Data Security

Amidst the dynamic cybersecurity landscape, the need for advanced Threat Detection and Incident Response (TDIR) solutions has never been more crucial. Traditional tools often focus on addressing the complexities of security without data awareness. This deficiency can result in signal fatigue, and increased time to investigate.

Data Detection and Response (DDR) distinguishes itself by focusing on data-first threats, such as: compromise or manipulation of sensitive databases, unauthorized disclosure of sensitive information, intellectual property theft, and many other malicious activities targeting sensitive information. Finally, the obligation to inform and potentially compensate affected parties in compliance with regulatory requirements strengthens the need to enrich TDIR with a data-focused technology.

In this blog, we will start by explaining the difference between data detection and response (DDR) and cloud detection and response (CDR), and how data detection and response (DDR) fits into a cloud data security platform. We will then decode the distinctions between DDR and other TDIR solutions like Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR). Lastly, we will explore why Sentra, with its DDR approach, emerges as a comprehensive and efficient data security solution.

Challenges in Traditional Approaches

Classifying data accurately poses a significant challenge to most traditional cybersecurity approaches. Behavioral analysis, while effective, often overlooks the critical aspect of data type, leading to potential blind spots and excessive false positives. Real-time prevention measures also face limitations, such as they can only protect the platforms they have visibility into, often restricting them to known and managed infrastructure, leaving organizations vulnerable to sophisticated cyber threats that target the public cloud.

Differences Between Data Detection and Response (DDR) and Cloud Detection and Response (CDR)

Cloud detection and response (CDR) solutions focus on overseeing and safeguarding cloud infrastructure, while data detection and response (DDR) specialize in the surveillance and protection of data. DDR plays a crucial role in identifying potential threats to sensitive data, irrespective of its location or format, providing an essential layer of security that goes beyond the capabilities of solutions focusing solely on infrastructure. Additionally, DDR empowers organizations to concentrate on detecting and addressing potential risks to their most sensitive data, reducing noise, cutting costs, and preventing alert fatigue.

When incorporating DDR into a cloud data security platform, organizations should see it as a crucial part of a strategy that encompasses technologies like data security posture management (DSPM), data access governance, and compliance management. This integration enables comprehensive security measures throughout the data lifecycle, enhancing overall cloud data security.

Why do I need a DDR if I’m already using a CDR product?

Data Detection and Response (DDR) is focused on monitoring data access activities that are performed by users and applications, while CDR is focused on infrastructure resources, such as their creation and configuration changes. DDR and CDR serve as detection and response tools, yet they offer distinct sets of threat detection capabilities essential for organizations aiming to prevent cloud data breaches and ransomware attacks.

Some examples where DDR can identify data-centric threats that might go unnoticed by CDR:

  1. Users who download sensitive data types that they don’t usually access.
  2. A ransomware attack in which amounts of business-critical data is being encrypted or deleted.
  3. Users or applications who gain access to sensitive data via a privilege escalation. 
  4. Tampering or poisoning of a Large Language Model (LLM) training dataset by a 3rd party application.
  5. Supply chain attack detection when a compromised third party app is exfiltrating sensitive data from your cloud environment.
  6. Credentials extraction of high-impact keys that have access to sensitive data.

Lastly, DDR offers security operations center (SOC) teams to focus on what matters the most – attacks on their sensitive data, hence reducing the noise and saving time. While CDR detects threats such as impossible travel or brute force log-in attempts on any cloud resources, DDR detects such threats only when the target cloud resources contain sensitive data.

Threat Detection and Incident Response (TDIR) Solutions

Endpoint Detection and Response (EDR)

In the ever-evolving landscape of cybersecurity, Endpoint Detection and Response (EDR) plays a pivotal role in safeguarding the digital perimeters of organizations. Focused on monitoring and responding to suspicious activities at the endpoint level, EDR solutions are crucial for identifying and neutralizing threats before they escalate. Armed with advanced analytics and machine learning algorithms, EDR empowers technical teams to detect anomalous behavior, conduct thorough investigations, and orchestrate rapid responses to potential security incidents.

Extended Detection and Response (XDR)

Extended Detection and Response (XDR) is a solution designed to fortify organizations against sophisticated threats and extend protection beyond EDR. XDR seamlessly integrates threat intelligence, endpoint detection, and incident response across multiple security layers, offering a unified defense strategy. By aggregating and correlating data from various sources such as servers, applications, and other infrastructure, XDR provides unparalleled visibility into potential threats, enabling rapid detection and response. Its proactive approach enhances incident investigation and remediation, ultimately minimizing the impact of cyber threats across an organization's IT estate.

