Su: VMware Announces Intent to Acquire Pivotal and Carbon Black

Team,

I am very pleased to share that we made important announcements today regarding our intent to acquire two public companies. The acquisitions of these companies will fundamentally accelerate our Any Cloud, Any App, Any Device strategy as we help drive our customers’ digital transformation agendas. The first, Pivotal, is a leading provider of a multi-cloud developer platform that is transforming and accelerating the way the world develops software. They also are a member of the Dell Technologies family of companies. The second, Carbon Black, is a leading provider of an innovative cloud-native security platform and also a long-time strategic partner of ours.

These are the largest and first public transactions in our company’s history but more importantly, they are further proof that our dual-pronged strategy of investing in organic and inorganic innovation is gaining momentum. Our organic innovation engine remains strong and we will continue creating core, disruptive technologies that change the industry. We can also be proud of our proven ability to effectively acquire and integrate leading-edge companies. After these transactions close, we will be the only company able to deliver software solutions that enable customers to build, run, manage, connect and protect any app, on any cloud and any device.

Together with Pivotal and Carbon Black, we will advance our goal of offering more comprehensive and trusted multi-cloud solutions. Pivotal will transform our customers’ ability to build, run and manage modern apps with velocity and efficiency as well as further strengthen our credibility with developers and Carbon Black will help us deliver a highly differentiated (enterprise-grade) security portfolio that transforms our customers’ ability to protect workloads, clients and applications from device to cloud.

Pivotal

Acquiring Pivotal builds upon the Kubernetes investments we’ve made over the last two years and supports our strategy to accelerate the adoption of the Kubernetes platform as the de facto standard for multi-cloud infrastructure. Specifically, Pivotal will extend our portfolio with the products, tools and services necessary to create the only one-stop shop capable of building, running and managing Kubernetes-based applications with velocity and efficiency. Together, we will be well-positioned to capitalize on increasing customer demand for an enterprise Kubernetes solution that accelerates software delivery for modern apps on any cloud. For more detail, read Paul Fazzone’s blog, GM of the Cloud Native App (CNA) Business Unit.

Carbon Black

With Carbon Black joining the VMware family, we will take a huge step forward in delivering an enterprise-grade platform to protect workloads, applications and networks — from device to cloud. As a result of this combination, and for the first time in the industry, workload security will be agentless and endpoint management and security will be collapsed into a unified solution, providing tremendous additional value to customers.

Carbon Black’s innovative security cloud platform leveraging big data analytics provides comprehensive protection of endpoints and a defense against a variety of threats. The combination of Carbon Black’s solutions with VMware’s security products including AppDefense, Workspace ONE, NSX and SecureState will create a modern security cloud platform that can protect workloads, clients and applications for Any App running on Any Cloud. This ground-breaking, highly differentiated, intrinsic security platform will provide customers advanced threat detection and in-depth application behavior insight to stop sophisticated attacks and accelerate responses.

With this acquisition, VMware will take a significant leadership position in security for the new age of modern applications and devices that exist in a multi-cloud world. For more detail, please see Tom Corn’s blog, Senior Vice President of Security Products.

Looking Forward

Once the transactions close, I know you will join me in extending a warm welcome to the Pivotal and Carbon Black teams. This is a major milestone for all of us and I want to personally thank the VMware, Carbon Black and Pivotal teams that have worked tirelessly and in close partnership to make these transactions possible. The next steps of integration and transition planning will require even more collaboration and diligence and we have much to learn from each other. I’m confident that our agile, innovative and community-oriented cultures will blend well together and will get us through any challenges we face as we integrate teams.

Subject: VMware Announces Intent to Acquire Carbon Black (FORWARD CASCADE OF PAT’S EMAIL)

Date: 8/22, following Pat’s email

EUC Team,

I hope you had a chance to read Pat’s message below. The EUC leadership team and I are very excited about the synergies with Workspace ONE and the opportunity (when the deal closes) to significantly accelerate Workspace ONE growth. The capabilities Carbon Black brings will allow us to double down on the Workspace ONE zero trust security proposition, significantly add value to Workspace ONE Intelligence and expand our footprint in endpoint security.

Please note that we have not yet closed this transaction, and we cannot talk about our “combined” strategy and deliverables externally until that occurs. Close is expected by the end of FY20, and at that time, we will work closely with the Carbon Black team on our integration plans. Until that time, please refer to the FAQs for additional information and for more on what you can and cannot say to anyone outside of VMware.

This news adds great momentum to our story as we head into VMworld next week, and I look forward to hearing the excitement from our customers. Let’s stay focused on the work at hand, and I’ll see many of you next week in San Francisco.

Su: Customer and Partner Resources for Pivotal and Carbon Black Announcements

Team,

VMware made some exciting announcements today regarding two important acquisitions. If you haven’t already, please read Pat’s summary on Source. We announced our intent to acquire Pivotal, a leading provider of a multi-cloud developer platform that is transforming and accelerating the way the world develops software; and Carbon Black, a leading provider of an innovative cloud-native security platform and a long-time strategic partner of ours.

I am personally excited to serve as executive sponsor for Security and for Carbon Black’s transition to VMware. Security has been a passion of mine, just like many of our other new product areas, like Containers, so together with Pivotal, I couldn’t be more excited about the potential of these two great acquisitions.

As many of us are heading to VMworld US next week and will be responding to customer and partner questions through ongoing interactions, I wanted to reiterate a few key points:

Key Takeaways from the Announcements:

• VMware’s vision is to support our customers’ digital transformation by delivering a multi-cloud software architecture that enables any app on any cloud delivered to any device.

• These two acquisitions directly support our vision. They will enable us to address key strategic IT priorities—building apps with a modern approach and protecting enterprise applications and endpoints.

• With Pivotal, VMware will be able to deliver an integrated modern apps portfolio combining Pivotal’s next-generation developer platform and VMware’s Kubernetes portfolio.

• With Carbon Black, VMware will be able to provide a next generation security cloud with Carbon Black’s protection suite and VMware’s intrinsic security assets.

• Adding these companies to VMware’s portfolio will allow the company to deliver software solutions that enable customers to build, run, manage, connect and protect any app, on any cloud and any device.

What to Expect Between Now and Close

It is important to note that these transactions have not closed – we expect both to close before the end of FY20. During this period, we will partner closely with the acquired companies’ leadership teams and our business leaders to work through the details of the integration and ensure a smooth transition. It is business as usual at both companies for now and we will provide updates, as they are available.

I look forward to seeing many of you at VMworld next week and for those of you who have been preparing for Momentum Season around the world – thank you!

Best,

Sanjay
