ifAsec GmbH is a German security software manufacturer for managed access control in corporate networks. In cooperation with the Fraunhofer Gesellschaft, we are researching new approaches on Risk and Compliance Management. With our Security Appliance SCUDOS ® and our service portfolio we offer the highest protection against threats and cyber-attacks. With the rise of trends like BYOD and IoT, attacks are creating even more serious damages within increasingly opaque LAN networks - keyword: advanced persistent threats. Especially in the entrepreneurial SMB there is much room for improvement, as networks are often insufficiently hedged. Without knowing which devices are connected to a network and what services they provide, no effective protection can be enforced. "Only those who know their network can effectively protect it!.SCUDOS ® counteracts internal attacks by shifting from the traditional perimeter-based security concept towards a zero-trust model.