Enter DDR: Revolutionizing Data Security

Data Detection and Response (DDR) brings real-time threat detection to complement data posture controls, hence combining with Data Security Posture Management (DSPM) to address these longstanding challenges. Sentra, a leading player in this domain, ensures real-time data protection across various cloud environments, offering a comprehensive solution to safeguard data wherever it resides. DDR provides a layer of real-time threat detection that is agnostic to infrastructure and works well in multi-cloud environments - it works no matter where data travels.

DDR provides rich near real-time context to complement DSPM. Sentra’s DDR is not dependent on scanning your data. Instead, it continually monitors log activity (ex. AWS CloudTrail events) and can alert on any suspicious or unusual activity such as an exfiltration or unusual access - this can be from a malicious insider or outsider or simply unintended actions from an authorized user or a supply chain partner. Combined with DSPM, DDR provides enhanced context regarding data usage and related exposure. Sentra can help an organization to focus monitoring efforts on areas of greatest risk and reduce the ‘noise’ (false positives or inactionable alarms) from less contextually aware activity monitors.

Proactive and Reactive Data Security with Sentra's DSPM and DDR

Sentra takes a dual-pronged approach, combining proactive and reactive controls to fortify data security at every stage of a potential cyberattack:

  • Weakening Defenses Detection: Continuously monitor for unauthorized changes to data security posture, identifying escalated access privileges or changes in encryption levels.
  • Suspicious Access Detection: Instant alerts are triggered when a third party or insider accesses sensitive information, enabling swift action to prevent potential malicious activities.
  • Reconnaissance: Detect an early stage of the attack when an attacker moves sensitive data across and within cloud networks in order to prepare for the data exfiltration stage.
  • Data Loss and Ransomware Prevention: Real-time monitoring and alerts for accidental or unauthorized data movement, coupled with the enforcement of least privilege data access, prevent potential breaches.
  • Data Exfiltration Detection: Sentra detects anomalous sensitive data movement in near real-time, providing quick notification and remediation before significant damages occur.
  • Breach Recovery Acceleration: In the unfortunate event of a breach, Sentra provides guidance and contextual information, streamlining post-incident analysis and remediation.

Seamless Integration for Enhanced Efficiency

Sentra provides seamless integration into your security workflow. With over 20 pre-built or custom integrations, Sentra ensures that alert context is directly fed to the appropriate teams, expediting issue resolution. This integrated approach enables organizations to respond to potential threats with unmatched speed and efficiency.

Attribute EDR XDR CDR DDR
Monitored environment Endpoints (laptops, desktops, servers, mobile devices) Multiple security layers (endpoints, networks, cloud, email, etc.) Cloud assets and infrastructure Data repositories within the cloud environment
Threat detection method Behavior-based, signature-based, machine learning Correlation of data from multiple sources, machine learning, AI Log analysis, anomaly detection, machine learning Data-aware detection rules and behavioral analysis based on data access
Presence requirement Agent installed on endpoints Integration with multiple security tools Typically agentless, can have agents on cloud resources Typically agentless, Data collection from various sources, not limited to endpoint
Example Vendor CrowdStrike, SentinelOne, Microsoft Defender for Endpoint Trend Micro Vision One, Palo Alto Networks Cortex XDR, Cisco SecureX Wiz, Rapid7 InsightIDR, FireEye Helix Sentra DDR, Exabeam, Securonix, LogRhythm


Data Detection and Response (DDR) is not a replacement or superior solution, it is complementary to the others.

Companies need these technologies for different reasons:

  • EDR for endpoint
  • XDR for on premise
  • CDR for cloud infrastructure
  • DDR for cloud data stores
sensitive data that was accessed from suspicious IP address

With Sentra, organizations get the best of both worlds – proactive and reactive controls integrated for complete data protection. Sentra combines DDR with powerful Data Security Posture Management (DSPM), allowing users to detect and remediate data security risks efficiently.

Data Security in 2025: Why DSPM Is Now a Business Imperative

Data Security in 2025: Why DSPM Is Now a Business Imperative

At RSAC 2025, I had the opportunity to speak with Adrian Sanabria about one of the most pressing and complex challenges facing security teams today: data security. Since then, the urgency around the future of data security has only intensified.

We're watching a major inflection point unfold across industries. Organizations are generating and storing more data than ever, while simultaneously adopting AI at a pace that outstrips most security programs. At the same time, regulators are enforcing data privacy with increasing sharpness. These trends all converge on one critical question:

 

Do you know where your sensitive data is - and who can access it?

