What is Data Loss Prevention?
Data Loss Prevention (DLP) is a set of technologies, policies, and processes that detect, monitor, and block unauthorised access, sharing, or transfer of sensitive data — across endpoints, networks, email, cloud storage, and AI tools.
Modern DLP solutions go beyond keyword matching. They use machine learning, behavioural analytics, and data classification to understand context — protecting intellectual property, PII, financial records, and regulated data before a breach occurs.
DLP for Generative AI — The Newest Critical Risk
78% of enterprises now use GenAI tools like ChatGPT and Microsoft Copilot. Employees can inadvertently paste sensitive contracts, customer records, or source code into AI prompts — exposing data outside your organisation's control. NetNXT DLP includes GenAI application controls that monitor and block sensitive data from entering AI workflows in real time.
Comprehensive Data Loss Prevention Capabilities
End-to-end sensitive data protection with automated discovery, classification, policy enforcement, and incident response.
Content Discovery & Classification
Automatically discover and classify sensitive data — PII, PHI, financial records, IP — across endpoints, file servers, and cloud storage using ML-powered data classification with exact data matching and document fingerprinting.
Real-Time Data Monitoring
Monitor data in motion across email, web uploads, messaging, and file transfers with instant alerts and automated blocking — stopping exfiltration attempts before sensitive data leaves your organisation.
DLP Policy Enforcement
Define and enforce granular DLP policies based on user role, data type, destination, and context — automatically blocking, encrypting, or quarantining unauthorised data access, sharing, and transfer.
Encryption Controls
Automatically encrypt sensitive data in transit and at rest based on classification level and security policies — ensuring protected data remains unreadable even if intercepted or accessed without authorisation.
Sensitive Data Classification
ML-powered classification of structured and unstructured data with custom labels, exact data matching (EDM), and fingerprinting — accurately identifying sensitive content regardless of file type or format.
Incident Response & Forensics
Automated workflows and forensic tools for investigating, remediating, and documenting data security incidents — with complete audit trails and evidence packages for compliance reporting and legal review.
How DLP Works: Discover, Classify, Enforce
NetNXT implements DLP in three phases that give your security team full visibility and control over sensitive data at every stage of its lifecycle.
Discover & Map Sensitive Data
Scan all environments to locate sensitive data and understand where it lives and who can access it.
- Endpoint and file server scanning
- Cloud storage discovery (AWS, GDrive, OneDrive)
- SaaS application data inventory
- Structured and unstructured data mapping
Classify & Label
Apply ML-powered classification with custom labels, fingerprinting, and exact data matching.
- PII, PHI, PCI, and IP classification
- Exact data matching (EDM)
- Document fingerprinting
- Aadhaar, passport, and India-specific PII
Enforce, Block & Respond
Apply DLP policies that automatically block, encrypt, or quarantine unauthorised data transfers.
- Real-time policy enforcement
- Automated block, alert, and encrypt actions
- Full audit logs and compliance reports
- Incident investigation workflows
Network, Endpoint, Cloud & Email DLP
Sensitive data doesn't stay in one place. NetNXT DLP protects every channel through which data can leave your organisation — with unified visibility across all vectors.
Network DLP
Deep packet inspection for all network traffic, protocol-aware content analysis, real-time blocking and quarantine, SSL/TLS inspection, and data-in-motion protection across all network layers.
Endpoint DLP
USB and removable device control, clipboard and screen capture monitoring, file operation tracking, offline policy enforcement, and BYOD coverage for remote and hybrid teams.
Cloud DLP
SaaS application protection, cloud storage scanning, API-based controls, multi-cloud support, and GenAI tool monitoring — blocking sensitive data from ChatGPT, Copilot, and Gemini.
Email DLP
Inbound and outbound email scanning, attachment analysis and blocking, automatic encryption of sensitive emails, external sharing controls, and phishing-linked data exfiltration detection.
Insider Threat Prevention
UEBA-powered behavioural analytics detect anomalous data access — bulk downloads, off-hours transfers, uploads to personal accounts — and block suspicious activity before data is exfiltrated.
Third-Party & Vendor Risk
Control data sharing with vendors, partners, and external collaborators — enforcing least-privilege access and monitoring outbound data flows to prevent third-party data exposure.
What Changes When You Deploy Enterprise DLP
Organisations running NetNXT DLP report measurable improvements in data security posture, compliance readiness, and analyst efficiency within weeks.
95% Reduction in Data Breach Incidents
Proactive policy enforcement blocks unauthorised data transfers at every channel — endpoints, email, cloud, and network — before data leaves the organisation. Reduces the blast radius of both accidental and malicious breaches.
Automated Compliance Reporting
Pre-built compliance templates for GDPR, HIPAA, PCI DSS, DPDPA, and ISO 27001 generate audit-ready reports automatically — reducing manual evidence collection effort by over 70% and eliminating last-minute compliance gaps.
Real-Time Insider Threat Detection
UEBA establishes individual user behaviour baselines and flags anomalies — privilege escalation, bulk downloads, off-hours data access — enabling your security team to intervene before sensitive data is exfiltrated.
Unified Visibility Across All Data Flows
A single DLP console provides real-time visibility into data movement across endpoints, networks, email, cloud, and GenAI tools — eliminating blind spots and giving your team a complete picture of your data security posture.
Modern DLP vs Unprotected Environments
See the gap in data security posture between organisations with enterprise DLP in place versus those relying on basic controls and reactive response.
Meet Every Regulatory Requirement
NetNXT DLP comes with pre-built compliance templates, automated reporting, and audit-ready documentation for all major data protection frameworks — including India's DPDPA.
India's Digital Personal Data Protection Act (DPDPA) mandates strict controls over how organisations collect, store, and process personal data. NetNXT DLP helps Indian enterprises achieve DPDPA compliance with automated data discovery, consent-aware access controls, and breach reporting workflows.
What Does DLP Protect?
From financial data to GenAI leakage, NetNXT DLP covers every sensitive data scenario your organisation faces — across industries.
Financial Data Protection
Prevent unauthorised access to credit card numbers, bank account details, and financial records — with PCI DSS-aligned DLP policies and real-time alerts for suspicious data movement across all channels.
Healthcare Privacy & HIPAA
Safeguard patient health information (PHI/ePHI) and ensure HIPAA compliance across all systems, devices, and communication channels used by clinical and administrative teams.
Intellectual Property
Block theft of trade secrets, source code, product designs, and proprietary business information — whether by departing employees, contractors, or external attackers targeting your most valuable assets.
PII & Personal Data
Protect personally identifiable information including Aadhaar numbers, passports, and personal identifiers in line with India's DPDPA and GDPR — with automated discovery and consent-aware access controls.
Insider Threat Prevention
Detect and block malicious or accidental data leaks by employees and contractors using behavioural analytics (UEBA) that flags anomalous data access patterns before damage occurs.
Third-Party & Vendor Risk
Control data sharing with vendors, partners, and external collaborators — enforcing least-privilege access and monitoring outbound data flows to third-party environments and collaboration platforms.
