The answer, as recorded

For a small business, the honest first move is usually "use what you already pay for" before buying a dedicated DLP product. Here's how I'd rank them: **1. Microsoft Purview DLP (if you're on Microsoft 365 Business Premium)** Already included - no new vendor, no new agent. You get DLP policies across Exchange, SharePoint, OneDrive, and Teams plus sensitivity labels and encryption, roughly at Office 365 E3 parity. That covers the most common real-world leak paths (someone emailing a customer list, sharing a folder too broadly). Advanced DLP, insider risk management, and endpoint-heavy features need the Purview Suite add-on at ~$10/user/month. Start here; only look further if it genuinely doesn't cover you. **2. Safetica** - the best true SMB pick if you need a dedicated tool Purpose-built for small and mid-size companies: quick setup, readable policies, and insider-risk visibility (who's touching what) without a full-time admin. It consistently outrates its peers on value-for-money and likelihood-to-renew. Caveat: no Linux agent. **3. Netwrix Endpoint Protector (formerly CoSoSys)** - pick this over Safetica if you have mixed OS or USB/device worries Strongest device-level control in this tier: USB ports, external drives, printers, plus content-aware blocking. Full Windows/macOS/Linux coverage and flexible deployment (SaaS, cloud, virtual appliance). From about $9/user/month. This is the one for a design studio, lab, or shop floor where data walks out on thumb drives. **4. Nightfall AI** - if your sensitive data lives in SaaS, not on laptops API-based scanning of Slack, Google Drive, Jira, GitHub, etc., with good detection for secrets, PII, and data pasted into AI tools. No endpoint agents to manage. From ~$10/user/month billed annually. Best fit for a cloud-first startup. **5. CurrentWare** - cheapest useful option with a real trial ~$12/user/month, 14-day free trial, bundles endpoint DLP, USB control, and employee activity visibility. Worth a look if budget is the binding constraint, though be deliberate about the monitoring features - they can create HR and privacy problems you didn't ask for. Two things I'd skip at small-business scale: Forcepoint, Netskope, Zscaler, and Cyberhaven are excellent but priced and staffed for enterprises. And note that backup tools like NinjaOne get marketed as "data loss prevention" - they protect against accidental deletion, which is a different problem from stopping data from leaving. If you need both, buy both; don't let one stand in for the other.
