Following attacks on water systems across seven U.S. states in August 2026, research indicates that most infrastructure organizations lack continuous monitoring for building automation and IoT assets. A Honeywell Technologies survey of 603 leaders highlights significant gaps in asset management and incident readiness.
Why it matters
The persistent inability to monitor legacy infrastructure systems creates security vulnerabilities that directly impact recovery times during active incidents. This gap remains a challenge as older controllers often lack the fundamental authentication or encryption capabilities required to defend against modern threats.
Only 21% of surveyed organizations maintain a complete asset inventory, while just 16% and 20% utilize continuous monitoring for building automation systems and IoT devices, respectively. These monitoring gaps coincide with an average downtime of 16.2 hours for significant security incidents.
The players
Honeywell Technologies
An industrial conglomerate specializing in building automation, control systems, and security software for critical infrastructure.
The details
Asset inventory involves cataloging every device connected to an organizational network to maintain a map of potential entry points. Continuous monitoring functions by tracking device traffic and behavior in real-time, allowing security teams to flag anomalies. Many facilities struggle to implement these measures due to aging legacy equipment that predates modern security standards like built-in encryption or authentication protocols.
Timeline
May 2026 – June 2026: Honeywell Technologies conducted the survey of industry leaders.
August 2026: Attackers targeted water systems across seven U.S. states.
The Tech Race
The findings underscore a deepening disconnect between regulatory compliance and actual operational resilience, with 74% of organizations that passed all audits still reporting significant security incidents. This trend suggests that current compliance benchmarks are failing to account for the unique risks posed by unmonitored legacy IoT and building automation systems.
Organizations with mature asset management capabilities recover from security incidents at a significantly faster rate than those relying on manual or sporadic tracking. Industry leaders must prioritize the integration of continuous monitoring to shrink the current 16.2-hour average downtime experienced by affected firms.
The takeaway
The data reveals that mere compliance is not a proxy for safety in critical infrastructure, as most audited firms remain highly susceptible to significant downtime. Future security investments should focus on closing the visibility gap through automated, real-time inventory and monitoring tools.
