IPsec has three protocols Authenticated Header (AH), Encapsulating Security Payload (ESP), and IP Compression (IPComp). In a short explanation AH adds a message authentication check to the header ensuring integrity of the payload. ESP encrypts the payload following the IPsec header making it safer from sniffing, and also adds a message authentication check.
