Brands named, in the order the engine gave

1. Microsoft Purview DLP mentioned
   Microsoft Purview DLP (if you're on Microsoft 365) - If you have Business Premium, basic DLP for Exchange, SharePoint, OneDrive and Teams is already included, along with manual sensitivity labels.

The answer, as recorded

## Start with what you probably already pay for **1. Microsoft Purview DLP (if you're on Microsoft 365)** - If you have Business Premium, basic DLP for Exchange, SharePoint, OneDrive and Teams is already included, along with manual sensitivity labels. That's zero extra spend and it covers the single biggest small-business leak path: email and file sharing. The catch is that **Endpoint DLP (USB drives, copy/paste, local file moves) is not in the base Business Premium plan** - Microsoft now sells a Purview Suite add-on for Business Premium tenants to unlock that. Try this first; only buy a third-party tool if it genuinely doesn't cover you. [microsoft.com/security/small-medium-business/microsoft-purview-suite-business-premium](https://www.microsoft.com/en-us/security/small-medium-business/microsoft-purview-suite-business-premium) · [learn.microsoft.com Q&A](https://learn.microsoft.com/en-us/answers/questions/1124589/does-microsoft-purview-dlp-comes-with-microsoft-36) **2. Google Workspace DLP (if you're on Google)** - Worth knowing up front: DLP is gated to the **Enterprise** tiers, not Business Standard or Business Plus. So Google shops usually can't just "turn it on" the way M365 shops can - you're either upgrading the whole tenant or buying a third-party tool. For most small teams, the third-party tool is cheaper. [workspace.google.com/pricing](https://workspace.google.com/pricing) ## If you need a real, dedicated DLP tool **3. Safetica** - My default recommendation for an SMB buying standalone DLP. Starts around **$4.50-5/user/month**, published pricing, no appliance, no mandatory professional services. It combines DLP with insider-risk analytics, which is the thing small teams actually worry about (departing employee copying the client list). Fastest path from purchase to working policies.

Netwrix Endpoint Protector (formerly CoSoSys)** - Pick this over Safetica if your risk is **physical/device-level**: USB ports, external drives, printers. It's the strongest device-control DLP in this price class and it's genuinely cross-platform - Windows, macOS *and* Linux, which matters if you have designers on Macs or engineers on Linux. Pricing is quote-only, which is the main annoyance. [currentware.com/blog/best-data-loss-prevention-software](https://www.currentware.com/blog/best-data-loss-prevention-software/) **5. Nightfall AI** - The right answer if your sensitive data lives in **SaaS and cloud, not on laptops** - Slack, Jira, Salesforce, Notion, GitHub, plus API-level scanning. It's cloud-native and ML-based rather than agent-based, so there's nothing to install on endpoints. Choose it if you're a remote-first or software company; skip it if your exposure is people walking out with USB sticks. Pricing is quote-based; treat any "starts at" number you see online as a third-party guess. [currentware.com/blog/best-data-loss-prevention-software](https://www.currentware.com/blog/best-data-loss-prevention-software/) **6. CurrentWare** - Cheapest realistic entry point, sold as modules (device control, web filtering, activity monitoring) so you can buy just the piece you need. It's more monitoring-with-DLP-features than true content-inspection DLP - fine for a 15-person shop, thin if you have a real compliance obligation. [currentware.com/blog/best-data-loss-prevention-software](https://www.currentware.com/blog/best-data-loss-prevention-software/) ## What I'd skip **Forcepoint, Symantec/Broadcom DLP, Digital Guardian, Trellix.** These are excellent enterprise products and they show up on every "best DLP" listicle, but they carry appliance costs and professional-services fees that don't amortize under a few hundred seats. You'll spend more on deployment than on licenses, and you'll need someone to run it. ## Practical advice Two things matter more than the product choice: - **Run in monitor-only mode for 30 days before you block anything.** Every DLP tool over-triggers at first. Blocking on day one means your sales team can't send a contract and the tool gets switched off by week two. - **Scope to one or two data types.** Pick the data that would actually hurt - customer PII, or the pricing sheet, or source code - and write policies for that. Small businesses that try to classify everything end up classifying nothing. If you tell me which email platform you're on and roughly how many employees, the shortlist collapses to one or two. **Sources:** - [Microsoft Purview Suite for Microsoft 365 Business Premium](https://www.microsoft.com/en-us/security/small-medium-business/microsoft-purview-suite-business-premium) - [Does Microsoft Purview DLP come with Business Premium? - Microsoft Q&A](https://learn.microsoft.com/en-us/answers/questions/1124589/does-microsoft-purview-dlp-comes-with-microsoft-36) - [Google Workspace pricing and plan comparison](https://workspace.google.com/pricing) - [15 Best Data Loss Prevention (DLP) Software in 2026 - CurrentWare](https://www.currentware.com/blog/best-data-loss-prevention-software/) - [DLP Pricing: Compare Top 5 Vendors - AIMultiple](https://aimultiple.com/dlp-pricing) - [Top 14 Data Loss Prevention Tools Compared for 2026 - miniOrange](https://www.miniorange.com/blog/top-data-loss-prevention-tools/)
