- Automated discovery and classification of sensitive data
- Access mapping and exposure analysis
- User behavior analytics to detect suspicious activity
- Guided remediation to reduce unnecessary access

4. Thales CipherTrust Data Security Platform
CipherTrust focuses on using encryption along with the control of cryptographic keys. Organizations can utilize CipherTrust to encrypt data on multiple platforms such as databases, files, containers, and cloud-based services, while at the same time maintain the centralized control over the customer’s cryptographic keys. CipherTrust provides organizations that are mandated by law to provide evidence of data confidentiality to regulators, or to ensure the service providers cannot have access to the protected data through encryption.
CipherTrust does not focus on how to monitor user behaviours; instead it is geared towards creating approximately the same level of security at a crypto-level.
Key Features
- Centralized encryption key and policy management
- Encryption and tokenization for structured and unstructured data
- Support for hybrid and multi-cloud environments
- Detailed audit logs for regulatory compliance

Imperva is a great match for companies that store and manage high-value or regulated data on their databases.
Key Features
- Discovery and classification across databases and cloud stores
- Activity monitoring with risk-based analytics
- Centralized policy enforcement
- Data masking for non-production environments

6. Velotix
Velotix focuses on governing access to data rather than locking it down completely. It discovers data across platforms, maps relationships, and automates access approvals so teams can use data safely. The platform is designed for modern analytics-driven organizations where fast access must coexist with security and accountability.
Velotix is particularly relevant for data teams working with cloud warehouses and analytics platforms.

Conclusion
Data security can be achieved through a combination of solutions that provide different levels of insight, authority, and action. By identifying sensitive information first they can minimize their exposure by making corrections to who has access to that information.
At that point, either DLP (data loss protection) or encryption can be applied where there is sufficient risk to warrant the need for protection. This methodology assists companies from spending money unnecessarily and helps to avoid creating security gaps.
FAQs
Q- What’s the difference between DSPM, DLP, and encryption solutions?
Ans– DSPM (Data Security Posture Management) discovers and maps sensitive data, highlights exposures, and prioritizes fixes. DLP (Data Loss Prevention) enforces rules that block or control data movement (endpoints, network, cloud). Encryption platforms (or KMS solutions) protect data by cryptographically controlling access to content and keys. Many mature programs combine discovery (DSPM), enforcement (DLP) and encryption for layered protection.
Q- Which tool is best for file servers and Microsoft 365 visibility?
Ans– Tools like Lepide emphasise file-server and Microsoft 365 visibility and provide continuous monitoring and audit reporting. Varonis also focuses on file shares and access mapping at scale. Choose based on depth of integration and reporting needs.
Q- How do I evaluate vendor ROI and operational cost?
Ans– Compare license fees plus operational effort: agent footprint, policy tuning time, false-positive handling, and integration effort. Ask vendors for a realistic TCO breakdown and proof points from similar customers.
Q- How do these tools help with audit and compliance?
Ans– Discovery tools create inventories and exposure reports; DLP and encryption solutions log enforcement actions. Together they produce auditable trails showing who accessed data, what actions were taken, and why a control was applied, speeding audit responses and reducing ad-hoc evidence collection.
