Secure enterprise search: GDPR compliant, SOC 2 certified

by Monika Kisielewska7 min readJanuary 3, 2025

Most enterprise search systems create a centralized index or database by copying an organization’s data, instead of querying it directly at the source. While this approach is efficient, it introduces significant security and compliance risks. 

In contrast, Qatalog’s no-index approach redefines enterprise search by retrieving data in real-time without storing or duplicating it. This innovation offers secure enterprise search—making Qatalog a game-changer in the field.

The biggest risk is that a centralized database creates a single point of failure—if compromised, it exposes all organizational data. This includes:

  • The complete knowledge base of the organization in one place

  • An interconnected map of sensitive data relationships

  • Access to confidential client data, internal communications, and intellectual property

  • Severe financial consequences in the event of a breach

Permission management in indexed enterprise search tools also creates multiple security vulnerabilities, from sync delays to complex system interactions, all of which can lead to unauthorized data access.

Permission sync vulnerabilities

The delay between permission changes in source systems and their reflection in search indexes creates dangerous windows of opportunity:

  • Terminated employees retaining access

  • Privilege escalation attacks

  • Accidental exposure of sensitive data

  • Compliance violations during transition periods

Permission synchronization challenges

Most enterprise search tools attempt to mirror your existing permission systems, leading to:

  • Complex permission synchronization issues

  • Potential access control gaps during updates

  • Risk of temporary permission misconfigurations

  • Increased chance of unauthorized access

Data freshness vs. security

The conflict between index freshness and security creates serious risks:

  • Outdated indexes may expose deleted sensitive data

  • Real-time index updates can create security race conditions

  • Incomplete permission updates can lead to data leaks

  • Cache invalidation issues can expose restricted content

Compliance challenges span multiple dimensions, from basic data storage requirements to complex data subject rights, making traditional enterprise search systems difficult to align with modern privacy regulations.

Data storage compliance

  • Data minimization violations: Creating unnecessary data copies

  • Storage limitations: Difficulty enforcing retention policies

  • Geographic data restrictions: Challenges with cross-border data

Permission and access compliance

  • Access control documentation: Managing permissions across copies

  • Audit trail requirements: Tracking access across multiple systems

  • Permission sync violations: Compliance risks during sync delays

Data subject rights

  • Right to be forgotten: Complexity of removing all data copies

  • Access requests: The challenge of identifying all stored copies

  • Data portability: Difficulty managing data across systems

Introducing a secure enterprise search solution

Qatalog eliminates the risks of data replication by adopting a real-time, API-based search architecture. Instead of copying data, Qatalog retrieves it directly from the source in real time, providing a more secure and compliant solution. Here’s how it works:

1. No index architecture

Qatalog’s architecture eliminates the need for a central repository, significantly reducing the attack surface. Hackers cannot target a single location containing all your organization’s data.

2. Simplified compliance

By accessing data at its original source data minimization becomes inherent (only the necessary data is accessed) storage limitation is adhered to (no unnecessary duplicates are created).

3. Dynamic access controls

Every search query triggers real-time permission checks against the source system. This ensures access controls are always current and eliminates vulnerabilities caused by outdated permissions.

1. Real-time accuracy

By fetching data directly from its source, Qatalog ensures that the information users retrieve is always up-to-date. This eliminates the risk of making decisions based on outdated data.

2. Cost savings

Maintaining a centralized index requires significant storage and computational resources. Qatalog reduces these costs, making it a more efficient solution for enterprises.

3. Faster implementation

Traditional search platforms often require a lengthy indexing process during setup. Qatalog can be implemented quickly, enabling organizations to immediately benefit from secure enterprise search.

4. Lower maintenance

With no centralized repository to manage, Qatalog simplifies system maintenance. IT teams can focus on other priorities without worrying about securing and updating an additional database.
