The SFP-ENC-1G as an encrypted plug-and-play solution for security-critical IP infrastructures
The requirements for securing industrial networks are constantly increasing – especially in security-relevant applications such as video surveillance, access control or process automation. Planners and installers of security technology are increasingly faced with the challenge of implementing highly secure IP communication on often existing infrastructure without making extensive changes to existing systems or establishing complex configuration processes. This is exactly where AMG Systems comes in with the SFP-ENC-1G: an industrial encryption module in Small Form-Factor Pluggable (SFP) format that encrypts IP data traffic at full line speed and is easy to put into operation.
The SFP-ENC-1G is a plug-and-play-enabled SFP carrier with integrated IPsec encryption that can be used in any standard-compliant 100 or 1000 Mbit SFP port. This allows the module to be integrated into existing network topologies without any structural changes – whether in switches, routers, media converters or network video recorders. For installers, this means no additional hardware installation, no external power supply and no complex cabling. Since power is supplied directly via the SFP port, installation is particularly space-saving – an important advantage in control cabinets or in environments with limited space. This architecture also reduces potential sources of error in the power supply.
The SFP-ENC-1G impresses with its complete end-to-end encryption of IP traffic using 128-bit AES-GCM in accordance with the IPsec standard. Both point-to-point and multipoint communication scenarios are supported. Encryption takes place at Layer 3 in static IPsec transport mode and is designed for IPv4 traffic. A special feature is the management: to ensure maximum security, access to the configuration is only possible via a separate programming device – known as out-of-band management. The device settings cannot be changed either from the host device or via the IP network itself. This security feature offers a decisive advantage for planners: the configuration remains immune to internal network attacks or unintentional changes by third parties, which is particularly important in critical applications such as government networks or energy supply.
Another argument in favour of integrating the module into overall security solutions is its compatibility. The SFP-ENC-1G is fully MSA-compliant and can therefore be used with a wide range of 100 and 1000BASE-FX SFPs available on the market. This allows existing infrastructure to be reused in its entirety – for both copper and fibre optic cabling. For installers, this means lower material costs, shorter implementation times and no need for recertification of the network structure. The module can also be used without hesitation in harsh industrial environments: the operating temperature range is -20 to +85 °C, the aluminium housing offers IP20 protection and passive cooling ensures reliable, silent operation.
The SFP-ENC-1G is particularly interesting for planners of security systems where existing systems need to be retrofitted or new systems need to be upgraded to a high level of security with minimal effort – for example, in video technology, IP-based access control systems or when networking control components via insecure network segments. Implementing the module allows sensitive data to be transmitted in encrypted form without having to replace existing network devices such as switches or cameras.
Technical planning is further simplified by the clear separation of device and configuration: individual devices can be preconfigured at the factory or set up on site using a separate USB programming device. For larger projects, preconfigured modules are also available in pairs, which further reduces the effort required for commissioning.
The SFP-ENC-1G provides planners and installers with a lean, highly secure and reliable solution for securing industrial IP networks – without compromising on performance, compatibility or flexibility. At a time when cybersecurity is becoming increasingly important in physical security technology, this module is an effective building block for comprehensive security architectures.
