In a landmark moment for data security, Sentra, a trailblazer in cloud-native data protection, has raised $50 million in Series B funding, bringing its total funding to over $100 million. The round was led by Key1 Capital with continued support from top-tier investors like Bessemer Enterprise Partners, Zeev Ventures, Standard Investments, and Munich Re Ventures.
This recent investment arrives at a pivotal time, with AI adoption exploding across enterprises and bringing with it a tidal wave of sensitive data—and recent security risks. Sentra, already experiencing 300% year-over-year growth and seeing fast adoption amongst Fortune 500 firms, is now doubling down on its mission: empowering organizations to innovate with AI without compromising on data security.
The AI Boom’s Dark Side: Unseen Risks in “Shadow Data”
While AI opens doors to unprecedented innovation, it also introduces a hidden threat—shadow data. As firms rush to harness the ability of GenAI, data scientists and engineers incessantly duplicate, move, and manipulate data across environments. Much of this activity flies under the radar of traditional security tools, resulting in invisible data sprawl and growing compliance risks.
Gartner predicts that by 2025, GenAI will drive a 15% spike in data and application security spending, as organizations scramble to plug these emerging gaps. That’s where Sentra is available in.
What Makes Sentra Different?
Sentra’s Cloud-Native Data Security Platform (DSP) doesn’t just bolt security onto existing infrastructure. As a substitute, it’s designed from the bottom as much as autonomously discover, classify, and secure sensitive data—whether it lives in AWS, Azure, Google Cloud, SaaS apps, on-prem servers, or inside your AI pipeline.
At the center of Sentra’s platform is an AI-powered classification engine that leverages large language models (LLMs). Unlike traditional data scanning tools that depend on fixed rules or predefined , Sentra’s LLMs understand the business context of knowledge. Which means they will discover sensitive information even in unstructured formats like documents, images, audio, or code repositories—with over 95% accuracy.
Importantly, no data ever leaves your environment. Sentra runs natively in your cloud or hybrid environment, maintaining full compliance with data residency requirements and avoiding any risk of exposure in the course of the scanning process.
Beyond Classification: A Full Security Lifecycle
Sentra’s platform combines multiple layers of knowledge security into one unified system:
-
DSPM (Data Security Posture Management) constantly assesses risks like misconfigured access controls, duplicated sensitive data, and misplaced files.
-
DDR (Data Detection & Response) flags suspicious activity in real-time—corresponding to exfiltration attempts or ransomware encryption—empowering security teams to act before damage occurs.
-
DAG (Data Access Governance) maps user and application identities to data permissions and enforces least privilege access, a key principle in modern cybersecurity.
This approach transforms the once-static notion of knowledge protection right into a living, respiratory security layer that scales with your enterprise.
Led by a World-Class Cybersecurity Team
Sentra’s leadership team reads like a who’s who of Israeli cyber intelligence:
-
Asaf Kochan, President, is the previous Commander of Unit 8200, Israel’s elite cyber intelligence unit.
-
Yoav Regev, CEO, led the Cyber Department inside Unit 8200.
-
Ron Reiter, CTO, is a serial entrepreneur with deep technical expertise.
-
Yair Cohen, VP of Product, brings years of experience from Microsoft and Datadog.
Their shared vision: to reimagine data security for the cloud- and AI-first world.
And the market agrees. Sentra was recently named each a Leader and Fast Mover within the GigaOm Radar for Data Security Posture Management (DSPM), underscoring its growing influence in the safety space.
Constructing a Safer Future for AI
The $50 million boost will allow Sentra to scale its operations, grow its expert team, and enhance its platform with recent capabilities to secure GenAI workloads, AI assistants, and emerging data pipelines. These advancements will provide security teams with even greater visibility and control over sensitive data—across petabyte-scale estates and AI ecosystems.
said CEO Yoav Regev.
As AI adoption accelerates and regulatory scrutiny tightens, Sentra’s approach may thoroughly develop into the blueprint for contemporary enterprise data protection. For businesses seeking to embrace AI with confidence, Sentra offers something powerful: security that moves on the speed of innovation.
