PR application is stuck at Security assessment

[manp1988]

Hi,

I received my PR ITA on Dec 2023 and submitted my documents on Feb 2024. I received my AOR on the same day. My medical and biometrics are also completed but it's been months and I haven't received the P1 email. I reached out to a local MP to get the status of my application and he shared the below update.
My spouse and child are also in the same application. None of us received COPR yet.

• The Criminality, Medical, and Eligibility assessments have all been successfully passed.
• The Security assessment is still in progress.
• There have been no new updates since our last communication.
• Please note that a processing time is not applicable due to the ongoing Security assessment.

I don't know what "Security assessment " is. Does anyone know what it means and how can I expedite this process by providing additional documents?

Thanks!
