Cloud DLP solutions, like Strac, provide unparalleled visibility and control into an organization's data while mitigating fraudulent activity.
Data loss can be a nightmare, costing businesses valuable time and money. Losing crucial data means losing countless hours of hard work, critical data, and ultimately client trust. Data breaches are an unfortunate reality of our digital world and are increasingly common.
According to Statista, the average cost of a data breach globally in 2022 was $4.35 million, a 2.6% increase from 2021. Protecting sensitive information has never been more crucial in today's interconnected society.
DLP is the practice of detecting and preventing unauthorized access to sensitive data within and outside a network. DLP security solutions are more than just data storage and retention policies. They help organizations maintain regulatory compliance. DLP solutions promptly respond to breaches or security incidents with alerts, encryption, and data isolation capabilities. DLP software accelerate incident response by identifying threats and anomalous activity during routine monitoring.
Moreover, they ensure compliance with regulations like HIPAA and GDPR. A comprehensive DLP system provides complete insight into all network data, whether in use, motion, or rest.
Data loss prevention has become essential today because data moves faster, lives in more places, and is exposed to more risks than ever before. Organizations no longer operate from a single network perimeter; sensitive information travels through SaaS apps, cloud storage, AI tools, and employee devices. With this constant movement, companies need data loss prevention to maintain visibility; enforce policies; and prevent costly mistakes that can lead to breaches, fines, or reputational damage.
Traditional security tools cannot keep up with the velocity of data in modern work environments. Critical information like PII, PHI, PCI, financial data, and secrets travels through Slack messages, Google Drive files, Salesforce tickets, customer support chats, and GenAI prompts. Even one accidental upload, misconfigured file, or unauthorized access can create exposure that takes months to detect.
Strac solves this by providing real-time data loss prevention across the full data surface; SaaS, Cloud, GenAI, and Endpoints. Strac discovers sensitive data automatically, classifies it with ML and OCR, and applies instant remediation actions like redaction, masking, blocking, and quarantine.
Modern data loss prevention works by continuously inspecting data where it is created, stored, shared, or accessed, then applying policies that prevent unauthorized exposure or misuse. As companies adopt SaaS tools and AI systems at scale, data loss prevention must operate outside the traditional network perimeter and function in real time. Effective DLP today relies on content awareness, automation, and broad coverage to monitor data regardless of location or format.
Modern DLP systems identify sensitive data using ML and OCR; not just regex. They analyze text, attachments, images, PDFs, logs, and even AI prompts or responses. When sensitive elements are detected, the DLP engine enforces security policies like redaction, blocking, encryption, deletion, or alerting.
Strac enhances this with agentless, real-time inspection across tools like Slack, Zendesk, Google Workspace, Salesforce, AWS, and ChatGPT. Every piece of sensitive data triggers immediate remediation; organizations gain visibility, consistent control, and reduced risk across their entire digital ecosystem.
Data Loss Prevention operates through a sophisticated system of monitoring, detection, and enforcement mechanisms. The process begins with data discovery and classification, where the DLP solution scans and categorizes sensitive information across the organization’s network, devices, and cloud storage.
This includes scanning both structured and unstructured data, from databases to documents and emails.
The system employs advanced pattern recognition and machine learning algorithms to identify sensitive data types such as CC numbers, social security numbers, & proprietary information. Once identified, the DLP solution applies predefined policies and rules to control how this data can be used, shared, or transmitted.

The DLP system continuously monitors all data movements, whether the data is:

Your company can readily detect breaches and protect sensitive data if it has a complete picture of the data movement throughout the cycle. You can establish a compliant data policy that guarantees the safety of critical information using DLP'S data categorization.
DLP systems can identify and prevent unauthorized activity on your network thanks to their sophisticated scanning abilities. DLP guarantees that sensitive information stays protected inside the bounds of your network, whether it is sent by email, copied to external devices, or any other means.
Automatic classification is a process that collects important details about a document, such as its creation date, storage location, and sharing methods. This information is used to enhance the accuracy and effectiveness of data classification within your organization. A DLP solution utilizes this information to effectively implement your DLP policy, thereby reducing the risk of unauthorized sharing of sensitive data.
Complying with data protection regulations such as HIPAA, the Sarbanes-Oxley Act (SOX), and the Federal Information Security Management Act (FISMA) is critical. Adopting a DLP solution gives you access to extensive reporting features that simplify compliance audits, reducing noncompliance risks and penalties.
DLP solutions are designed to monitor data access and usage to mitigate threats effectively. It ensures that only those with permission can access sensitive information and keeps track of their activities.
DLP mitigates the risks associated with insider breaches and fraudulent activities by effectively managing the digital identities of employees, vendors, and partners within the network. Role-based access control (RBAC) is one approach that guarantees only authorized users have access to sensitive information.
DLP solutions provide unparalleled visibility into your organization's critical data while identifying fraudulent activity. As organizations transition to cloud computing, maintaining visibility over sensitive information becomes challenging, demanding a cloud DLP solution.
Strac, a cloud DLP solution, automatically detects and redacts (masks) sensitive data (images, text, audio, video) from all Cloud and SaaS apps (email, slack, zendesk, intercom, AWS services, Google Drive, One Drive, ChatGPT, and more).

