Testimonials

Sergii has a wonderful mix of talent — both on the tech side and in communications. I very much enjoyed working with Sergii at Comodo. Companies today need his blend of capabilities, although many of them still do not know it. Sergii acted as a mediator between narrow technical specialists and our technically non-educated audience, giving Comodo a great boost in visibility, in blogs, presentations, articles, and quarterly reports that covered a wide range of malware and cybersecurity issues.
