Phosphorus Poised for Record Growth with Appointment of New Chief Revenue Officer

Security industry veteran Shawn O’Brien will lead the company’s global sales and field operations during a period of significant growth and transformation for the xIoT security leader.

NASHVILLE, Tenn. Phosphorus, the leading provider of proactive and full-scope breach prevention for the xTended Internet of Things (xIoT), today announced the appointment of security industry veteran Shawn O’Brien to the position of Chief Revenue Officer. O’Brien will oversee Phosphorus’s global sales operations, including Sales Engineering, Channel and Alliance Development, and Customer Success. He joins the company at a time of accelerated sales and channel growth, as well as increased demand for its award-winning Unified xIoT Security Management Platform.

With three decades of executive and sales development experience in the security and IT industries, O’Brien will play a critical role in Phosphorus’s continued growth and expansion. As CRO, O’Brien will lead the company’s global sales and business development strategy as it sees increased demand by Fortune 500 companies in the energy, smart manufacturing, healthcare, biotech-pharmaceutical, retail, and financial sectors. Prior to joining Phosphorus, O’Brien served as the North America Vice President of Sales for Nozomi Networks, Americas Vice President – Enterprise Sales for Recorded Future, Americas Vice President for Netwitness Sales at RSA Security, and more. 

“Shawn is a well-respected industry leader who’s played an important role in developing the GTM strategies for several prominent security brands, and we are honored to have him as part of our senior leadership team,” said Chris Rouland, CEO of Phosphorus. “We are entering an exciting time in our company, as enterprises are eager to address their xIoT attack surface to protect their networks and smart devices proactively. Over the next year, we will be scaling our operations and GTM execution to enable more major enterprises to move from detection to prevention by discovering, assessing, hardening, remediating, and monitoring their non-IT assets to protect against critical new threats. We anticipate major growth across multiple industry verticals as we deliver the industry’s only unified solution for xIoT breach prevention and security management.”

O’Brien’s appointment marks an important next step for Phosphorus as the company finalizes its executive team in preparation for accelerated growth in H2 2023. Over the last year, Phosphorus appointed several leading industry executives as it expands its position as the market-defining solution for enterprise xIoT. These top executive hires include: John Vecchi, Chief Marketing Officer (Check Point, Blue Coat, McAfee); Martin LeRoy, Chief Financial Officer (SailPoint, Intel); Sonu Shankar, Vice President of Product Management (Arctic Wolf, Cisco, Box); Mike Huckaby, Vice President, Sales Engineering (Bugcrowd, RSA Security), Vlad Melnik, Vice President of Strategic Alliances (Splunk, Accenture); Drew Mullen, Vice President, Revenue Operations (Cylance, RSA Security); and Joe Costantini, Vice President of Engineering (Coinbase, Bastille).

Unique Market Position Puts Company on Track for Unicorn Status

While recession fears have led to cutbacks in some areas of corporate IT spending, the enterprise xIoT market remains remarkably strong. Recent forecasts predict a more than $2 trillion market for enterprise IoT by 2032. This massive increase in connected device integrations in corporate and industrial facilities is driving enormous demand for new services as business networks take on additional cyber risks that cannot be addressed with traditional security solutions.

Phosphorus holds a unique position in this fast-growing market, and as the only unified xIoT breach prevention platform, it is poised to become the first xIoT security unicorn. The company’s award-winning platform is the only enterprise security solution capable of providing proactive breach prevention and attack surface management – including Discovery and Assessment, Hardening and Remediation, and Detection and Response – across the full range of IoT, OT, IoMT, and IIoT devices, including both new and legacy technologies.
