A Chief Information Security Officer (CISO) has requested that a SIEM solution be implemented. The CISO wants to know upfront what the projected TCO would be before looking further into this concern. Two vendor proposals have been received:
Vendor A: product-based solution which can be purchased by the pharmaceutical company.

Capital expenses to cover central log collectors, correlators, storage and management consoles

expected to be $150,000. Operational expenses are expected to be a 0.5 full time employee (FTE) to manage the solution, and 1 full time employee to respond to incidents per year.
Vendor B: managed service-based solution which can be the outsourcer for the pharmaceutical

company's needs.
Bundled offering expected to be $100,000 per year.
Operational expenses for the pharmaceutical company to partner with the vendor are expected to be a 0.5 FTE per year.
Internal employee costs are averaged to be $80,000 per year per FTE. Based on calculating TCO of the two vendor proposals over a 5 year period, which of the following options is MOST accurate?
