The most cost-effective way of protecting a network from threats can depend on the size and type of organization, as well as the level of security that is required. Organizations should assess their own needs and implement solutions that fit within their allocated budget, such as utilizing open-source tools or investing in managed services. Utilizing multi-factor authentication, encryption, and other preventative measures are also key components for establishing secure networks. By evaluating different options and choosing the most suitable solution for their specific environment, organizations can ensure they are able to securely protect their networks while staying within budget.
