Endpoint Application Control
Updated on October 25, 2022, by Xcitium
What Is Endpoint Application Control?
Endpoint application control is a security technology that manages which applications are allowed to run on endpoint devices such as laptops, desktops, servers, and virtual machines. It prevents unauthorized, malicious, or unapproved software from executing by enforcing predefined security policies based on allowlists, blocklists, digital signatures, or application reputation.
How Does Endpoint Application Control Work?
Endpoint application control continuously evaluates every application before it is allowed to execute.
The process typically includes:
- Identify applications installed on each endpoint.
- Compare applications against approved security policies.
- Verify digital signatures and file integrity.
- Allow trusted applications to run.
- Block or restrict unauthorized software.
- Monitor application behavior continuously.
- Alert administrators to policy violations.
- Update policies as business requirements evolve.
This approach reduces the attack surface and helps prevent malware, ransomware, and unauthorized software execution.
Endpoint Application Control vs Antivirus
| Endpoint Application Control | Traditional Antivirus |
|---|---|
| Controls which applications can run | Detects known malware |
| Prevents unauthorized software execution | Primarily blocks malicious files |
| Uses allowlisting and policy enforcement | Often relies on signatures |
| Reduces attack surface | Focuses on malware detection |
| Stops unknown applications by default | May allow unknown software until detected |
Application control complements antivirus by preventing unapproved applications from running, even if they are previously unknown.
Allowlisting vs Blocklisting
| Allowlisting | Blocklisting |
|---|---|
| Only approved applications can run | Only known malicious applications are blocked |
| Default action is deny | Default action is allow |
| Stronger protection against unknown threats | Easier to deploy initially |
| Recommended for high-security environments | Suitable for general protection |
| Supports Zero Trust strategies | Less effective against new threats |
Many organizations use a combination of both approaches depending on operational requirements.
Fast, flexible and scalable protection against zero-day and advanced persistent threats
There are multiple routes for unknown code to execute on a host CPU, and Application Control provides a key tool in controlling unknown, potentially bad, applications from executing. Application Control provided by Xcitium Advanced Endpoint Protection (AEP) blocks unauthorized executables on servers, corporate desktops, and fixed-function devices. Using a dynamic trust model and innovative security features such as local and global reputation intelligence, real-time behavioral analytics, and auto-immunization of endpoints, it immediately thwarts advanced persistent threats—without requiring labor-intensive list management or signature updates.
- Complete protection from unwanted applications with coverage of executable files, libraries, drivers, Java apps, ActiveX controls, scripts, and specialty code.
- Flexibility for desktop users and server admins with self-approval and auto-approval based on application rating.
- Viable security for fixed-function, legacy, and modern systems.
- Patch cycle reduction and advanced memory protection.
- Centralized, integrated management via the IT & Security Manager.

Thwart threats with intelligent whitelisting
Reduce risks from unauthorized applications and code
Know the reputation of every file and application in your environment and categorize them as good, bad and unknown with real-time Valkyrie file analysis
Leverage three options to maximize their whitelisting strategy
Default Deny allows software execution based on an approved whitelist or authorization by trusted channels. Detect and Deny allows software execution through signature-less reputation verification, and Verify and Deny allows the execution of applications that are verified by sandbox testing.
Save time and lower costs
Eliminate the need for signature updates or labor-intensive list management, and using a dynamic trust model that requires negligible CPU and memory usage.
Reduce patch cycles and protect memory
Maintain your regular patch cycles and prevent whitelisted applications from being exploited via memory buffer overflow attacks on Windows 32- and 64-bit systems.
Protect legacy systems and modern IT investments
Protect older operating systems, such as Microsoft Windows NT, 2000, and XP as well as recent operating systems such as Microsoft Windows 10.
Xcitium Advanced Endpoint Protection (AEP) provides visibility and control over what applications users are installing on endpoints, both desktop/laptop and mobile. Further, Windows applications can be set to run, be blocked or run only inside the secure container. Non-critical business applications can be blocked from running entirely.
- Desktop/Laptop –. As the world’s largest Certificate Authority, Xcitium enjoys the advantage of providing unique insight into known good applications, software publishers and even OS level processes. This knowledge is used in determining the ‘known good’ as well as generating an accurate listing of all known bad applications or files. This unique compilation of known good and known bad allows your users to run trusted applications with confidence.
- Mobile – Xcitium Advanced Endpoint Protection allows administrators to view all applications installed on enrolled Android and iOS devices and block any malicious applications that are identified. Administrators to view the list of applications identified on all enrolled mobile devices and review their trustworthiness.

How to Implement Endpoint Application Control
Follow these best practices:
- Inventory all endpoint devices and applications.
- Identify business-critical software.
- Create an approved application allowlist.
- Configure trusted publisher rules.
- Enable audit mode to evaluate existing software usage.
- Gradually enforce application control policies.
- Monitor policy violations and endpoint activity.
- Update allowlists as business needs change.
- Integrate with endpoint detection and response (EDR).
- Review and optimize policies regularly.
A phased implementation minimizes business disruption while improving security.
Why Endpoint Application Control Supports Zero Trust
Endpoint application control strengthens Zero Trust by:
- Verifying every application before execution.
- Enforcing least-privilege principles.
- Preventing unauthorized software.
- Reducing lateral movement opportunities.
- Limiting attack surfaces.
- Supporting continuous verification.
Application control ensures that only trusted software operates within the environment.
