Case Study Focus: The Legal Industry
The legal sector saw a record surge in ransomware attacks in 2024, and the FBI issued a 2025 advisory identifying threat groups consistently targeting U.S. law firms’ high-value data. Client trust and firm reputation depend on the confidentiality of sensitive M&A data, IP and patent filings, litigation strategies, privelaged communications, and more.
Spencer Fane LLP sought continuous assurance that their systems remained trustworthy, both within the office and across a globally mobile workforce. The Am Law 200 firm recognized that protecting data and preventing breaches requires more than traditional security tools.
“At Spencer Fane, safeguarding data is our highest priority. Invary’s ability to verify the integrity of our systems at runtime represents a significant advancement in security," said Wai Sheng Cheng, Information Security & Risk Manager, Spencer Fane LLP. "By reinforcing the foundation of our security posture, Invary enhances our ability to protect our critical data.”
Security Decisions Must Rely on Verified Systems
While evaluating Invary’s Runtime Integrity, Spencer Fane recognized that while traditional security tools are necessary, they rely on the integrity of the underlying systems. If that foundation is compromised, the telemetry those tools produce cannot be trusted.
Example:
An AI-driven attack beneath a firm’s security stack can surveil privileged files, exfiltrate data, and persist undetected for months while every tool above reports “all clear.”
“We had strong security tools in place. What we lacked was an independent way to confirm that the systems underneath them remained uncompromised. We needed to move from assuming trust to verifying it.” — Wai Sheng Cheng, Spencer Fane LLP
Deployment of Invary’s Runtime Integrity
With Invary’s Runtime Integrity deployed, Spencer Fane now operates with continuous, independent assurance that the systems remain uncompromised.
The lightweight Invary sensor introduced no performance impact to the firm’s existing applications and security stack, and the solution integrated into existing workflows without adding operational burden.
“Invary deployed quickly and cleanly across our environment with minimal lift.” — Wai Sheng Cheng, Spencer Fane LLP

Case Study Results:
Risk Reduction and Operational Resilience with Invary
Decisions based on unverified systems may lead to persistent compromise, extended dwell time, inefficient incident response, and operational disruption.
Invary’s Runtime Integrity enables security leaders’ confidence that their systems are in a known-good state and that existing security tools can be trusted.
