After-hours OT monitoring for teams that run the day shift

Most plants already have someone who reads alerts between 8 and 5. The risk sits in the rest of the week. Nights, weekends and holidays make up well over half of all hours, and that is when a new device appears on a control network, a remote session starts at an odd time, or a sensor quietly stops reporting.

Our nights and weekends service covers exactly those hours. We handle nights and weekends OT security monitoring on the platform you already own, and hand control back to your team when they come in. Your people do not have to carry a pager for alerts that turn out to be noise.

This option fits teams that cover business hours themselves and want a second set of eyes for everything else. Typical examples include a plant with an engineer and a security lead on days, an operator with small remote sites, or a facility team that reviews the OT console each morning.

If your team already looks at alerts during the day, we do not duplicate that work. We cover the hours you cannot.

• Manufacturing sites that run lights-out or reduced overnight shifts.
• Water and wastewater operators with unattended remote stations.
• Facilities with building and facility systems that run all night.
• Lean teams that want a morning handoff instead of a pile of overnight alerts.

Many teams start with nights and weekends because it is a smaller step. If your staffing changes, a site is added or you want continuous coverage during the day too, you can move to 24/7/365 without rebuilding anything. Access, runbooks and escalation paths are already in place.

Work on control networks tends to cluster in planned windows, which makes unplanned activity easier to spot when someone is paying attention. A vendor connection at 3 a.m., a configuration download on a holiday, or a burst of scans against a PLC subnet all stand out against a quiet plant. They are also the events most likely to sit unread until Monday.

Overnight ICS monitoring does not mean your team is judged on every alert. We validate first, escalate only what holds up, and give your contact a severity and a reason. If something can wait for the morning, we say so and it goes in the morning summary.

Your team keeps the daytime relationship with the platform. We keep the night watch, and both sides use the same runbooks, contact tree and escalation path agreed during onboarding.
