Cybereason is pleased to announce further expansion in North America with the addition of cybersecurity leaders Abigail Maines as Vice President of Commercial and Channel Sales, Stephan Tallent as Vice President of Managed Security Services Providers, and Ahmed Saleh as Vice President of IR and Advisory Program and Partnerships. 

“We are thrilled to have Abigail, Stephan and Ahmed join our team of defenders as we continue to expand our mission to end cyber attacks with an operation-centric approach that delivers immediate context into malicious operations across endpoints, users and the cloud,” said Shai Horovitz, Chief Revenue Officer, Cybereason.

“Demand for Cybereason products and services in North America is growing rapidly, so it’s critical to have a strong leadership team in place to keep pace with our expansion.”


Maines brings 20 years of industry experience to Cybereason where she will be working with partners on initiatives that will enhance sales enablement, demand generation and customer acquisitions. She will also be scaling Cybereason’s Commercial and SME sales efforts across North America.

She also launched multiple partner program enhancements and implemented rules of engagement that led to improved predictability for the Partner Community. Prior to that Maines led the global Business Development team at Cylance that was responsible for the company’s most strategic partnerships. 


Tallent will be working to onboard new partners and enable existing partners to grow revenue through partner margin-optimization for the MDR and IR service offerings. He will also be managing the MSSP Partner Program in North America and developing programs to further enable partner revenue growth.

While a Senior Director of MSSP at Fortinet, Tallent led service enablement, new partner onboarding, revenue optimization and go-to-market support for MSSP partners. He also developed programs designed to help MSSP partners launch new services, improve operational efficiencies and increase service margins. Prior to Fortinet, Tallent held positions at Masergy and Logix where he led the development of the first hosted services and cybersecurity practice.

He is a globally recognized and proven leader with more than 15 years of experience working in technology, incident response, strategy and security risk management. Most recently, He previously led the Content and Information Security team at Amazon Studios where he addressed evolving threats against sensitive assets.
