The SME sector is booming, but many companies are facing an acute shortage of specialists, particularly in IT, even in the face of greater and greater IT risks. IT networks especially are set to experience rapid growth in the coming years. With an increasing number of endpoints, the Internet of Things, digitization and the networking of communication and production applications, even the IT infrastructures of “smaller” companies are becoming more and more complex and unclear. More than ever, companies need the best possible scalable security to provide effective protection for their IT networks. At present, however, small and medium-size enterprises (SMEs) shy away from proactively addressing their network security needs because the process seems complicated and expensive. As a result, it is often difficult for IT system vendors to sell their seemingly complex NAC solutions.
