How quickly and effectively can it analyze traffic for threats? The best rule of thumb is to make an educated guess about your bandwidth requirements in three years, double it, and then select a firewall that is very comfortable with securing that volume of traffic. But even though most businesses expect their technology to last two to four years, over half end up purchasing additional tools and workarounds every one to two years to either fill gaps in their existing solution or compensate for creeping performance issues according to research. Selecting a firewall should be a long-term investment. Effectively analyzing streaming traffic in real-time requires a much more specialized and intensive process that most firewalls cannot deliver. Just as advanced graphics demand specialized GPUs to render rich video streams, the increasingly sophisticated technologies and tactics used by today's cybercriminals demand more processing power. Generic CPUs were never developed to perform specialized inspection, analysis, correlation, and response tasks modern firewalls need to deliver-including things like performing deep inspection of encrypted traffic that can quickly overwhelm generic CPUs. What type of inspection do you require from your firewall? Decrypting SSL including the latest TLS1.3, is the key to identify bad actors hiding in those encrypted paths. Your firewall must be able to quickly identify applications, scale to process and secure increasing network traffic demands, especially now as most traffic is encrypted hitting 95% as estimated by Google’s latest transparency report. As the volume and maturity of users, devices, and applications increase, bandwidth demands naturally intensify. Yesterday's ultraperformance is today's baseline requirement. So, what questions do you need to consider when choosing a firewall for your business? Here are some critical considerations: Does the throughput match your business needs?Īs anyone can tell you, throughput demands are a moving target. The challenge is sifting through the vast array of firewall options to find the best one for your organization now and that can grow with you as your organization and network expand. How to Choose a Firewall That Can Grow With Your Organization The right firewall will help prepare your business for growth by consolidating the number of products you must manage, reducing costs and cycles, and making the overall management of your network infrastructure more effortless and cost-efficient. Regardless of your configuration, a firewall still serves as the critical inspection point for all network traffic. While it's impossible to foresee how growth and expansion will affect your network and security requirements, making a wise investment is still possible.
