Our company is looking for a centralized secure share solution. We've so far looked at Box and Egnyte.  We currently have OneDrive and want to see if we should expand on so that we could manage/monitor sensitive data.  We are at a crossroads.  Any insight?

We’ve been evaluating similar needs in our organization and reached a similar crossroads. What really helped us was mapping use cases versus controls looking beyond simple file storage to how we monitor, classify, and audit sensitive data across teams. Box and Egnyte both offer strong security and governance capabilities, but if you’re already deeply invested in Microsoft 365, expanding OneDrive with tools like Microsoft Purview and Defender for Cloud Apps can also provide robust data protection and visibility without introducing another platform.

A few practical questions helped clarify our direction: do you need file-level classification and automated policy enforcement, how critical is secure external collaboration, and what level of real-time activity monitoring and alerting is required? If your priority is built-in governance and minimizing tool sprawl, extending OneDrive with Microsoft’s compliance stack can be very effective. If you need more specialized auditing or support for a broader, non-Microsoft ecosystem, Box or Egnyte may be a better fit. Happy to share more detail on how we approached this if that’s useful.

What if you looks at OneDrive again plus adding security monitoring or other management with other tools rather than have docs in 2 places?

OneDrive will give you an easier integration with Purview for your DLP, sensitivity labels, and policy enforcement, which is hard to beat if your stack is already Microsoft. Egnyte is going to be stronger for device-aware access controls (think like blocking downloads based on IP, device trust, or user risk). 

Box Governance is strong for legal hold and audit logging, but OneDrive needs Purview Premium to match that, and then you're spending more. ing experiences.

Egnyte will give you an easier path on data separation between departments or business units. OneDrive makes that harder without spinning up new tenants.

OneDrive’s will be cheaper in the long run. Box and Egnyte might be able to reduce shadow IT because they are have better external sharing experiences - these will be stronger than SharePoint extneral for example).

I like both Box and Egnyte.  The problem you (and I) have is that neither of those vendors can tell you what constitutes "sensitive data".  

Look at what your current tools are and what would integrate with the products you are evaluating. That along with cost would help you decide.
