Zero trust has largely evolved from concept to reality since it was first introduced to become a widely accepted and effective approach to cybersecurity. While companies have started to adopt zero trust, there still are some myths about it that need to be dispelled. Here are five such common myths about zero trust.
Myth: Zero trust security is too complex to implement
Reality: Cloud-based zero trust solutions can be deployed quickly and easily, thereby eliminating the deployment complexities of on-premise infrastructure. While zero trust security does require planning and coordination to set up, it simplifies security management in the long run. It does so by enforcing business policies inline, removing complex legacy hardware infrastructure, and eliminating the need for multiple management platforms to implement different policies and manage different network segmented zones. Additionally, there are a number of tools and services available to help organizations implement zero trust security.
Myth: Zero trust can be delivered by firewalls and VPNs
Reality: Firewalls, VPNs, or even virtual firewalls are perimeter-based security measures, meaning they are designed to protect the network from external threats by blocking or allowing traffic based on predetermined rules. These are not designed to deliver zero trust and cannot provide the continuous, granular access controls and identity verification that are central to a zero trust model. Zero trust mandates continuous verification of identity and trustworthiness of users, devices, and networks, regardless of their location or whether they are inside or outside the network perimeter.
Myth: Zero trust security is too expensive
Reality: The cost of implementing zero trust security will depend on the specific needs of the organization and the resources available to it. However, the cost of implementing zero trust security is often lower than the cost of managing traditional security systems, especially when the costs of data breaches and other security incidents are taken into account. Additionally, the cost of implementing zero trust security may be offset by the increased security and productivity it provides.
Myth: Zero trust security is not necessary for small organizations
Reality: Zero trust security is important for organizations of all sizes, as any organization can be the target of a cyberattack. Additionally, small organizations may be particularly vulnerable to attacks due to their limited resources and may not have the same level of security as larger organizations. Implementing zero trust security can help small organizations better protect their data and systems and reduce the risk of a successful attack.
Myth: Zero trust security requires a complete overhaul of your current security infrastructure
Reality: While a complete overhaul may be necessary in the long term, it's not always necessary to start by completely disrupting existing security infrastructure. You can often start by implementing zero trust solutions partially along with existing security infrastructure, and then gradually transitioning to a fully zero trust approach over time. For instance, first move an internal application, say M365, from a data center to a zero trust platform. Later, once IT builds confidence, they can move other applications gradually.
