Find threats.
Investigate. Take action.

SNOW. Arc4dia’s threat investigation platform.

SNOW combines Arc4dia’s proprietary telemetry with other evidence and intelligence to support live threat hunting, investigation and authorized action on running systems. Live forensic analysis also helps uncover evidence of earlier compromises.

From behaviour and relationships
to an investigation you can act on

Bring available evidence together with backend analysis, deterministic automation and human-led investigation. The sources and agreed scope determine what can be established.

ACTIVE

Detect

Raise leads from suspicious behaviour, memory anomalies and covert execution indicators.

Icon

Investigate

Follow relationships over time, from remote access and observed AI-tool activity to processes and network connections.

REMOTE

Respond

Use the investigation to guide authorized response with your security team. Human review and response arrangements are agreed for each engagement.

Background

Why choose SNOW?

Connected evidence with investigation context

See the activity behind an alert, not just its label.

FOLLOW THE ACTIVITY

Keep context across processes, AI-tool activity and network relationships, wherever the evidence supports the link.

MEMORY EVIDENCE

Investigate in-memory anomalies and covert execution alongside the activity visible on disk.

CONNECTED INTELLIGENCE

Put observed activity in context with public exposure records and threat intelligence.

CONTROLLED ACTION

Gather the next piece of evidence and coordinate response within the permissions and scope agreed with your team.

See the activity behind AI tools

Coding agents launch shells, run scripts and interact with developer workflows. SNOW’s AI-agent module goes beyond recognizing a tool process: it groups observed activity into work sessions and keeps process lineage in context over time.

Relate that activity to the wider investigation, including remote access, child processes and network connections where the records support those links. Recognizing an AI tool is not the same as deciding its activity was approved.

SNOWboard

One investigation workspace

Review investigations, relationships and available evidence in SNOWboard. Endpoint-level detail depends on enrolled hosts and their telemetry; external intelligence keeps its own source and observation date.

Background

Put investigation evidence to work

Discuss what you need to see, which systems are in scope and how findings will reach your team. We can walk through the platform and the investigation workflow with you.
