Expert Technology Management and Support


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.



    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 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.


    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.

  • WAN Optimization

    Use NG Firewalls for site-to-site linking to take advantage of advanced WAN optimization capabilities.

    With data compression and decompression, TCP flow optimization, protocol acceleration, and data de-duplication, it’s like getting a new wide-open link; free of charge.

  • Dynamic Traffic Priority

    Dynamically group disparate links such as MPLS, T1, DSL, cable, and 3G, and eliminate costly backup links with automatic failover.

    NG Firewall balances and shapes traffic among links according to policies based on applications, traffic loads, and link status. As an example; VoIP and SAP can be reserved for fast MPLS lines, while email is shunted to slower T1 links.

  • Cost Effective

    With affordable, all-inclusive pricing, the Barracuda NG Firewall replaces several solutions with one appliance to deliver impressive cost savings up front.

    Ease of use keeps training and administrative costs low, while traffic intelligence and WAN optimization extend the capacity of existing infrastructure and delivers long-term savings.
