What it solves
What matters, explained with clarity.
Preventing a vendor from becoming a risk requires control, not blind trust. When working with third parties, every external access point is a potential failure if not properly managed.
A sophisticated cyberattack is not necessary: poor vendor management alone can create real risks.
- Vendors with excessive permissions increase the impact of any error or incident.
- Shared accounts between external teams eliminate traceability.
- Access that is not revoked when a service ends leaves doors open.
- Lack of clear third-party policies creates disorder and vulnerabilities.
The essentials, clearly explained
A poorly managed vendor is not just external support — it is a direct extension of your systems. Without proper control, it becomes an operational and security risk.
Designed for companies working with IT providers, maintenance vendors, software providers, or external services. If you do not know what access they have or what they do, you are exposed.
How we work
Intervene in a discreet, practical, and effective. way
1
Understand the context
First, review how vendors are managed within the company: what access they have, which systems they can enter,
how they are authorized, and whether there is clear control over their activity. Without third-party visibility, there is no real control.
2
Identify critical vendor risks
The key questions: do vendors have more access than necessary, do they use shared accounts, is access revoked when the service ends,
is there oversight of what they do in critical systems? This is where weaknesses that turn a vendor into a risk are detected.
3
Turn findings into decisions
Direct action: limit vendor access to the minimum necessary, assign individual accounts, set clear security rules, and monitor their activity.
Correcting this allows you to work with third parties without compromising security or business control.
