In the digital era, one could argue that legacy systems are extremely vulnerable for cyber threats. After all, these systems are often not equipped for the challenge that lies ahead. For instance, updates for older systems are running out, which makes it difficult to maintain the right cyber security level. More-over, the digital transformation leads to hybrid-systems: on-premise (legacy) systems are connected to private and public cloud, which makes them more vulnerable for cybercrime.
At Thales we believe that, however situations like these are inevitable, there are indeed opportunities to protect older technology and solutions that incorporate older technology, in an effective way. We have experience in developing intrusion detection systems to protect legacy systems against hacking attempts.
