History

Enea was founded 1968 by Rune Engman as Engmans Elektronik AB. Their first product was an operating system for a defence computer used by the Swedish Air Force. During the 1970s the firm developed compiler technology for the Simula programming language.

During the early days of the European Internet-like connections, Enea employee Björn Eriksen connected Sweden to EUnet using UUCP, and registered enea as the first Swedish domain in April 1983. The domain was later converted to the internet domain enea.se when the network was switched over to TCP and the Swedish top domain .se was created in 1986.23

Products

Network data layer

Stratum is Enea's network data layer platform designed for 4G and 5G mobile networks. It enables mobile operators to manage subscriber and session data through a virtualized data schema that unifies data models across network generations. Developed according to 3GPP standards, Stratum allows interoperability between 4G systems and the 5G Core, supporting use cases such as edge computing and network slicing. The platform is cloud-native and designed to reduce reliance on proprietary infrastructure by enabling distributed data management.4

Voice Firewall

Enea Voice Firewall is a network security product developed by Enea to detect and block fraudulent voice calls, including those using caller ID spoofing. It operates on a zero-trust model, analyzing traffic in real time to prevent scam and robocalls from reaching subscribers. In 2023, Telecom Egypt reported a significant reduction in fraudulent calls after deploying the solution.5

OSE

The ENEA OSE real-time operating system first released in 1985.6

The Enea multi core family of real-time operating systems was first released in 2009.7

The Enea Operating System Embedded (OSE) is a family of real-time, microkernel, embedded operating system created by Bengt Eliasson for ENEA AB, which at the time was collaborating with Ericsson to develop a multi-core system using Assembly, C, and C++. Enea OSE Multicore Edition is based on the same microkernel architecture. The kernel design that combines the advantages of both traditional asymmetric multiprocessing (AMP) and symmetric multiprocessing (SMP). Enea OSE Multicore Edition offers both AMP and SMP processing in a hybrid architecture. OSE supports many processors, mainly 32-bit. These include the ColdFire, ARM, PowerPC, and MIPS based system on a chip (SoC) devices.

The Enea OSE family features three OSs: OSE (also named OSE Delta) for processors by ARM, PowerPC, and MIPS, OSEck for various DSP's, and OSE Epsilon for minimal devices, written in pure assembly (ARM, ColdFire, C166, M16C, 8051). OSE is a closed-source proprietarily licensed software released on 20 March 2018. OSE uses events (or signals) in the form of messages passed to and from processes in the system. Messages are stored in a queue attached to each process. A link handler mechanism allows signals to be passed between processes on separate machines, over a variety of transports. The OSE signalling mechanism formed the basis of an open-source inter-process kernel design project named LINX.8

Linux

Enea Linux provides an open, cross-development tool chain and runtime environment based on the Yocto Project embedded Linux configuration system.

Hypervisor

Enea Hypervisor9 is also based on OSE microkernel technology and runs Enea OSE applications and takes as guests Linux Operating System and optionally semiconductor specific executive environments for bare-metal speed packet processing[better source needed]

Optima

Enea Optima development tool suite for developing, debugging, and profiling embedded systems software10[better source needed]

The Element

The Element middleware software for high-availability systems, based on technology developed by Equipe Communications Corp11
