ROOTKey vs SIEM: do I need both?

ComparisonSIEM · ROOTKeyEvents through the REST API and webhooks

Short answer

A SIEM collects and correlates the logs and security events your systems produce, so your team can detect and investigate suspicious activity. ROOTKey works on the data itself: it seals a fingerprint of every version of your files, tables and records, catches any change - what, who, when and where - and restores only what was altered. Your SIEM detects events; ROOTKey answers which data can still be trusted after an alert. If you need both answers, you need both, and ROOTKey's events reach your SIEM through the REST API and webhooks.

Side by side: SIEM and ROOTKey

A SIEM looks at the events your systems report. ROOTKey looks at the content of your files, tables and records. The table sets out what each one does.

When you need each

SIEM
To monitor activity across many systems, correlate events, raise alerts and support your security operations team when it investigates an incident.
ROOTKey
When the question is about the data itself: whether a file, table or record was changed, exactly what changed, which version can be trusted, and how to prove it to an auditor or a regulator.

They answer different questions and work best together.

How they work together

ROOTKey's events are available to your SIEM through the REST API and webhooks, so your team sees changes to the data alongside the rest of its security events.

  1. Anchor

    Every version of every file, table or record gets a unique fingerprint, sealed in an independent public registry with a timestamp.

  2. Detect

    ROOTKey continuously compares your data with the sealed record and raises an alert on any modification, explained: what, who, when and where.

  3. Correlate

    The events reach your SIEM through the REST API and webhooks, next to the events from the rest of your infrastructure.

  4. Recover after an alert

    When an alert fires, ROOTKey shows which data was altered and which can still be trusted, and restores only what was altered to the last version proven valid. Every action is sealed with a cryptographic timestamp, forming a chain of custody that is ready for auditors and exportable for regulators.

Frequently asked questions

Does ROOTKey replace my SIEM?

No - it complements it. Your SIEM detects events; ROOTKey answers which data can still be trusted after an alert. They answer different questions and work best together.

How does ROOTKey integrate with our SIEM?

Events are available through the REST API and webhooks for your SIEM.

Can a SIEM show what changed inside a file?

A SIEM works from the events that systems report, such as access and activity. ROOTKey compares the file itself with its sealed original and shows only what was altered - row, cell or field, before and after - with who, when and where.

Where does ROOTKey run?

ROOTKey runs as SaaS hosted in the EU, in your own cloud account, inside your own infrastructure, or as a hybrid that keeps the data on-premise with separate SaaS dashboards.
