  • Publication number: 20260319914
    Abstract: A multi-agent AI-driven system addresses limitations of Large Language Models (LLMs) in automated software testing by integrating symbolic formal verification and generative AI. The system analyzes software to identify implied functions, dependencies, and static variables, generating mock-up compilation units to enable isolated unit testing. A symbolic verification engine systematically identifies backward arithmetic and logical conditions required to execute specific code paths, overcoming the inability of LLMs to reliably perform backward reasoning. LLMs then generate executable, forward-reasoned unit tests based on these formal results. Test executions produce coverage information that highlights gaps and detects errors or regressions. Reflective analysis by LLMs further generates targeted tests and suggests improvements, enhancing software robustness and test coverage. The method effectively combines formal logic with generative AI, enabling automated, reliable, and comprehensive software testing.

  • Publication number: 20260322743
    Abstract: Systems and methods for enhancing the WireGuard protocol are provided. In one implementation, a gateway device is arranged in a cloud-based system and connected via tunnels to multiple connectors in a client network. The gateway device is configured to assign loopback IP addresses to the multiple connectors and populate the loopback IP addresses into AllowedIP lists associated with the multiple connectors, the multiple AllowedIP lists addressing the connectors as crypto peers for use with the WireGuard protocol. Based on network operating parameters, the gateway device is configured to determine a packet routing plan for distributing multiple packets among the connectors. When a packet of the multiple packets is determined, according to the packet routing plan, to be routed through a connector other than a designated WireGuard peer, the gateway device further performs a step of encapsulating the packet with the corresponding loopback IP address of the connector.

  • Publication number: 20260300620
    Abstract: Systems and methods described herein are configured to inspect prompts before they are transmitted to an external Large Language Model (LLM) chatbot or Generative Pre-trained Transformer (GPT). A method, according to one implementation, includes a step of intercepting a text-based prompt sent from a client device, the text-based prompt intended to be sent to an LLM chatbot. The method also includes analyzing the text-based prompt to determine whether one or more keywords exist therein. In response to detecting that one or more keywords exist in the text-based prompt, the method further includes a step of inspecting text surrounding the one or more keywords to determine whether one or more text segments include secretive information. In response to detecting that one or more text segments include secretive information, the method prevents leakage of the one or more text segments to the LLM chatbot while sending the text-based prompt.

  • Publication number: 20260278192
    Abstract: Systems and methods are disclosed for determining floor-level workplace occupancy using network telemetry. Wi-Fi change events associated with devices are received and enriched with office configuration data mapping wireless access points to physical floors. A probabilistic spatial inference engine converts signal quality values into weighted scores, aggregates scores by floor, and determines an inferred floor and confidence value. A temporal state management module validates inferred floor changes based on the confidence value and stored device state to filter noise and confirm location transitions. Confirmed changes update real-time and historical datastores to maintain aggregated floor-level occupancy counts. A machine learning module may adaptively update access point-to-floor mappings and generate predictive occupancy forecasts based on historical data.

  • Publication number: 20260280934
    Abstract: A Zero-Trust Network Access (ZTNA)-enabled Virtual Private Network (VPN) solution combines traditional VPN tunnels with ZTNA’s application-centric controls. Rather than granting broad network access, the system enforces fine-grained policies based on identity, device posture, and contextual factors. By positioning a cloud-based overlay between end users and private applications or LAN segments, it enables continuous verification and least-privileged access for both legacy and modern workloads. Key components—such as NP gateways, NP connectors, and application connectors—create outbound-only tunnels, eliminating the need for open inbound ports. Leveraging protocol-agnostic or WireGuard-based encryption, these tunnels transport traffic securely while preventing unauthorized visibility or lateral movement. Users benefit from robust, real-time security checks, application-specific routes, and seamless scalability.
