Case Study:
A Midwest telecom company tested Invary’s ability to strengthen its security stack against the many threats seeking to disrupt infrastructure and essential services.
Their focus was system-level compromise, a common attack vector. For instance, Salt Typhoon targeted systems to evade traditional security tools and maintain undetected access for months using living-off-the-land techniques that blended into normal operations.
“There have been a number of attacks by state actors on telecommunications companies,” said the security team. “While we would be considered a "small fish", there is still significant danger from these attackers.”
Security Tool Bake-Off
The Midwest provider’s security team introduced a Red Team compromise on test systems and observed whether EDR/MDR solutions detected it.
Result: Though at least one other vendor explicitly claimed detection capability in this area, only Invary detected the change.
“Our recent Pen Test proved some visibility problems on our network, and we are actively working to add layers of protection. Invary looked to be a good fit.”
Both organizations realized that without visibility into the integrity of the operating system itself, they could not be fully confident in the effectiveness of their existing tools.
Attacks Undetectable by EDR/XDR
Attacks are increasingly engineered to target systems to bypass security tools.
35% of malware bypass EDR/XDR altogether (Mandiant), and zero-day attacks are increasing 50% year-over year (Google Threat Analysis Group).
Traditional security detection fails to surface this class of compromise, allowing breaches to persist undetected with an average dwell time of 212 days (IBM Cost of a Data Breach Report).
Security Decisions Must Rely on Verified Systems
While evaluating Invary’s Runtime Integrity, the company 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 see Invary's service as an additional layer for our monitoring defense. As shown in the tests I performed against EDR solutions, the changes to the kernel in memory were not detected by either solution. This is a potential hole that we felt was important to protect.”
Deployment of Invary's Runtime Integrity
With Invary’s Runtime Integrity deployed, the company now operates with continuous, independent assurance that the systems remain uncompromised.
“The install was very straight forward on both Linux and Windows systems.”
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.
Case Study Results:
Confidence in the security stack
Invary validates that detection tools are operating as intended, restoring trust in the telemetry the firm relies on for security decisions.
Verified system integrity
Continuous verification confirms that systems remain in a trusted state, preventing attackers from persisting undetected.
Force multiplier for a lean team
Automated integrity verification provides advanced assurance without requiring a dedicated SOC or additional analyst headcount.
Data protection & trust assurance
Verified system integrity strengthens the firm’s ability to safeguard data and prevent breaches, enhancing trust and reducing risk.
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.
About Invary
Invary provides continuous runtime integrity validation for Windows and Linux systems, detecting unauthorized changes that traditional security tools miss. By ensuring systems remain in a known and trusted state, Invary complements existing defenses, strengthens security posture, and helps organizations protect what matters most.
