      - IPsec tools
        The QNX Neutrino Core Networking uses the IPsec tools from the NetBSD source base and incorporates it into its source base.
      - Hardware-accelerated crypto
        The io-pkt-v4-hc and io-pkt-v6-hc managers have the (hardware-independent) infrastructure to load a (hardware-dependent) driver to take advantage of dedicated hardware that can perform cryptographic operations at high speed. This not only speeds up the crypto operations (such as those used by IPsec), but also reduces the CPU load.

  - Customizing a BSP
    While QNX provides Board Support Packages (BSPs) for many common platforms and their individual variants, in some cases, you need a BSP for a board that QNX does not provide. If this is the case, you can modify a QNX BSP or develop your own.
