Integrity360 Launches Managed OT Security Services
The new portfolio provides ongoing management of security across industrial and operational technology environments.
Updated on Nov. 3, 2026 in Cybersecurity

Integrity360 has launched a new portfolio of Managed OT Security Services, extending its existing operational technology security practice. The portfolio provides ongoing management of security across industrial and operational environments.
Why it matters
The launch responds to growing demand from organisations for ongoing management of OT security. It builds on Integrity360's managed security services track record and its existing OT consulting and professional services practice.
The portfolio spans five service areas: Managed OT Security Posture, Managed OT Access Security, Managed OT Network Security, Managed OT Threat Detection, and Managed OT Resilience & Response. Pricing and service-level metrics were not disclosed in the announcement.
The players
Integrity360
Integrity360 is a cybersecurity services provider with circa 900 employees across 16 regional locations in the UK, Europe, Africa and Canada, backed by an investment from August Equity in June 2021.
Holiseum
Holiseum is a French operational technology security specialist that Integrity360 acquired in March 2025 to strengthen its OT practice.
The details
The portfolio includes compliance-ready reporting, risk-based assurance, and control mapping to support governance. Managed OT Threat Detection provides monitoring configured for OT environments to detect, validate and investigate threats, followed by escalation and response guidance. Integrity360 will also help organisations establish response playbooks defining how security operations teams collaborate with plant and OT engineering teams.

Market Landscape
Industrial operators have traditionally relied on episodic OT assessments, and managed OT security is emerging as a continuous-operations alternative to that model. Integrity360's launch places it among providers competing to offer ongoing OT monitoring and response rather than project-based consulting.
Organisations running industrial or operational technology can now contract for ongoing OT monitoring, threat detection and response rather than relying solely on periodic assessments. The services include compliance-ready reporting that can support governance obligations for operational environments.
The takeaway
Operational technology security increasingly requires continuous monitoring that bridges security operations and plant engineering teams. Organisations should assess whether their OT environments have defined response playbooks linking those groups.
