GreatHorn Names Ann Sharon Vice President of Operations

Former CloudLock Executive to Drive Enterprise Adoption of Next-Generation Email Security Platform to Thwart Phishing Attacks

Belmont, MA – February 7, 2018 – GreatHorn, the leader in next-generation email security that protects enterprises from advanced threats, today announced that it has made a key appointment to the management team: Ann Sharon as Vice President of Operations.

“Ann brings tremendous industry experience and insight, gained from working with a range of cybersecurity and technology organizations, ranging from early-stage startups to high-growth organizations and market leaders,” said GreatHorn CEO Kevin O’Brien. “She is a valuable addition to the management team as we look to drive market awareness and customer demand for our innovative, next-generation email security solution while optimizing and scaling our business operations to support rapid expansion.”

Sharon previously served as Vice President of Business Operations for CloudLock where she helped drive the company’s go-to-market strategy and led many cross-functional programs before the company was acquired by Cisco. Sharon also oversaw the product and program management operations for EMC’s secure remote support portfolio.

Email threats, while not new, increasingly have become more sophisticated. Enterprises using cloud-based email platforms like Microsoft Office 365 and Google G Suite find that legacy email gateway technology does not provide sufficient protection against advanced threats including targeted phishing, business email compromise, malware and ransomware. GreatHorn is the only cloud-native email security solution that protects against advanced threats and provides post-delivery remediation, without requiring MX rerouting or introducing email latency. Lynch and Sharon join the GreatHorn management team as the company has received a groundswell of recognition, including being named a Cool Vendor in Gartner’s report, Cool Vendors in Cloud Security, 20171a finalist in the 2017 RSAC Innovation Sandbox, as well as one of CB Insights’ 10 Email Security Startups to Watch.
