A framework and strategy review for managing network & security transformation is much needed. Every CIO, CISO, and CTO today will be assessing their ongoing costs to run and operate a secure network and security programme for 2021 and beyond. In parts 1 & 2 of this three-part series, I explained what numbers should feed these calculations and measurements and how performance, flexibility, and scalability are all key to this transformation. We are now in a critical stage to decide what our networks and security programmes will look like in the near future…and we only have one chance to get it right.
Driving top-line growth while improving the bottom line with operational cost efficiencies
Ask a board what their ultimate goal for digital transformation is and it’s improving top-line growth whilst applying operational cost efficiencies to maintain a healthy bottom line. Transformation does come with new costs, but as project teams become more experienced with digital transformation, so come the economic efficiencies.
This same approach applies to network and security transformation. We now have organisations that have followed the same design principles and have moved, or are moving, their security technologies and controls to the cloud. These skill sets are in high demand as more and more organisations realise the value of this transformation. This move also allows the organisation to simplify its budget projections and focus on expense management by reducing its unpredictable CAPEX expenditure and moving to a predictable OPEX subscription-based model that supports operational cost efficiencies. More on this later. In summary, a win-win. Not only is this simpler to forecast, but as security becomes a services-based industry, it will support cost avoidance and will allow for additional consolidation opportunities.
Gone are the days of routing traffic through the public internet and through a myriad of appliances all making attempts to inspect and decode traffic with the team needing to perform regular reviews for each appliance to assess ROI/TCO and asking the obvious question: “Do we still need this and is there a better option?” Today, all organisations have the opportunity to use cloud-based microservices when the needs arise without expensive design and architectural reviews. To think of this as an analogy, it’s similar to booking an international trip and using a dozen airlines and airports to get you to your destination. Every flight connection requires another security check where you and your baggage needs to be scanned. Now consider paying a huge premium for this. Given a choice, everyone will instead choose a cost-effective direct option with the same or better security applied on demand. This is what network and security transformation should be about, simple, fast, and secure without unnecessary delays.
Flexibility outside the bounds of IT
As we transform our networks and security and move our security controls to the cloud, we must assess how we think about forecasting and budgeting. Securing a user (I much prefer to refer to users as employees) in our environment is an expense typically assessed for each budgetary year. If we have 20,000 employees, it’s obvious that it’s going to be more expensive and require more resources than securing 2,000 employees. The issue with organisations is that they cannot accurately predict what their employee count will look like in the 3-5 years ahead. The challenge is mergers and acquisitions (M&A), a change agent that occurs for most organisations that will shake up any IT and security strategy. With M&A, predicting onboarding costs usually involves thinking about new hardware or even replacement hardware to scale to the organisation’s new requirements. These types of challenges can take months to plan for and apply, and will typically slow an organisation down at a critical time. However, as organisations embrace and use the cloud, we can systematically use the flexible
