I currently work freelance projects. I used to work for Vonage Business (VoIP service provider) as a VoIP Engineer and had been provisioning, troubleshooting, and maintaining VoIP services and networks for 7 years. I am also a Certified Ethical Hacker (CEH) through International Electronic Commerce Council. Certified Ethical Hacker (CEH) is a qualification obtained by demonstrating knowledge of assessing the security of computer systems by looking for weaknesses and vulnerabilities in target systems, using the same knowledge and tools as a malicious hacker, but in a lawful and legitimate manner to assess the security posture of a target system. Hacking websites and discovering security vulnerabilities along with recommending remediation is my specialty. If your business is online, it is your business to ensure that it is secure.
