SSL is the beginning, not the end
An SSL certificate encrypts communication between a visitor and a website, but it cannot stop malicious code, vulnerable applications or unauthorised access on its own. Effective security requires several layers working together.
Regular updates, strong credentials, controlled access, malware protection, reliable backups and ongoing monitoring all reduce risk. The goal is not to depend on one security product, but to combine multiple safeguards so that a single weakness is less likely to become a serious incident.
