How Does DSPM Safeguard Your Data When You Have CSPM/CNAPP

Many security stacks look impressive at first glance. There is a DLP agent on every endpoint, a CASB or SSE proxy watching SaaS traffic, EDR and SIEM for hosts and logs, and perhaps a handful of identity and access governance tools. Yet when a serious incident is investigated, it often turns out that sensitive data moved through a path nobody was really watching, or that multiple tools saw fragments of the story but never connected them.

‍

The common thread is that most stacks were built around infrastructure, not data. They understand networks, workloads, and log lines, but they don’t share a single, consistent understanding of:

‍

• What your sensitive data is
• Where it actually lives
• Who and what can access it
• How it moves across cloud, SaaS, and AI systems

To move beyond that, security leaders are converging on a data‑first architecture that brings together four capabilities: DSPM (Data Security Posture Management), DLP (Data Loss Prevention), DAG (Data Access Governance), and DDR (Data Detection & Response) in a unified model.

Clarifying the Roles

At the heart of this architecture is DSPM. DSPM is your data‑at‑rest intelligence layer. It continuously discovers data across clouds, SaaS, on‑prem, and AI pipelines, classifies it, and maps its posture; configurations, locations, access paths, and regulatory obligations. Instead of a static inventory, you get a living view of where sensitive data resides and how risky it is.

DLP sits at the edges of the system. Its job is to enforce policy on data in motion and in use: emails leaving the organization, files uploaded to the web, documents synced to endpoints, content copied into SaaS apps, or responses generated by AI tools. DLP decides whether to block, encrypt, quarantine, or simply log based on policies and the context it receives.

‍

DAG bridges the gap between “what” and “who.” It’s responsible for least‑privilege access; understanding which human and machine identities can access which datasets, whether they really need that access, and what toxic combinations exist when sensitive data is exposed to broad groups or powerful service accounts.

‍

DDR closes the loop. It monitors access to and movement of sensitive data in real time, looking for unusual or risky behavior: anomalous downloads, mass exports, unusual cross‑region copies, suspicious AI usage. When something looks wrong, DDR triggers detections, enriches them with data context, and kicks off remediation workflows.

When these four functions work together, you get a stack that doesn’t just warn you about potential issues; it actively reduces your exposure and stops exfiltration in motion.

Why “DSPM vs DLP” Is the Wrong Framing

It’s tempting to think of DSPM and DLP as competing answers to the same problem. In reality, they address different parts of the lifecycle. DSPM shows you what’s at risk and where; DLP controls how that risk can materialize as data moves.

Trying to use DLP as a discovery and classification engine is what leads to the noise and blind spots described in the previous section. Conversely, running DSPM without any enforcement at the edges leaves you with excellent visibility but too little control over where data can go.

‍

DSPM and DAG reduce your attack surface; DLP and DDR reduce your blast radius. DSPM and DAG shrink the pool of exposed data and over‑privileged identities. DLP and DDR watch the edges and intervene when data starts to move in risky ways.

A Unified, Data‑First Reference Architecture

In a data‑first architecture, DSPM sits at the center, connected API‑first into cloud accounts, SaaS platforms, data warehouses, on‑prem file systems, and AI infrastructure. It continuously updates an inventory of data assets, understands which are sensitive or regulated, and applies labels and context that other tools can use.

‍

On top of that, DAG analyzes which users, groups, service principals, and AI agents can access each dataset. Over‑privileged access is identified and remediated, sometimes automatically: by tightening IAM roles, restricting sharing, or revoking legacy permissions. The result is a significant reduction in the number of places where a single identity can cause significant damage.

‍

DLP then reads the labels and access context from DSPM and DAG instead of inferring everything from scratch. Email and endpoint DLP, cloud DLP via SSE/CASB, and even platform‑native solutions like Purview DLP all begin enforcing on the same sensitivity definitions and labels. Policies become more straightforward: “Block Highly Confidential outside the tenant,” “Encrypt PHI sent to external partners,” “Require justification for Customer‑Identifiable data leaving a certain region.”

DDR runs alongside this, monitoring how labeled data actually moves. It can see when a typically quiet user suddenly downloads thousands of PHI records, when a service account starts copying IP into a new data store, or when an AI tool begins interacting with a dataset marked off‑limits. Because DDR is fed by DSPM’s inventory and DAG’s access graph, detections are both higher fidelity and easier to interpret.

‍

From there, integration points into SIEM, SOAR, IAM/CIEM, ITSM, and AI gateways allow you to orchestrate end‑to‑end responses: open tickets, notify owners, roll back risky changes, block certain actions, or update policies.

