Disclaimer: About Our Avatars
At Abacus IT, we’ve chosen to represent our team using avatars. As a fully remote cybersecurity company, this approach allows us to maintain a consistent, modern, and professional presentation while prioritizing the privacy and security of our team members. In today’s cybersecurity landscape, personal photos are increasingly exploited in identity theft, social engineering, and deepfake attacks. By using avatars, we minimize exposure to these threats and set an example of the proactive, security-first mindset we apply to protecting our clients’ data and systems.
