    I'm a Website Business Consultant and Cyber Security Expert. I can help you with Server Infrastructure, Website Security, Virtualization technologies, WordPress Security, Website Security, E-mail Marketing (making sure your messages make it to the inbox of your intended recipients). I also specialize in PCI Compliance, HIPAA Compliance, GDPR configuration, TLS setup, and anything related to security and automation on the server-side (for example, automating an offsite backup strategy for your server). I can move sites from one server to another (including e-mails) for example, manage the DNS, setup failover systems, and probably too much to mention here. Get in touch with me, you won't be disappointed. I've been a member since 2003!! :-) less
