After all these years of technical experience, i have developed the trouble isolation and resolution skills necessary system and network engineering and administration. In addition to my technical operational experiences I have used to build this business on I am the CISO for a large organization in Washington, DC. I would like to help small and medium sized business achieve the security postures the larger companies obtain on a much smaller budget. When I was in business school, I pushed the idea of fractional CISO services. A fractional CIO/CISO is targeted for small and large organizations that can benefit from a proven leader in delivering an IT security and operations program at a reduced cost for a Sr. executive leader. A fractional CISO/CIO would work with upper management of the organization to build an end to end security program strategy. Organizations with a security program can meet the due diligence requirements most businesses today have to comply with to reduce the risks of a data breach, loss of intellectual property, reputation damage and financial losses that would be associated with a breach. -Governance Risk and Compliance (GRC) -Security Operations Center (SOC) -Application Security -Incident Management / Incident Response / Breach Response -Identity Management and Access control -Business requirements mapped to IT technologies for maximizing revenues and operational efficiency More importantly to me, I get to create a partnership with my clients to develop a well balanced security program for the business and technical counterparts for the entire organization.
