Web App & VPN Access Control
- Organizations depend on a mix of web applications, cloud services and VPNs to get work done. But with more apps and remote workers, access security becomes critical. Quantum Access Manager (QAM) centralizes and simplifies how employees, partners and contractors securely access your web apps and VPN connections, without adding friction.
What Is Web App & VPN Access Control?
- Web App & VPN Access Control is a security feature that manages who can access your company’s internal and cloud-based resources. Instead of relying on static passwords or scattered login systems, QAM uses centralized authentication, authorization and adaptive policies to verify identity, apply the right permissions and block unauthorized access. This ensures only trusted users, devices and locations can connect, whether they’re accessing a SaaS app or logging into a VPN for internal systems.
How It Works in QAM?
- Centralized Authentication
- QAM acts as a single control point for access to both web apps and VPNs. Users sign in once through QAM, which validates their identity using MFA, certificates or Single Sign-On (SSO).
- Adaptive Access Policies
- Policies consider user role, device posture, location and risk level. For example, a remote login attempt from an unknown country might trigger MFA or block access.
- Granular Permissions
- Administrators can define who gets access to which apps or VPN networks. For instance, finance staff can access ERP systems, but not engineering tools.
- Smoother Web App Security
- QAM integrates with cloud apps like Office 365, Salesforce or Slack to implement authentication standards like SAML or OAuth.
- VPN Access Control
- QAM integrates with major VPN solutions to ensure only trusted devices and verified users can tunnel into your internal network
- For example, a remote developer tries to log into the company VPN from a new laptop. QAM first checks device compliance (up-to-date OS and security patches) and requires MFA approval. Only after passing these checks does the VPN connection open to make sure no insecure device gets in.

FAQs
Does QAM replace my VPN solution?
No. QAM works with your existing VPN infrastructure to add identity-based access controls and stronger authentication.
Can QAM secure both cloud apps and on-prem apps?
Yes. QAM integrates with SaaS apps, custom web apps and internal resources behind your VPN.
Is MFA required for every login?
Admins can configure adaptive MFA policies so users only get challenged in risky situations.
What authentication methods are supported?
QAM supports MFA, certificates, SSO (SAML/OAuth) and passwordless authentication for both apps and VPNs.
How does this fit into a Zero Trust strategy?
By verifying user, device and context for every connection, QAM enforces Zero Trust principles across apps and VPN access.
