Tor network intelligence

Intercept at
the kernel

eBPF probes on Tor exit nodes. Proprietary ensemble architecture. Sub-millisecond attribution. We see data exfiltration as it happens — not days later.

The problem

Stolen data travels through Tor.

Every dark web monitoring tool scrapes forums after the breach. They find your data 204 days later, posted for sale.

We sit at the exit relay kernel and intercept exfiltration as it happens. 10,482 sensors. Global coverage.

Kernel-level ingestion

XDP programs attach directly to NIC drivers at the data link layer. Zero-copy AF_XDP ring buffers shuttle raw frames to userspace without a single memcpy. 10Gbps sustained, zero drops.

SEC("xdp")
int ns_capture(struct xdp_md *ctx) {
    void *data     = (void *)(long)ctx->data;
    void *data_end = (void *)(long)ctx->data_end;

    struct flow_key key;
    if (extract_flow(&key, data, data_end) < 0)
        return XDP_PASS;

    bpf_ringbuf_output(&rb, &key, sizeof(key), 0);
    return XDP_PASS;
}

“NodeSight gave us a 72-hour lead on a credential exfiltration before our internal systems flagged anything. We've never had this kind of visibility into Tor traffic.”
