Can you elaborate? My understanding is your security posture determines how well you mitigate, identify, contain, and repel attacks.
In the same way your sales posture determines how well you identify, qualify and convert leads and your product posture determines how well you design, execute and market-fit your products - yet somehow we never felt the need to add 'posture' to these.
The end result is another obfuscation layer of corporate-speak on something that should be pretty concise and bullshit-free.
