Firewalls used to consist of simple mechanisms to control access inside and outside the company. Traditional firewall techniques, such as port blocking and NAT, still play an important role; however, by themselves they do not have the profound power to stop today's threats. The main job of a firewall is to protect the company's network from Internet threats and enforce the company's security policies. The security policy will dictate what applications, services, ports and IP addresses are allowed and not allowed through the firewall. Companies need firewalls that not only consist of advanced protection tools, but also have other advanced capabilities integrated for other uses, such as VPN, WAN optimization, failover and high availability, VLAN support, dynamic routing, logging and reporting and Other useful utilities.
Choosing a firewall can be a daunting task when you look at the large number of firewalls in the market. Are you going with a market-leading firewall from Cisco, Juniper, Palo Alto and Checkpoint paying £ 10,000 more for a brand name, or do you buy a cheaper firewall that is still catching up and you really haven't had enough coverage and criticism on the world of security In addition, when you consider that this product will be the main entry point to and from your company, you must ensure that you have chosen a solid firewall with a proven reputation.
An example to choose the correct firewall would be to choose the correct door for your property. For example, if you were to buy a door, which door would you invest in? Would you invest in a door made of solid material, which is sturdy and bulletproof from a world-class manufacturer with promising criticism and references, or would you choose a door from your local DIY store that looks suitable but is actually hollow? The center comes with weak hinges, built with cheap material and comes with a protected lock that is very easy to avoid. Then there are the door manufacturers that sit in the middle, like a door that has been promised to provide good security but that has not really been tested and there are no independent references for the door manufacturer, and when asked Door manufacturer and If you question your door marketing claiming that it meets certain safety standards, you will find that these tests were tested internally by the developers themselves and not by a known third-party reviewer.
Firewalls come with different techniques to stop many of the current threats and come in different platforms and configuration methods depending on the environment they support. That is why you need to spend time investigating each firewall, what you and your company require of a firewall and carefully choosing the appropriate firewall for your company based on a balance of several aspects, such as the reputation of the provider and the overall cost of the product.
