Sentra 融资 150M系列 C 扩展代理数据安全平台
在 Google 上的首选来源中添加 Unite.AI
2026年11月4日Sentra 宣布，Capital One Ventures在代理数据安全公司领导了1.5亿美元的战略投资。 C系列融资将扩大Sentra管理雇员、应用程序和AI agents获取的企业数据及其上市业务的平台。
Capital One Ventures 加入现有投资者 Bessemer Venture Partners, Zeev Ventures，标准投资，慕尼黑再风险公司和Key1 Capital. 一名代表也将加入森特拉的董事会。 Sentra报告说，在宣布之前的一年里，年比增长超过300%。
AI Agents 改变数据安全问题
Sentra正在解决的问题有三处同时变化：快速部署copilots，助手和云AI服务；敏感数据散布在云，SaaS和promess系统之间；以及AIagents乘以身份，以机器速度连续访问数据。 由此导致的分散可能使安全小组无法持续了解敏感记录的存放地点和哪些人或系统可以接触到他们。
森特拉期望大型组织在几年内从少数agents放大成指数级以上，而只有少数组织说它们有治理控制agent数据访问。 这改变了接入治理的规模：必须与雇员和服务账户一起绘制机器快速身份的许可图。
共同创始人兼CEOYoav Regev将AI agents定性为企业数据最繁忙的消费者，称许多人继承了尚未完全分类或治理的信息获取权。 他仅依靠周边控制的选择是，在agents行动前，获取其居住地点的数据，并规范哪些人和AI身份可以到达。
Agent活动之前、期间和之后的管理数据
Sentra的方法始于休息时的数据，而不是检查每次agent请求。 该平台涵盖云服务，SaaS应用程序，数据仓库，proposes文件共享和AI使用的知识库。 在agents行动前，它发现并分类敏感数据，为人绘制地图访问，服务账户和agents，包括继承权限，对非人类身份实施最小特权，并删除冗余，过时和高风险的数据。
在一次事件中，数据意识检测旗不寻常地获得敏感信息。 自动补救可以取消访问，消除风险共享，并将高风险问题传递给数据所有人和现有工作流程。 之后，Sentra 显示可以获取哪些agent信息，并为安全、法律和合规小组提供关于受影响数据集的业务环境。
分析完全在客户环境中进行，没有将敏感数据移入Sentra自己的环境中。 Sentra 称这种设计避免了单独建立一个复制的数据产业园，以及随之而来的留存、居住和合规风险，这是受监管行业的重大考虑。
产品开发和商业扩展筹资
产品投资将针对agents,copilots和模型的更广泛的能见度以及它们接触的敏感数据，人类身份和非人类身份的持续最小特权，数据休息的保护，以及当agent行为出乎意料时的快速封禁。 Sentra还计划扩大现场和频道节目，增加品牌和营销活动，并进入新的地理图。
Lyft CISO Chaim Sanders 称他的组织采用Sentra来支持它的成长，确定它的agents在激活它们穿过它的环境之前可以到达什么数据，让安全帮助AI的推出而不是放慢。
回合将森特拉的扩张与一个具体的控制问题联系起来：在agents行动前减少敏感数据曝光和不必要的访问，同时保留遏制和调查事后事件的手段。 对于部署agents的企业，融资支持一种模式，在agent活动之前建立数据治理，而不是留待逐项请求检查。

Sentra Raises $150M Series C to Expand Agentic Data Security Platform
Add Unite.AI to your preferred sources on Google
Sentra announced on November 4, 2026, that Capital One Ventures led a $150 million strategic investment in the agentic data-security company. The Series C financing will expand Sentra’s platform for governing enterprise data accessed by employees, applications and AI agents, as well as its go-to-market operations.
Capital One Ventures joins existing investors Bessemer Venture Partners, Zeev Ventures, Standard Investments, Munich Re Ventures and Key1 Capital. A Capital One representative will also join Sentra’s board of directors. Sentra reported more than 300% year-over-year growth in the year preceding the announcement.
AI Agents Change the Data-Security Problem
Three simultaneous changes define the problem Sentra is addressing: rapid deployment of copilots, assistants and cloud AI services; sensitive data spreading across cloud, SaaS and on-premises systems; and AI agents multiplying as identities that access data continuously at machine speed. The resulting fragmentation can leave security teams without a continuous picture of where sensitive records reside and which people or systems can reach them.
Sentra expects large organizations to scale from a handful of agents to exponentially more within a few years, while only a small minority say they have governance controlling agent data access. That changes the scale of access governance: permissions must be mapped for machine-speed identities alongside employees and service accounts.
Co-founder and CEO Yoav Regev characterized AI agents as the busiest consumers of enterprise data and said many inherit access to information that has not been fully classified or governed. His alternative to relying solely on perimeter controls is to secure data where it resides and govern which human and AI identities can reach it before agents act.
Governing Data Before, During and After Agent Activity
Sentra’s approach starts with data at rest rather than inspection of every agent request as it happens. The platform covers cloud services, SaaS applications, data warehouses, on-premises file shares and knowledge stores used by AI. Before agents act, it finds and classifies sensitive data, maps access for people, service accounts and agents, including inherited permissions, enforces least privilege for non-human identities, and removes redundant, obsolete and high-risk data.
During an incident, data-aware detection flags unusual access to sensitive information. Automated remediation can revoke access, remove risky sharing and route high-risk issues to data owners and existing workflows. Afterward, Sentra shows what information an agent could have reached and provides business context about the affected datasets for security, legal and compliance teams.
The analysis runs entirely inside the customer’s environment, without moving sensitive data into Sentra’s own environment. Sentra says this design avoids creating a separate copied data estate and the retention, residency and compliance risks that can accompany it, a material consideration for regulated industries.
Funding Product Development and Commercial Expansion
Product investment will target broader visibility into agents, copilots and models and the sensitive data they touch, continuous least privilege for human and non-human identities, protection of data at rest, and rapid containment when an agent behaves unexpectedly. Sentra also plans to scale field and channel programs, increase brand and marketing activity and enter new geographies.
Lyft CISO Chaim Sanders said his organization adopted Sentra to support its growth, determine what data its agents can reach before activating them across its environment, and let security assist the AI rollout rather than slow it down.
The round ties Sentra’s expansion to a specific control problem: reducing sensitive-data exposure and unnecessary access before agents act, while retaining the means to contain and investigate incidents afterward. For enterprises deploying agents, the financing backs a model in which data governance is established ahead of agent activity rather than left to request-by-request inspection.
