This is a managed service from Sectra Communications for logging, storing, and analyzing network traffic and activity data from critical IT and OT systems, including industrial control systems (SCADA/PLC). The service is designed to help organizations that operate industrial networks detect unwanted or malicious activity on critical servers and infrastructure. Sectra installs monitoring capabilities within the customer's OT/IT environment and forwards collected traffic and log data to Sectra's Security Operation Center (SOC), where analysts review it around the clock. Key data sources recommended for logging include historians, workstations/PCs, SCADA systems with PLCs, HMIs, remote access solutions, firewalls, and Active Directory servers. The goal of collecting and analyzing this data is to reduce detection time for incidents, support evidence preservation after security events, and provide information needed to restore systems to normal operation following an incident. In addition to the logging and analysis service, Sectra offers a risk and security analysis service where its security experts review a customer's production environment to identify, prioritize, and address risks affecting operational uptime. This results in a report and action plan intended to guide security investment decisions while balancing operational efficiency with security requirements. The service is aimed primarily at operators of critical infrastructure and industrial environments, such as energy companies, seeking to maintain production continuity and improve resilience against cyber threats targeting OT networks.</description> <parameter name="summary">Managed logging, monitoring and SOC analysis service for critical IT/OT and SCADA networks

MBsecure+ is a hardware gateway that provides physical isolation between industrial control system (PLC) networks and HMI application servers. It acts as a hardware bridge between two Linux units, acquiring PLC data over TCP/IP and relaying it to the HMI without establishing a physical link between the PLC and HMI network. Isolation occurs at OSI Layer 1&2 without relying on CPU, software, or IP addressing, preventing direct network access to the PLC from the HMI side. The device supports multiple SCADA/ICS communication protocols used across industries such as energy, water, oil and gas, automotive, transportation, and petrochemicals, including Modbus RTU, Syslog, MQTT, and SMTP, with OPC DA/UA, DNP3, and BACnet planned for future releases. It supports up to 247 Modbus devices per unit and multiple HMI units, with configurable access restrictions via an HMI list. Access to the unit itself is secured through HTTPS with encryption keys. The hardware includes dual RJ-45 CAT6 ports, no fans or disk drives, DIN rail mounting, and supports high availability through unit redundancy. Core use case: interconnecting network segments with different security classifications (e.g., PLC/OT network and HMI/IT network) while eliminating the ability for devices on the HMI network to directly access or hack the PLC.</description> <parameter name="summary">Hardware gateway isolating PLCs from HMI networks while relaying SCADA/ICS protocol data
