The best IT stories are the ones that never became emergencies. Here's a look at the quiet saves – problems spotted and fixed before anyone noticed – alongside a client relationship that's lasted more than a decade.
Each of these started as a quiet alert on our monitoring. None of them became an outage. The examples are anonymised, but the pattern is exactly how proactive support is meant to work.
A monitoring alert flagged a server quietly running low on disk space – the kind of thing that silently breaks the nightly backup. Tanglin cleared the space and restored headroom before that night's backup ran. The client's data stayed protected, and they never knew there'd been a risk.
Caught: low disk space · Prevented: a failed backup
SentinelOne detected suspicious behaviour on a single workstation and automatically isolated it from the network in real time. The activity was contained to one device instead of spreading, and the machine was cleaned and returned to service – with the rest of the business none the wiser.
Caught: malicious behaviour · Prevented: a network-wide incident
Hardware monitoring picked up the early warning signs of a failing disk well before it gave out. The drive was replaced as planned maintenance, during quiet hours, instead of failing mid-week and taking a server down with it. A potential emergency became a routine swap.
Caught: early disk failure · Prevented: unplanned downtime
Because Tanglin's monitoring isn't tied to one office, a performance issue on a server supporting a distributed team was spotted and resolved remotely – before the people relying on it started their day. Distance is no obstacle when the watching happens centrally.
Caught: server performance · Prevented: a lost morning's work
A critical security update was rolled out automatically across the fleet as part of routine patching, closing a known vulnerability before it could be targeted. No staff action, no downtime, no window left open for attackers – just maintenance, handled quietly.
Caught: an open vulnerability · Prevented: a security breach
When a departing staff member's Microsoft 365 data was needed weeks after they'd left, it was still there – restored from Tanglin's backup to the exact point required. Microsoft doesn't keep that data for you; because Tanglin does, what could have been a permanent loss was a quick recovery.
Caught: data loss risk · Prevented: gone-for-good records
