Another week, another VMware acquisition. Today the virtualization giant said it plans to buy Veriflow, a network verification startup. VMware didn’t disclose terms of the purchase.

The deal follows four other VMware acquisitions announced since May, and this week the company said it’s also in talks to buy sister company Pivotal.

VMware says it will use Veriflow’s technology to boost its networking monitoring, troubleshooting, and verification tools.

Founded in 2013, Veriflow has raised $11.1 million to date. It started shipping its software in 2016. A year later it extended the capabilities of its continuous network verification platform to hybrid clouds. In March, it introduced public cloud insights and visibility.

When the acquisition closes, VMware plans to integrate Veriflow into its vRealize Network Insight product, said Ajay Singh, SVP and GM of VMware’s Cloud Management business unit, in a blog post about the acquisition.

VMware’s network monitoring tool already provides unified troubleshooting and application-centric security planning and network visibility across private, public, and hybrid clouds. Veriflow’s technology adds advanced network verification and “what-if” analysis to the platform.

This latest acquisition continues VMware’s buying spree of late. The vendor last month acquired a pair of artificial intelligence (AI) firms: Uhana and Bitfusion. Uhana is being integrated into VMware’s Telco Cloud and Edge Cloud portfolios to bolster its 5G support, while Bitfusion will boost its ability to support AI and machine learning workloads in its core vSphere virtualization platform.

In June, the vendor reached a deal to acquire Avi Networks, a software company that provides multi-cloud application delivery services.

And in May, VMware bought Bitnami, which provides application packaging targeted at container and Kubernetes environments. Late last year it paid  $550 million for Kubernetes-focused startup Heptio.
