge. When the limits of automation and technical controls are exceeded, defensive success depends entirely on operational capability: platform understanding, business context, experience, decisiveness, and clear communication under pressure.

As we adopt new technologies and ways of working, our core mandate hasn’t changed. We should lean aggressively into AI and agentic solutions to solve the problem of scale, as this is how we clear the field. But we cannot confuse throughput with effectiveness. Embrace the technology to get to the edge faster, but ensure we have the specialized expertise and operational capacity to execute the critical last mile, where the fight is won.
