Cloud security vendor Lacework today said it closed a record-breaking $1.3 billion funding round on an $8.3 billion valuation.

It’s the cybersecurity unicorn’s second record-setting investment in less than a year. In January, Lacework announced a $525 million Series C funding round, which, at the time, was the largest-ever in security industry history.

“And not too long after that, we started hearing expressions of interest from current and potential new investors to invest even more in the company because they see the promise of the market, and they see the progress that we’ve been making,” Lacework CFO Mike Staiger said.

So the company and its investors blew the earlier round out of the water with another round of financing.

Existing investors Sutter Hill Ventures, Altimeter Capital, D1 Capital Partners, and Tiger Global Management led the new Series D funding round with participation from new investors including Franklin Templeton, Morgan Stanley Investment Management, Durable Capital, General Catalyst, and XN. Coatue, Dragoneer, Liberty Global, and Snowflake Ventures, all existing investors, also participated.

“Certainly the amount of the financing, $1.3 billion, is unprecedented in the in the security space, and so we’re excited to have had such a large bet placed on us in this space,” Staiger said. “It enables us to chart a very aggressive course as we invest in a range of areas in the company.”

Specifically, this includes growing the Lacework workforce (it counts more than 700 employees now) and the company’s reach globally. The cloud security vendor already has a strong presence in North America and Europe, the Middle East, and Africa. Last month it expanded into the Asia-Pacific region with new offices in Australia and New Zealand. “We want to build big, fast-moving teams in all of these geographies, and that requires a significant investment,” Staiger said.

Lacework will also use the new capital to build out its Cloud Security Platform by enhancing its existing capabilities and adding new use cases, Staiger said. “Whether that’s in the areas of cloud configuration, or cloud security, audit logs, runtime protection, vulnerability, etc. There are new use cases across all those dimensions, and this is going to allow us to selectively target those kinds of expansions in the product capabilities.”

The Series D also provides extra cash to buy smaller companies, and Staiger pointed to last week’s Soluble acquisition as a good example. This was Lacework’s first acquisition, and Soluble’s technology will help Lacework customers integrate security earlier in the software delivery process by remediating infrastructure as code flaws.

Lacework competes against several other vendors in the cloud security space, but the biggest is Palo Alto Networks — the largest security vendor by revenue in the world. However, Lacework continues gaining market share and it expects that trend to continue, Staiger said.

“Whenever we get into a proof of concept where we’re in a head-to-head competition, we win the vast majority of the time, and it doesn’t matter who the vendor is,” he said “We recognize the stakes are very, very high because the market is so large and it’s going to be growing very rapidly for many years.”

The latest funding round validates this belief, Staiger added. “It’s a validation of many things including the fact that from a competitive standpoint, we’re winning a lot and we’re taking market share as it becomes available — in many cases taking market share from competitors who are our incumbents.”
