SAM OPUS is a network security platform delivered as a service (Security as a Service), designed for Managed Service Providers (MSPs) to deploy to their small business customers. It operates as a software agent installed on Linux-based routers — either pre-integrated on customer-premises equipment (CPE) before shipment or deployed over-the-air as a firmware update — removing the need for on-site configuration or maintenance. The platform provides multi-layered network security covering three primary domains: - **Network Security:** Protection against hijacking, intrusion, malware, and other online threats across the entire business network. - **Web Security:** Filtering of inbound and outbound web traffic to block malicious sites and phishing attempts. - **IoT Security:** Zero-trust device access enforcement, ensuring only verified devices connect to the network, with behavioral anomaly tracking and virtual patching for discovered vulnerabilities. MSPs manage customer environments through a centralized management workspace, also accessible via API. The platform supports two deployment modes: installation on an existing router or use of a SAM-provided router. Feature activation can be performed instantly and remotely after customer sign-up. SAM OPUS is platform-agnostic, compatible with any Linux-based router, and is positioned as a scalable solution for MSPs, ISPs, and CPE vendors looking to bundle cybersecurity with connectivity offerings for small businesses.
