Data Loss Prevention
(DLP) Services

Data Loss Prevention (DLP) is a set of technologies and policies that help organisations identify sensitive information, understand where it is stored and how it moves, and control how it is shared. A DLP programme typically covers data discovery, data classification, policy definition, monitoring of data movement and a defined response when a policy is violated. It applies across endpoints, email, cloud applications, networks and storage.

Most security controls focus on keeping attackers out. DLP focuses on the information itself, which can leave an organisation through everyday activity such as email, file sharing, cloud uploads, removable media or over-broad access. DLP gives security teams visibility into where sensitive data lives and how it is handled, and provides a policy framework to reduce accidental and unauthorized exposure alongside existing controls.

DLP is typically applied to customer and employee personal data, financial records, payment and account information, health records, identity documents, contracts and legal files, intellectual property such as source code and design files, pricing and commercial data, and internal strategic documents. The exact scope is defined during data discovery and classification, based on business and regulatory requirements.

Yes. Modern DLP is deployed across multiple channels: endpoint DLP covers copying, transferring, printing and removable media on managed devices; email DLP inspects outbound messages and attachments; cloud and SaaS DLP applies policies to sanctioned cloud storage and collaboration platforms; and network DLP monitors sensitive information moving across approved network channels. Coverage depends on the platforms in scope and the controls each supports.

Data at rest is stored information in file servers, databases, endpoints, backups and cloud storage. Data in motion is information moving across email, network transfers, cloud sharing and file transfers. Data in use is information actively being handled on an endpoint or in an application, such as copying, pasting, printing or transferring to removable media. A complete DLP strategy addresses all three states rather than only scanning stored files.

DLP platforms identify sensitive information using techniques such as pattern and keyword matching, regular expressions for structured identifiers, document fingerprinting, file type and metadata inspection, classification labels applied by users or systems, and contextual signals including user, application, destination and channel. Analytics can help refine matching over time and reduce false positives. Available techniques vary by platform.

Depending on the configured policy and the capabilities of the technology in use, actions may include alerting, logging, blocking, quarantining, encrypting, prompting the user for justification or requiring additional review. Most organisations begin in monitoring mode to understand normal data handling, then progressively enable stricter enforcement for the highest-risk data and channels.

Cylentrix helps enterprises define the scope of sensitive data, run discovery across approved environments, build a practical classification model, design policies for endpoints, email, cloud and network channels, deploy and tune the selected DLP technology, and integrate data protection events into existing security monitoring. Engagements are phased, starting with visibility and moving toward enforcement as policies mature.
