The answer, as recorded

For a small business, the honest first answer is: check what you already own before buying anything. Most SMB data leaks happen through email and cloud file sharing, and both Microsoft and Google already ship DLP for that. **1. Microsoft Purview DLP (if you're on Microsoft 365)** - Start here. Basic DLP for Exchange, SharePoint, OneDrive and Teams is already included in Microsoft 365 Business Premium, so the marginal cost is zero. It covers the common cases: credit card numbers in outbound email, sensitive files shared externally. The gap is auto-labeling and insider risk, which need the Purview add-on (~$10/user/mo for Business Premium tenants, or ~$15 bundled with Defender). For most sub-100-person companies, the included tier plus a few well-written policies is genuinely enough. **2. Google Workspace DLP (if you're on Google)** - Same logic. DLP for Drive and Gmail is bundled into Business Standard/Plus and Enterprise tiers. Don't pay a third party for something your existing subscription does. **3. Endpoint Protector by Netwrix (formerly CoSoSys)** - The one to buy if your real risk is physical: USB drives, external storage, printing. It's the strongest device-control DLP in the SMB price range and the best cross-platform story - Windows, macOS *and* Linux agents that are actually at parity, which matters if you have a mixed shop. Also available as a cloud-hosted deployment so you're not standing up a server. **4. Safetica** - The friendliest option if you want endpoint DLP plus insider-risk visibility and don't have a dedicated security person. Roughly $4.50-$5/user/month, ready-made policy templates, and a UI reviewers consistently like. The recurring complaints are deployment time and endpoint performance overhead, so pilot it on a handful of machines before you roll it out fleet-wide. **5. Nightfall AI** - Pick this only if your sensitive data lives in SaaS: Slack, Notion, Jira, GitHub, Salesforce. Its ML-based detection has noticeably fewer false positives than regex-driven legacy tools, which matters a lot when one person is triaging alerts. Two caveats: it does nothing for USB/removable media, and real-world small-team contracts land around $8K-$20K/year, so it's not cheap for a 20-person company. **6. CurrentWare** - Worth a look if budget is the binding constraint. Modular (you buy just the device-control or web-filtering piece), on-prem or cloud, and priced below the others. Less sophisticated content inspection, but it's real DLP rather than a toy. A note on the category: much of what gets published as "best DLP" listicles is affiliate-driven, and vendors like Kickidler that market as DLP are substantially employee-surveillance tools - screen recording and keystroke logging. That's a different product with different legal exposure depending on your jurisdiction and whether staff are notified. Buy it deliberately if you want it, not because a comparison table filed it under DLP. My default recommendation: turn on what's in your Microsoft or Google tenant this week, run it in audit-only mode for a month to see what actually trips, then decide whether you need Endpoint Protector (device risk) or Nightfall (SaaS risk) on top. Buying an agent before you know your leak paths usually produces alert fatigue and a shelfware renewal.
