ConsentOS vs OneTrust
Which cookie consent tool fits your site best?
The comparison between Consentos and OneTrust is perhaps the biggest contrast in the privacy software market. You are comparing free, do-it-yourself "wood and nails" with a fully built skyscraper in the enterprise segment.
Where they are identical
Despite the immense difference in execution, they do exactly the same for the end-user on your website. Both platforms present the visitor with a banner, legally store the given consent, and prevent external marketing scripts like those from Facebook or Google from loading until the visitor agrees.
Where the difference lies
Scope. Consentos is purely focused on the banner. It is a bare open-source framework that must be installed on your own server(s) by developers. It has no automatic scanners and no policy generators. OneTrust is a market leader in enterprise data governance. The cookie banner is merely a side issue in their overarching cloud platform that also facilitates internal risk audits, data mapping, and vendor management for thousands of employees.
Complexity. OneTrust requires serious technical consultancy to integrate into the cumbersome systems of a multinational, but subsequently offers complete, worldwide relief via the cloud. Consentos also requires complex implementation, but purely in the form of raw coding by your own web developers (since you have to build everything yourself).
Budget. Consentos is completely free in terms of software licensing. The costs are entirely in your developers' hours. OneTrust focuses exclusively on enterprise budgets with often modular, annual contracts starting around $1000 per month.

Our recommendation
For independent tech agencies and development teams, Consentos is an option. It requires a lot of manpower, but you are freed from subscription costs and you are 100% 'in control' of your data, without cloud parties.
Choose OneTrust exclusively if you work for a gigantic enterprise or multinational where the cookie banner forms only a small part of a much broader, company-wide data governance strategy, including the corresponding gigantic budgets.
Setting up a banner does not equal compliance. Most violations occur post-installation because scripts still load too early via Google Tag Manager. Always run a free scan after configuration to verify it actually works.
