FIREWALLS

A network without a firewall is an invitation for trouble.

A firewall is a device that keeps people out of your network. The safety provided by a security firewall is essential in the modern business world. Without network security your entire business is in constant danger of a data breach.

Our expert team of technicians works with a variety of firewalls because this isn’t a one-size-fits-all solution for everyone. Each business has different needs and it’s important to purchase the right system and get it installed and configured to your exact specifications.

We install and monitor firewall systems for companies both large and small. If you are ready for an updated system or would like to optimize your current configuration, call Acumen at (314) 333-3330.

TYPES OF FIREWALLS

  • PACKET FILTERS

    The simplest form of security ensures that packets containing particular pieces of information are stopped before they get into your network. It’s simple, cheap, but relatively ineffective in a complex IT support environment where sophisticated methods of penetrating a network firewall exist.

    Virtually all security firewalls have packet filter built into them but it’s still important to configure it properly. It’s easy to exclude words that your employees might need to conduct their daily business.

  • APPLICATION LAYER NETWORK FIREWALLS

    Application layer network firewalls are very useful in preventing virus and worm attacks on your IT network. They are also a common component of modern firewall systems.

    The key is in the details. You have to configure the security firewall properly before it works properly. If configured poorly it can result in disaster.

  • PROXY SERVER NETWORK FIREWALLS

    A proxy server is an extremely useful security firewall.  If one network is breached, your other networks remain safe. In larger network environments they are highly recommended.

    A virus can devastate your entire network and prevent you from doing business. If it migrates from one network to the next eradication can be very difficult. Proxy server network firewalls are a good idea.

  • Network Address Translation (NAT)

    Network Address Translation is a service that hides your network’s outgoing packets. This network firewall tool helps hide your network from network reconnaissance by a malicious hacker who surveys your network to try and learn more about it.

    If a malicious hacker is out to attack your network specifically or just looking for opportunities it doesn’t hurt to have NAT as part of your security firewall.
