Threat Exposure Management
Attack Surface Management
Asset discovery and review help teams maintain a clearer inventory and direct remediation toward relevant exposure.
- Discovery of internet-facing assets
- Review and prioritization of exposures
- A clearer, maintained asset inventory
- Remediation directed toward relevant exposure
The challenge
Changing ownership hides internet risk
Teams cannot prioritize internet risk when ownership and exposure keep changing. Attack surface management creates a repeatable view of public assets, then adds ownership and risk context so remediation reaches the right team.
A maintained view of external exposure
Public services change as teams launch applications, move infrastructure or work with suppliers. Asset inventories often lag behind that change, leaving unknown or forgotten systems outside routine maintenance.
Cyberus supports recurring discovery, validation and prioritization of internet-facing assets. Findings become useful when they are matched to an owner, confirmed as relevant and tracked through an agreed remediation workflow.
From unknown asset to owned fix
- Outside-in discovery. Candidate domains, hosts and services are found from the same view an outsider would have.
- Association check. Each candidate is confirmed as yours, a supplier asset or unrelated before anyone acts on it.
- Named owner. A responsible team is recorded so a finding has somewhere to land and someone to act.
- Tracked remediation. Fixes and retired assets are followed on the agreed cadence so the inventory stays usable.
Why it matters
- Business risk: Forgotten or unowned public systems stay outside patching and review, so nobody notices when they become an easy way in.
- Decision it supports: Leaders can decide which exposed assets to fix, retire or hand to a named owner, instead of treating every finding as equal.
- What you receive: You receive a validated inventory of in-scope public assets with owners and a ranked list of exposures to work through.
Turn discovery into owned work
Scheduled review cadence
Continuous or recurring review applies only to the cadence, assets and reporting set out in the written scope agreed before work starts.
- Why it matters
- Without a stated cadence, review drifts into a one-off exercise that goes stale as teams launch and move services.
- Supports
- Agreeing how often assets are rechecked
External asset discovery
Identify domains, hosts, services and certificates related to the agreed organization scope.
- Why it matters
- You cannot protect or patch a system nobody knows is public, so discovery sets the ceiling for everything after it.
- Supports
- A starting inventory of public assets
Ownership validation
Separate relevant assets from third-party or unrelated infrastructure and identify internal owners.
- Why it matters
- Alerts about assets that are not yours waste effort, while real assets with no owner never get fixed.
- Supports
- Assigning each asset to an accountable team
Exposure review and contextual prioritization
Assess reachable services, weak configurations and signals that warrant deeper investigation. Consider asset purpose, sensitivity, reachability and ease of remediation rather than severity alone.
- Why it matters
- Reachable services and weak settings show where an outsider could start, which helps you target limited review time. A low-severity issue on a sensitive system can matter more than a high-severity one on a test box.
- Supports
- Choosing which exposures need deeper testing; ordering remediation by business context
Change tracking
Review newly observed and retired assets on an agreed cadence to keep the inventory useful.
- Why it matters
- New and retired assets show how fast your footprint is changing and where inventory habits are failing.
- Supports
- Spotting drift between reviews

Frequently asked questions
Is the review continuous?
The cadence is whatever the written scope specifies, for example scheduled reviews of agreed domains and ranges. It is not an availability claim, and discovery cannot be assumed to be complete.
Will discovery find assets missing from our inventory?
That is one purpose of the service, but every candidate asset still needs validation before it is treated as belonging to the organization.
Is this the same as penetration testing?
No. Exposure management provides recurring breadth and change awareness. Penetration testing provides deeper, time-bounded validation against an authorized scope.
How are findings prioritized?
Priority can consider reachability, asset purpose, data sensitivity, exploitability, existing controls and the effort needed to remediate.
