Upwind reels in $300M for its automated cloud security platform

Eight months after its previous nine-figure round, Upwind Security Inc. has raised $300 million in additional funding.

Returning bakers Bessemer and TCV led the Series C deal. CTech reported on Wednesday that the firms were joined by Salesforce Ventures, Greylock, Craft Ventures and several others. Upwind is now valued at $3.8 billion, $2 billion more than at the start of the year.

One of the main challenges involved in securing cloud environments is that they change on a regular basis. Developers frequently add and remove workloads, which makes it difficult to ensure that every software asset adheres to data protection policies. The same issue applies to instances and user accounts.

Upwind sells a platform that can automatically map out the assets in a cloud environment. It refreshes the data every 30 seconds to account for configuration changes.