If the answer is no, then it's time to rethink your approach.

Data is Now The Most Valuable, And Volatile Asset

For years, security tools have operated largely without visibility into the data itself. We've focused on endpoints, perimeters, and identities - all essential layers. But in 2025, that’s no longer sufficient.

Data is now the most valuable, and volatile asset most companies have. We’re seeing this in breach investigations, where the root cause often traces back to unmonitored or duplicated sensitive data left in the wrong place. We're seeing it in AI deployments, where teams rush to fine-tune models or deploy copilots without knowing what's inside the datasets they’re exposing. And we’re certainly seeing it in regulatory fines, many of which stem from nothing more than storing customer data longer than necessary, in the wrong place, or in unsecured formats.

What all of this underscores is a simple truth: you can’t protect what you can’t see.

The Role of DSPM in the Future of Data Security

At Sentra, we’ve built our platform around a core philosophy that Data Security Posture Management (DSPM) is not just a security tool, it’s the future of data security, an enabler of responsible innovation. The foundation starts with sensitive data discovery. Most organizations are surprised by how much sensitive data exists outside expected systems- in backups, temporary stores, or SaaS apps that were never properly offboarded. From there, classification adds context. It’s not enough to label something as “PII”, we need to understand how sensitive it is, who owns it, how it is being used, and how it should be governed.

We built Sentra as a cloud-native solution from day one. That means it works across IaaS, SaaS, PaaS, and even on-prem environments without needing agents or pulling data outside the customer’s environment. That last point is non-negotiable for us. As a security company, we believe strongly that extracting customer data for analysis creates unnecessary risk and liability.

To support classification at scale, especially for unstructured data, we developed our own language models using open-source LLMs. This provides the deep contextual understanding needed to accurately label large volumes of data all while maintaining cost efficiency and avoiding unnecessary compute overhead.

AI, Risk, and Responsibility in Data Securityy

One of the biggest shifts we’re seeing in the market is how AI has elevated data security from a technical concern to a boardroom issue. Security teams are now being asked to approve large-scale data usage for AI training, RAG systems, copilots, and internal assistants. But very few have the tools to answer basic questions about what’s in those datasets.

I’ve worked with customers who only realized after deploying AI that they had been exposing medical records, credentials, or confidential meeting data to the model. Once it’s in, you can’t pull it back. That’s why data classification and risk detection must come before any AI integration.

This is precisely the use case we had in mind when we built Sentra’s Data Security for AI Module. It helps teams scan, assess, and verify the contents of data before it ever touches a model. The goal isn’t to slow down innovation - it’s to make it safer, auditable, and repeatable.

Proactive Risk Management Helps Enterprises Ship Faster

One of the most exciting developments we’ve seen for the future of data security is how quickly Sentra’s data security platform becomes a strategic asset for enterprise data risk management. Time to value is fast in many cases, our customers discover major data risks just days after deployment. But beyond those early wins, the real power lies in alignment.

When security leaders can map data to risk, compliance, and governance frameworks, and do so continuously, they’re no longer operating reactively. They’re enabling the business, helping teams ship faster with fewer unknowns, and building trust around how AI and data are managed.

At scale, this kind of maturity is the difference between organizations that can confidently embrace generative AI and those that will always be playing catch-up.

A Final Word

From my time in the Israeli Defense Forces and Unit 8200 to helping enterprises build modern security programs, I’ve seen one truth over and over again: data left behind is data exposed. The volume may grow, the threats may change, but this principle doesn’t.

In 2025, securing data is no longer an aspiration, it’s a baseline. Whether you’re preparing for your next AI initiative, facing regulatory audits, or just trying to get visibility into sprawling cloud environments, DSPM should be your first step. At Sentra, we’re proud to help lead this change. And we believe the organizations that take control of their data today will be the ones best positioned to lead tomorrow.

Data Blindness: The Hidden Threat Lurking in Your Cloud

Data Blindness: The Hidden Threat Lurking in Your Cloud

“If you don’t know where your sensitive data is, how can you protect it?”

It’s a simple question, but for many security and compliance teams, it’s nearly impossible to answer. When a Fortune 500 company recently paid millions in fines due to improperly stored customer data on an unmanaged cloud bucket, the real failure wasn’t just a misconfiguration. It was a lack of visibility.

Some in the industry are starting to refer to this challenge as "data blindness".

What Is Data Blindness?

Data Blindness refers to an organization’s inability to fully see, classify, and understand the sensitive data spread across its cloud, SaaS, and hybrid environments.

