We are excited to announce Sentra’s integration with Amazon Security Lake, a fully managed security data lake service enabling organizations to automatically centralize security data from various sources, including cloud, on-premises, and third-party vendors.

Our joint capabilities enable organizations to fast track the prioritization of their most business critical data risks, based on data sensitivity scores. What’s more, enterprises can automatically classify and secure their sensitive cloud data while also analyzing the data to gain a comprehensive understanding of their security posture.

Building a Data Sensitivity Layer is Key for Prioritizing Business Critical Risks

Many security programs and products today generate a large number of alerts and notifications without understanding how sensitive the data at risk truly is. This leaves security teams overwhelmed and susceptible to alert fatigue, making it difficult to efficiently identify and prioritize the most critical risks to the business.

Bringing Sentra's unique data sensitivity scoring approach to Amazon Security Lake, organizations can now effectively protect their most valuable assets by prioritizing and remediating the security issues that pose the greatest risks to their critical data.


Moreover, many organizations leverage third-party vendors for threat detection based on security logs that are stored in Amazon Security Lake. Sentra enriches these security events with the corresponding sensitivity score, greatly improving the speed and accuracy of threat detection and  reducing the response time of real-world attacks.

Sentra's technology allows security teams to easily discover, classify, and assess the sensitivity of every data store and data asset in their cloud environment. By correlating security events with the data sensitivity layer, a meaningful data context can be built, enabling organizations to more efficiently detect threats and prioritize risks, reducing the most significant risks to the business.

OCSF Opens Up Multiple Use Cases

The Open Cybersecurity Schema Framework (OCSF) is a set of standards and best practices for defining, sharing, and using cybersecurity-related data. By adopting OCSF, Sentra seamlessly exchanges cybersecurity-related data with various security tools, enhancing the efficiency and effectiveness of these solutions. Security Lake is one of the vendors that supports OCSF, enabling mutual customers to enjoy the benefit of the integration.

This powerful integration ultimately offers organizations a smart and more efficient way to prioritize and address security risks based on the sensitivity of their data. With Sentra's data-first security approach and Security Lake's analytics enabling capabilities, organizations can now effectively protect their most valuable assets and improve their overall security posture.

What the HIPAA Compliance Updates Mean for Your Security

What the HIPAA Compliance Updates Mean for Your Security

The Health Insurance Portability and Accountability Act (HIPAA) has long been a cornerstone of safeguarding sensitive health information in the U.S., particularly electronic protected health information (ePHI). As healthcare organizations continue to face growing cybersecurity challenges, ensuring the protection of ePHI has never been more critical. 

In response, for the first time in two decades, the U.S. Department of Health and Human Services (HHS) has proposed significant amendments to the HIPAA Security Rule, aimed at strengthening cybersecurity measures across the healthcare sector. These proposed changes are designed to address emerging threats and ensure that healthcare organizations have robust systems in place to protect patient data from unauthorized access and potential breaches. This blog presents the major changes that are coming soon and how you can prepare for them.

What You Need to Know About the Proposed HIPAA Security Rule Updates

The latest proposed updates to the HIPAA Security Rule represent some of the most significant changes in years. These updates aim to modernize data protection practices and ensure healthcare organizations are better equipped to handle today’s security challenges. Below are the key highlights compliance and security teams should focus on:

Mandatory Implementation Specifications
All implementation specifications under the HIPAA Security Rule will become mandatory. Covered entities and business associates must now fully comply with all safeguards—no more "addressable" exceptions.

Stricter Encryption Requirements
Encryption of electronic protected health information (ePHI) will be required both at rest and in transit. Organizations must ensure encryption is in place across all systems handling sensitive data.

Required Multifactor Authentication (MFA)
MFA will become mandatory to protect access to ePHI. This added security layer significantly reduces the risk of unauthorized access and credential compromise.

Network Segmentation for Threat Containment
Organizations must implement network segmentation to isolate sensitive systems and limit the spread of cyber threats in the event of a breach.

Timely Termination of Access
Access to ePHI must be revoked within 24 hours when an employee leaves or changes roles. This reduces the risk of insider threats and unauthorized access.

Comprehensive Documentation Requirements
Healthcare organizations must maintain detailed, up-to-date documentation of all security policies, procedures, risk assessments, and incident response plans.

