Laminar Security vs Sentra
Side-by-side comparison of AI visibility scores, market position, and capabilities
Data security posture management for public clouds acquired by Rubrik in 2023. Discovers and classifies cloud data at rest across AWS, Azure, and GCP; now integrated into Rubrik's data security platform to extend DSPM alongside backup and recovery capabilities for enterprise customers.
About
Laminar Security was a data security posture management company founded in 2020 by Amit Shaked and Oran Avraham, headquartered in Tel Aviv, Israel, with offices in New York. The company built a DSPM platform focused on discovering, classifying, and monitoring sensitive data at rest across public cloud environments, with the goal of helping security and data governance teams understand where their sensitive data lived, how it was exposed, and whether access controls were appropriately configured. Laminar's autonomous scanning approach required no agents and integrated via cloud-native APIs.\n\nLaminar raised $67 million in funding before being acquired by Rubrik in 2023 for a reported $200 million. Rubrik, a cloud data management and cyber resilience company, acquired Laminar to add data security posture management capabilities to its existing platform, which specializes in backup, recovery, and ransomware protection. The combination gave Rubrik customers visibility into where sensitive data lived in cloud environments alongside Rubrik's existing capabilities for protecting and recovering that data from cyber attacks.\n\nPrior to the acquisition, Laminar served enterprise customers in financial services, healthcare, and technology that were struggling with data governance in multi-cloud environments. The platform's classification engine covered hundreds of sensitive data categories and integrated with compliance frameworks for GDPR, CCPA, HIPAA, and PCI DSS. Laminar's approach to showing data lineage — tracking how sensitive data moved between cloud services and databases — was a differentiating capability that Rubrik cited as a key motivation for the acquisition.
NYC/Tel Aviv cloud DSPM platform; raised $55M+; autonomous data discovery and classification with privacy-first design for enterprise cloud environments.
About
Sentra is a cloud data security company founded in 2021 and headquartered in New York City, with engineering based in Tel Aviv, Israel. The company was founded by Yoav Regev, Ron Reiter, and Asaf Kochan — including alumni of Israeli intelligence Unit 8200 — to address the growing challenge of data sprawl in cloud environments. Sentra's platform autonomously discovers sensitive data across cloud-native data stores, databases, data pipelines, and SaaS applications, classifies it using contextual AI, and surfaces data security risks without requiring any data to leave the customer's own environment.\n\nSentra raised $55 million in funding from investors including Standard Investments, Moore Strategic Ventures, and Bessemer Venture Partners. Its privacy-first architecture differentiates Sentra from some competitors: the platform analyzes data metadata and structure within the customer's cloud environment rather than sending data samples to an external service for classification, addressing a common concern organizations have about DSPM vendors accessing their most sensitive information. The platform integrates with AWS, Azure, GCP, and cloud-native data services including Snowflake, Databricks, and Redshift.\n\nSentra's use cases include cloud data asset inventory for compliance and governance, detection of shadow data stores created by developers without security oversight, identification of over-permissioned data access by users and service accounts, and continuous monitoring for data movement that could indicate an exfiltration attempt or accidental exposure. The platform provides remediation guidance that routes to both security teams and the data owners responsible for each store.
