Gartner‘s senior director analyst, Brent Stewart, highlights six practices for building digital immunity. These practices protect sites, apps, and software without the need for human intervention.

“The purpose of the human immune system is to detect and respond to harmful pathogens and other foreign invaders to maintain the health and integrity of the body and to prevent system failure and downtime. What if sites, apps, and software could identify bugs and heal with little or no human intervention? Digital immunity aims to do just that,” Stewart explains.

He said that a digital immune system combines practices and technologies such as observability, AI-augmented testing, chaos engineering, auto remediation, sight reliability engineering, and software supply chain security to increase the resilience of products, services, and systems.

“These practices alone are sufficient to achieve the primary goal of a highly resilient system in combination though these six practices constitute a powerful approach to ensure that complex digital systems keep running even if the house is on fire,” he added.
