Meet Mark Anthony Germanos
I’m Mark Anthony Germanos, the owner of Cyber Safety Net and the person behind the services and publishing banner you see here.
I began providing computer training in 1992 and have taught students across multiple states and countries. I hold CompTIA’s Security+ and SecAI+ certifications and deliver training on both. This includes published Security+ instruction on Udemy.
Self-employed since 1997, I have supported clients with seven-figure and eight-figure businesses. My experience includes ethical hacking, PCI assessments and disaster recovery planning. This background supports my practical approach to technology and cybersecurity, with attention to business needs, security risks and preparation for disruptions.
For network support and training engagements, I’m your point of contact, coordinating independent specialists and external providers where appropriate. My focus is clear communication, defined responsibilities and services matched to your needs. Our publishing banner also brings fiction and nonfiction to readers, including books by Lynne Denver.
