Optery VS Apache Sentry

• Data Privacy Enhancement
  Optery helps individuals manage and remove their personal data from data brokers, enhancing their online privacy and reducing unwanted exposure.
• Ease of Use
  Optery provides a user-friendly interface to guide users through the process of data deletion, making it accessible even for those with limited technical knowledge.
• Comprehensive Coverage
  The service covers a wide range of data broker sites, increasing the chances of personal data removal across multiple platforms.
• Time-Saving
  Instead of individuals having to manually contact each data broker, Optery automates the process, saving users considerable time and effort.

Possible disadvantages

• Subscription Cost
  Optery typically operates on a subscription model, which may be a recurring cost that not all users are willing to incur.
• Variable Success Rates
  The effectiveness of data removal can vary, as success depends on the compliance of individual data brokers.
• Limited Control
  Users might feel they have less direct control over the data removal process compared to handling it manually.
• Residual Data
  Even after using Optery, there might still be residual data left online due to the constantly changing nature of data collection and sharing practices.

• Fine-Grained Authorization
  Apache Sentry allows for detailed control over who can access what data, providing more robust data security by allowing settings at the level of resources such as databases, tables, columns, and views.
• Integration with Hadoop Ecosystem
  Sentry is designed to integrate seamlessly with other components in the Hadoop ecosystem, such as Hive, Impala, and HDFS, allowing for consistent security policies across different services.
• Role-Based Access Control (RBAC)
  It uses a role-based access control model which simplifies the process of managing permissions by assigning roles to users that define their access rights.
• Audit Capabilities
  Apache Sentry provides auditing capabilities that record who accessed what resources and when, which aids in compliance and security monitoring activities.

Possible disadvantages

• Complex Configuration
  Setting up and configuring Sentry can be complicated, requiring substantial technical expertise and understanding of both Sentry and the systems it integrates with.
• Performance Overhead
  Implementing fine-grained access control and auditing can introduce latency and impact the overall performance of the Hadoop cluster.
• Limited Community and Support
  As compared to other Apache projects, Sentry may have less community support and fewer third-party resources or plugins, potentially making troubleshooting and customization more difficult.
• Deprecation Concerns
  With the evolution of more contemporary security projects such as Apache Ranger, there is a concern that Apache Sentry might not be as actively updated or supported in the future.

  I opted to pay for optery.com to do all the legwork for me. It’s a yearly subscription but doesn’t seem too steep for what I get. They send you regular reports with before and after screenshots of said sites showing your information... Source: almost 4 years ago