It’s not just another security buzzword. It’s the modern evolution of a very real problem: traditional data protection methods weren’t built for the dynamic, decentralized, and multi-cloud world we now operate in. Legacy DLP tools or one-time audits simply can’t keep up.

Unlike general data security issues, Data Blindness speaks to a specific kind of operational gap: you can’t protect what you can’t see, and most teams today are flying partially blind.

Why Data Blindness Is Getting Worse

What used to be a manageable gap in visibility has now escalated into a full-scale operational risk. As organizations accelerate cloud adoption and embrace SaaS-first architectures, the complexity of managing sensitive data has exploded. Information no longer lives in a few centralized systems, it’s scattered across AWS, Azure, and GCP instances, and a growing stack of SaaS tools, each with its own storage model, access controls, and risk profile.

At the same time, shadow data is proliferating. Sensitive information ends up in collaboration platforms, forgotten test environments, and unsanctioned apps - places that rarely make it into formal security inventories. And with the rise of generative AI tools, a new wave of unstructured content is being created and shared at scale, often without proper visibility or retention controls in place.

To make matters worse, many organizations are still operating with outdated identity and access frameworks. Stale permissions and misconfigured policies allow unnecessary access to critical data, dramatically increasing the potential impact of both internal mistakes and external breaches.

In short, the cloud hasn’t just moved the data, it’s multiplied it, fragmented it, and made it harder than ever to track. Without continuous, intelligent visibility, data blindness becomes the default.

The Hidden Risks of Operating Blind

When teams don’t have visibility into where sensitive data lives or how it moves, the consequences stack up quickly:

  • Compliance gaps: Regulations like GDPR, HIPAA, and PCI-DSS demand accurate data inventories, privacy adherence, and prompt response to DSARs. Without visibility, you risk fines and legal exposure.

  • Breach potential: Blind spots become attack vectors. Misplaced data, overexposed buckets, or forgotten environments are easy targets.

  • Wasted resources: Scanning everything (just in case) is expensive. Without prioritization, teams waste cycles on low-risk data.

  • Trust erosion: Customers expect you to know where their data is and how it’s protected. Data blindness isn’t a good look.

Do You Have Data Blindness? Here Are the Signs

  • Your security team can’t confidently answer, “Where is our most sensitive data and who has access to it?”

  • Data inventories are outdated, or built on manual tagging and spreadsheets.

  • You’re still relying on legacy DLP tools with poor context and high false positives.

  • Incident response is slow because it’s unclear what data was touched or how sensitive it was.

Sound familiar? You’re not alone.

Breaking Free from Data Blindness

Solving data blindness starts with visibility, but real progress comes from turning that visibility into action. Modern organizations need more than one-off audits or static reports. They need continuous data discovery that scans cloud, SaaS, and on-prem environments in real time, keeping up with the constant movement of data.

But discovery alone isn’t enough. Classification must go beyond content analysis, it needs to be context-aware, taking into account where the data lives, who has access to it, how it’s used, and why it matters to the business. Visibility must extend to both structured and unstructured data, since sensitive information often hides in documents, PDFs, chat logs, and spreadsheets. And finally, insights need to be integrated into existing security and compliance workflows. Detection without action is just noise.

How Sentra Solves Data Blindness

At Sentra, we give security and privacy teams the visibility and context they need to take control of their data - without disrupting operations or moving it out of place. Our cloud-native DSPM (Data Security Posture Management) platform scans and classifies data in-place across cloud, SaaS, and on-prem environments, with no agents or data removal required.

Sentra uses AI-powered, context-rich classification to achieve over 95% accuracy, helping teams identify truly sensitive data and prioritize what matters most. We provide full coverage of structured and unstructured sources, along with real-time insights into risk exposure, access patterns, and regulatory posture, all with a cost-efficient scanning model that avoids unnecessary compute usage.

One customer reduced their shadow data footprint by 30% in just a few weeks, eliminating blind spots that their legacy tools had missed for years. That’s the power of visibility, backed by context, at scale.

The Bottom Line: Awareness Is Step One

Data Blindness is real, but it’s also solvable. The first step is acknowledging the problem. The next is choosing a solution that brings your data out of the dark, without slowing down your teams or compromising security.

If you’re ready to assess your current exposure or just want to see what’s possible with modern data security, you can take a free data blindness assessment, or talk to our experts to get started.

Why Sentra Was Named Gartner Peer Insights Customer Choice 2025

Why Sentra Was Named Gartner Peer Insights Customer Choice 2025

When we started Sentra three years ago, we had a hypothesis: organizations were drowning in data they couldn't see, classify, or protect. What we didn't anticipate was how brutally honest our customers would be about what actually works, and what doesn't.

