Revenue model

1. Managed SOC-as-a-Service: Primary revenue stream. Subscription-based 24/7/365 managed SOC services delivered from a UK-based SOC staffed by SC-cleared analysts. Covers threat detection and response, OT security monitoring, dark web monitoring, incident response, and cyber assessment/consultancy. Two platform tiers: Cumulo Standard OT (OT-focused) and Cumulo Enterprise (unified IT/OT). Pricing is transparent and quote-based.
2. Cyber Assessment & Consultancy Services: Project-based professional services revenue covering Microsoft 365 Security Reviews, Microsoft Sentinel Operations Assessments, CAF Assessments, Tabletop Incident Exercises, Ransomware Readiness Exercises, and Dark Web Threat Assessments / Reports. Used as a land-and-expand motion into the managed SOC subscription.
3. Partner-Co-Delivered Compliance & SOC Bundles: Joint service offerings with strategic partners (e.g., A&O Corsaire) that combine SOC monitoring with compliance assurance for CNI/defence/regulated buyers, packaged as a single audit trail from assessment through to live monitoring.

Core offering

e2e-assure operates a UK-based 24/7/365 Security Operations Centre delivering managed threat detection and response across IT and OT environments, powered by its proprietary Cumulo AI SOC platform. The company combines SC-cleared analyst coverage, passive OT protocol monitoring, digital twin attack simulation, and integrated Microsoft Teams-based collaboration to serve UK critical national infrastructure, defence supply chain, manufacturing and government buyers under onshore data residency.

Product overview

e2e-assure delivers its offering as a platform-plus-modules architecture built around Cumulo, its sovereign AI-driven SOC platform. Cumulo is offered in tiers: Cumulo Enterprise (unified IT/OT detection) and Cumulo Standard OT (OT-focused starting tier), both delivered from a UK-based SOC staffed by SC-cleared analysts. Surrounding the platform are managed service modules including Threat Detection and Response (with sub-modules such as Modern Workplace Protection, Endpoint Detection & Response, Cloud Threat Detection & Response, Network Threat Detection & Response, and Security Log Analytics), OT Security Monitoring, Dark Web Monitoring, and Incident Response, plus a Cyber Assessment Services consultancy covering Microsoft 365 Security Review, Microsoft Sentinel Operations Assessment, CAF Assessment, Tabletop Incident Exercise, Ransomware Readiness Exercise, and Dark Web Threat Assessment. The Microsoft Teams SOC Channel App is a native add-on that brings the SOC into Microsoft Teams, and the on-site OT Telemetry Analyser extends the platform into industrial sites. All telemetry, case data, and encryption keys remain within UK borders, and the platform is designed to support NCSC CAF, NIS2, IEC 62443, and the MOD Cyber Security Model evidence requirements.

Direct peers

• Bridewell: UK-based cybersecurity consultancy and MSSP providing managed detection and response across IT and OT for CNI, financial services and government. Directly comparable in size, geography, customer segments and sovereign delivery model.
• Dragos: US-headquartered OT cybersecurity specialist providing asset discovery, threat detection and incident response for industrial environments. Closest product peer for e2e-assure's Cumulo OT capability, though lacks e2e-assure's UK sovereign delivery and unified IT/OT SOC.
• Claroty: OT security vendor (also referenced in e2e-assure team background) specialising in extended IoT/OT visibility and threat detection for industrial, healthcare and commercial environments. Comparable on OT monitoring technology though delivered as a product rather than managed service.
• eSentire: Global managed detection and response provider with explicit IT/OT/IoT coverage and 24/7 SOC operations. Comparable in managed-services model and OT extension though lacks UK sovereignty positioning.

Broad incumbents

• NCC Group: UK-listed cybersecurity services and software firm with a significant managed detection, incident response and OT/industrial cyber practice serving CNI, defence and regulated industries. Larger, broader portfolio but overlaps heavily on e2e-assure's target segments.
• BAE Systems Applied Intelligence: UK-headquartered defence and cyber services business delivering managed security, threat intelligence and sovereign cyber operations to government, defence and critical infrastructure customers. Direct competitor for the same SC-cleared, UK-sovereign contracts.
• Darktrace: UK-founded AI cybersecurity company offering self-learning threat detection and autonomous response across IT and OT (Darktrace OT). Comparable on UK origin, AI-driven detection and OT capability, but product-led rather than managed-service-led.
• Mandiant (Google Cloud): Global cyber threat intelligence, incident response and managed detection provider now part of Google Cloud. Comparable on incident response, SOC advisory and CNI/defence-grade cyber services though operates at significantly larger scale.

Emerging players

• Forescout: Cybersecurity vendor specialising in OT, IoT and connected device visibility and security, serving CNI, manufacturing and defence-aligned buyers. Comparable on OT asset discovery and protocol coverage though positioned as a platform rather than SOC service.
• Nozomi Networks: OT and IoT security specialist providing network visibility, anomaly detection and asset intelligence for industrial environments. Comparable on OT protocol support and industrial customer base.
