What We Build

Everything we make serves one purpose: see what's on the network, at any scale.

ExaViewer

Packet analysis with web UI, terminal TUI, and CLI. See problems, not just packets.

ExaCapture

High-speed packet capture infrastructure with analysis tokens and security enforcement.

ExaVolume

FUSE virtual filesystem. Projects petabytes of packet data as navigable directories and files.

jNetWorks SDK

800 Gbps capture engine with DPDK and Napatech. The foundation under every Exa* product.

jNetPcap SDK

Java libpcap wrapper. 17+ years, 1M+ installs. Cross-platform. Open source.

Bonafide

Open security specification. Quantized encryption, passwordless authentication, zero-trust enforcement.

Community First

Both jNetPcap and jNetWorks core modules are open source under Apache 2.0 and published on Maven Central. The high-performance backends (DPDK and Napatech SmartNIC) are commercial add-ons available through our product portal.
