What does it mean when a women wants a man to make her feel safe

Was on a date. My dating is very hard to navigate. So new. I asked my date what is she looking for in a man. She said first and foremost a man that makes her feel safe. I asked exactly what she meant by that. She replied "you know safe" Not to seem like a dope I just agreed. With my ex-wife her emotional mental and physical safety were my top priority. She knew I always had her back.
