// DLP in ECM — 3 threat vectors to govern:
1. Unauthorised internal access (over-permissioned roles, shared credentials)
2. Uncontrolled external sharing (email attachments, open links)
3. Exfiltration without visibility (downloads with no audit trail)

Data loss prevention (DLP) in the context of enterprise document management is the set of controls that prevent sensitive documents from leaving the governed environment without authorisation — whether through accidental sharing, deliberate exfiltration, over-permissioned access, or insecure external collaboration. In 2026, with India's DPDP Act in force and RBI IT Framework requirements tightened, DLP is a compliance requirement, not just a security best practice.

The critical insight for ECM-based DLP is that most document security incidents in Indian enterprises are not sophisticated attacks — they are governance failures. A document emailed to the wrong distribution list. A shared drive link that was never set to expire. A departing employee's access that was not revoked. An overly permissive "view and download" setting applied to an entire folder instead of specific documents. ECM DLP closes these structural gaps.

The DLP Threat Landscape for Indian Enterprises in 2026

Threat Vector	Common Pattern	Regulatory Exposure
Departing employee	Downloads client data or proprietary documents before last day	DPDP Act breach, trade secret exposure
Uncontrolled external sharing	Confidential document emailed to wrong vendor, link never expires	DPDP Act, contractual breach, PII exposure
Over-permissioned access	"View all" on shared drive gives junior staff access to board papers, contracts	RBI IT Framework, ISO 27001 A.9
Shadow copies	Staff save sensitive documents to personal laptops or WhatsApp for convenience	DPDP Act, confidentiality obligations
No audit trail	Incident investigation impossible — no record of who accessed or downloaded what	RBI IT Framework, ISO 27001 A.12.4, DPDP breach reporting

ECM DLP Controls — 6 Layers of Protection

1

Role-Based Access Control (RBAC)

Least-privilege access enforced at document type, folder, and document-state level. HR staff cannot see financial contracts. Finance cannot see legal strategy documents. Access is assigned to roles, not individuals — reducing the risk of over-permissioning when new staff are added.

2

Controlled External Sharing

External sharing via expiring, watermarked links — not email attachments. Every external share is access-tracked. Links can be revoked at any time. Recipients cannot forward access. Sharing is scoped to specific documents, not entire folders.

3

Immutable Audit Trail

Every view, download, edit, share, and deletion attempt is logged with user identity, timestamp, IP, and action. The audit log is tamper-evident — cannot be edited or deleted by any user. Available for incident investigation, regulatory inspection, and ISO 27001 access review evidence.

4

Access Revocation on Offboarding

Single-action access revocation when an employee leaves — all ShareDocs access removed simultaneously, not one folder at a time. Combined with the audit log, the offboarding process generates a complete record of what the departing employee accessed in their final days.

5

Download Restrictions

Sensitive document classifications can have download disabled by default — users can view in-browser but cannot save locally. For highly sensitive documents, view-only access prevents shadow copy creation without preventing legitimate access for review purposes.

6

Encryption at Rest and in Transit

AES-256 encryption at rest, TLS 1.2+ in transit. Documents are unreadable without authenticated platform access — intercept of network traffic or physical access to storage does not expose document content.

DLP and ISO 27001 — The Control Mapping

ShareDocs is ISO 27001 certified. The six DLP controls above map directly to ISO 27001 Annex A domains — meaning that implementing ShareDocs DLP simultaneously satisfies ISO 27001 control requirements for document security:

ShareDocs DLP Control	ISO 27001 Annex A
RBAC + least privilege	A.9.1 Access control policy, A.9.2 User access management
Controlled external sharing	A.13.2 Information transfer, A.15.1 Supplier relationships
Immutable audit trail	A.12.4 Logging and monitoring, A.16.1 Incident management
Access revocation	A.9.2.6 Removal of access rights
Download restrictions	A.8.2 Information classification, A.8.3 Media handling
Encryption	A.10.1 Cryptographic controls, A.13.1 Network security

What We See in Practice

From the Field

A fintech company in Bengaluru discovered — during a routine ISO 27001 access review — that 40% of their current employees had access to at least one document repository they had no business reason to access. This was not malicious configuration; it was the accumulation of temporary access grants ("just for this project") that were never revoked. No data breach had occurred, but the exposure was significant — financial models, term sheets, and investor presentations were accessible to engineers who joined after those documents were created. ShareDocs RBAC and quarterly access review reports — generated directly from the audit log — reduced unauthorised access exposure to under 3% within two review cycles.

For organisations managing governance and compliance programmes, DLP evidence from ShareDocs audit logs satisfies the access monitoring requirements of ISO 27001, RBI IT Framework, and DPDP Act simultaneously. See our Business Continuity solution for document backup and recovery controls that complement DLP.

FAQ

Browser-based screenshot prevention is not technically reliable across all devices and operating systems. ShareDocs' DLP approach focuses on controls that are structurally enforceable: access control, download restrictions, audit logging, and controlled external sharing. Watermarking on sensitive documents (embedding user identity and timestamp in the visible document) acts as a deterrent and attribution mechanism for screenshots — a watermarked screenshot is identifiable back to the user who took it.

Immediately. ShareDocs user deactivation is a single action that simultaneously revokes all platform access — document repositories, workflow queues, and shared links. The deactivation is effective in under 60 seconds. Active sessions are terminated. All previously generated sharing links are also invalidated. The audit log records the deactivation event with timestamp, providing evidence for HR and legal records.
