Onyxia Cyber Welcomes Karen Mesoznik as Vice President of Marketing

Cybersecurity Management startup taps former Perimeter 81 marketing leader to spearhead its go-to-market efforts

We are proud and excited to welcome Karen Mesoznik as Onyxia’s Vice President of Marketing. A seasoned marketing and media professional with over 15 years of industry experience, Mesoznik was previously a founding team member and Senior Director of Corporate Marketing at Perimeter 81, where she scaled the Corporate Marketing department from seed series to Unicorn.

As VP of Marketing, Mesoznik will oversee and lead Onyxia’s strategic go-to-market strategy and efforts including brand development; content, field, product, and channel marketing; public and analyst relations, and demand generation activities.

“I am thrilled to welcome Karen to the team,” Sivan Tehila, CEO and Founder of Onyxia Cyber said. “I worked closely with Karen at Perimeter 81, where we shaped the now well-established Zero Trust industry in its early days and introduced Perimeter 81 as a leader in the field. I am confident that with Karen spearheading our marketing, Onyxia Cyber, will achieve similar market recognition and cement its place as a leader and innovator in the new category we are shaping – Cybersecurity Management.”

Under Mesoznik’s marketing leadership, Perimeter 81, acquired by Checkpoint Technologies, evolved from an early-stage startup to a well-recognized unicorn –  achieving Gartner® Cool Vendor and Forrester New Wave™ recognition, growing 400% year-over-year in ARR, developing partnerships with global technology leaders including Microsoft, Amazon AWS, and Ingram Micro, and acquiring thousands of customers.

“I am proud to join Onyxia’s leadership team,” Mesoznik said. ”I’m not only motivated by the fact that I believe Onyxia’s Cybersecurity Management Platform addresses a significant need in the market but as a woman in cyber, I’m also energized at the prospect of joining a female-founded cybersecurity startup. I am passionate about seeing more women in tech, and moreover, tech leadership roles.”

Mesoznik joins an accomplished leadership team that includes Eugene Brodsky, CTO, previously CTO at Perimeter 81, and Vadim Pogulievsky, VP of Product Management, who served in senior product management roles at leading cybersecurity companies like Cybereason, Verint, and McAfee.
