Tredion uses Barracuda Managed XDR to help Dutch schools group contain cyber threats
Tredion ICT & Telecom, a Dutch managed services provider (MSP), has partnered with Barracuda for fifteen years to deliver robust cybersecurity solutions. Among Tredion’s customers is CVO Rotterdam e.o., a secondary school district serving more than 21,000 students and 2,600 employees.
As a longtime user of Barracuda Email Protection and Cloud-to-Cloud Backup, CVO ICT Manager Pieter Klijs had already come to trust our cybersecurity solutions.
Tredion was among the first of Barracuda’s Premier Partners to incorporate Barracuda Managed XDR into its service offerings, and has onboarded scores of customers to the service. That was one reason CVO chose them to replace their previous detection and response partner when that service wasn’t measuring up to their needs and expectations.
“We were looking for more integration and correlation [with other solutions], because we could only see what was logging in from our firewalls. We weren’t able to see where the user was coming from, and what kind of device. Then Barracuda told us, ‘It’s very easy for us to migrate over from this other partner to a managed XDR environment.’ So, we went looking for the right partner.”

Account takeover gets shut down
Barracuda Managed XDR and Tredion have both proven themselves. One of CVO’s challenges was managing and responding to alerts. With Tredion providing oversight and management, that challenge disappeared overnight.
“CVO Rotterdam e.o. doesn’t have enough resources to do the follow-up [on detection alerts] all by themselves, so that’s where we come in. For each high-risk alert, we do the follow up — such as blocking an account or making a new firewall rule. If needed, we call CVO Rotterdam e.o.. If it’s not urgent, they will look at it the next working day.”
— Roy de Bruijn, Commercial Director, Tredion
In the first six months of operation, Barracuda Managed XDR produced 2,789 alerts, including 26 rated “high risk.” Pieter says this is more than they received in the whole time they were with their previous partner.
And it was only in operation for four days before it caught a potentially catastrophic account takeover in one of CVO’s cloud accounts.
“On April 4 we had a true positive on the cloud monitoring part of the solution, which showed us we had a successful account takeover (ATO). The Barracuda XDR team called us because they saw the ATO, we did the checks, and within an hour the hacker was thrown out. I don’t think we would have been able to do this if we weren’t using Barracuda Managed XDR. It was great news for us.”
— Pieter Klijs, ICT Manager, CVO Rotterdam e.o.
Teamwork and continuous improvement
Between them, Tredion and Barracuda are helping CVO Rotterdam e.o. harden their security, improve response time and effectiveness, simplify regulatory compliance, and implement ongoing improvements based on the visibility they get into CVO’s systems.
