See & Secure the Third Parties Your Web Apps Depend On
Your applications don’t run alone. They rely on hundreds of external scripts, SaaS platforms, APIs and cloud services. Trust Monitor makes those dependencies visible, measurable and controllable.
The biggest brands trust AppCheck
The problem most security teams cannot see
Modern web applications are built from third-party components.
Marketing tools, payment platforms, analytics, customer support, authentication, content delivery and APIs all run inside your live production environment.
Every one of those connections is a trust relationship.
If one of them is compromised, attackers do not need to breach your servers. They simply ride the trust you already gave away.
Most organisations cannot answer a simple question:
Which external services are running inside my applications right now?
What Trust Monitor does
Trust Monitor continuously maps and tracks the third-party services your live applications depend on.
It gives you:
- A live inventory of scripts, domains, APIs and SaaS platforms running in production
- Visibility into how those relationships change over time
- Alerts when new or unexpected dependencies appear
- Insight into where risk is being introduced through external services
This turns invisible dependencies into something you can actively manage.
Why this matters
Third-party compromise is one of the fastest growing attack paths.
A single injected script, breached SaaS account or abused API can lead to:
- Data exfiltration
- Payment fraud
- Account takeover
- Compliance violations
- Loss of customer trust
These attacks happen inside trusted relationships, which is why traditional perimeter and application scanning alone does not catch them.
Designed for production environments
Trust Monitor works against live production environments in a safe, non-intrusive way.
It observes what your applications load, connect to and execute, without disrupting services or requiring code changes.
You see what is really happening, not what was supposed to be deployed.
How it fits with AppCheck
Trust Monitor complements AppCheck’s DAST, API and infrastructure scanning.
Together, they allow you to answer four critical questions:
- What is vulnerable
- What is exposed
- What is trusted
- What is changing
This creates a complete view of your true attack surface.
Who it is for
Trust Monitor is built for organisations that run complex, SaaS-driven web environments and need to:
- Reduce third-party and supply chain risk
- Meet regulatory and compliance obligations
- Prevent client-side and browser-based attacks
- Understand how their applications really work in production
See your real attack surface
Trust Monitor shows you the external services and integrations that your applications rely on, so you can control the risk they introduce.
