1. What is Runtime Integrity, and why do I need it?
Chevron up
Prevailing security solutions assume trust in operating systems, yet are unable to verify their integrity, allowing malware hidden in the OS to deceive them (Drovorub for example).  Invary believes that Zero Trust should be expanded to include the OS as an entity, and removing assumptions about it are vital to a comprehensive Zero Trust Architecture.  

Invary’s approach to Runtime Integrity closes this Zero Trust gap and is based on IP invented by the NSA. Utilizing this foundation, Invary’s Runtime Integrity service validates that operating systems are behaving according to the invariants defined in their code. In essence, Invary validates that an entire system is “good”, instead of employing techniques used by prevailing XDR and EDR solutions that inspect individual aspects of a system for the presence of “bad”.   By re-establishing faith in the operating system, we enable our customers to regain confidence in their security posture. 
2. How is Invary different from other Runtime Integrity solutions?
Chevron up
Invary's approach to Runtime Integrity is built on unique intellectual property developed by the NSA, which enables our technology to provide a higher level of assurance than traditional runtime integrity services that use simple techniques like hashing. Unlike these services, Invary's technology is designed to understand the complex structure and interactions of a kernel at runtime, and to validate that the system is behaving within its intended invariance as defined by its underlying code.

What's more, our approach is non-intrusive and does not require the installation of any extraneous kernel modules or customized kernels. We recognize that your systems are performing critical tasks with demanding performance requirements, so our software is designed to operate with minimal impact on your workloads.

With Invary, you can be confident that your system is functioning exactly as intended, and that it is protected from a wide range of potential threats, without compromising your system's performance or stability.
3. How does Invary work?
Chevron up
Invary validates the Runtime Integrity of operating systems by efficiently taking measurements of your virtual or physical machines with the Invary Sensor at runtime then appraising those measurements against a predefined known good baseline on the Invary platform.   Check out this video to learn more
4. What services do you offer?
Chevron up
Invary offers two services:  

Our flagship Runtime Integrity Service provides advanced continuous protection of your operating systems, and retains a history of your system’s integrity.  It offers notifications of failed integrity appraisals as well as an API and Webhook to integrate our intelligence & alerts into your SIEM or monitoring solution.  

Our Runtime Integrity Score service allows you to spot check the Runtime Integrity of any system for free, providing a one-time appraisal.
5. What type of malware does Invary detect?
Chevron up
Invary detects malware that changes the Runtime Integrity, or intended behavior, of your operating systems, and prevents them from undermining the rest of your security stack. Invary’s technology makes it possible to identify novel zero day attacks or attacks generated by AI because Invary focuses on validating intended behavior and has no need to “learn” new malicious behaviors before identifying them.

6. Does Invary require time to train on, or learn, my environment? 
Chevron up
No, Invary can appraise your operating systems immediately and provide you with a clear and accurate view of your Runtime Integrity.  
7. Does Invary work in my virtual or cloud native environment? 
Chevron up
Invary was designed for cloud native environments and runs on all major cloud platform providers including AWS, GCP, and Azure. In addition Invary supports both type 1 and type 2 hypervisors.  
8. What Linux distributions and kernel versions do you support? 
Chevron up
Invary currently supports the following x86-64 distributions:

AWS Linux 2 and 2023 
CentOS 7 and 8 
Debian 9, 10, 11, and 12
Red Hat 7, 8, and 9
Rocky 9.x
Ubuntu LTS releases 18.04, 20.04, 22.04, 22.10, 23.04

Invary supports most kernels. Invary advocates you stay up to date on installing the latest kernels, and typically adds support for new kernel releases the same day.  Invary is continually adding support for additional distributions.

If you have a distribution or kernel that you wish to be supported please contact us at [email protected].
9. Does Invary support Windows? 
Chevron up
Invary is currently working on a version that supports Windows. For more information contact us at [email protected] 
10. How long does it take Invary to measure a system?
Chevron up
Measurements typically take less than 10 seconds, and your appraisal is ready seconds after that.  Times may vary depending on the size and load of your system. 
11. What does the Invary sensor measure, and why does it require superuser access?
Chevron up
Invary utilizes sophisticated algorithms to generate a detailed graph that accurately represents the current state of your system, including kernel data structures and their interdependencies. It's important to note that Invary is designed as a read-only service and does not modify, collect or store any of your personal data.  For more details please read our measurement specification
12. Does Invary impact my machine’s performance?
Chevron up
Invary is designed for seamless operation with minimal performance impact on virtual and physical machines, across cloud-native, hybrid, and on-premises environments.  
13. Is Invary’s Sensor open source?
Chevron up
We are in the process of open sourcing the Invary Sensor, and expect to publish it in Q3 2023.  
13. Why does Invary appraise measurements on the Invary Platform?
Chevron up
To ensure the accuracy and reliability of its appraisals, Invary compares each measurement against a baseline stored in our inventory of pre-captured baselines. These baselines are generated from a wide range of distributions and kernel versions. By drawing on this diverse inventory, Invary can identify even subtle deviations from the norm and provide you with a more thorough and comprehensive appraisal of your system's integrity.  
13. How do I deploy the Invary Sensor and how does it work?
Chevron up
See the Invary Sensor Guide for details. 
13. How do I integrate Invary into my security stack?
Chevron up
Invary’s Runtime Integrity Service offers a webhook to stream Runtime Integrity events to your system of choice.  Invary also offers an API to pull appraisals and endpoint information.  See our developer guide for more information
13. What authentication methods does Invary support?
Chevron up
Invary’s Runtime Integrity Service supports: Invary authentication, Google authentication, or OIDC.
