NetCrypt S20

ST Electronics (Info-Security) Pte Ltd.


Compact & High Performance IP Encryptor

NetCrypt S20 is a compact IP encryptor that enables the user to leverage on public Ethernet/IP infrastructure to connect to multiple sites in a secure manner. NetCrypt S20 employs AES algorithm for data confidentiality, Secure Hash Algorithm (SHA) for integrity protection as well as internet key exchange (IKE) protocol for keys derivations and authentications. The built-in Firewall performs packet filtering and supports NAT/PAT features.

Supporting up to 50 tunnels with a maximum encrypted throughput of 100Mbps, NetCrypt S20 packs a big punch in a small foot print. It is ideal for deployments as a security gateway in a small office corporate LANs, site-to-site VPN, mobile vehicle and site-to-site wireless inter-offices connectivity.

NetCrypt S20 is interoperable with NetCrypt series of IP encryptor, allowing user to form a secure VPN between the corporate HQ and remote sites/branch offices. With the flexibility to use industry standard Simple Network Management Protocol (SNMP) network management system, NetCrypt S20 allows local and remote monitoring of devices, and firmware field-upgrading to ease new features introduction, algorithm updates and maintenance.
