Meanwhile I am looking for good (but without user based pricing) SaaS or open source tool to securely handle PII data and consent management. So far I have encountered this open source tool, if someone has any pointers or blogs around design such a system please share - https://databunker.org/

BigID I believe has a product called SmallID that would likely be a fit here. https://bigid.com/data-security-posture-management/. Can access directly through AWS marketpalce

Thanks @Shomik Ghosh