Asset Inventories and Network Mapping
Annual updates to technology asset inventories and network maps will be required to ensure accurate tracking of where and how ePHI is stored and transmitted.

Enhanced Risk Analysis
Organizations must conduct regular, thorough risk assessments to identify vulnerabilities and assess threats across all systems that interact with ePHI.

Stronger Incident Response Plans
Entities must be able to restore lost systems and data within 72 hours after a cyber incident. Regular testing and refinement of incident response protocols will be essential.

Annual Compliance Audits
Healthcare organizations will be required to conduct annual audits of their HIPAA Security Rule compliance, covering all technical and administrative safeguards.

Mandatory Technical Controls
Technical safeguards like anti-malware tools, firewalls, and port restrictions must be in place and regularly reviewed to protect systems from evolving threats.

What’s Next?

The proposed changes to the HIPAA Security Rule are currently in the Notice of Proposed Rulemaking (NPRM) stage, with a 60-day public comment period that opened on January 6, 2025. During this period, stakeholders can provide feedback on the amendments, which may influence the final rule. Organizations should actively monitor the comment period, engage in the feedback process, and stay informed on any potential adjustments before the rule is finalized.

Steps Organizations Should Take Now:

  • Review the proposed changes and understand how they impact your current security posture.
  • Engage in the public comment process to share concerns or recommendations.
  • Start assessing security gaps to align with HIPAA’s evolving compliance requirements.

Conclusion

The new HIPAA compliance amendments represent a major shift in how healthcare organizations must protect electronic Protected Health Information (ePHI). The introduction of enhanced encryption standards, mandatory multi-factor authentication (MFA), and stricter access control measures means organizations must act swiftly to maintain compliance and reduce cybersecurity risks.

How to Scale DSAR Compliance (Without Breaking Your Team)

How to Scale DSAR Compliance (Without Breaking Your Team)

Privacy regulations such as GDPR (EU), CCPA/CPRA (California), and others are not just about legal checkboxes, they’re about building trust. In today’s data-driven world, customers expect organizations to be transparent about how their personal information is collected, used, and protected. When companies take privacy seriously, they demonstrate respect for their users, which in turn fosters loyalty and long-term engagement.

But among the many privacy requirements, Data Subject Access Requests (DSARs) can be the most complex to support. DSARs give individuals the right to request access to the personal data that an organization holds about them—often with a firm deadline of just 30 days to respond. For large enterprises with data scattered across multiple systems, both in the cloud and on-premises, even a single request can trigger a chaotic search across different platforms, manual reviews and legal oversight—it quickly becomes a race against the clock, with compliance, trust, and reputation on the line.

Key Challenges in Responding to DSARs

Data Discovery & Inventory
For large organizations, pinpointing where personal data resides across a diverse ecosystem of information systems, including databases, SaaS applications, data lakes, and legacy environments, is a complex challenge. The presence of fragmented IT infrastructure and third-party platforms often leads to limited visibility, which not only slows down the DSAR response process but also increases the likelihood of missing or overlooking critical personal data.

Linking Identities Across Systems
A single individual may appear in multiple systems under different identifiers, especially if systems have been acquired or integrated over time. Accurately correlating these identities to compile a complete DSAR response requires sophisticated identity resolution and often manual effort.


Unstructured Data Handling
Unlike structured databases, where data is organized into labeled fields and can be efficiently queried, unstructured data (like PDFs, documents, and logs) is free-form and lacks consistent formatting. This makes it much harder to search, classify, or extract relevant personal information.

Response Timeliness
Regulatory deadlines force organizations to respond quickly, even when data must be gathered from multiple sources and reviewed by legal teams. Manual processes can lead to delays, risking non-compliance and fines.

Volume & Scalability
While most organizations can handle an occasional DSAR manually, spikes in request volume — driven by events like regulatory campaigns or publicized incidents — can overwhelm privacy and legal teams. Without scalable automation, organizations face mounting operational costs, missed deadlines, and an increased risk of inconsistent or incomplete responses.


The Role of Data Security Platforms in DSAR Automation

Sentra is a modern data security platform dedicated to helping organizations gain complete visibility and control over their sensitive data. By continuously scanning and classifying data across all environments (including cloud, SaaS, and on-premises systems) Sentra maintains an always up-to-date data map, giving organizations a clear understanding of where sensitive data resides, how it flows, and who has access to it. This data map forms the foundation for efficient DSAR automation, enabling Sentra’s DSAR module to search for user identifiers only in locations where relevant data actually exists - ensuring high accuracy, completeness, and fast response times.

