If you want a lighter-weight alternative to OneTrust, the “best” choice usually depends on what you actually need it for:
- Cookie consent / CMP only
- Privacy request management (DSARs)
- Basic vendor risk / RoPA
- Full enterprise privacy program
Best lightweight picks by use case
1) Cookie consent / CMP only
- Cookiebot
- iubenda
- Termly
- Osano
These are much simpler to deploy than OneTrust and are popular for websites that mainly need consent banners, preference management, and cookie scanning.
Best overall lightweight choice here: Cookiebot
It’s straightforward, widely used, and focused on consent management rather than a huge privacy suite.
2) Lightweight privacy operations / DSARs
- Osano
- Transcend
These are better if you want requests, tracking, and automation without OneTrust’s bulk.
Best overall lightweight choice here: Osano
It tends to be easier to set up and operate than OneTrust while still covering core privacy workflows.
3) Affordable small-business privacy compliance
- Termly
- iubenda
These are usually the easiest and cheapest to get running for smaller teams.
Best overall lightweight choice here: Termly if you need something simple and budget-friendly.
