In Go, a map is not safe for concurrent use, meaning if multiple goroutines access a map concurrently and at least one of the goroutines modifies the map, the behavior is undefined. On the other hand, sync.Map is designed for safe concurrent access. It provides concurrency safety through synchronization mechanisms internally, making it suitable for concurrent use. This difference is crucial when designing concurrent applications in Go.
