We have a Network Extension system extension implementing NEFilterPacketProvider to inspect all incoming and outgoing network traffic. We also want to monitor socket-level events such as connect(), bind(), and similar, by leveraging the Endpoint Security framework. Does this require developing a separate system extension for Endpoint Security? Additionally, what is the recommended approach for sharing context and data between the Network Extension and the Endpoint Security extensions?

Our application currently uses NEFilterPacketProvider to filter network traffic based on Layer 4 rules (5-tuple: source IP, destination IP, source port, destination port, and protocol) on a packet-by-packet basis. We now want to extend this filtering to also consider the associated process—for example, allowing traffic from a specific source IP to a destination IP and port only if it's associated with a specific local process. That is, we’d like to make filtering decisions not just based on the 5-tuple, but also on the identity of the process either sending or receiving the traffic. We’ve looked into NEFilterSocketProvider, which does expose Layer 7 information such as process identifiers. However, it doesn’t seem to be tightly synchronized with the packet flow handled by NEFilterPacketProvider. As a result, there’s a risk that we might only get process information after the TCP handshake is complete, or before the socket is fully bound—at which point some of the 5-tuple fields (such as the local port) may still be unavailable. What we need is a way to correlate the 5-tuple with the relevant process name (either sender or receiver) at the time the first packet—e.g., a SYN packet—is about to be sent or received. Is there a recommended way to achieve this kind of early, process-aware filtering using NetworkExtension APIs?

Hello, We have a SwiftUI-based application that runs as a LaunchAgent and communicates with other internal components using Unix domain sockets (UDS). On Sequoia (macOS virtualized environment), when installing the app, we encounter the Local Network Privacy Alert, asking: "Allow [AppName] to find and connect to devices on the local network?" We are not using any actual network communication — only interprocess communication via UDS. Is there a way to prevent this system prompt, either through MDM configuration or by adjusting our socket-related implementation? Here's a brief look at our Swift/NIO usage: class ClientHandler: ChannelInboundHandler { ... public func channelRead(context: ChannelHandlerContext, data: NIOAny) { ... } ... } // init bootstrap. var bootstrap: ClientBootstrap { return ClientBootstrap(group: group) // Also tried to remove the .so_reuseaddr, the prompt was still there. .channelOption(ChannelOptions.socketOption(.so_reuseaddr), value: 1) .channelInitializer { channel in // Add ChannelInboundHandler reader. channel.pipeline.addHandler(ClientHandler()) } } // connect to the UDS. self.bootstrap.connect(unixDomainSocketPath: self.path).whenSuccess { (channel) in .. self.channel = channel } ... ... // Send some data. self.channel?.writeAndFlush(buffer).wait() Any guidance would be greatly appreciated.

We have network system extension which is fundamental part of our application and needs to be installed before the application can run. In many cases we need the installation to be automated, i.e. without logged-in user (with the help of MDM solution like JAMF). Is there a way to activate the extension fully automated without logged-in users? I tried to call 'open -W -a /Application/' from the package's post install script. But seems launch fails if no user is logged in.
