Qingteng Lingyu is a microsegmentation platform designed to control east-west traffic within hybrid data center environments, including public cloud, private cloud, hybrid cloud, physical machines, virtual machines, and containers. The platform consists of three components: an Agent that collects network connection and asset information in real time and manages the host firewall, a computing engine that aggregates and visualizes network connections and generates policies based on business traffic, and a console for centralized policy management and isolation operations. The platform automatically learns business access relationships and displays them through visual topology maps, supporting interactive policy creation directly on the topology. It supports policy management at various granularities, including business groups, tags, ports, and IP addresses, and can adapt policies automatically as business or environment conditions change. It includes a policy validation function that monitors and verifies policy accuracy and coverage without actually blocking traffic. In the event of a real security incident, the platform can quickly isolate compromised hosts to block lateral movement across the network. A single agent integrates microsegmentation, host security, and container security capabilities, enabling unified cross-platform security management.</description> <parameter name="summary">Microsegmentation platform for visualizing and controlling east-west traffic to stop lateral movement

Autek provides cross-domain security solutions for organizations that need to transfer information between networks with different security classifications or under different administrative authorities. The site describes network segmentation concepts and the devices used to enforce strong isolation between security domains, positioning data diodes and secure application gateways (guards) as alternatives to conventional firewalls when full protocol-stack separation is required. Two categories of cross-domain devices are covered: - Unidirectional devices (data diodes), which allow information transfer in only one direction. These can be hardware-based, where a physical mechanical component guarantees one-way transmission, or software-based, where virtual machines or microkernels enforce unidirectionality. - Bidirectional devices (application gateways), which allow secure two-way information transfer between separated security domains. These gateways perform data flow filtering ("guard" functionality), including format and content control, and can require digital signature authorization of data before it crosses domains. The content explains that standard firewalls are sufficient only when networks are not physically separated and routing between them is permitted. For cross-domain interconnections between differently classified networks or authorities, higher-assurance devices such as guards or data diodes are needed because they prevent packet/connection routing and break the protocol stack completely.</description> <parameter name="summary">Cross-domain security devices (data diodes and secure gateways) for segmenting networks
