Traditional and next-generation firewalls can’t deliver zero trust
Legacy firewalls are costly and complex to maintain
Deploying physical and virtualized stacks of firewall appliances on-premises at every branch and edge location is prohibitively expensive. Device sprawl makes policy management inconsistent and error prone.
Traditional firewall rules fail to protect hybrid workers
Employees are working from anywhere and everywhere—in home offices, shared workspaces, and beyond. Unfortunately, inconsistent firewall policies that don't follow users lead to increased risk when connecting over public networks.
Backhauling traffic leads to poor user experience
Backhauling or hairpinning users’ internet- and SaaS-bound traffic to a data center via VPN and other network-centric tools for inspection creates connectivity bottlenecks, introduces latency, and degrades performance.
Choosing the wrong firewall can result in breaches
Selecting and sizing firewalls is based on branch size or bandwidth needs, and in a passthrough architecture, inconsistent policies across locations and users can end up compromising your network.
Check your attack surface, find out what attackers see
Request an in-depth attack surface analysis to see what apps and services you have exposed to the internet, vulnerable to attacks.
