Security events (SIEM)

Security events that know which device they are about

Logs arrive at your own endpoint and are matched to the device, asset or site they name. Router events are tied to the exact interface and link.

01

Events with context

Each event is matched to the device, IT asset or site it names, so an alert starts with where, not just what.

02

Impact stated

Link alerts state what is at risk: circuits, wavelengths, LSPs, VRFs, services and customers.

03

Alerts go where you work

Slack, Teams, email, webhooks, PagerDuty, Opsgenie or ServiceNow, with the route shown on the alert.

How it works

From setup to answer in four steps

  1. Create a source

    Each source has its own key, which you can generate, rotate and revoke.

  2. Send logs

    POST NDJSON over HTTPS to your per-tenant endpoint.

  3. Write rules

    Threshold, pattern, absence and correlation rules are evaluated every minute.

  4. Work the alert

    Alerts move from open to acknowledged, investigating and resolved, or false positive, and can raise a ticket.

Four rule types

Threshold, pattern, absence (a silent source) and correlation: two rules within a window on the same site, device, interface or link.

Retention you set

Logs are searchable for 90 days by default, then archived for 365 days by default. Both periods are set per source. Screens include a log viewer with facets and a histogram, source health, volume metrics and a dashboard designer.

FAQ

Frequently asked questions

How do logs get in?

By HTTPS to your own ingest endpoint, with a key per source that you can rotate or revoke.

Which formats are understood?

JSON, syslog (RFC 5424 and 3164), CEF, and router syslog from Nokia, Juniper, Arista and Cisco IOS XR.

Does an alert know which kit it is about?

Events are matched to the device, interface and link, and link alerts list the services and customers at risk.

How long are logs kept?

90 days searchable and 365 days archived by default, set per source.

Where do alerts go?

Slack, Teams, email, webhooks, PagerDuty, Opsgenie or ServiceNow, and a ticket can be raised automatically.
