Passguard
Tesorion is the first Managed Security Service Provider (MSSP) in the Netherlands to partner with Passguard for infostealer monitoring. Organizations looking for a Dutch supplier of Passguard solutions can turn to Tesorion for both platform delivery and managed services, implementation, and consultancy.

Dutch Passguard partner
With Passguard, we are strengthening our services in the areas of credential security, dark web monitoring and protection against infostealer malware. This enables us to help organizations detect stolen login credentials and compromised accounts at an early stage and limit risks.
What does Passguard do?
Infostealer malware collects user names, passwords, session cookies, and other sensitive data from infected endpoints. This data is then distributed via underground marketplaces and forums.
The Passguard platform ptovides:
- Real-time monitoring of infostealer logs
- Detection of compromised business accounts
- Insight into exposed credentials and session tokens
- Dark web monitoring focused on infostealer data
- Risk indication per user or domain
This gives organizations early visibility into data breaches that occur outside the traditional perimeter.
Why infostealer monitoring is essential
Traditional security tools often do not detect that credentials have already been compromised.
With Passguard
- Stolen credentials are quickly identified
- Accounts can be reset or blocked immediately
- Lateral movement is prevented
- The risk of ransomware attacks is reduced
This aligns directly with our managed security approach, in which prevention, detection, and response are integrated.
