ICT Consulting
Features Overview

Our Internet Gateway Security Solution begins with a consulting phase to evaluate your current needs, with the goal of developing a plan that you can use for future integration and growth.



The first step in our consulting engagement is to survey your current infrastructure. We interview your ICT and business personnel, locally and globally, to determine conditions of your current IT environment. This helps to clarify our understanding of your current situation and determine what issues need to be resolved.


Having assessed your environment, we begin to formulate an overall design for our proposed Internet Gateway Security Solution. We formulate a policy for various facets of the solution, such as data center, server, network, security, DR/BCP, user experience and operation monitoring. This formulation results in a plan of action for system migration, system restructure and operational changes.

Financial Analysis

The final element of our consulting phase is to calculate the return on investment (ROI) and total cost of ownership (TCO) for existing operations and for our proposed changes. We perform a comprehensive survey that involves observation of existing systems, calculation of the differences in requirements and an assessment of operational and personnel resources. Based on discussions with local users, we develop a TCO calculation sheet and compare this with the TCO and ROI of our propose solution.

The results of our survey, design and financial analysis consulting feed into the next phase: implementing your Internet Gateway Security Solution.
