The SCP Foundation is above the government and the world's most powerful organization. They Secure Anomalies and keep them in their Foundation Facilities to study them and learn more about the SCPs. They contained hundreds of thousands of Anomalies over the decades. The Foundation is Cold, but not cruel. They often conduct interviews with some Anomalies to learn more about them.
'Secure, Contain, Protect' is their motto.
