40% of the Fortune 500 are on the zero-trust platform. In addition to just reducing attack surface areas and hiding applications, the time savings matter as much as the security gains. Six to nine months are saved in the typical M&A acquisition. Only a day to grant an entire company access to applications from a merged entity compared to weeks or even months under the old model. Cost takeout is another benefit of zero-trust. Zscaler doesn't add cost, it replaces expensive legacy stacks.

TL;DR

  • The FortiBleed incident compromised 74,000 firewalls globally without a new vulnerability, exposing a fundamental design flaw in perimeter-based security models.
  • Zscaler claims 40% of the Fortune 500 have adopted its zero-trust platform and measured real-world results in production environments.
  • Zero-trust delivers operational efficiency gains, including six to nine months saved per M&A acquisition and same-day application access for merged entities.

Summary

This short promotional clip uses the FortiBleed incident — in which 74,000 internet-facing firewalls were compromised across 194 countries without a new vulnerability — as a launching point for Zscaler's zero-trust value proposition. The clip argues that perimeter-based security is structurally flawed: exposing firewalls and VPNs to the internet creates an inherent attack surface that patching alone cannot eliminate. Zscaler positions its platform as the alternative adopted by 40% of the Fortune 500, citing measurable operational benefits beyond security: six to nine months saved during M&A integrations, the ability to grant an entire acquired company application access in a single day, and cost reduction by replacing expensive legacy network stacks rather than adding to them. The clip functions as a teaser driving viewers to a full on-demand webinar.

FAQ

What is FortiBleed and why does it matter for firewall users?

FortiBleed refers to a mass compromise of 74,000 internet-facing firewalls across 194 countries that occurred without a new vulnerability being exploited. Even fully patched devices with strong passwords were affected, indicating the problem is architectural — firewalls exposed to the internet create an inherent attack path regardless of patch status.

How does Zscaler's zero-trust approach differ from traditional firewall security?

Rather than defending an exposed attack surface, Zscaler's platform removes it entirely by hiding applications from the internet. The clip claims this approach has been validated by 40% of the Fortune 500 and delivers both security and operational benefits, including faster M&A integration and lower total cost by replacing legacy network stacks.
