How Sunrun Transformed Security Operations with AiStrike

Sunrun Inc. is the largest residential solar and battery storage provider in the U.S., with over 10,000 employees supporting hundreds of thousands ofcustomers nationwide. As a public company in the energy sector, Sunrun’s IT security team is responsible for safeguarding critical systems, sensitive data, and customer trust across a complex hybrid environment.

Challenge : High Costs, Blind Spots, and Alert Fatigue

To keep up with daily alert volumes, Sunrun had outsourced Tier 1 alert triage and SIEM rule maintenance to a Managed Detection and Response (MDR) vendor. On paper, the model promised efficiency, but over time the results fell short of expectations:

Escalation Overload:

Nearly one in three alerts was escalated as an “incident,” stretching Sunrun’s lean team thin. Many of these were repeats or false positives, creating noise that distracted from true threats.

Detection & Coverage Gaps :

With limited detection engineering support, SIEM rules stagnated and key data sources weren’t integrated. This left blind spots that made it harder to stay ahead of emerging threats.

Limited Posture Improvement:

Minimal rule tuning and optimization meant the overall security posture saw little long-term improvement, despite significant ongoing spend.

High Cost, Limited Value:

The MDR service was costly, and the limited return on investment made it increasingly difficult to justify. With budgets tightening, Sunrun aimed to reduce spend while unlocking greater value from its existing investment in SIEM, SOAR, CNAPP, and threat intelligence tools.

Why Sunrun Chose AiStrike

As Sunrun looked for alternatives to its MDR provider, the team evaluated 
several options:

What made AiStrike different

Comprehensive SOC Fabric

Automation that covers the entire SOC lifecycle: detection engineering, investigation, response, and threat hunting.

Built-in SOAR + Case Management

A unified system of record, eliminating the need for separate tools.

Human-in-the-Loop Learning

Continuous improvement as AiStrike tunes detections and investigations with analyst feedback.

Threat Exposure Analysis

Intelligence from 100+ sources (Mandiant, Unit 42, Verizon DBIR, and more) drives proactive detections against emerging threats.

Agentless SaaS Deployment

Fast, seamless onboarding; operational in just two weeks without heavy infrastructure or agents.

For Sunrun, AiStrike wasn’t just a replacement for MDR — it represented a complete transformation of their SOC operating model.

Implementation: Fast, Seamless, and Scalable

Sunrun needed a solution that could be deployed quickly without disrupting existing workflows. AiStrike’s SaaS-first, agentless design made this possible.

Deployment Highlights:

The process was straightforward, and the impact was visible almost immediately.

Customer Perspective: A Shift from Noise to Control

For Sunrun’s lean security team, the difference between MDR and AiStrike was night and day. What had once been an endless cycle of noisy escalations quickly became a streamlined, controlled process with clear outcomes.

In Their Words:

“ When we relied on MDR, most of our time was spent chasing false positives and justifying costs. With AiStrike, that changed almost immediately. Every alert is now investigated, and instead of hundreds of escalations, we only see the handful that truly matter. We’ve cut costs in half, improved coverage, and gained a single place to investigate and respond. For the first time, our SOC feels efficient, proactive, and future-ready.  ”
