How Zero Trust Network Access (ZTNA) improves SaaS application security

SaaS applications have become a staple of modern IT environments; M365, Zoom, Salesforce, Dropbox, the list of SaaS applications that have gained a strong foothold is endless. However, the adoption of SaaS applications has outstripped securing them and companies of all sizes are still figuring out how to best secure their cloud environments.

SaaS application security is complex. A fixed network perimeter approach to security will not suffice for SaaS applications. These applications are typically exposed to the public internet, which puts them at greater risk, traditional network security technologies will do little to protect these services.

As workloads move away from on-premises environments, security needs to as well. Zero Trust Network Access (ZTNA) has been touted as a way to provide secure access to SaaS applications. ZTNA enables businesses to remove applications and services from direct visibility of the public internet, thereby mitigating the threat of account takeovers where login credentials have been stolen or password-based attacks have been enacted.

ZTNA eliminates the distinction between being on and off the corporate network, normalizing the user experience for application access.

The leading analyst firm Gartner has touted ZTNA as a suitable solution for secure access to applications, addressing the security, manageability and user experience challenges.
