WPA3 provides enhanced security features compared to WPA2, including improved protections against brute-force attacks and better data encryption. WPA2, while still secure, is older and potentially vulnerable to security exploits that have been addressed in WPA3. WEP is outdated and highly insecure, with many vulnerabilities that can be exploited easily. WPA-PSK offers a decent security level but lacks the advanced features and strength of WPA3, making it less ideal for environments requiring robust security measures.
