Embedded Runtime Integrity

Sealing embedded software from any “after build” changes

Karamba XGuard:
A Completely Embedded
Security Suite

With the XGuard suite, the full image, OS, and application are protected against runtime modifications, preventing remote code execution attacks.

Patented, Automatic Runtime Integrity Foundation

Karamba software is deployed in the background during your product build process, without source code. By leveraging only the binaries, the software creates a “known good” base line which cannot be altered in the production environment. This foundation also provides the reporting infrastructure to detail the attack attempt and create the root cause analysis data that is needed for fast mitigation and patching.

Control Flow Integrity

In-memory attacks leverage memory corruption vulnerability to perform ROP and other code reuse attacks. With Karamba Control Flow Integrity the application identifies the unexpected memory utilization and can block and report the event. Our patented security solution also has a negligible impact on system performance.

Application Whitelisting

In dropper attacks, a self-contained malicious program, library, or script is added to the device and triggered to execute during runtime. Dropper attacks are commonly used as a follow-up to other exploitations, in order to execute the actual malicious behavior, or to establish a command and control channel.

Applying whitelisting is a strong protection against file traversal and other exploits but it is typically difficult to implement and maintain. Karamba Application Whitelisting provides an automatic way to deploy this defense mechanism without developer intervention and without any need to delay product release plans.

XGuard Embedded Runtime Security Advantages

ECU Protects Itself

Automatic Build

Requires zero developer intervention or updates during the software development lifecycle. Karamba XGuard fits into the current build tools and environment.

Zero False Positives

Strong Defense

Karamba XGuard does not fix buffer overflow, rather, it prevents hackers from exploiting it. Dropper and fileless attacks are detected in runtime, preventing the remote code execution attempt.

Supports all ECUs

Negligible Performance Impact

Optimized for embedded systems, the patented method enables runtime protection with less than 5% CPU overhead.

White Paper

What is autonomous security and how does it provide superior runtime integrity protection? In this white paper, we explain how deterministic methods harden the runtime environment to prevent system hacking.



Karamba’s platform features CFI, whitelisting, on-premise or cloud-based management, customizable reporting and forensics. Plus it’s easy to deploy, and supports almost any platform, build environment, and architecture.