This week, Gartner named Sentra a "Customer's Choice" in their Peer Insights Voice of the Customer report for Data Security Posture Management. The recognition is based on over 650 verified customer reviews, giving us a 4.9/5 rating with 98% willing to recommend us.

The Accuracy Obsession Was Right

The most consistent theme across hundreds of reviews? Accuracy matters more than anything else.

"97.4% of Sentra's alerts in our testing were accurate! By far the highest percentage of any of the DSPM platforms that we tested."

"Sentra accurately identified 99% of PII and PCI in our cloud environments with minimal false positives during the POC."

But customers don't just want data discovery—they want trustworthy data discovery. When your DSPM tool incorrectly flags non-sensitive data as critical, teams waste time investigating false leads. When it misses actual sensitive data, you face compliance gaps and real risk. The reviews validate what we suspected: if security teams can't trust your classifications, the tool becomes shelf-ware. Precision isn't a nice-to-have—it's everything.

How Sentra Delivers Time-to-Value

Another revelation: customers don't just want fast deployment, they want fast insights.

"Within less than a week we were getting results, seeing where our sensitive data had been moved to."

"We were able to start seeing actionable insights within hours."

I used to think "time-to-value" was a marketing term. But when you're a CISO trying to demonstrate ROI to your board, or a compliance officer facing an audit deadline, every day matters. Speed isn’t a luxury in security, it’s a necessity. Data breaches don't wait for your security tools to finish their months-long deployment cycles. Compliance deadlines don't care about your proof-of-concept timeline. Security teams need to move at the speed of business risk.

The Honesty That Stings (And Helps)

But here's what really struck me: our customers were refreshingly honest about our shortcomings.

"The chatbot is more annoying than helpful."

"Currently there is no SaaS support for something like Salesforce."

"It's a startup so it has all the advantages and disadvantages that those come with."

As a founder, reading these critiques was... uncomfortable. But it's also incredibly valuable. Our customers aren't just users, they're partners in our product evolution. They're telling us exactly where to invest our engineering resources.

The Salesforce integration requests, for instance, showed up in nearly every "dislike" section. Message received. We're shipping SaaS connectors specifically because it’s a top priority for our customers.

What Gartner Customer Choice Trends Reveal About the DSPM Market

Analyzing 650 reviews across 9 vendors revealed something fascinating about our market's maturity. Customers aren't just comparing features, they're comparing outcomes.

The traditional data security playbook focused on coverage: "How many data sources can you scan?" But customers are asking different questions:

  • How accurate are your findings?
  • How quickly can I act on your insights?
  • How much manual work does this actually eliminate?

This shift from inputs to outcomes suggests the DSPM market is maturing rapidly. 

The Gartner Voice of the Customer Validated

Perhaps the most meaningful insight came from what customers didn't say. I expected more complaints about deployment complexity, integration challenges, or learning curves. Instead, review after review mentioned how quickly teams became productive with Sentra.

"It was also the fastest set up."

"Quick setup and responsive support."

"The platform is intuitive and offers immediate insights."

This tells me we're solving a real problem in a way that feels natural to security teams. The best products don't just work, they feel inevitable once you use them.

The Road Ahead: Learning from Gartner Choice Recognition

These reviews crystallized our 2025 roadmap priorities:

1. SaaS-First Expansion: Every customer asked for broader SaaS coverage. We're expanding beyond IaaS to support the applications where your most sensitive data actually lives. Our mission is to secure data everywhere.

2. AI Enhancement: Our classification engine is industry-leading, but customers want more. We're building contextual AI that doesn't just find data, it understands data relationships and business impact.

3. Remediation Automation: Customers love our visibility but want more automated remediation. We're moving beyond recommendations to actual risk mitigation.

A Personal Thank You

To the customers who contributed to our Sentra Gartner Peer Insights success: thank you. Building a startup is often a lonely journey of best guesses and gut instincts. Your feedback is the compass that keeps us pointed toward solving real problems.

To the security professionals reading this: your honest feedback (both praise and criticism) makes our products better. If you're using Sentra, please keep telling us what's working and what isn't. If you're not, I'd love to show you what earned us Customer Choice 2025 recognition and why 98% of our customers recommend us.

The data security landscape is evolving rapidly. But with customers as partners and recognition like Gartner Peer Insights Customer Choice 2025, I'm confident we're building tools that don't just keep up with threats, they help organizations stay ahead of them.
