Split Tunneling is a core network security concept that every cybersecurity and GRC professional should understand.
What Is Split Tunneling?
Split Tunneling refers to the practices, processes, or technologies related to split tunneling within the context of information security and risk management. Understanding split tunneling helps organizations protect their systems, data, and operations from relevant threats.
How It Works
Split Tunneling is applied through a combination of policies, technical controls, and organizational procedures. Security teams implement split tunneling as part of a broader security program aligned to industry frameworks and regulatory requirements.
Why It Matters
Organizations that correctly implement split tunneling reduce their exposure to cyber risk, improve regulatory compliance, and strengthen their overall security posture.
Key Takeaways
- Understand what split tunneling is and how it applies to your organization’s security program.
- Align split tunneling practices to a recognized framework such as NIST CSF, ISO 27001, or CIS Controls.
- Regularly review and test controls related to split tunneling to ensure they remain effective as threats evolve.
