SEVEN SYMPTOMS THAT TELL YOU YOUR LEGACY FIREWALL ISN ’ T FIT FOR ZERO TRUST

z

Zero Trust adoption is on the rise ...
Today ’ s IT security stakeholders are well aware that zero trust is the right security model for modern digital businesses . Surveys show that as many as 78 % of enterprise security programs have either adopted zero trust network access or are planning to do so in the future . They know that focusing directly on securing users , data , and applications – instead of the network – is key to protecting today ’ s data-driven , remote workenabled enterprises .
Decades ago , when hub-and-spoke network designs were state-of-the-art , firewalls and the networking infrastructures built around them were young , spry , and healthy . They were the right technology choice for that era , serving faithfully and doing their jobs well . In the modern cloud computing era , however , their presence is a burden , and castle-and-moat architecture designs are fundamentally incompatible with the zero trust paradigm .
Here ’ s a diagnostic guide outlining seven symptoms that your firewall is unfit for today ’ s zero trust security world . Any one of these seven symptoms is a sign that your organization needs a cloud security cure .
SYMPTOM # 1
A lack of visibility when trying to inspect traffic at scale
Regardless of their form factor , appliance-based firewalls are simply unable to inspect SSL-encrypted sockets layer ( SSL ) encrypted traffic at scale . This becomes more and more of a problem as the percentage of global internet traffic that ’ s SSLencrypted increases . Attackers know about this increase and are concealing more and more advanced threats within encrypted traffic .
If your firewall suffers from this condition , you ’ ll notice a performance degradation of 50 % or more whenever you try to turn on SSL inspection . You ’ ll have to upgrade to a higher capacity firewall or add more appliances ( or virtual firewall instances ) just to maintain the performance that ’ s acceptable for your users .
WHAT ’ S THE CURE ?
• Move to a cloud-delivered service that can provide cloud native ¬ firewalling capabilities rather than trying to leverage and scale virtual machine ( VM )
