    Offsite Accessibility:


    As part of the Laboratory’s ongoing efforts to improve cyber security, TREX requirse VPN for off site access. Users can get more information about VPN installation at the IT VPN help page and get assistance at IT Help. VPN service is provided at no charge for all LBNL employees and affiliates.


    Limiting access to the TREX application to those on our network or using VPN helps to limit the exposure of the application to hostile attackers on the internet. Applications exposed on the internet are subject to constant attack, and while LBL’s security systems help to reduce this exposure, IT judged that further reducing this risk was appropriate for TREX at this time.


    If you have questions about VPN or feedback about this change, please visit IT Help.


    Old TREX Records:


    Authorizations and expense reports created in the old TREX system are available as "View Only".
