Advanced cyber threats, such as tunneling attacks, are increasingly sophisticated and targeting critical infrastructure across Southeast Asia, including Singapore, Malaysia, and Indonesia. Anti Tunneling techniques aim to identify and block covert data exfiltration methods, but their effectiveness depends on robust monitoring. Data Diode Cyber Threat Analytics provides a unidirectional data flow system, ensuring secure network communication while continuously analyzing traffic for anomalies indicative of tunnelling attempts. Wynyard Group leverages these analytics to enhance threat visibility, enabling organisations to detect complex intrusions early. By integrating Anti-Tunnelling measures with Data Diode Cyber Threat Analytics, businesses in the region strengthen their resilience against evolving cyberattacks.
