Independent, security-first evaluation of enterprise data security platforms. We assess encryption strength, access control architecture, threat detection capabilities, and data governance features for IT directors building defence-in-depth strategies.
Only three data security platforms are featured. Each is independently assessed across encryption capabilities, access architecture, threat detection, and data governance depth.
Varonis delivers a data security platform that combines automated data classification, access analytics, threat detection, and data governance into a unified solution. Purpose-built for discovering and securing unstructured data across file servers, NAS, cloud storage, and SaaS applications, Varonis provides the visibility security teams need to answer fundamental questions: where is sensitive data, who has access, and is that access appropriate? The platform's behavioural analytics detect threats that traditional tools miss by understanding normal user patterns and alerting on deviations.
IBM Guardium provides enterprise data security focused on protecting structured data in databases, data warehouses, and big data environments. The platform combines real-time database activity monitoring, vulnerability assessment, data classification, and encryption key management into a unified solution. For organisations with significant database-centric data estates — particularly in financial services, healthcare, and government — Guardium provides the depth of database security and compliance capabilities that general-purpose platforms cannot match.

Monitoring data movement is necessary. Making data architecturally resistant to breach is essential. Data security platforms provide the technical foundation that everything else depends on.
Properly encrypted data remains protected even when other security layers fail. Data security platforms provide the encryption and key management that ensure sensitive data stays secure regardless of where it resides or who attempts to access it.
Understanding who accesses data, how they use it, and whether that access is appropriate is fundamental to data security. Platforms with behavioural analytics detect insider threats and compromised accounts that perimeter security misses.
Data security platforms identify and remediate vulnerabilities in data stores before they're exploited. Proactive vulnerability management across databases, file systems, and cloud repositories reduces the attack surface available to adversaries.
Zero trust without data-centric security has a fundamental gap. Data security platforms provide the classification, access controls, and monitoring that make zero trust architecture complete at the asset level.
While often used interchangeably, data protection and data security address different priorities. Data protection focuses on preventing data loss through DLP, compliance automation, and policy enforcement. Data security takes a more fundamental approach: making data inherently harder to breach through encryption, access controls, vulnerability management, and threat detection. A comprehensive data security platform addresses both, but leads with the security-first mindset that infrastructure decisions should make sensitive data architecturally resistant to compromise — not just monitored for policy violations.
Data protection monitors what happens to data. Data security makes data fundamentally harder to breach. The best platforms do both, but understanding which priority drives your requirements determines which platform architecture fits.
The data security challenge differs fundamentally between structured data (databases, data warehouses) and unstructured data (files, documents, emails, cloud storage). Structured data security requires database activity monitoring, query-level inspection, vulnerability assessment, and encryption at the field and column level. Unstructured data security requires file-level discovery, classification, access analytics, and permission management across diverse repositories. Few platforms excel at both — evaluate your data estate to determine where your primary security gaps exist.
Zero trust architecture has become the prevailing security model, and data security platforms play a central role by providing the data-level controls that zero trust requires. Effective data-centric security verifies every access request against the sensitivity of the data being accessed, the identity and behaviour pattern of the requesting user, and the context of the access including device, location, and timing. Data security platforms that integrate access analytics with data classification enable the contextual access decisions that zero trust demands.
Many organisations implement zero trust at the network and identity layers but neglect the data layer. Without data-centric security controls — knowing what data is sensitive, who should access it, and whether current access patterns are appropriate — zero trust architecture has a fundamental gap at the asset it's ultimately designed to protect.
Encryption is the most fundamental data security control — properly encrypted data remains protected even if other security layers are breached. Evaluate data security platforms on encryption coverage (at rest, in transit, in use), key management capabilities (generation, rotation, revocation, and lifecycle management), and support for your specific regulatory requirements. Platforms that manage encryption keys separately from encrypted data provide stronger security than those where key management is co-located with the data store.
Evaluate encryption not just as a feature checkbox but as an operational capability. How are encryption keys managed when employees leave? How are keys rotated without downtime? What happens if a key is compromised? Key management operational procedures matter as much as encryption algorithm strength.
