For approximately 100 PCs, the implementation period is around one month.
For about 10 servers, it typically takes around three months.
However, the actual schedule may vary depending on several factors such as the number of PCs and servers, your network environment, and the number of installation sites.
We will propose a detailed implementation schedule after discussing your specific requirements.

Yes, it can. It is designed to complement existing antivirus solutions, as well as post-incident response products, such as EDR and XDR. It can be used alongside these products without conflict.

At this time, AppGuard is available only for Windows OS.

This varies by product and retailer, so please contact us for details.

The biggest difference lies in the criteria used to identify threats. Detection-based security products monitor system behavior using AI and behavioral analysis to determine whether an activity is malicious, and then take action accordingly.
In contrast, AppGuard does not make such judgments. It enforces a rule that allows only “authorized and safe system commands” to execute; everything else is automatically blocked.
To put it simply, detection-based security is like a police car patrolling the roads and responding to rule violations after detecting them. AppGuard, on the other hand, is like the rails of a train — the system can only run on predetermined, safe tracks. The system remains unaffected—even by sophisticated attacks that can deceive AI—because AppGuard prevents any “derailment” by design..

Because AppGuard doesn’t focus on the attacker’s methods—such as malware type or exploited vulnerabilities—but instead blocks their ultimate objective of executing unauthorized commands, it has never been breached since its launch.
No matter how new or sophisticated a threat is, the number of actions required to carry out an attack successfully is limited.
AppGuard prevents these critical actions at the core of the system itself. As a result, the concept of 'falling behind new threats' simply does not apply to AppGuard.

AppGuard is ideal for organizations — regardless of industry — that are facing the limitations of traditional security measures, such as systems that are difficult to patch or attacks that are hard to detect.
With its innovative “Hardening” approach, AppGuard addresses these deep-rooted challenges at their core and ensures the continuity of your business operations.

Yes, it can. AppGuard is evaluated based on the importance of the assets that need protection, not the number of PCs or servers.
Even in small environments, if you have critical systems, such as servers that support core business operations or PCs that cannot be updated, AppGuard’s Hardening approach offers an optimal solution to ensure their protection.

AppGuard is designed to prevent malicious actions rather than identify threats by their signatures. Even the latest threats must issue a common set of system commands to achieve their objectives.
AppGuard blocks these essential commands at the core of the system, rendering even unknown threats powerless — all without the need for definition files or pattern updates.

Unlike detection-based products, AppGuard does not trigger emergency alerts such as “An attack has been detected.” Instead, AppGuard simply prevents the malicious command from executing at the moment the attacker attempts it.
As a result, the attack fails in its very first step — long before it can become an incident — and the system continues operating safely as if nothing had happened. While the blocking event is recorded in the log, there is no need for incident response or recovery efforts.

Antivirus and EDR solutions play an important role as detection and response layers in cybersecurity. AppGuard does not replace them —instead, it adds a new layer of “Hardening”, completing a truly multi-layered defense. To illustrate: if AV and EDR act as security guards who detect and respond to intruders, AppGuard serves as the architectural rule of the building itself, ensuring that even if an intruder gets inside, they cannot carry out any malicious actions. Combining AppGuard with detection-based solutions builds a last line of defense that addresses blind spots in traditional detection technologies, creating a far more resilient security posture..

AppGuard is not designed to replace other security products. Since it can coexist with virtually any solution and strengthen your overall defense layers, how you use it depends on your security strategy priorities.

1. If your top priority is preventing incidents before they happen: AppGuard alone provides the most robust protection with minimal operational burden — a defense that does not rely on detection. It specializes in neutralizing threats before they occur, including unknown attacks and those that exploit legitimate tools.

2. If you aim to balance "prevention" with "detection and visibility": AppGuard can be used alongside your existing NGAV or EDR solutions. By blocking the vast majority of attacks in advance, AppGuard dramatically reduces noise within your EDR environment. This allows your team to focus only on critical threats, thereby maximizing the value of your existing security investments.
