SaaS products use cloud servers — that’s the core of SaaS. Cloud servers are considered way more secure than local servers by default, as server providers take care of security in the cloud. While requiring no extra effort on your part, cloud-based software is believed to be safer and more secure than software running on traditional servers. However, it wouldn’t be sensible to forego both a security audit and implementing extra security measures custom-made for your SaaS platform if it deals with sensitive data.