Another key factor in managing DSAR requests is ensuring that sensitive customer PII doesn’t end up in unauthorized or unintended environments. When data is copied between systems or environments, it’s essential to apply tokenization or masking to prevent unintentional sprawl of PII. Sentra helps identify misplaced or duplicated sensitive data and alerts when it isn’t properly protected. This allows organizations to focus DSAR processing within authorized operational environments, significantly reducing both risk and response time.

Smart Search of Individual Data

To initiate the generation of a Data Subject Access Request (DSAR) report, users can submit one or more unique identifiers—such as email addresses, Social Security numbers, usernames, or other personal identifiers—corresponding to the individual in question. Sentra then performs a targeted scan across the organization’s data ecosystem, focusing on data stores known to contain personally identifiable information (PII). This includes production databases, data lakes, cloud storage services, file servers, and both structured and unstructured data sources.

Leveraging its advanced classification and correlation capabilities, Sentra identifies all relevant records associated with the provided identifiers. Once the scan is complete, it compiles a comprehensive DSAR report that consolidates all discovered personal data linked to the data subject that can be downloaded as a PDF for manual review or securely retrieved via Sentra’s API.

DSAR Requests

Establishing a DSAR Processing Pipeline

Large organizations that receive a high volume of DSAR (Data Subject Access Request) submissions typically implement a robust, end-to-end DSAR processing pipeline. This pipeline is often initiated through a self-service privacy portal, allowing individuals to easily submit requests for access or deletion of their personal data. Once a request is received, an automated or semi-automated workflow is triggered to handle the request efficiently and in compliance with regulatory timelines.

  1. Requester Identity Verification: Confirm the identity of the data subject to prevent unauthorized access (e.g., via email confirmation or secure login).

  2. Mapping Identifiers: Collect and map all known identifiers for the individual across systems (e.g., email, user ID, customer number).

  3. Environment-Wide Data Discovery (via Sentra): Use Sentra to search all relevant environments — cloud, SaaS, on-prem — for personal data tied to the individual. By using Sentra’s automated discovery and classification, Sentra can automatically identify where to search for.

  4. DSAR Report Generation (via Sentra): Compile a detailed report listing all personal data found and where it resides.

  5. Data Deletion & Verification: Remove or anonymize personal data as required, then rerun a search to verify deletion is complete.

  6. Final Response to Requester: Send a confirmation to the requester, outlining the actions taken and closing the request.

Sentra plays a key role in the DSAR pipeline by exposing a powerful API that enables automated, organization-wide searches for personal data. The search results can be programmatically used to trigger downstream actions like data deletion. After removal, the API can initiate a follow-up scan to verify that all data has been successfully deleted.

Benefits of DSAR Automation 

With privacy regulations constantly growing, and DSAR volumes continuing to rise, building an automated, scalable pipeline is no longer a luxury - it’s a necessity.


  • Automated and Cost-Efficient: Replaces costly, error-prone manual processes with a streamlined, automated approach.
  • High-Speed, High-Accuracy: Sentra leverages its knowledge of where PII resides to perform targeted searches across all environments and data types, delivering comprehensive reports in hours—not days.
  • Seamless Integration: A powerful API allows integration with workflow systems, enabling a fully automated, end-to-end DSAR experience for end users.

By using Sentra to intelligently locate PII across all environments, organizations can eliminate manual bottlenecks and accelerate response times. Sentra’s powerful API and deep data awareness make it possible to automate every step of the DSAR journey - from discovery to deletion - enabling privacy teams to operate at scale, reduce costs, and maintain compliance with confidence. 

Turning DSAR Compliance into a Scalable Advantage

As privacy expectations grow and regulatory pressure intensifies, DSARs are no longer just a checkbox. They are a reflection of how seriously an organization takes user trust. Manual, reactive processes simply can’t keep up with the scale and complexity of modern data environments.

By automating DSAR workflows with tools like Sentra, organizations can achieve faster response times, lower operational costs, and sustained compliance - while freeing up teams to focus on higher-value privacy initiatives.
