How does Web security enhance my dental care experience?

Web security is a key issue that everyone is suffering from. I found using web security confusing when booking my online dental appointment because I didn't trust whether these websites were fully reliable or had any security policy and I wasn't sure how my personal information, transactions, or sensitive details were protected. However, with trusted web security, I am exploring options where I feel secure and confident while using websites, especially when I manage dental hygiene, from an online booking system to schedule an appointment at dental clinics. I was also worried about privacy concerns. If someone guides me, is web security playing a key role in enhancing my overall dental experience?
