The invention relates to the technical field of network security, and provides a segmented data detection method and a corresponding device. The method comprises the following steps: firstly, acquiring to-be-detected data, and vectorizing the to-be-detected data to obtain a corresponding target coding vector; processing the target coding vector to obtain an abnormal score value of the to-be-detected data; comparing the abnormal score value with a segmentation threshold value, and determining whether the to-be-detected data is normal data or suspicious data according to a comparison result; and if the to-be-detected data is suspicious data, inputting the coding vector into a classification model, and judging whether the to-be-detected data is normal data or malicious data through the classification model. According to the method, a two-section type detection scheme is used for detecting the data, normal data are rapidly screened out firstly, then subsequent detection with high accuracy is conducted on a small
