Endpoint DLP on Linux fleet: Forcepoint vs Purview
Posted by tingnossu@reddit | linuxadmin | View on Reddit | 10 comments
Our org runs a mixed fleet, about 60% Linux, rest Windows and macOS, and we're, in the middle of replacing a legacy DLP setup that basically ignored anything not running Windows.
Constraints: mid-market budget, two-person security team, already deep in Microsoft 365 but not locked into Purview, and we need, USB control plus content inspection to actually work on Ubuntu and RHEL endpoints, not just check a compliance box.
Forcepoint's Linux agent support is unclear from what I've been able to find - their endpoint protection seems, to be documented for Windows and Mac only, so if anyone has real-world experience there I'd love to know. Microsoft Purview is the obvious fit for our M365 stack but I haven't been able to get a, straight answer on where their endpoint story actually lands for non-Windows, and I'm not fully confident in it. We also looked briefly at Netwrix DLP but couldn't find much verified information about their Linux support at all, which makes it a harder sell to leadership regardless.
Priority order for us: reliable Linux agent, USB and peripheral control, content-aware policies that don't need a full-time tuner, and decent M365 integration.
Curious specifically how others with Linux-heavy fleets are handling the Purview gap right now, and whether Forcepoint's Linux support has actually held up in production.

The Linux gap is real across most DLP products.
In practice, the biggest issue usually isn’t policy creation, it’s keeping the Linux agent stable across kernel updates, desktop environments, and USB behavior differences between distros.
Forcepoint’s Linux support exists, but I’d strongly test it against your exact Ubuntu/RHEL versions before committing.

Agreed! And this is exactly why USB control on Linux is better handled at the kernel level with udev rules or through your EDR (CrowdStrike has solid USB policy support) rather than relying on a DLP agent that has to survive every kernel update. Keep the DLP layer for content inspection on Windows and Mac where the agents are mature, and solve Linux USB control separately with tooling that was actually built for it.

Yeah, that’s usually where things get messy on Linux.
The agent works fine… until a kernel update or distro difference suddenly changes behavior nobody expected.

Purview's Linux endpoint support is still catching up and not production-ready for USB control on Ubuntu/RHEL, Forcepoint's Linux agent exists but is inconsistently documented for a reason, for a Linux-heavy fleet with a two-person team, OpenDLP or Safetica are worth a serious look, and for USB control specifically, udev rules plus CrowdStrike's USB policy enforcement is the most reliable path right now without adding another agent.

Just don't give them root and put USB modules in the deny list or extend the AppArmor/SELinux settings?

Those controls help harden the endpoint but they're not DLP - you still get zero content inspection or classification, so anything leaving through allowed channels like email attachments, browser uploads, or sync clients is completely invisible to you.

I didn't see any that it's a full DLP, it can certainly solve a part of your problem.

If USB control and peripheral management on Linux is the bigger pain point, Scalefusion might be worth a look. The Linux agent works on Ubuntu and RHEL and it handles mixed fleets (Linux + Windows + macOS) from a single dashboard.
tingnossu@reddit (OP)
Peripheral control on mixed fleets is a real headache and Scalefusion might help there, but our bigger gap is content inspection and policy enforcement around sensitive data movement, which MDM and UEM tools generally don't cover fully on Linux since that's still where even dedicated DLP solutions like Purview fall short compared to something like Forcepoint..
