AT&T Cybersecurity
Leading great experiences in Cybersecurity.
Overview
While Head of UX, I was tasked with redesigning our flagship SIEM platform while integrating the suite of cybersecurity products into a single pane of glass. The team identified information architecture deficiencies, an outdated UI framework, user workflow improvements, unseen feature requests and research improvements. During my tenure, I built and mentored a high-performing, multi-disciplined team of designers— fostering a culture of collaboration, autonomy, and innovation. I introduced agile workflows to align design with product roadmaps, improving visibility and delivery efficiency. I developed and taught user research practices grounded in Human Factors International principles to ensure intuitive and user-centered solutions.

Analysis
Strategic interactions with the product, sales and support team revealed areas for improved workflow features and helped align the design department with ongoing efforts. Close collaboration with engineering fostered a transparent understanding of technical limitations and a productive report to reduce tech debt and prioritize UX in product development. Deep research with security teams and customers highlighted feature requests and unseen improvements for our products.
Solutions
After considering business and product requirements, technical limitations and direct user feedback, I created a path for the team to achieve a list of UX outcomes. Basing the milestones on improving the experiences for operations teams and customers, managed and unmanaged. Major features like an inline AI assistant, a UI framework update to MUI, and enhanced workflow tools for investigations, team messaging and SOAR were top of the list.
AI Assistance
Leveraging an LLM and a UI agent, we were able to provide value for analysts throughout their day-to-day workflow. From a powerful search and filter assistant, to a generative report tool, and customizable role creations, users were delighted to decrease the time of usual tasks by more than half.
Refreshing and modernizing UI
The main platform when I came onboard used an older UI framework from Bootstrap. After negotiating with engineering, all teams agreed to implement Material UI for Angular. The update improved the aesthetics and added useful components aiding interactions for users. The updated data visualizations with chart.js also yielded strong feedback from analysts and customers.
Inclusive team messaging
Communication within operations teams is paramount. Analysts, managers and customers relied on peripheral applications to communicate to each other. To reduce extraneous cognitive load, we designed a messaging and notification center in the platform. This also allowed users to tag individuals or teams in notes for alarms, events or investigations.
Implementing SOAR
From concept to implementation, I guided the design work for SOAR technologies into the platform with product and engineering. We worked with subject matter experts and operations teams to solve for complex requirements such as action automations, rule association and plugin actions. The implemented design utilized a linear playbook interface that broke each step into a card that users could easily customize and add to the automation.
UX Milestones and Maturity Achieved
With over 10 UX milestones, my team achieved an enormous design effort. We decreased time on task for major actions executed by analysts. We fostered strong relationships across teams with user research while negotiating and meeting business requirements. The team has also increased design maturity across the company by showing the return on investment in design.
