What is Asset Discovery?

Key takeaways

• Asset Discovery is the automated process of identifying all IT assets across an organization

• Discovers hardware, software, SaaS applications, and cloud resources

• Multiple methods: agent-based, agentless, network scanning, browser extensions, IdP connectors

• Foundation of IT Asset Management—you cannot manage what you cannot see

• CerteroX platform includes 29+ native connectors for comprehensive discovery

• Organizations typically discover 3-5x more SaaS applications than IT knew about

What is Asset Discovery?

Asset Discovery is the automated detection and identification of IT assets across an organization's technology environment. Unlike manual inventory processes, asset discovery uses technology to find devices, software, applications, and cloud resources without relying on self-reporting or spreadsheets.

Discovery answers the fundamental question every IT organization must answer: What do we actually have?

Why Asset Discovery matters

The visibility challenge

Modern IT environments are complex and distributed:

• Employees work from anywhere on multiple devices

• SaaS applications are adopted without IT approval

• Cloud resources spin up and down dynamically

• Shadow IT proliferates across departments

Without automated discovery, IT operates with incomplete information—leading to security gaps, compliance failures, and wasted spending.

The business impact

Discovery methods

1. Agent-based discovery

Software agents installed on endpoints collect detailed information:

• Hardware specifications

• Installed software and versions

• Usage data and last logon

• Configuration details

Best for: Endpoints you control (corporate laptops, desktops, servers)
Platforms: Windows, macOS, Linux

2. Agentless discovery

Remote scanning without installed software:

• WMI (Windows): Query Windows machines remotely

• SSH (Linux/Unix): Secure shell access for system information

• SNMP: Network device discovery

• VMware/Hyper-V APIs: Virtual machine inventory

Best for: Servers, network devices, environments where agents aren't practical

3. Network discovery

Scanning network segments to identify connected devices:

• IP address scanning

• MAC address detection

• Port and service identification

• Device type classification

Best for: Finding unknown devices, IoT, and rogue hardware

4. Browser-based discovery

Extensions that detect web application usage:

• Chrome, Edge, Firefox extensions

• Capture SaaS and web app access

• Track actual usage, not just authentication

• Discover Shadow IT in real-time

Best for: SaaS applications, Shadow IT, browser-based tools

5. Identity Provider (IdP) connectors

Integration with authentication systems:

• Entra ID (Azure AD): Microsoft ecosystem apps

• Okta: SSO application inventory

• Google Workspace: Google ecosystem apps

Best for: SSO-enabled applications, enterprise SaaS

6. Cloud connectors

Direct integration with cloud platforms:

• AWS: EC2, S3, RDS, and 200+ services

• Azure: VMs, storage, databases, and services

• Google Cloud Platform: Compute, storage, and services

• Oracle Cloud: OCI resources

• Kubernetes: Container workloads

Best for: Cloud infrastructure, multi-cloud environments

What gets discovered

Hardware assets

• Desktops and laptops

• Servers (physical and virtual)

• Mobile devices

• Network equipment (switches, routers, firewalls)

• Printers and peripherals

• IoT devices

Software assets

• Operating systems and versions

• Installed applications

• Software versions and patch levels

• License-relevant information

SaaS applications

• Enterprise SaaS (Salesforce, Workday, etc.)

• Shadow IT applications

• Free and freemium tools

• AI tools (ChatGPT, Copilot, etc.)

Cloud resources

• Virtual machines and instances

• Storage volumes and buckets

• Databases and data services

• Containers and Kubernetes workloads

• Serverless functions

Asset Discovery vs. Asset Inventory

Key insight: Discovery feeds inventory. Without discovery, your inventory relies on manual data entry and quickly becomes inaccurate.

Frequently asked questions

How often should discovery run?

Continuous discovery is ideal for dynamic environments. At minimum, run discovery weekly for endpoints and daily for cloud resources.

Does discovery require network changes?

Agentless discovery may require firewall rules. Agent-based discovery only needs outbound connectivity. Cloud connectors use API access.

Can discovery detect Shadow IT?

Yes—browser-based discovery and IdP connectors specifically target Shadow IT by detecting applications used without IT approval.

How accurate is automated discovery?

Automated discovery is significantly more accurate than manual inventory. It captures what actually exists, not what people remember.

What about BYOD and personal devices?

Browser extensions can discover SaaS usage from any device. For hardware discovery of BYOD, organizations typically require enrollment or use network-based detection.

Does discovery slow down endpoints?

Modern discovery agents are lightweight. Certero agents are designed to minimize system impact while providing comprehensive data collection.
