The answer, as recorded

For most small businesses, the honest first answer is: don't buy a standalone DLP product until you've turned on the one you're already paying for. Here's the order I'd actually work through. **1. Microsoft Purview DLP (if you're on Microsoft 365)** Business Premium already includes baseline DLP (Exchange Online, manual sensitivity labels) at no extra cost - so the first move is configuring policies, not procurement. If you need real coverage (endpoint DLP, insider risk, auto-labeling), the Purview Suite add-on for Business Premium is ~$10/user/mo on top of the ~$22 Business Premium seat, roughly half the cost of jumping to E5. Best fit-to-effort ratio of anything on this list if your data lives in M365. ([Microsoft](https://www.microsoft.com/en-us/security/small-medium-business/microsoft-purview-suite-business-premium), [CIAOPS breakdown](https://blog.ciaops.com/2025/10/03/microsoft-purview-suite-for-business-premium-features-smb-use-cases/)) **2. Google Workspace DLP (if you're on Google)** Same logic. DLP for Drive, Gmail, and Chat is built in, with Gmail DLP now generally available. The catch is edition-gating - the useful rule depth lands in Business Plus and above, so a 5-seat Business Starter shop may need an upgrade before this is real. ([Google Workspace Updates](https://workspaceupdates.googleblog.com/2025/02/gmail-data-loss-prevention-general-availability.html), [Strac guide](https://www.strac.io/blog/google-workspace-dlp)) **3. Safetica** The one I'd name first among dedicated SMB products. It's built for teams without a security engineer: data discovery, classification, endpoint monitoring, and insider-risk analytics with a genuinely manageable admin burden. Public figures put it around $4.50-5/user/mo, though it's quote-based so treat that as an estimate. Pick this if you have Windows/macOS endpoints and worry about employees moving files to USB, personal Drive, or webmail. ([Currentware roundup](https://www.currentware.com/blog/best-data-loss-prevention-software/), [Safetica pricing](https://www.spotsaas.com/product/safetica/pricing)) **4. Netwrix Endpoint Protector (formerly CoSoSys)** The one to shortlist against Safetica when device control is the actual requirement - USB/peripheral blocking, and strong Linux and macOS support, which is where most SMB-tier DLP falls over. Pricing is request-only. ([Currentware](https://www.currentware.com/blog/best-data-loss-prevention-software/)) **5. Nightfall AI** Different shape of problem: API-based scanning of SaaS and cloud apps (Slack, Google Drive, GitHub, and increasingly AI tools) rather than agents on laptops. Right choice for a small SaaS or dev-heavy company whose leak risk is a secret pasted into Slack, not a file copied to a thumb drive. Also quote-based. ([Currentware](https://www.currentware.com/blog/best-data-loss-prevention-software/), [Nightfall](https://www.nightfall.ai/blog/safetica-dlp-comprehensive-analysis-and-top-alternatives)) **Skip unless you have a dedicated security team:** Forcepoint, Symantec DLP, Digital Guardian, Proofpoint. Capable enterprise platforms, but the deployment and tuning cost will eat a small business - the common failure mode is buying one and leaving it in monitor-only mode forever. ([Forcepoint's own comparison](https://www.forcepoint.com/blog/insights/best-dlp-software) is a decent read on why packaging makes DLP pricing so hard to compare.) Two caveats worth stating plainly: nearly every vendor here hides pricing behind sales, so any per-seat number above is an estimate, not a quote. And most of these "best of 2026" listicles are vendor-run content marketing - I used them for the shortlist, not the rankings.
