Cisco is doing its public relations a little differently, lately. On December 8, Cisco CEO Chuck Robbins tweeted his congratulations to David Ulevitch on his promotion to group leader of the company’s security business.

Ulevitch joined Cisco in 2015 when his startup OpenDNS was acquired for $635 million. The OpenDNS team merged into Cisco’s security business group under then-SVP David Goeckeler.

But this summer, Goeckeler’s own job expanded considerably when he was named senior vice president and general manager of the networking and security business group.

Goeckeler has said Cisco is focused on building a security portfolio with both organic and inorganic investments. In 2016 Cisco acquired the security start-up CloudLock, adding to its portfolio of other security acquisitions, including Portcullis, Lancope, and SourceFire.

At Cisco Live 2016, Goeckeler announced three new branch office security products, stemming from the startups that Cisco has acquired. And he also announced one homegrown security product — Cloud Defense Orchestrator.

In its most recent earnings report, Cisco reported that although its overall product revenue dropped, security, which is in that segment, increased 11 percent. Cisco's Robbins said it was the fourth consecutive quarter in which security garnered double-digit growth.

EWeek, which was first to notice the tweet about Ulevitch’s promotion, quotes him as saying, "We're one of the only companies, if not the only company, with a $2 billion revenue run rate in security that is growing double-digits. FireEye isn't doing that, Palo Alto Networks isn't doing that, and Check Point isn't doing that either."

451 Research Analyst Peter Christy says Cisco has an advantage in security because its networking equipment is so widely deployed, providing a built-in platform for security sensors. “Cisco has the surface area for sensors and is the dominant provider,” he says. “Security used to be focused on PC endpoints. As we move to mobile, all of that breaks down, and you have to do more in the network.”
