Passguard has entered into a new partnership with Sleutelnet, a cooperative of 37 healthcare providers in the northern part of Zuid-Holland. The collaboration introduces a new, region-wide layer of cybersecurity focused on the structural detection of infostealer infections.
A new focus on infostealer detection
As part of the agreement, Sleutelnet will offer Passguard as a managed service to its member organisations. The platform delivers continuous monitoring for infostealer malware—malicious software designed to extract credentials, session tokens, and other sensitive data from compromised devices.
Such infections often remain undetected, silently exposing systems, user accounts, and entire networks to further breaches.
Sleutelnet is widely regarded as one of the Netherlands’ most advanced healthcare cooperatives, connecting more than 30 providers across Leiden and surrounding areas to collaborate on shared challenges and innovation.
A collective approach to cyber risk
Through the partnership:
- Sleutelnet provides Passguard services to its member organisations
- Passguard monitors and detects infostealer-related exposures in real time
- Sleutelnet analyses findings and shares actionable insights across its network
This coordinated approach ensures that organisations are not only protected individually but also benefit from shared visibility and collective response capabilities.
Addressing a growing, shared threat
Infostealer infections rarely exist in isolation. In highly interconnected sectors like healthcare—where systems, vendors, and users frequently overlap—a single compromised device can have far-reaching consequences.
Despite this, proactive monitoring for infostealers remains uncommon at the individual organisation level. This partnership addresses that gap directly.
By adopting a collective detection strategy:
- risks can be identified earlier
- patterns across organisations become visible
- and the overall resilience of the region improves
As the adage goes, a network is only as strong as its weakest link.
Strengthening regional security
With this partnership, Sleutelnet and Passguard take a concrete step toward improving cybersecurity across the Leiden healthcare region.
