VentureBeat recently spoke with Jerry R. Geisler III, the Executive Vice President and Chief Information Security Officer at Walmart Inc., to discuss the company’s approach to cybersecurity amidst the rise of autonomous AI technologies. Geisler highlighted that the increasing use of agentic AI presents new security threats, including data exfiltration and misuse of APIs, which traditional security measures may struggle to address.
To tackle these challenges, Walmart is adopting advanced AI Security Posture Management (AI-SPM) for continuous monitoring and regulatory compliance. Geisler emphasized the need for a customized strategy adapted to Walmart’s scale, drawing on a startup mindset to modernize identity and access management systems.
The conversation also delved into Walmart’s hybrid multi-cloud infrastructure, which includes Google Cloud, Azure, and private cloud environments. Geisler indicated that access policies are determined by identity rather than network location, ensuring consistent application of Zero Trust principles across different environments.
With the rise of sophisticated phishing threats facilitated by AI, Walmart is employing the same technology to bolster its defenses. The company is using machine learning models to identify anomalies and simulate attack scenarios as part of its incident response strategy. This proactive approach aims to fortify defenses against advanced threats.
Geisler also addressed Walmart’s initiatives to attract and train cybersecurity talent, noting programs that offer education in cybersecurity and related fields. The company’s annual SparkCon event serves as a platform for knowledge sharing among professionals in the field.
Reflecting on Walmart’s centralized AI platform, Geisler mentioned that a unified architecture enables both rapid innovation and security compliance, allowing for a concentrated defense against evolving threats. The lessons learned from developing this platform will continue to shape Walmart’s strategic decisions regarding AI technologies and security.
