Just replace old machines? In many production environments, that’s not a realistic option.
As a result, older operating systems, insecure protocols, and existing network connections remain part of the OT infrastructure and can become points of vulnerability.
Companies therefore need a security architecture that protects existing machines and systems without fundamentally restructuring production. Security gateways, network segmentation, firewalls, IDS/IPS, and secure remote access can provide an additional layer of protection.
Find out how existing OT environments can be secured step by step with the Endian Secure Digital Platform in our latest article.