When it comes to protecting data within an organization, DLP security solutions shine due to their ability to classify and constantly monitor critical data. They dramatically boost your data security by identifying and blocking suspicious and illegal activity.
Various DLP strategies are employed to protect data at different stages and locations within an organization:
Given the complexity of the threat environment and the magnitude of business networks, implementing a Data Loss Prevention (DLP) strategy is no easy feat.
Below best practices can help you maximize your investment in DLP tools .
Prioritize the data you need to protect. Understand the different categories of data in your organization like PII (Personally identifiable information), PHI(Protected Health Information), PCI( Payment Card Industry )data and classify them based on their sensitivity levels. An accurate data inventory is the foundation for effective data loss prevention.
Develop clear DLP policies and procedures based on the type of data you have, its sensitivity, and applicable compliance regulations. This includes identifying who has access to what data, under what circumstances data can be transferred or shared, and what to do in case of a potential breach.
Restrict access to sensitive data and implement the principle of least privilege, granting employees access to only the information necessary for their role. This reduces the risk of data exposure from the inside.
Always encrypt sensitive data both in transit and at rest. In the event of a breach, encryption can render the data useless to unauthorized individuals.
Use your DLP solution to continuously monitor and log all data movements within your network. Regular audits of these logs can help identify potential threats before they cause damage.
Conduct regular DLP training and make sure all employees understand the importance of data security. Often, data breaches are the result of ignorance rather than malicious intent.
Regular testing and updating of your DLP system can help you keep up with evolving security threats. It also helps to ensure that your DLP system remains compatible with other systems in your IT infrastructure.
Have a well-defined incident response plan in place. In the event of a data breach, your team should know exactly what steps to take. This includes how to isolate affected systems, how to investigate the breach, how to communicate the breach to stakeholders and authorities, and how to prevent similar breaches in the future.

Data loss prevention is no longer optional; it is essential for any organization that stores, shares, or builds products with sensitive data. As information spreads across SaaS tools, cloud platforms, endpoints, and GenAI systems, companies need modern data loss prevention that provides visibility, real-time protection, and consistent enforcement. Strac delivers this with agentless deployment, ML and OCR-driven classification, and instant remediation across every critical data surface; helping security teams reduce risk, maintain compliance, and operate with confidence.
A Data Loss Prevention solution monitors, detects, and stops sensitive data from being exposed, misused, or leaving the organization without authorization. Because modern companies use dozens of SaaS apps and cloud systems, data constantly moves; DLP ensures visibility and control at every stage of that movement. A strong DLP also reduces compliance risk by preventing PII, PHI, PCI, secrets, and financial information from leaking into places they should not be.
A DLP solution typically performs three core functions; discover, classify, and protect. It inspects text, attachments, and files; applies sensitivity labels; and enforces real-time policies like blocking, redaction, masking, alerting, or quarantine. With Strac, these protections happen instantly across SaaS, Cloud, GenAI, and Endpoints, giving organizations continuous risk reduction.
The DLP process is a structured workflow that ensures data is identified, labeled, monitored, and protected everywhere it moves. Because companies handle thousands of files, messages, emails, and SaaS interactions daily, this process must be automated and continuous. Modern DLP relies on content-aware detection rather than static rules to keep up with real-world complexity.
The DLP process includes:
• Discovery; scanning data across SaaS apps, cloud storage, endpoints, and AI systems
• Classification; labeling sensitive data using ML, OCR, and policy templates
• Monitoring; tracking where data goes, who accesses it, and how it is used
• Protection; applying real-time remediation actions like redaction, masking, blocking, or quarantine
A complete DLP process ensures that sensitive data is always visible, properly labeled, and automatically protected at scale.
Organizations categorize DLP into three main types because each focuses on a different layer of technology and user behavior. Sensitive data does not live in one place, so effective protection requires coverage across storage, movement, and usage. These three types form the foundation of any complete DLP strategy.
The three core types of DLP are:
• Storage DLP; protects data at rest in databases, cloud storage, local devices, and repositories
• Network DLP; monitors data in motion across internal networks and outbound traffic
• Endpoint DLP; protects data in use on employee devices like laptops, desktops, and local apps
Strac expands this model with SaaS DLP, Cloud DLP, and GenAI DLP, giving companies full coverage across all modern data surfaces.
The best way to prevent data loss is to combine continuous discovery, intelligent classification, and real-time remediation across every platform where data lives. Because threats often come from accidental sharing, misconfiguration, or human error, prevention must be proactive and automated; not reactive. A modern DLP strategy should also integrate with SaaS apps, cloud storage, endpoints, and AI tools to eliminate blind spots.
Highly effective data loss prevention includes:
• Automated scanning across SaaS, Cloud, GenAI, and Endpoints
• ML and OCR-based classification that avoids false positives
• Real-time actions like redaction, masking, blocking, or quarantine
• Continuous monitoring for risky access, sharing, or downloads
• Unified visibility that ties every policy to consistent enforcement
Strac delivers all of these capabilities in one agentless platform; enabling organizations to prevent data loss without slowing down productivity.