Where Sentra Fits

Sentra’s product vision aligns directly with this data‑first model. Rather than treating DSPM, DAG, DDR, and DLP intelligence as separate products, Sentra brings them together into a single, cloud‑native data security platform.

‍

That means you get:

‍

• DSPM that discovers and classifies data across cloud, SaaS, on‑prem, and AI
• DAG that maps and rationalizes access to that data
• DDR that monitors sensitive data in motion and detects threats
• Integrations that feed this intelligence into DLP, SSE/CASB, Purview, EDR, and other controls

In other words, Sentra is positioned as the brain of the data‑first stack, giving DLP and the rest of your security stack the insight they need to actually stop exfiltration, not just report on it afterward.

As organizations navigate the complexities of cloud environments and AI adoption, the need for robust data classification has never been more critical. With sensitive data sprawling across IaaS, PaaS, SaaS platforms, and on-premise systems, enterprises require tools that can discover, classify, and govern data at scale while maintaining compliance with evolving regulations. The best data classification tools not only identify where sensitive information resides but also provide context around data movement, access controls, and potential exposure risks. This guide examines the leading solutions available today, helping you understand which platforms deliver the accuracy, automation, and integration capabilities necessary to secure your data estate.

‍

What Are Data Classification Tools?

Data classification tools are specialized platforms designed to automatically discover, categorize, and label sensitive information across an organization's entire data landscape. These solutions scan structured and unstructured data, from databases and file shares to cloud storage and SaaS applications, to identify content such as personally identifiable information (PII), financial records, intellectual property, and regulated data subject to compliance frameworks like GDPR, HIPAA, or CCPA.

‍

Effective data classification tools leverage machine learning algorithms, pattern matching, metadata analysis, and contextual awareness to tag data accurately. Beyond simple discovery, these platforms correlate classification results with access controls, data lineage, and risk indicators, enabling security teams to identify "toxic combinations" where highly sensitive data sits behind overly permissive access settings. This contextual intelligence transforms raw classification data into actionable security insights, helping organizations prevent data breaches, meet compliance obligations, and establish the governance guardrails necessary for secure AI adoption.

Evaluation Criteria for Data Classification Tools

Selecting the right data classification tool requires careful assessment across several critical dimensions:

Classification Accuracy

The engine must reliably distinguish between genuine sensitive data and mock or test data to prevent false positives that create alert fatigue and waste security resources. Advanced solutions employ multiple techniques including pattern matching, proximity analysis, validation algorithms, and exact data matching to improve precision.

Platform Coverage

The best solutions scan IaaS, PaaS, SaaS, and on-premise file shares without moving data from its original location, using metadata collection and in-environment scanning to maintain data sovereignty while delivering centralized governance. This architectural approach proves especially critical for organizations subject to strict data residency requirements.

Automation and Integration

Look for tools that automatically tag and label data based on classification results, integrate with native platform controls (such as Microsoft Purview labels or Snowflake masking policies), and trigger remediation workflows without manual intervention. The depth of integration with your existing technology stack determines how seamlessly classification insights translate into enforceable security policies.

Data Movement Tracking

Modern tools must monitor how sensitive assets flow between regions, migrate across environments (production to development), and feed into AI systems. This dynamic visibility enables security teams to detect risky data transfers before they result in compliance violations or unauthorized exposure.

Scalability and Performance

Evaluate whether the solution can handle your data volume without degrading scan performance or requiring excessive infrastructure resources. Consider the platform's ability to identify toxic combinations, correlating high-sensitivity data with overly permissive access controls to surface the most critical risks requiring immediate remediation.

OpenClaw, previously known as MoltBot, isn't just another cybersecurity story - it's a wake-up call for every organization. With over 150,000 GitHub stars and more than 300,000 users in just two months, OpenClaw’s popularity signals a huge change: autonomous AI agents are spreading quickly and dramatically broadening the attack surface in businesses. This is far beyond the risks of a typical ChatGPT plugin or a staff member pasting data into a chatbot. These agents live on user machines and servers with shell-level access, file system privileges, live memory control, and broad integration abilities, usually outside IT or security’s purview.

‍

Older perimeter and endpoint security tools weren’t built to find or control agents that can learn, store information, and act independently in all kinds of environments. As organizations face this shadow AI risk, the need for real-time, data-level visibility becomes critical. Enter Data Security Posture Management (DSPM): a way for enterprises to understand, monitor, and respond to the unique threats that OpenClaw and its next-generation kin pose.

What makes OpenClaw different - and uniquely dangerous - for security teams?

