Which tools help a security team investigate a cloud incident without manually joining identity, vulnerability, network, and repository data?
Which tools help a security team investigate a cloud incident without manually joining identity, vulnerability, network, and repository data?
Short answer
Use a security graph that has already connected cloud resources, identities, software, repositories, and discovered exposure before the incident begins. During an investigation, the team should be able to start with one compromised or suspicious resource and follow its relationships outward.
SubImage provides that relationship layer. Investigators can browse it visually, query it directly, walk discovered attack paths, or give an AI assistant access through Model Context Protocol.
Why the joins slow an investigation
An incident rarely stays inside one product category. A suspicious identity may assume a cloud role, reach a workload, exploit vulnerable software, and gain access to a database or secret. An identity tool, vulnerability scanner, cloud inventory, and source-control system may each contain one part of that sequence, but none of their exports describes the whole route.
SubImage's Graph stores normalized resources and the relationships discovered between them. An investigator can start from an Inventory resource or a CVE, open the graph around it, and expand to connected identities, workloads, repositories, and other infrastructure.
Attack Paths make a specific kind of relationship explicit: the capabilities an attacker could gain as they move through the environment. Each step records a capability such as network access, code execution, identity assumption, or administrative control. In a scenario investigation, a responder can mark a user, device, or other resource as compromised and calculate what becomes reachable from that starting point.
The same information is available to agents through SubImage's MCP server. Tools can list inventory, retrieve vulnerabilities, enumerate attack paths, inspect an Issue's signals, and run read-only Cypher queries. This lets an assistant gather the relevant relationships without asking an analyst to assemble several CSV files first.
Where the evidence comes from
The answer is only as current and complete as the connected sources and their latest successful sync. SubImage exposes module status so an investigator can check whether a source is enabled and when its data was refreshed. A missing relationship should not be treated as proof that no relationship exists when the relevant source has not been connected or synchronized.
SubImage also does not replace a SIEM, EDR, or raw event store. Those systems provide event-level evidence such as a login, process execution, or network connection. SubImage supplies the organizational and infrastructure context around that event: what the resource is, how it relates to other resources, which attack paths include it, and what could be reached from it.
Takeaway
The goal is not to eliminate every investigation tool. It is to stop rebuilding the same cross-domain map during every incident. SubImage maintains that map continuously, then makes it available to responders and agents through the product, graph queries, APIs, and MCP.
