How Does AppGuard Work?

This short video explains how AppGuard blocks all malicious malware on endpoints and servers.

AppGuard is delivered and supported in UK and Europe via Assurity Systems Ltd.

A New Approach to the New World of Cyber Threats

Originally developed for the US intelligence community and now protecting millions of endpoints, AppGuard adopts a fundamentally different approach to cyber security than that offered by the traditional antivirus/ malware/ ransomware providers.

As opposed to “detect and repair”, AppGuard has a zero-trust policy which prevents any harmful programme from executing – so no matter what known or unknown threats that are introduced to your network – they do no harm.

Furthermore, (and again in contrast to other providers), AppGuard has such a light footprint that it has virtually no impact on your device memory or CPU, requires almost no updating and no user interaction.


Zero Trust

AppGuard’s patented Inheritance Technology maintains the same level of guarding and isolation on any process spawned from a risky application – no matter how trustworthy they appear to be.

True Autonomy

AppGuard’s technology does not rely on detection and response, it instead prevents. It requires no updates, no connection to a central server – reducing human error and workload for IT.


AppGuard is less than 1MB on the endpoint, takes just days to deploy, does not scan files, causes zero degradation of speed at the endpoint, and drastically reduces operating costs.

AppGuard prevents all non-policy conforming processes at the kernel level.

AppGuard’s patented technology prevents viruses, fileless malware, botnets, polymorphic malware, weaponized documents, targeted attacks, in-memory attacks, ransomware, phishing, watering-holes, drive-by-downloads, and other undetectable advanced threats.

AppGuard stops attacks at the initial stages and beyond without requiring detection of the attack, without disrupting the user experience, or degrading system performance. AppGuard has the lightest footprint in the Endpoint category – by a wide margin. It scales to over 100,000 endpoints and provides a central management architecture that is simple,elegant, and cloud efficient.

AppGuard generates valuable Indicators of Attack (IOA) alerts without a compromise occurring.

AppGuard is compatible with all Windows versions from XP to 10, standard and custom applications, typical system maintenance tools, and supports Windows Server 2008 R2 and above.

With AppGuard breaches are stopped before detonation. 

“AppGuard should be on every Windows system in the world.”

Former Chief Information Security Officer
Central Intelligence Agency (CIA)

“AppGuard has a completely new method for delivering threat protection and breach prevention. I’m a true believer, and that’s why I’ve joined the AppGuard team.”

Current Chief Strategy Officer, AppGuard

AppGuard’s patented technology is the only security product in the marketplace that is currently undefeated by any kind of malware.

It doesn’t depend on detection methods and scanning used by traditional anti-virus software. Instead, it allows your systems to operate normally and prevents endpoint breaches before they can occur. This means your systems will always be protected from both known and more importantly, unknown threats

No Update Ever Needed

AppGuard disrupts malware attacks at their earliest stages. This ensures that breach attempts are halted before a compromise can occur without the need for detection, scanning, or updates. Our technology does not require constant updates or the need to build lists of known security threats already identified by other sources. Our integrated software only approach is seamless with all Microsoft Windows platforms, stands alone with no OS hooks, and includes all documented APIs.

No CPU Degradation

AppGuard carries an extremely light footprint with no processor dependency and minimal system resource requirements. Your endpoint systems will maintain maximum performance while always being protected. 

With a light footprint, no updates, no default deny functionality, nor any detection based functionality, AppGuard is transparent to the end-user and creates an efficient management function that is less resource intensive then even legacy anti-virus platforms. 

No User Interaction Required

Once AppGuard is installed, no user interaction is required. AppGuard does it all for you, completely autonomously. 

Prominent industry analysts have recognized AppGuard as a leading next generation solution for endpoint protection. AppGuard won the Government Security News (GSN) Homeland Security Award  for 2014, 2015 and 2016 for Best Anti-Malware Platform, as well as the 2016 American Security Today (AST) Platinum Award for Best Cyber Anti-Malware Solution. In addition to those awards, the US Army recognized the effectiveness of AppGuard by granting it a Certificate of Net Worthiness in 2017.
