Unless you *know* your company’s systems are extremely secure, don’t go around the Internet or in public telling people their data is secure with you.
If you don’t know about security and are using it as a talking point because it’s important to people, don’t talk about it. You are inviting criminals to attack you and your systems just for the fun of it. Your systems are primarily secure because you’re not being actively targeted. If someone or a group wants to get into your systems, they’ll find a way. Don’t put a target on yourself. It will cost you and your business.
