Last week, another container security startup came off the board when Rapid7 bought Alcide for $50 million. The purchase is part of a broader trend in which larger companies are buying up cloud-native security startups at a rapid clip. But why is there so much M&A action in this space now?

Palo Alto Networks was first to the punch, grabbing Twistlock for $410 million in May 2019. VMware struck a year later, snaring Octarine. Cisco followed with PortShift in October and Red Hat snagged StackRox last month before the Rapid7 response last week.

This is partly because many companies chose to become cloud-native more quickly during the pandemic. This has created a sharper focus on security, but it would be a mistake to attribute the acquisition wave strictly to COVID-19, as companies were shifting in this direction pre-pandemic.

It’s also important to note that security startups that cover a niche like container security often reach market saturation faster than companies with broader coverage because customers often want to consolidate on a single platform, rather than dealing with a fragmented set of vendors and figuring out how to make them all work together.

Containers provide a way to deliver software by breaking down a large application into discrete pieces known as microservices. These are packaged and delivered in containers. Kubernetes provides the orchestration layer, determining when to deliver the container and when to shut it down.

This level of automation presents a security challenge, making sure the containers are configured correctly and not vulnerable to hackers. With myriad switches this isn’t easy, and it’s made even more challenging by the ephemeral nature of the containers themselves.

Yoav Leitersdorf, managing partner at YL Ventures, an Israeli investment firm specializing in security startups, says these challenges are driving interest in container startups from large companies. “The acquisitions we are seeing now are filling gaps in the portfolio of security capabilities offered by the larger companies,” he said.
