ASIO-T4 is responsible for certifying the physical security of Australian Signals Directorate Certified Gateway Service Provider facilities. These security certified facilities including data centres and data halls are intended for use by multiple Australian Government agencies.

ASIO-T4 provides an ongoing specific advisory service for Government clients, on how best to protect their people, information and physical assets. This advice is tailored to address individual and specific requirements.

These involve a comprehensive review of security threats and the development of recommended protective security measures, using risk-based methodology. ASIO-T4 has direct access to threat-based risk information in the risk review process, so as to assess all known potential sources of security risks. Recommendations will typically include physical, electronic, administrative, and procedural security measures to manage the risk.
