Gartner recently published a short research paper aimed at answering this very question. Not surprisingly, Gartner recommends standardizing on a single vendor firewall platform since “More than 95% of firewall breaches are caused by firewall misconfigurations, not firewall flaws.” This pretty much puts to bed the age-old notion that deploying firewalls from different vendors can provide better protection in case a vulnerability in one firewall is exploited.
As a vendor that develops solutions that help organizations effectively deal with the complexities of managing firewall and network security policy, we are obviously no strangers to firewall misconfiguration. Manually managing multiple firewalls and large firewall rulesets is a daunting task even in a single vendor environment, and is amplified in a multi-vendor environment.

Most organizations have firewalls from multiple vendors due to mergers and acquisitions, and since companies will forever merge and acquire, standardizing on a single vendor is a moving target rather than a single concentrated effort.
In light of this companies must make sure they have:
