researched Aug 2026RADICL provides managed cybersecurity and regulatory compliance services to high-risk and regulated organizations, including defense industrial base and other regulated industries. Its offering is packaged as a single fully-managed cybersecurity-as-a-service subscription in which RADICL acts as the customer's security operations team and compliance partner, combining an autonomous virtual security operations center (vSOC) built on the proprietary RADICL Platform with AI-driven workflows and human security and compliance experts.
The service line comprises five named modules: Managed Compliance Adherence (MCA) for CMMC and NIST 800-171 readiness, guided self-assessments, gap closure, audit trail and evidence capture, and external audit preparation; Managed Log Analytics (MLA), covering log collection, normalization, retention and searchable investigation, with 14- or 90-day velocity search plus a one-year archive, AI-assisted natural language search, and on-demand compliance evidence export; Managed Detection & Response (MDR), split into endpoint, identity and network coverage with 24/7 monitoring, incident response and virtual CISO support; Managed Attack Surface (MAS) for continuous vulnerability scanning, prioritization and tracked remediation; and Managed Security Awareness (MSA) for annual and ongoing training plus phishing simulations.
