Microsoft's cyber startup spending spree continues with CloudKnox acquisition

·2 min read

Microsoft has acquired identity and access management (IAM) startup CloudKnox Security, the tech giant's fourth cybersecurity acquisition this year.

The deal, the terms of which were not disclosed, is the latest cybersecurity acquisition by Microsoft, which just last week announced that it’s buying threat intelligence startup RiskIQ. The firm also recently acquired IoT security startups CyberX and Refirm Labs as it moved to beef up its security portfolio. Security is big business for Microsoft, which made more than $10 billion in security-related revenue in 2020 — a 40% increase from the year prior.

CloudKnox, which was founded in 2015 and emerged from stealth two years later, helps organizations enforce least-privilege principles to reduce risk and help prevent security breaches. The startup had raised $22.8 million prior to the acquisition, with backing from ClearSky, Sorenson Ventures, Dell Technologies Capital and Foundation Capital.

The company's activity-based authorization service will equip Azure Active Directory customers with “granular visibility, continuous monitoring and automated remediation for hybrid and multi-cloud permissions,” according to a blog post by Joy Chik, corporate vice president of identity at Microsoft.

Chik said that while organizations were reaping the benefits of cloud adoption, particularly as they embrace flexible working models, they often struggled to assess, prevent and enforce privileged access across hybrid and multicloud environments.

“CloudKnox offers complete visibility into privileged access,” Chik said. “It helps organizations right-size permissions and consistently enforce least-privilege principles to reduce risk, and it employs continuous analytics to help prevent security breaches and ensure compliance. This strengthens our comprehensive approach to cloud security.”

In addition to Azure Active Directory, Microsoft also plans to integrate CloudKnox with its other cloud security services, including 365 Defender, Azure Defender and Azure Sentinel.

Commenting on the deal, Balaji Parimi, CloudKnox founder and CEO, said: “By joining Microsoft, we can unlock new synergies and make it easier for our mutual customers to protect their multi-cloud and hybrid environments and strengthen their security posture.”
