What Is Cisco Secure Client Umbrella?

Modern enterprise security perimeters no longer stop at the office firewall. As hybrid workforces operate from home offices, branch sites, and public networks, securing endpoint internet connectivity requires protection that travels wherever users go. Cisco Secure Client (the evolution of Cisco AnyConnect) addresses this challenge by consolidating multiple endpoint services into a modular architecture. Among its most critical components is the Cisco Secure Client Umbrella Roaming Security module.

The Umbrella module extends cloud-delivered, DNS-layer protection and intelligent web proxying directly to corporate endpoints. By inspecting and securing connections at the earliest possible stage—the DNS lookup—it prevents users from connecting to malicious domains, command-and-control servers, and phishing sites before an HTTP or TCP session can even be established.

How the Cisco Secure Client Umbrella Module Works

The Umbrella Roaming Security module operates as a native plugin within Cisco Secure Client. It intercepts, evaluates, and protects outbound network requests transparently to the end user through a five-stage operational workflow.

Stage 1: Local Loopback DNS Interception

Once installed and registered, the module binds to the local loopback interface (127.0.0.1:53 on IPv4 and ::1:53 on IPv6). It overrides local adapter DNS configurations and intercepts every DNS query generated by system applications, browser sessions, and background services before requests leave the network interface card (NIC).

Stage 2: Encrypted Upstream Forwarding

The module bypasses standard, unencrypted local ISP or router DNS servers. Instead, it encapsulates queries and routes them to Cisco Umbrella Anycast resolvers (208.67.222.222, 208.67.220.220, and their IPv6 equivalents) over encrypted protocols:
* DNSCrypt or DNS over HTTPS (DoH): Uses UDP or TCP over port 443 to prevent man-in-the-middle tampering, eavesdropping, and ISP snooping.
* Standard DNS Fallback: If encrypted channels are restricted by an upstream firewall, queries fall back to standard UDP/TCP port 53 while preserving organization identity tags.

Stage 3: Real-Time Cloud Policy and Threat Inspection

When the query reaches the Cisco Umbrella cloud infrastructure, Umbrella evaluates the request against security policies configured in the management dashboard:
* Identity Attribution: Identifies the requesting endpoint using metadata embedded via the client’s configuration profile.
* Threat Intelligence Matching: Validates destinations against Cisco Talos threat intelligence feeds, which track malicious domains, fast-flux networks, ransomware infrastructure, and newly registered domains.
* Category Filtering: Evaluates acceptable use policies (such as blocking gambling, adult content, or peer-to-peer file sharing).

Stage 4: Policy Enforcement or Secure Web Gateway (SWG) Handoff

Depending on policy evaluation, Umbrella executes one of three outcomes:
1. Allowed Query: Umbrella returns the genuine IP address to the endpoint, allowing the application to connect normally.
2. Blocked Query: Umbrella returns the IP address of an Umbrella cloud block page, preventing the browser or service from reaching the threat.
3. Proxied / SWG Inspection: If the destination is deemed “risky” or if Secure Web Gateway (SWG) web policies are active, traffic is routed to the Umbrella cloud proxy for full SSL/TLS decryption, file sandboxing, and antivirus scanning.

Stage 5: Context-Aware Network Sensing

The module actively monitors network changes. When an endpoint connects behind an on-premises network already protected by an Umbrella Virtual Appliance (VA) or enters a corporate VPN tunnel, the module adapts dynamically. It steps back when protection is natively redundant and reactivates immediately upon returning to an untrusted off-network environment.

Cisco Secure Client Umbrella vs. Legacy Roaming Clients

Organizations often evaluate Cisco Secure Client Umbrella against earlier standalone agents or older AnyConnect releases. Cisco has officially retired the standalone Umbrella Roaming Client (URC) in favor of the unified Cisco Secure Client architecture.

Upgrading to Cisco Secure Client removes the operational overhead of running standalone agents while adding support for modern operating systems, hardware architectures, and unified endpoint policy enforcement.

Downloading the Cisco Secure Client Installer and OrgInfo.json

Deploying the Umbrella module requires two distinct assets: the core application package and an organization-specific profile definition.

Component Overview

1. Installation Archive: Contains the base deployment installers (MSI packages for Windows, PKG/DMG files for macOS) required to install Cisco Secure Client core services and the Umbrella module.
2. OrgInfo.json: A digitally signed metadata file generated by the Cisco Umbrella console that binds the installed module to your organization’s cloud tenant. It contains the unique organizationId, registration fingerprint, and administrator userId required for identity verification.

Dashboard Navigation Path

To acquire these assets from the Cisco Umbrella management interface:

1. Log in to the Cisco Umbrella Dashboard (dashboard.umbrella.com) using administrator credentials.
2. In the left navigation menu, expand Deployments (or Identities) and select Core Identities > Roaming Computers.
3. Click the + (Add) button or select the Roaming Client button at the top of the interface.
4. Locate the section labeled Cisco Secure Client (formerly AnyConnect) Umbrella Roaming Security Module.
5. Click Download Module Profile to download the OrgInfo.json file. Do not alter, rename, or edit the contents of this JSON file.
6. Select the download link for the Pre-Deployment Package corresponding to your target platform (Windows, macOS, or Linux). Alternatively, download the latest Cisco Secure Client installation image from the Cisco Software Central portal (software.cisco.com).

