Overview
A Network Security Policy in Zaperon allows administrators to control and secure web traffic and application behavior across users and devices. By defining rules such as allowed/blocked domains and application-level controls, organizations can prevent unauthorized access, reduce attack surface, and enforce secure usage policies.
These policies are essential for implementing Secure Web Gateway (SWG) and Zero Trust security, ensuring that only trusted applications and destinations are accessible.
Why Create a Network Security Policy?
Creating a Network Security Policy helps organizations:
Control access to websites and cloud applications
Prevent unauthorized or risky application usage
Enforce URL filtering and domain restrictions
Block malicious or non-business applications
Protect against phishing, malware, and data exfiltration
Restrict application connectivity at a granular level
Strengthen Zero Trust enforcement across endpoints
Why Create a Network Security Policy?
You should create a policy when:
You want to block or allow specific domains
You need to control application-level network access
You want to restrict specific processes or apps (e.g., Discord, Teams)
You need to enforce secure browsing + app usage together
You are implementing Zero Trust access controls
When to Create a Network Security Policy?
Create a Network Security Policy when you need to enforce controlled and secure internet and application access across your organization.
This typically applies when:
Users are accessing unrestricted internet, increasing security risks
You want to block malicious or non-business websites
Employees are using unauthorized applications (shadow IT)
You need to enforce application-level restrictions (e.g., WhatsApp, Telegram, Discord, torrents, etc)
You want to control both browser traffic and background app traffic
Sensitive data needs protection from unauthorized uploads/downloads
You are implementing a Zero Trust security model
You need centralized control over user web and app activity
Creating a New Network Security Policy
1. To create a policy, go to Network Security and click on Create Policy button.
2. Enter all the basic info and click Next.
3. In Application Control tab, Select app control type you want to block or allow. you can choose predefined applications or process name from the dropdown and click Next.
Predefined Apps – Choose apps from a list of zaperon defined applications you want to block or allow.
Process Name – Define process name for the application you want block or allow.
4. In Web Filtering tab, Select web categories you want to block or specify domains you want to allow or block access or define control actions to cloud apps (Upload, Download, Delete) and click Create.
You can create 4 types of restrictions by expanding sections:
Blocked Categories – Select categories of URL which you want to block.
Allowed Domains List – Define list of domains which are allowed for user by clicking Add Domain.
Blocked Domains List – Define list of domains which are blocked for user by clicking Add Domain.
Cloud Protection – Select application, application tag and blocked operation to protect cloud data. To create an application event, Refer to this section.
5. On successful creation of policy, confirmation message will appear.
6. New policy created will appear in the policy list.
Managing DLP Policy
After creating a policy, administrators can:
Enable or disable policies
Edit application and domain rules
Update process-based controls
Delete policies when no longer required
→ Refer to Manage Network Security Policies
Summary
Zaperon’s Network Security Policy enables organizations to enforce both web-level and application-level controls from a single interface. With the addition of Application Control, administrators can now restrict or allow applications at a granular level, ensuring stronger security, reduced risk, and full alignment with Zero Trust principles.
