BLOKWORX SCUD + CDR (Secure Cloud Unified Defense + Cloud Detection and Response) is a cloud-native email and collaboration security platform designed for cloud-based environments. Unlike traditional MX record-based email filtering solutions, SCUD + CDR connects directly to cloud platforms via API — without acting as a proxy — making it invisible to external reconnaissance. This architecture allows it to operate alongside existing native security controls rather than replacing or disabling them. The platform scans for both internal and external threats, including inbound, outbound, and internal email threats, as well as compromised account activity and login anomalies. It is capable of detecting threats historically present in the environment, not just new ones. Beyond email, SCUD + CDR extends coverage to file-sharing, collaboration, and messaging platforms, protecting against impersonation, malicious files, data breaches, and phishing attacks across those channels. Security functions the platform displaces include: - MX record email filtering - SaaS file monitoring - Email encryption - Anti-phishing - SaaS account login monitoring - SIEM for email and account activity - SOAR for email and account activity - Business email compromise (BEC) prevention - Anti-spam - Manual Office 365 DLP controls Deployment is described as app-based with minimal configuration. The platform is offered as a managed service through BLOKWORX and is positioned for managed service providers (MSPs) as a resellable security layer.