Step-by-Step Deployment and Configuration Guide

Enterprises can deploy the Cisco Secure Client Umbrella module across fleet endpoints using system imaging, Active Directory Group Policy (GPO), or Modern Device Management (MDM) tools like Microsoft Intune and Jamf Pro.

Step 1: Stage the Configuration Directory

The Umbrella module reads OrgInfo.json during the installation handshake to complete registration. The file must be placed in the designated path based on the endpoint operating system:

• Windows: %ProgramData%\Cisco\Cisco Secure Client\Umbrella\
• macOS: /opt/cisco/secureclient/umbrella/

When pre-staging via an installer folder, place OrgInfo.json in a subfolder named Profiles\umbrella\ directly adjacent to the installer files.

Step 2: Execute Mass Deployment via Command Line

To install silently without user disruption, run the installers in sequence using elevated administrative privileges.

For Windows (MSI Silent Execution):

Execute the core VPN framework first, followed by the Umbrella Roaming Security module:

msiexec /package cisco-secure-client-win-core-vpn-predeploy-k9.msi /qn /norestart
msiexec /package cisco-secure-client-win-umbrella-predeploy-k9.msi /qn /norestart

If staging the profile post-install via script, copy the downloaded JSON file to the working directory:

mkdir "%ProgramData%\Cisco\Cisco Secure Client\Umbrella"
copy /Y "OrgInfo.json" "%ProgramData%\Cisco\Cisco Secure Client\Umbrella\OrgInfo.json"

For macOS (Shell Script / MDM):

Extract the .dmg package and install the core framework alongside the Umbrella package:

sudo installer -pkg /path/to/Cisco_Secure_Client.pkg -target /
sudo mkdir -p /opt/cisco/secureclient/umbrella/
sudo cp /path/to/OrgInfo.json /opt/cisco/secureclient/umbrella/OrgInfo.json
sudo chmod 644 /opt/cisco/secureclient/umbrella/OrgInfo.json

Step 3: Configure Upstream Network Access

Ensure perimeter firewalls, proxies, and egress routers allow the endpoint to communicate with Cisco Umbrella resolvers over the required service ports:
* UDP & TCP Port 53: 208.67.222.222, 208.67.220.220
* UDP & TCP Port 443: 208.67.222.222, 208.67.220.220 (for DNSCrypt/DoH encryption)
* TCP Port 443 (HTTPS): Outbound to api.umbrella.com, sync.hydra.opendns.com, and registration endpoints.

Step 4: Verify Deployment and Identity Synchronization

Open the Cisco Secure Client desktop UI. Select the Umbrella tab and verify the status reports Protected. Next, return to the Cisco Umbrella Dashboard under Deployments > Core Identities > Roaming Computers and confirm the computer name appears in the registered identities inventory.

Troubleshooting Common Issues and Operational States

When deployment anomalies or network disruptions occur, the Cisco Secure Client tray interface displays diagnostic statuses. Here is how to diagnose and resolve the most common issues:

Why does the Umbrella module display a “Reserved” status?

Cause: The “Reserved” status indicates that the Umbrella engine is actively waiting for an operative network connection or is evaluating an interface change. This status appears transiently when the endpoint connects to a new Wi-Fi network, switches adapters, or establishes a VPN tunnel.
Resolution: Verify physical network connectivity. If the status remains stuck in “Reserved,” restart the Cisco Secure Client service (csc_vpnagent or vpnagent) or check whether local firewall software is completely dropping outbound interface traffic.

What causes an “Unregistered” or “Open” status?

Cause:
* Unregistered: The module is installed, but it cannot associate with an Umbrella dashboard organization. This occurs if OrgInfo.json is missing from the directory, contains corrupted JSON syntax, or contains an invalid user registration token.
* Open: The client has valid network connectivity, but outbound UDP/TCP queries on ports 53 or 443 to 208.67.222.222 are blocked by an upstream ISP or corporate firewall. In an “Open” state, the agent backs off and restores the system’s DHCP DNS servers to avoid dropping user internet access.
Resolution: Ensure OrgInfo.json is present in %ProgramData%\Cisco\Cisco Secure Client\Umbrella\ (Windows) or /opt/cisco/secureclient/umbrella/ (macOS). If testing for blocked ports, run an explicit lookup from the terminal:

nslookup opendns.com 208.67.222.222

If the command times out, permit outbound ports 53 and 443 in the local network router or firewall.

Why does the module report “Disabled (VPN Connection)” or “Disabled (Trusted Network)”?

Cause: Cisco Secure Client is context-aware.
* When a user initiates a full-tunnel VPN session, DNS resolution often routes directly to private corporate DNS servers behind the VPN headend. The Umbrella module steps back to allow the VPN tunnel to resolve internal domain resources without conflict.
* When on-premises behind an Umbrella Virtual Appliance (VA), the agent yields to the network-level VA to avoid double-processing queries.
Resolution: This is expected system behavior. If you require Umbrella cloud protection across a split-tunnel VPN, configure split-DNS policies in your AnyConnect/Secure Client profile to selectively forward internet-bound domains to Umbrella while preserving internal resolution.

How do I collect logs for Cisco TAC and deep debugging?

If unexpected DNS leaks or registration errors persist, generate a bundle using the Diagnostics and Reporting Tool (DART):
1. Launch Cisco Secure Client DART from the Start Menu or Applications folder.
2. Select Default bundle creation and include Umbrella module diagnostic logs.
3. The resulting compressed archive contains detailed operational traces from CiscoUmbrella_Roaming_Security.log and system network interface state tables for technical support review.
