Insurance marketplace Lloyd’s has ended the cyber probe that it initiated following detection of unusual activity on its network.

In an update, Lloyd’s stated: “Last week, unusual activity was detected on the Lloyd’s network. As a result, the proactive decision was made to take some systems offline and perform a cybersecurity investigation. This was led by a dedicated team and two specialist partners, Mandiant and NTT.

“The investigation has concluded that no evidence of any compromise was found, and as such Lloyd’s has been advised that its network services can now be restored. We continue to work with our partners to monitor the IT environment as we restore services to the market, which we currently anticipate to complete by Wednesday, October 12.”

Prior to the conclusion of the cyber investigation, Lloyd’s said it wouldn’t reconnect the systems until it had the confidence that they were fully secure.

Meanwhile no explanation or further details were provided as to what could have caused the unusual network activity.
