About us

The people behind Qato.

The Qato team is led by practitioners with deep experience in federal cybersecurity, threat detection, and operational resilience. Our leadership and engineers have supported missions across defense, civilian, and critical-infrastructure environments — giving us firsthand insight into how cyber anomalies emerge, evolve, and evade traditional monitoring tools. Our development team blends hands-on cyber operations expertise with software engineering, AI integration, data analysis, and security automation. The result is an anomaly-detection engine that catches subtle, low-and-slow threats, strengthens program integrity, and delivers transparent, defensible insights security teams can trust.

    John Fleming

    Senior Advisor

    Mr. John Finbarr Fleming is a former CIA Senior Intelligence Service (SIS) officer with a long record of success in the intelligence business and, since retirement from the government, in the private sector. He retired from the CIA as Assistant Director of CIA for Korea, after a 31-year career, and was awarded the Distinguished Career Intelligence Medal for his service.  In government, he managed complex, multi-million-dollar programs in fast paced, conflict-zone environments overseas and in CIA Headquarters over the course of a career spent largely in the Middle East. Mr. Fleming served as Chief of Station in a War Zone, leading and protecting his large team of intelligence professionals from across the Intelligence Community and Military. His experience, however, extends beyond managing in conflict zones to substantive de-escalatory work on conflict resolution in both the Israeli Palestinian Issue and with the U.S. Government’s efforts to negotiate with North Korea.  Since leaving the government in 2020, Mr. Fleming has carried these skill sets into a flourishing private sector career.  Mr. Fleming led the Federal Sector sales team for Owl Cyber Defense, before transferring to Acuity International, where was a Senior Vice President for Business Development. Mr. Fleming then became Executive Chairman of Paragon U.S., leading the offensive cyber company to a successful acquisition by AE Industrial Partners.  Mr. Fleming speaks Arabic language, having completed two years of language training at the Foreign Service Institute in Tunisia. In addition to degrees in International Relations and English from Lehigh University, Mr. Fleming obtained an MS in National Security Studies from the National War College.
