Cybersecurity staff burnout in OT: what should teams change first?

TL;DR: OT security teams are being pushed into burnout by daily threat churn, a widening IT/OT attack surface, and limited visibility into what matters most, with 37% of cybersecurity professionals saying they cannot handle the current workload, according to Nozomi Networks. The real issue is governance depth, not just headcount, because reactive control programs collapse when prioritisation, training, and visibility are all under strain.

Editorial analysis by NHI Mgmt Group, based on content published by Nozomi Networks: “An ICS Cybersecurity Storm is Brewing: How to Prevent Staff Burnout”.

By the numbers:

• 37% of cybersecurity professionals felt they were unable to handle the current workload, according to Cyber Security in 2019 research cited by Nozomi Networks.
• Two-thirds considered quitting their jobs due to the pressure of cyber threats, according to Cyber Security in 2019 research cited by Nozomi Networks.
• Security technology evaluation and procurement cycles can take 12 to 24 months in OT environments, according to Nozomi Networks.

Key questions

Q: What breaks when OT security teams are forced to operate in permanent reactive mode?

A: Reactive OT security breaks when every decision becomes an exception, because staff stop having the time and context needed to prioritise real exposure.

Q: Why does IT/OT convergence make cybersecurity workload harder to sustain?

A: IT/OT convergence widens the number of systems, users, and access paths that must be governed, but responsibility is often split across teams with different priorities.

Q: What are the signs that OT security governance is becoming overloaded?

A: Common signs include recurring manual exceptions, delayed offboarding, patch backlogs that never shrink, and security work that is always dominated by the latest incident or alert.

Practitioner guidance

• Define OT access ownership by role and system Assign explicit accountability for granting, reviewing, and removing access across OT engineers, SOC staff, contractors, and service accounts.
• Replace ad hoc patching with risk-ranked remediation Use asset criticality, exposure context, and operational dependency to decide what gets fixed first.
• Build workload relief into detection and triage Automate routine visibility and alert correlation so staff can spend time on higher-value decisions instead of repetitive review.

Bottom line: OT burnout is not just a staffing issue, because overloaded teams cannot sustain the governance, monitoring, and response cadence that industrial environments demand.