OpenClaw runs by setting up a local HTTP server and agent gateway on endpoints. It provides shell access, automates browsers, and links with over 50 messaging platforms. But what really sets it apart is how it combines these features with persistent memory. That means agents can remember actions and data far better than any script or bot before. Palo Alto Networks calls this the 'lethal trifecta': direct access to private data, exposure to untrusted content, communication outside the organization, and persistent memory.

‍

This risk isn't hypothetical. OpenClaw’s skill ecosystem functions like an unguarded software supply chain. Any third-party 'skill' a user adds to an agent can run with full privileges, opening doors to vulnerabilities that original developers can’t foresee. While earlier concerns focused on employees leaking information to public chatbots, tools like OpenClaw operate quietly at system level, often without IT noticing.

From theory to reality: OpenClaw exploitation is active and widespread

This threat is already real. OpenClaw’s design has exposed thousands of organizations to actual attacks. For instance, CVE-2026-25253 is a severe remote code execution flaw caused by a WebSocket validation error, with a CVSS score of 8.8. It lets attackers compromise an agent with a single click (critical OpenClaw vulnerability).

‍

Attackers wasted no time. The ClawHavoc malware campaign, for example, spread over 341 malicious 'skills’, using OpenClaw’s official marketplace to push info-stealers and RATs directly into vulnerable environments. Over 21,000 exposed OpenClaw instances have turned up on the public internet, often protected by nothing stronger than a weak password, or no authentication at all. Researchers even found plaintext password storage in the code. The risk is both immediate and persistent.

The shadow AI dimension: why you’re likely exposed

One of the trickiest parts of OpenClaw and MoltBot is how easily they run outside official oversight. Research shows that more than 22% of enterprise customers have found MoltBot operating without IT approval. Agents connect with personal messaging apps, making it easy for employees to use them on devices IT doesn’t manage, creating blind spots in endpoint management.

‍

This reflects a bigger shift: 68% of employees now access free AI tools using personal accounts, and 57% still paste sensitive data into these services. The risks tied to shadow AI keep rising, and so does the cost of breaches: incidents involving unsanctioned AI tools now average $670,000 higher than those without. No wonder experts at Palo Alto, Straiker, Google Cloud, and Intruder strongly advise enterprises to block or at least closely watch OpenClaw deployments.

Why classic security tools are defenseless - and why DSPM is essential

Despite many advances in endpoint, identity, and network defense, these tools fall short against AI agents such as OpenClaw. Agents often run code with system privileges and communicate independently, sometimes over encrypted or unfamiliar channels. This blinds existing security tools to what internal agent 'skills' are doing or what data they touch and process. The attack surface now includes prompt injection through emails and documents, poisoning of agent memory, delayed attacks, and natural language input that bypasses static scans.

‍

The missing link is visibility: understanding what data any AI agent - sanctioned or shadow - can access, process, or send out. Data Security Posture Management (DSPM) responds to this by mapping what data AI agents can reach, tracing sensitive data to and from agents everywhere they run. Newer DSPM features such as real-time risk scoring, shadow AI discovery, and detailed flow tracking help organizations see and control risks from AI agents at the data layer (Sentra DSPM for AI agent security).

Immediate enterprise action plan: detection, mapping, and control

Security teams need to move quickly. Start by scanning for OpenClaw, MoltBot, and other shadow AI agents across endpoints, networks, and SaaS apps. Once you know where agents are, check which sensitive data they can access by using DSPM tools with AI agent awareness, such as those from Sentra (Sentra’s AI asset discovery). Treat unauthorized installations as active security incidents: reset credentials, investigate activity, and prevent agents from running on your systems following expert recommendations.

‍

For long-term defense, add continuous shadow AI tracking to your operations. Let DSPM keep your data inventory current, trace possible leaks, and set the right controls for every workflow involving AI. Sentra gives you a single place to find all agent activity, see your actual AI data exposure, and take fast, business-aware action.

Conclusion

OpenClaw is simply the first sign of what will soon be a string of AI agent-driven security problems for enterprises. As companies use AI more to boost productivity and automate work, the chance of unsanctioned agents acting with growing privileges and integrations will continue to rise. Gartner expects that by 2028, one in four cyber incidents will stem from AI agent misuse - and attacks have already started to appear in the news.

‍

Success with AI is no longer about whether you use agents like OpenClaw; it’s about controlling how far they reach and what they can do. Old-school defenses can’t keep up with how quickly shadow AI spreads. Only data-focused security, with total AI agent discovery, risk mapping, and ongoing monitoring, can provide the clarity and controls needed for this new world. Sentra's DSPM platform offers precisely that. Take the first steps now: identify your shadow AI risks, map out where your data can go, and make AI agent security a top priority.
