  • The materials provided to members through TX-ISAO channels are for informational use or purposes only. Any thoughts, ideas, opinions, notifications, advisories, or recommendations shared are offered solely for member consideration and may not be relevant to your entity or apply to the member's circumstances or incident.
  • Any third-party views and opinions do not necessarily reflect those of DIR or its employees. By sharing this material, DIR does not endorse any particular person, entity, vendor, product, application or software, opinion, recommendation, or service.
  • A private company must not use information received through TX-ISAO channels about a governmental entity's needs or security issues to obtain an unfair competitive advantage. A private company is also prohibited from directly contacting or reaching out to a governmental entity regarding solutions to governmental entity needs or security issues based upon information obtained or learned from TX-ISAO channels.


Please indicate at the point of your registration for TX-ISAO membership whether you are associated with a public or private sector entity. These terms are defined as follows:

Please indicate to which sector(s) you would like access. These sectors dictate which TX-ISAO channels and communications you are able to access or receive. While both public and private sector entities are able to be members of the TX-ISAO, access to certain sector TX-ISAO channels may be restricted to particular membership sectors at DIR's discretion due to the sensitive and specific nature of the materials found therein. DIR will determine whether to grant a member's request to access a restricted sector. DIR's decision on restricted sector access is final.

If you receive access to a TX-ISAO channel or communication to which you believe you should not have been granted access or received, notify DIR at ISAO@dir.texas.gov immediately upon identification of the potentially improper access.
