LeakSignal 360

January 23, 2025

Since the very beginning, we have been focused on the hardest problem within the

data loss prevention (DLP) and data security posture management (DSPM) categories—

classifying data in-transit.

Our journey started by partnering with the industry’s leading vendors, enabling us to deliver enterprise-grade solutions that unify network intelligence and data classification for unmatched data security capabilities. These collaborations and countless real-world deployments provided us with deep insights into the evolving challenges our customers face.  Current solutions fall short as they only sound alarms, overloading security teams without providing the means to enforce policies or demonstrate compliance at the data level. It’s not enough to just point out problems; the future lies in real-time classification, proactive remediation, and AI-driven enforcement to protect data in-transit and beyond.

Introducing LeakSignal 360

Today, we’re excited to unveil LeakSignal 360—the next generation of truly dynamic Data Security Posture Management. Our radically reimagined platform unifies data and network security into one cohesive solution. More than a minor iteration, it’s a reinvention of how to safeguard sensitive information across on-prem, multi-cloud, serverless, and hybrid environments. LeakSignal 360 goes beyond traditional DSPM solutions by combining patented data-at-rest scanning with AI-driven, network-based analysis, and now endpoint-level coverage—delivering truly end-to-end data protection. This comprehensive approach sets a new industry standard for next-gen DLP and DSPM products, ensuring real-time visibility into compliance risks from core infrastructure all the way to employee devices.

What Makes LeakSignal 360 Different?

AI Agents, Not Connectors

Traditional DSPM solutions rely on individual, static connectors for every data store, often resulting in cumbersome integrations and limited adaptability in dynamic cloud-native environments. To revolutionize this approach, we are excited to introduce the first AI Agent for cloud-native proxies, seamlessly deployable as WebAssembly (WASM) or native modules within Envoy and Nginx. This pioneering solution transforms our lightweight Rust-based module into intelligent agents positioned at every insertion point—including proxies, network adapters, microservices, and endpoints—leveraging advanced artificial intelligence to accurately classify sensitive data in real-time.

Inside the AI Agent: A Multi-Stage Content Filtering Pipeline

Our AI agents utilize a layered approach to detect and classify sensitive data in real time:

 

1. Regex-Based Detection

  • Quick pattern-matching identifies common sensitive data formats (e.g., credit card numbers, social security numbers).
  • Ideal for in line filtering and performant identification of important data types.
 

2. Advanced Checksums & State Machine

  • A stateful engine keeps track of data context as it flows, performing checksummed comparisons to detect anomalies or changes in structure.
  • Works in tandem with real-time NLP to parse content for potential policy violations.
 

3. Final Stage Bloom Filters and LLMs

  • Before data crosses a boundary, the agent checks content against ML-driven models (e.g., LLM-based classification) or Bloom filters that are powered by insights from data-at-rest scans.
  • This ensures intelligent, context-aware classification and minimal false positives by comparing real-time data to the patterns discovered during static scans.
 

By combining fast, rule-based detection with deeper AI-driven analysis, our agents enable on-the-fly decisions about whether to block, encrypt, or quarantine data—protecting your environment at every critical juncture. Policy-driven logic adds the crucial oversight layer, turning raw detection outcomes into immediate enforcement actions. For example, if a policy dictates “No unencrypted credit card data may cross this boundary,” the AI agent automatically masks or encrypts that information in real time, ensuring data remains compliant and secure. After each enforcement, outcomes—such as false positives or repeated violations—feed back into the system, allowing the policy engine to refine thresholds and rules continuously. Over time, this feedback loop reduces manual intervention for security teams, strengthens your overall data protection, and ensures continuous alignment with regulations like GDPR, HIPAA, or CCPA.

Real-Time Classification & Enforcement

Whether data is at rest or in transit, our agents classify it in real time, identifying sensitive information and applying appropriate policies before it crosses critical boundaries. This immediate response turns “reactive detection” into proactive defense, blocking potential leaks or compliance breaches on the spot—even if they originate at employee devices.

Endpoint Data Flow Monitoring

One of the most powerful advancements in LeakSignal 360 is its built-in guardrails for employees using third-party LLMs (like ChatGPT). By applying real-time classification and policy checks at the endpoint level, the platform prevents inadvertent oversharing of sensitive information—enabling organizations to harness AI-driven productivity without compromising data security. Beyond traditional cloud or on-prem data stores, LeakSignal 360 continuously monitors data flows on laptops and desktops. Our elegant insertion point integrates at the network or OS layer (not just a browser extension), giving you full visibility into how sensitive data moves while ensuring compliance with internal policies and external regulations.

Unified Network & Data Visibility

LeakSignal 360 provides a complete view that correlates data context with network telemetry. Gone are the days of siloed dashboards and guesswork. You get a single pane of glass that shows not just where your data is but also how it’s being accessed, who is using it, and now even what’s happening at the endpoint level—critical context for both security and compliance teams.

Lessons Learned from Our Customers

A recurring theme from enterprise deployments is that many DSPM solutions simply flag issues—unsecured buckets, misconfigurations, exposed PII—but do little to remediate them. That burden falls heavily on security teams, often leading to manual fixes prone to delays and errors.

“I’ve heard it again and again from our customers: the current DSPM offerings barely differ from one another. They simply scan data at rest, leaving security teams to manually fix potential issues—piece by piece,” explains the CEO of LeakSignal. “With LeakSignal 360, we’re closing that gap—providing both real-time detection and automated remediation that adapt to wherever data moves.”

By embedding micro-agents capable of on-the-fly policy enforcement, we automate much of the remediation process so your environment remains continuously secured. This applies across network gateways, cloud storage, databases, and now employee endpoints, giving you a unified, fully protected ecosystem.

Why This Matters Right Now

Regulatory Pressure Has Intensified

Data privacy regulations like GDPR, HIPAA, and CCPA now extend to AI outputs containing personal data. As generative AI models and automations grow in popularity, organizations must account for the possibility that sensitive information appears in AI-produced content. LeakSignal 360 ensures you can track and enforce compliance across not just conventional data repositories and workloads, but also ephemeral AI pipelines—and even endpoint activities—staying ahead of these emerging requirements.

Evolving Threat Landscape

Attackers don’t wait for scheduled scans. Real-time, in-transit data classification puts you in a defensive position to contain threats immediately, whether it’s an insider threat, a supply chain breach, or a zero-day exploit. And by monitoring endpoints, you address one of the most common threat vectors in modern security breaches.

Data Sprawl and Complexity

Today’s hybrid environments span on-prem data lakes, multi-cloud storage, SaaS apps, microservices, and user endpoints. Our embedded AI agents autonomously discover new data flows and misconfigurations as they happen, significantly reducing the risk of your security posture slipping out of alignment.

Looking Ahead

We’re committed to continuous innovation. Future updates will include advanced behavioral analytics, deeper AI-driven insights for auto-remediation, and expanded support for containerized and serverless architectures. Our mission remains clear: be the definitive platform that aligns network-level intelligence, data-centric security, and endpoint monitoring, giving you a real-time, end-to-end shield against evolving threats and compliance risks.
