Secure Your B2B Applications

Provide zero trust site-to-site connectivity and reliable partner access to B2B apps

Zscaler B2B™ enables site-to-site connectivity, connects business partners to private applications, and applies advanced cyberthreat and data protection policies for significantly reduced business risk.

Architecture Matters

Transform your architecture from firewalls to zero trust

Enterprises worldwide have spent billions on firewalls, yet breaches are increasing. The problem is simple: traditional firewall-centric architectures are no longer effective against cyberthreats.

Built on the principle of least privilege, Zscaler’s proxy architecture enables full TLS/SSL inspection at scale, with connections brokered between users and applications based on identity, context, and business policies.

The Problem

Traditional B2B solutions increase business risk

Today, applications are moving away from enterprise-controlled networks and into the cloud. With B2B site-to-site connectivity primarily based on VPNs, business partners are allowed access to critical apps and systems without comprehensive threat protection. Network-based connectivity requires inbound DMZs and open ports, increasing the attack surface and exposing the enterprise to relentless DDoS attacks.

  • Open ports with inbound DMZ
  • Lateral threat movement
  • Complex and expensive 
  • Vulnerable to DDoS attacks

  • Open ports with inbound DMZ
  • Risky file/data/app connectivity
  • Exposed app/servers
  • Vulnerable to DDoS attacks

  • Open ports with inbound DMZ
  • Risky file/data/app connectivity
  • Exposed app/servers 
  • Vulnerable to DDoS attacks

  • Open ports with inbound DMZ
  • Exposed app/API servers

Solution Details

Site-to-site B2B connectivity

Site-to-site connectivity based on zero trust network access (ZTNA) enables secure access to private B2B apps by establishing connectivity between locations on a dynamic identity- and context-aware basis.

Eliminate complex site-to-site VPNs or hub-and-spoke networks with a direct-to-cloud architecture that improves application performance.


B2B partner portal access

Zero trust network access limits partner access to only authorized private applications, without putting them on the network, and delivers comprehensive visibility into all partner activity down to the user, device, and named app level. 

Browser-based access enables partners to seamlessly and securely access authorized applications from any location, on any device.


B2C mobile app access

Modern mobile apps can easily adopt the zero trust architecture. Users on mobile devices securely connect to applications without exposing their device or the application host to the internet, preventing compromise by unauthorized users.

Business-to-consumer (B2C) mobile access also assures an enriched digital experience for your apps and services, from the users’ perspective, from any location, on any device, over any network.
