EDR: Endpoint Agent Modernization & Stalled Project Recovery

Led the modernization of the EDR agent across Windows, macOS, and Linux, resolving long standing operational issues, improving OS parity, and delivering customer driven enhancements. Revitalized a stalled agent initiative and delivered a GA ready release within three months, restoring customer confidence and enabling future roadmap execution.

Context and objectives

• Product type: Endpoint Detection & Response (EDR) agent deployed across enterprise environments
• Business drivers: Improve stability, OS coverage, supportability, and customer experience; reduce operational friction for SOC and Support
• Constraints: Legacy architecture, inconsistent OS parity, certificate lifecycle issues, limited documentation, and a stalled multi team project
• Success criteria: Deliver a GA ready release, improve OS parity, reduce support escalations, and establish a sustainable modernization path

Role and scope

• Title: Product Manager / Product Owner
• Scope: Owned product direction, roadmap, backlog, and cross functional alignment across Engineering, Architecture, SOC, Support, and Customer Success
• Project length: Ongoing ownership, with a focused three month rescue and delivery window for the stalled initiative

Problem statement

The EDR agent suffered from architectural limitations, scalability challenges, inconsistent OS parity, certificate lifecycle issues, and a backlog of customer requested enhancements. A critical agent initiative had stalled for nearly a year, blocking customer commitments and delaying downstream roadmap items.

Approach and strategy

• Discovery: Reviewed architectural designs, support tickets, engineering backlog, SOC feedback, and customer escalations to identify root causes and prioritize fixes
• Prioritization: Balanced customer impact, technical feasibility, and risk; focused on addressing scalability, resolving blockers and high value enhancements
• Roadmap cadence: Established a clear sequence for modernization, OS parity improvements, and supportability enhancements

Execution and key activities

• Identified missing requirements and gaps across Engineering, Architecture, and Support that had stalled the agent initiative
• Rebuilt the backlog with clear acceptance criteria, technical dependencies, and sequencing
• Coordinated engineering workstreams across Windows, macOS, and Linux to improve OS parity
• Led certificate lifecycle redesign to eliminate recurring operational issues
• Delivered customer driven enhancements, including expanded OS support and improved supportability features
• Established a repeatable release readiness process for future agent updates
• Partnered with Support and Customer Success to validate fixes and prepare customer facing communication

Technical architecture and modernization areas

• OS coverage: Windows, macOS, Ubuntu, Debian, RHEL
• Modernization focus:
• Increase scalability
• Certificate lifecycle redesign
• OS parity improvements
• Supportability enhancements
• Legacy architectural cleanup
• Operational improvements: Reduced support escalations, improved agent reliability, and enabled future roadmap execution

Deliverables and artifacts

• Rebuilt product backlog with clear requirements and acceptance criteria
• Updated architecture and dependency documentation
• Release readiness plan and cross team coordination model
• Customer facing release notes and upgrade guidance
• Internal training materials for Support and Customer Success

Results and metrics

• Delivery: GA ready release delivered in three months after nearly a year of stalled progress
• Stability: Improved agent reliability and eliminated recurring certificate related issues
• Customer impact: Delivered long requested enhancements and expanded OS support
• Operational impact: Reduced support escalations and improved SOC visibility into agent behavior
• Strategic impact: Unblocked future roadmap items and restored confidence in the agent’s evolution

Challenges and mitigations

• Stalled initiative: Rebuilt requirements, clarified ownership, and established a milestone driven plan
• Legacy architecture: Partnered with Architecture to identify safe modernization paths
• OS parity gaps: Coordinated cross OS engineering workstreams to align capabilities
• Support escalations: Prioritized fixes with highest customer and operational impact

Lessons learned and next steps

• Early cross team alignment prevents drift and stalls
• Comprehensive requirements discovery to define project completion
• Clear acceptance criteria accelerate engineering execution
• Modernization requires incremental, validated steps rather than large monolithic changes
• Next steps: migration to newer code base, expanded OS support, and enhanced upgrade automation
