With users working remotely and data now housed in multiple cloud applications, securing access to data is essential to a modern digital infrastructure. The rise of hybrid work has challenged the scalability of traditional VPNs, and hybrid multi-cloud architectures have made legacy centralized VPN concentrators impractical. Zero trust network access (ZTNA) is an emerging class of technology that addresses these new remote access requirements and challenges. Check out these slides to discover why it’s time to transition from legacy VPNs to ZTNA solutions. You will also learn more about: - Why legacy VPN technologies cannot address the needs of modern enterprises - How ZTNA helps secure remote access in the era of hybrid work and multi-cloud architectures - The best way to transition to a next-generation solution

85% of IT orgs:
Pandemic permanently expanded remote/hybrid work
19% Pre-pandemic 50% Post-pandemic
Remote workforce in the average enterprise
“After the pandemic, we expect about 70% of
people to go into the office only two or three days
a week. Another 15% will never go back.”

Multi-Cloud Networks

88% of companies will be multi-cloud by 2024
47% will have three or more providers
“There is no one tool that can identify all of our
[cloud-based] VPN clusters and draw a picture to
show us our weaker management controls and
where our weaker policies need to be adjusted.”

VPN challenges with multi-cloud
• Hub-and-spoke networks are history
• Concentrators in data centers add
latency
• VPN services from cloud providers
are bandwidth limited
Security risk is the #1 pain point in multi-cloud networks
Only 12% report no difficulty with consistently managing
network security policies across providers

Silo Conflicts in Detail:
68% of enterprises report zero trust
prompts closer collaboration
between NetOps and SecOps groups
“[Zero trust] is going to be highly collaborative, and I see us having issues
there. Security will come to us and say, ‘We want to do X.’ Okay, great.
What does that mean? We’re not sure. And who is going to pay for it?”
Budget 32%
Project complexity 31%
Skills gaps 31%
Conflicts between NetOps and SecOps 29%
