Products and Services
- Cyber Operations Risk & Response™ Platform: Critical Start’s cloud-native platform that unifies alert visibility, response workflows, risk context, reporting, and service telemetry across connected security tools. It supports asset criticality, response orchestration, health monitoring, and a consolidated view of threats and mitigations.
- Managed Detection & Response (MDR): Critical Start’s flagship managed service for 24x7x365 threat monitoring, investigation, and response across endpoint, email, identity, cloud, network, and OT environments. It is designed to reduce blind spots, validate signal coverage, and accelerate containment with human-driven analysis.

The offering includes breach scoping, investigation, containment, eradication, recovery support, IR retainers, and digital forensics for sensitive investigations.
- Managed Vulnerability Management: A managed service for continuous vulnerability scanning oversight, analysis, remediation guidance, and workflow coordination. It combines scanner output with threat intelligence and operational support to improve prioritization and patch execution.
- Vulnerability Prioritization: A risk-based capability that enriches vulnerability data with exploit intelligence, asset criticality, and business context so teams can focus remediation on the issues most likely to matter first. It can be used standalone or alongside Managed Vulnerability Management.

- Cyber Threat Intelligence (CTI): Threat intelligence services that monitor emerging threats, vulnerabilities, malware activity, and attacker behavior to inform detections and response. CTI outputs are used to provide customers with timely, actionable intelligence and security guidance.
- Managed XDR: A managed extended detection and response offering that expands visibility across user, cloud, application, and network telemetry without requiring customers to own or operate a third-party SIEM. It is built to increase detection coverage and simplify log source onboarding.
- Managed SIEM: A managed service for customers using platforms such as Microsoft Sentinel, Splunk, and Sumo Logic. It adds configuration support, health monitoring, log source optimization, threat monitoring, and risk reduction reviews to improve SIEM performance and value.
- Critical Start Cyber Risk Register: A risk management offering that centralizes cyber risk identification, tracking, and governance with dashboards, workflows, and audit trails. It is aimed at improving visibility, accountability, and operational follow-through on cyber risk decisions.

- Cyber Research Unit (CRU): Critical Start’s research function focused on threat research, intelligence production, and detection development. It helps enrich MDR outcomes with ongoing analysis of exploited vulnerabilities, malware, attacker techniques, and evolving risk trends.
Target Customers
Critical Start serves organizations that need continuous security operations outcomes without building a large in-house SOC. Its offerings fit security teams that already use multiple tools and want stronger monitoring, clearer response ownership, and more measurable value from existing endpoint, SIEM, XDR, cloud, and vulnerability investments.
The company appears especially relevant for midmarket and enterprise customers operating in regulated, distributed, or operationally sensitive environments. Its customer and solution focus spans industries such as financial services, healthcare, manufacturing, retail, education, energy, and state and local government, including organizations managing both IT and OT risk.
