The full name of SCP Foundation is Special Containment Program Foundation, which is a global secret organization. Their goal is to contain and destroy supernatural objects/people/phenomena (SCP) around the world, so that ordinary people can live in a relatively safe world. The activities of the SCP Foundation are completely free from the interference of major national governments (and the Foundation is very, very rich), but in some cases, the Foundation will choose to cooperate with major national governments to achieve its goals. The work of SCP Foundation is to contain these threatening things, control them and prevent them from causing harm. Just like the men in black in the movie MIB catch aliens and control them. This is a legendary organization, and no one knows whether it exists. By definition, scp is called the international secret service organization.
The first level, the highest level, is called keter. This level of monsters can hardly be accommodated, which is extremely difficult and aggressive. Monsters that can pose a great threat to human beings, so for monsters of this level, since scp can't accommodate them, they will actively consider destroying these things. If it can't be destroyed, try to control or monitor it.
The second level, the middle level, is called Euclid. Then, this level of monsters can be accommodated, but we don't know enough about them, so we can't be sure whether they are safely accommodated. It will pose a threat to mankind, but it is not as powerful as Kurt, or has self-restraint ability.
The third layer, that is, the bottom layer, is called security. Then, this level of monsters can be safely kept in captivity. Does it feel that a safe monster is not a threat? But don't underestimate the level of safety. This level of monster is almost equivalent to a nuclear bomb, but the control of this nuclear bomb is in our hands. Similarly, we can see how horrible the first two levels are, and they may be blown up at any time, so we need to destroy them.
In addition to the above three security levels, there are four special levels. The fourth level is called Thaumiel level. Monsters of this level are particularly rare, and monsters of Kurt level can be restrained. It is a monster that can be controlled by scp. It may also be a Kurt level, but it may be similar to another Kurt level monster.
The fifth special level: unclassified, called undefined level. It shows that the level of this monster is still unknown.
The sixth special level: neutrality, which is called neutral level. Neutralization means that this monster's ability has been destroyed, and it is no longer destructive, so why should it become scp level since it is not destructive? Mainly because this ability has disappeared, I don't know if it will recover.
