SIEM Enrichment: Add Context
at Ingest, Not After the Alert

Most SIEMs look up context after something fires, when IPs have been reassigned and the trail has gone cold. Aleph enriches every signal the moment it arrives, so detections, investigations, and AI work with the full picture.

What is SIEM enrichment?

SIEM enrichment is the process of adding context to raw security events: who the user is, what the asset does, whether the IP is known-bad, where the connection came from. An enriched event answers those questions on its own. A raw event only raises them.

At query time the traditional way

The SIEM stores raw events. When an alert fires, an analyst or an automation looks up context in other tools. Every investigation repeats the same lookups, and the answers describe now, not the moment the event happened.

At ingest the Aleph way

The pipeline parses and enriches events in stream, before they are stored. Context is captured while it is still true and becomes part of the event itself. Detections, searches, and AI all inherit it for free.

Context that arrives late is context you can't trust

Ever pivoted through four consoles to answer "is this IP even ours?" That lookup tax is the query-time model at work, and it costs more than time.

Context decays fast

Cloud IPs get reassigned in minutes. Users change teams. Containers live for an hour. A lookup done during the investigation describes today's environment, not the one where the event happened.

Analysts pay the same tax twice

The same user, asset, and intel lookups get repeated in every investigation, by every analyst, for every alert. None of that work makes the next alert any faster.

Detections run blind

A rule that only sees a raw event can't tell an admin's expected login from an attacker's. That gap is where false positives come from, and where real attacks hide.

How Aleph enriches at ingest

1

Collect and parse

Events stream in from your stack and are parsed into a clean, consistent schema at the edge.

2

Enrich in stream

Aleph joins each event with identity, asset, threat intelligence, and business context in real time.

3

Store enriched

Events land in your data lake with their context attached, searchable and ready for investigation.

4

Detect and act

Detection rules and AI investigation run on enriched events, with the full picture from the first millisecond.

What context gets added

Identity

Who is behind the event: the user, their role, their team, and whether the login fits how they normally work.

Asset

What the machine is: owner, environment, criticality, and exposure, pulled from your asset inventory.

Threat intelligence

Whether the indicator is known-bad, which campaigns it belongs to, and who else has seen it.

Location and network

Where the connection came from, what network it crossed, and whether that path makes sense.

History

What this user or asset did before, so a single event becomes part of a pattern instead of a data point.

SIEM enrichment questions, answered

What is the difference between SIEM enrichment and correlation?

Correlation links events to each other. Enrichment adds outside context to each individual event. They work best together: correlation rules running on enriched events can match on user, asset, and intel fields that raw logs simply don't have.

Doesn't enriching every event increase storage costs?

Enriched fields add little on top of compressed raw events, and the economics favor it: storage is cheap, analyst time is not. Aleph customers see around 80% lower total SIEM cost than legacy platforms, because enrichment happens once in the pipeline instead of over and over in investigations.

Can I enrich events I have already stored?

Yes. Aleph keeps a full backup of your raw events and can re-stream them through the pipeline, so historical data can be enriched, re-parsed, or replayed against new detections at any time.

Which sources does Aleph use for enrichment?

Your identity provider, asset inventory, cloud platforms, threat intelligence feeds, and the rest of your connected stack. Aleph ships with integrations for the common sources and lets you add your own business context.
