CRN's Top 25 Disrupters of the year are the executives who have shown an extraordinary ability to not only challenge the status quo but turn it on its ear. Here's a look at who made the cut, in Part 2 of our list of the Top 100 Executives of 2012.

CEO
Sonus

SIP infrastructure specialist Sonus has gone all in with its new push to deliver session border controllers to the enterprise, and Dolan is banking on the channel to help it get there, with the launch of a new SBC-specific partner program this June.

CEO
Embrane

Embrane is determined to push the boundaries of SDN and, in many ways, already has. Founded in 2009 and led by Malagrino, Embrane is expanding the SDN trend into Layer 4-7 functions with Heleos, its distributed software platform that powers virtual network services.

CEO
Forescout

Not only has Boyce helped establish ForeScout as a leading vendor in the network access control market, but he's ensured his company evolves alongside the changing needs of enterprise clients, most recently adding mobile security to ForeScout's already robust solutions portfolio.

CEO
Eucalyptus

Mickos has helped pioneer the hybrid cloud market, blending Eucalyptus' own private cloud offerings with Amazon Web Services' public cloud to offer enterprise users the best of both cloud computing worlds.

CEO
QlikTech

Despite competing against giants IBM, SAP and Oracle, QlikTech has thrived in the competitive business intelligence software arena under the direction of Bjork, with its in-memory analytics and data visualization solutions helping enterprises tackle the growing challenge of big data.

President
Intelisys

With Bradley at the helm, Intelisys has grown from master agent to a telco and cloud services powerhouse. Its May acquisition of the Cloud Services Coalition, coupled with its Cloud Services University program, are presenting VARs with more growth opportunities than ever before.

Senior VP and CTO
BMC

Behnia has stretched BMC's broad portfolio of system management solutions from on-premise to the cloud, most recently through a joint initiative with Amazon Web Services to delivered bundled cloud solutions to the enterprise.

President
World Telecom Group

Bradley has redefined what it means to be a master agent as he helps VARs profit not only from telecom, but energy usage costs and the cloud, through WTG's sister company Energent, and its cloud division Cloudology.

COO
Hewlett-Packard

HP may be the midst of a do-or-die transition, but its software division is growing, and Veghte is the one to thank. Veghte, who for almost two years spearheaded HP's software unit, grew the division 22 percent in the second quarter, before becoming COO.

CMO
EMC

Burton has not only become the face of EMC's channel charge, but has helped the storage giant step outside its usual enterprise and midrange boundaries and find a new customer base in SMBs as well.

GM, Application Performance Management
Compuware

Van Siclen has helped change the face of Compuware's Application Performance Management platform, broadening it to include must-have capabilities for modern data centers, such as monitoring solutions mobile, big data and cloud applications.

CEO
Symantec

When Symantec's first-quarter earnings plummeted nearly 10 percent this year, then-CEO Enrique Salem was out and Bennett was in. As Symantec's new CEO, Bennett, who from 2000 to 2007 led Intuit to more than double its revenue, is tasked with reviving the security giant.

iPhone & iPad Channel Development
Apple

Daumard is forging ahead with channel development efforts around Apple's iPhone and iPad devices, building goodwill in the channel where little existed before. His efforts to drive adoption of Apple's mobile devices in the enterprise have helped partners cash in on the BYOD craze.

CEO
Axcient

Moore has shaken up the cloud storage market with an unwavering focus on R&D and a firm belief that unified platforms -- not one-off products -- survive and thrive. His line of thinking has paid off: Axcient has grown 2,500 percent in three years.

CTO
Hortonworks

Baldeschwieler has not only helped transform his Yahoo spinoff into a big data bigwig, but is one of the founding fathers of Apache Hadoop, the open-source software framework that facilitates businesses' digestion and analysis of unstructured data.

CEO
Violin Memory

Basile serves as a reminder to storage giants such as EMC not to discount the little guys. Granted, the flash memory vendor isn't exactly "little" anymore; it's nabbed over $155 million in funding since its inception in 2005.

CEO
Zscaler

With only four years of business under its belt, startup cloud security vendor Zscaler has already wooed major customers including La-Z-Boy and Telefonica under Choundhry's direction. The company also raised an impressive $38 million in first-time funding this August.

CTO
AppSense

AppSense burst onto the scene in 2011, introducing user virtualization solutions that can cure even the toughest BYOD-related headaches. The company's ability to perfectly pinpoint and respond to market needs is rooted in Labana and his long-running love affair with R&D.

CEO
Nasuni

Rodriguez has been bullish in his efforts to deliver public storage clouds to the midmarket masses, providing a gateway solution that lets VARs add interfaces, bundled with their own storage services, to existing public clouds. The company just nabbed $20 million in funding.

Partner
Morrison Foerster

When Apple and Samsung faced off in U.S. court this August, it was McElhinny, Apple's lead lawyer, that led the Cupertino giant to victory. McElhinny, in successfully deeming Samsung a copycat, won his client a whopping $1.05 billion in damages.

CTO
Bromium

Crosby and his virtualization security startup have discovered a way to make PCs self-sufficient -- from a security standpoint, at least. Using its MicroVisor software, Bromium's new security technology fully vets an OS task before execution, allowing PCs, in essence, to monitor themselves.

Senior VP Engineering
Google

Apart from leading Google's social networking charge with the launch of Google+, Gundotra has helped grow Android into to the OS behemoth it is today, fostering Google's crucial relationship with developers.

Founder and CEO
Dropbox

Houston's Dropbox file-sharing service became a trailblazer in the cloud storage market, now boasting more than 100 million users. Since founding Dropbox five years ago, the 29-year-old visionary has since transformed the company into an enterprise-grade solution, launching admin tools to monitor and secure users' cloud-hosted files.

Sr. Director, Channel Business Development, Data Center
Cisco Systems

Since launching its first blade server in 2009, Cisco has shaken up the data center market and now sits among the top server vendors in the world. Growdon ensured that the channel came along for the ride, and he was rewarded when partners gave Cisco a sweeping victory in the midrange server category of CRN's 2012 Annual Report Card awards.

Co-founder and President
Symform

Five years ago, Garg set out to solve a problem. He knew the cloud represented a revolutionary new storage model, but noticed it was simply too expensive for many businesses to embrace. As a result, he created Symform. Founded alongside Bassam Tabbara, a colleague of Garg's while working on the engineering team at Microsoft, Symform has changed the way we think about the cloud by applying the universal rule "you only get what you give" to storage.

It works like this: Each user leveraging Symform's cloud-based storage contributes some of its own excess local storage in exchange, creating a sort of co-op, peer-to-peer network that is both inexpensive and secure -- and the idea, to put it lightly, has taken off. Garg already has nabbed $20 million in capital funding for the startup, all while fostering a dedicated group of followers that is poised for growth over the next few years.
