Microsoft Purview DLP India
Microsoft Purview DLP India: The Data Loss Prevention You May Already Own
One mis-sent email can put customer data in the wrong inbox. If your team runs on Microsoft 365, the tool to stop that is likely already in your licence. We turn it on, tune it, and keep it working so the leak does not happen on your watch.
The leak you cannot see is the one that hurts
A finance executive at a Pune services firm forwarded a salary sheet to the wrong vendor. It took one autocomplete in the To field. By the time anyone noticed, the file had sat in an outside inbox for a week. No alarm went off. Nobody knew until the vendor mentioned it.
That is the quiet risk most Indian businesses carry. Data does not usually leave in a dramatic hack. It walks out in normal email, a Teams chat, a shared OneDrive link, or a file copied to a pen drive. The person doing it rarely means harm. The damage is the same either way.
Microsoft Purview DLP is built to catch exactly this. It reads content as it moves and stops the risky moves before they complete. The best part for an Indian Microsoft 365 customer is simple. You may already be paying for it and not using it.
I keep coming back to one thing in every assessment we run in 2026. The control the business needs is almost always already sitting in the licence, switched off. Nobody turned it on because nobody had the time. That is the gap we close.
What Microsoft Purview DLP actually does
Purview DLP is a set of rules that follow your sensitive data wherever it travels inside Microsoft 365. You tell it what to protect. It then watches for that data and acts when someone tries to send it somewhere it should not go.
It can warn the user, block the action, or quietly log it for review. You can scope rules by person, by team, or by data type. Microsoft documents the full policy model on Microsoft Learn, and we configure it to your real workflows, not a generic template.
The data types matter for India. Purview can detect PAN numbers, Aadhaar numbers, bank account details and card numbers, so the rules map to what the DPDP Act and RBI actually care about.
Across the whole estate
Email in Exchange, chats in Teams, files in SharePoint and OneDrive, and content on Windows endpoints. One policy set, one console.
Built into M365
No new agent to buy if you are on the right plan. It uses the Microsoft 365 you already run, so rollout is faster than a bolt-on tool.
Evidence for auditors
Every policy match is logged. When an auditor or your insurer asks what controls you have, you have a clean record to show.
Three places Purview DLP stops data walking out
Email and chat
It catches a salary sheet, a customer list or a card number before it leaves in an email or a Teams message. The user gets a clear nudge or a hard block.
Cloud files
It stops a sensitive file in SharePoint or OneDrive from being shared with the wrong people or a personal account.
Endpoints
On Windows devices it can stop a confidential file being copied to a USB drive, printed, or pasted into a personal web app.
Microsoft Purview DLP India pricing and licensing routes
How you pay for Purview DLP depends on the Microsoft 365 plan you already hold. There are three common routes for Indian businesses.
| Your Microsoft 365 plan | DLP position | What we do | Indicative |
|---|---|---|---|
| Microsoft 365 E5 | Purview DLP is already included | Configure and tune policies across mail, Teams, SharePoint, OneDrive and endpoints | Setup from ₹25,000, no extra licence |
| Microsoft 365 E3 | Add the E5 Compliance pack for full DLP | License the add-on, then configure and tune | Add-on priced to your agreement, plus setup |
| Business plans or mixed estate | Native DLP is limited | We assess Purview against Secure Data Guard and recommend the cheaper fit | Quote after a free DLP health check |
Figures are indicative and exclude GST. Microsoft licence costs depend on your agreement and current Microsoft pricing. We confirm exact numbers after a short assessment. Source: Microsoft 365 licensing.
Purview DLP or Secure Data Guard: which fits you
| What matters | Microsoft Purview DLP | Secure Data Guard |
|---|---|---|
| Best when | You already run Microsoft 365 E5 or E3 | You have a mixed estate or no M365 |
| Coverage | Deep inside the Microsoft 365 world | Broad across mixed apps and devices |
| Extra licence | None on E5; add-on on E3 | Stand-alone, priced per seat |
| Setup effort | Lower if you are already on M365 | Independent of your mail platform |
| Who tunes it | Our team, from Navi Mumbai | Our team, from Navi Mumbai |
We sell and support both, so the advice is honest. If you are deep in Microsoft 365, Purview is usually the cheaper, faster path. If you are not, we will say so.

How we deploy Purview DLP, step by step
Turning DLP on is the easy part. Turning it on without breaking real work is the skill. Here is the path we follow with every client.
1. Find the data
We map where your sensitive data lives and which rules the DPDP Act and RBI expect. That sets the policy scope.
2. Start in test mode
We run policies in audit-only mode first. You see what would trigger, with no blocks, so nobody is surprised.
3. Tune the noise
We cut the false alarms. A DLP tool that nags people over nothing gets ignored, and ignored controls protect no one.
4. Enforce and support
We move to active blocking, train your team on the prompts, and stay on call as your data and staff change.
Which industries lean on Purview DLP most
Any business holding customer data has a reason to care. A few sectors feel the pressure first, because a regulator or a contract demands it.
BFSI and NBFCs
RBI cyber resilience and DPDP both expect tight control over PAN, account and card data. Purview gives a clean audit trail.
Pharma and healthcare
Patient and trial data must not leak by email or USB. DLP rules close those exits without slowing the work.
IT services and BPO
Client contracts often require a named DLP control. Purview lets you prove it in a single report.
Microsoft Purview DLP: common questions
Is Microsoft Purview DLP included in my Microsoft 365 plan?
It depends on your plan. Microsoft 365 E5 includes Purview DLP. Microsoft 365 E3 needs the E5 Compliance add-on for full DLP. Business plans have limited native DLP. We map your exact licence in a free DLP health check.
What does Microsoft Purview DLP protect against?
It stops sensitive data leaving Microsoft 365 by email, Teams chat, SharePoint, OneDrive or Windows endpoints. For India it can detect PAN, Aadhaar, bank account and card numbers, so it maps to DPDP and RBI needs.
How much does Purview DLP setup cost in India?
Policy configuration and tuning starts from around 25,000 rupees, indicative and excluding GST, if Purview is already in your licence. Microsoft licence costs are separate and depend on your agreement. You get an exact quote after the assessment.
Purview DLP or a stand-alone DLP tool?
If you already run Microsoft 365 E5 or E3, Purview is usually the cheaper and faster path. If you have a mixed estate or no Microsoft 365, a stand-alone tool like Secure Data Guard often fits better. We deploy both and advise honestly.
Do you configure and support Purview DLP in India?
Yes. We scope the policies and run them in test mode first. Then we tune out false alarms, switch to enforcement, and support the setup from our Navi Mumbai team.
Switch on the protection you already pay for
200+ Indian businesses trust Sirius Star. Response within 4 working hours. Free DLP health check, no card and no sales call.
P.S. A Mumbai NBFC came to us sure they needed to buy a new DLP product. They were already on Microsoft 365 E5. Purview DLP was sitting there, switched off, fully paid for. We configured it in test mode, tuned it over two weeks, and turned on enforcement. They spent on setup, not on a licence they did not need. The compliance head called it the easiest budget conversation of the year.
