Organizations face the constant challenge of adopting new security strategies, such as the Zero Trust model, which operates under the premise of "never trust, always verify." This change is crucial especially in cloud environments, where identity and resource access management is more complex. In particular, the Secure Web Gateway (SWG) is a key system, which focuses on controlling user access to the web, protecting against web-based threats, and enforcing security policies. It acts as an intermediary between users and the internet, filtering and inspecting web traffic to ensure it meets the organization's security requirements.

However, implementing and managing SWGs presents significant challenges, such as integration with existing infrastructures, managing complexity, and scalability. These challenges require meticulous attention to ensure effective and efficient protection in the changing cybersecurity landscape. This article explores the purpose and function of SWGs, as well as their architecture, their ability to protect against cyber threats, and best practices for their implementation.

There are currently many standards and regulations in the industrial sector. A wide variety of them allow industrial organizations to check their level of maturity, such as IEC 62443, or to improve the security level of the organization through the application of a series of guidelines, good practices or guides, as in the case of the NIST Framework.

Given the growth of the industrial sector, and the increase in capabilities, both in production and connectivity, thanks to the consolidation of Industry 4.0 and the emergence of Industry 5.0, industrial environments are in the focus, not only of technological improvements, but also of cyber-attacks.

The application and implementation of the IEC 62443 family, in combination with the NIST Framework, will enable organizations to reduce, mitigate and control the possibility of suffering a cyber-attack by implementing the controls and best practices defined in both standards.
