SaaS vs on-prem software: which is better for enterprises?

SaaS handles maintenance, upgrades, and hosting for the enterprise, enabling fast updates, remote access, and reduced IT dependency, but it may raise data sovereignty concerns or limit customisation. On‑prem gives firms full control and often better data privacy, but it requires larger IT resources and can slow scaling. Enterprises choose SaaS for flexibility, but opt for on‑prem to enforce strict controls or comply with regulations.
