One Email DLP rule set. Every outgoing message checked before it sends.
How Secure Data Guard put a quiet check between a Vashi logistics team and the send button, so the careless email never reaches a stranger. Story below.
Email DLP at a glance
Why email is still the leak Indian businesses miss first.
- What it is
- A rule engine that sits inside your mail flow and checks every outgoing message in a fraction of a second, before it reaches the recipient.
- Why teams pick it
- Most data loss in India is not a hack. It is a tired person, a busy inbox, and autocomplete picking the wrong contact. Antivirus and firewalls do not catch this — the message leaves through a tool you trust, sent by a person you hired.
- What it checks
- Aadhaar numbers, PAN, bank account and card numbers, salary sheets, and customer databases attached as a spreadsheet. A soft rule warns the sender, a hard rule blocks the message, a third option encrypts the mail.
- Platforms covered
- Microsoft 365 (Exchange Online) and Google Workspace, on the same rule set and the same proof.
- India pricing
- Rs 150 per mailbox per month (Starter, up to 50 mailboxes), down to Rs 90/mailbox at Enterprise scale. Excludes GST, assumes an annual term.
- Sirius Star role
- We tune the rules to Indian data patterns, run a monitor-mode week before any enforcement, train your managers, and stay on call from Navi Mumbai.

Secure Data Guard vs the alternatives you are weighing
All of these are honest tools. The gap is rarely the software — it is the setup and the discipline to keep it running.
| Option | Where it wins | Best fit |
|---|---|---|
| GTB / Safetica | Deep, specialist DLP policy engines. | Large security teams who want to own the rule-writing themselves. |
| Bitdefender / Sophos | DLP folded into a wider endpoint security suite. | Teams already standardised on one of these suites for antivirus. |
| Microsoft Purview | Native to Microsoft 365, no extra licence. | Teams who want a base layer switched on, with Sirius Star tuning it. |
| Secure Data Guard (Sirius Star) | A named consultant in Navi Mumbai who writes the Indian-data rules, trains your managers, and stays on call. | Businesses who want the tool run for them, not just sold to them. |

Email DLP India FAQ
Common questions Indian buyers ask us.
Will it slow down or block normal work?
No. We run a week in monitor mode first, then enforce only the high risk rules. Routine mail flows as usual and staff barely notice it.
Does email DLP work with Google Workspace as well as Microsoft 365?
Yes. Secure Data Guard sets up email DLP on both platforms, with the same rules and the same proof either way.
How fast can email DLP go live?
Most firms reach monitor mode within a few days and full enforcement inside three weeks. There is no hardware to buy.
What proof do we get for a DPDP review?
A written policy, the live rule set, and a log of every blocked or warned email that you can hand to an auditor.
Do you only sell the licence or do you run it?
We run it. A named consultant owns your rules, reviews the alerts, and adjusts as your team grows.
