Tech Blog Series: Firewall Protection for Small Firms

March 17, 2014

Today, firewall protection is a basic need for both business and home networks. Since most computers come with some type of firewall protection right out of the box, many people do not see the need to invest in additional protection. Although some networks can be adequately protected under basic firewall protection, most cannot. This includes any law firm, no matter the size. Use the information below to find out what kind of firewall your firm needs.

What is a firewall?

The simplest way to define a firewall is that it is a barrier that controls what comes into your computer from the outside and vice versa. In other words, a firewall?s primary job is to prevent access to a private network (your computer or office network). When you access the Internet, your computer takes in and sends out data in the form of ?packets?. These packets contain vital information about the data they contain such as where the data comes from and where the data is going (on your computer). The firewall examines the packets to determine their safety, and will then allow the safe packets while discarding the unsafe ones. A firewall is busiest and most needed when the user is using the Internet, but it is an application on your computer that should be constantly running.

How to choose the right firewall protection

Firewall protection can come in the form of a program on your computer (software), a physical piece of hardware, or a combination of both. With a variety of products available ranging from basic to extreme protection, it is likely that you can find a product that fits your needs at a price you are willing to pay. Some of the factors you may want to consider in choosing a product are the following:

  1. Size: Not every firewall product is equipped to protect a network of computers. Make sure that each product you are considering has the capability to protect the number of computers used at your firm. Remember to always check that your firewall can function properly if you add more computers to your network. The size capacity of a firewall product is indicated by its RAM storage capability. ?RAM? stands for Random Access Memory, and is directly relates to how many computers a firewall is designed to protect. The more the RAM, the more users the firewall can handle. For a firm with less than 50 employees, a firewall with about 10 megabytes of RAM (or even a little less) should meet your needs.
  1. Security Level: This is where technical terms come into play. The basic security certification that is considered appropriate for most small networks is called ?ICSA?. Any other security certifications are helpful, but you should consider ICSA a necessity.
  1. Support: Name brand does come into play when choosing a firewall product. In the case of a software crash or hardware problem, Customer support is available for most software?s that are purchased. Many brands provide installation services and on-site technical support. Therefore, research the brands to make sure their customer service is reliable before purchasing their product.
  1. Price: There is a reason why price is at the bottom of this list. Protection is of the utmost importance, especially when it comes to sensitive and confidential documents and client information. Therefore, the price should not be a main concern when evaluating firewall protection. Use the above factors to determine a price range, and try to get the best product available. It will be worth it in the long run.

What to do after you are protected?

Once your firewall protection is in place, you will have established the first line of defense against individuals attempting to access your network without permission. However, there are countless other ways to strengthen your network security. Further in our Tech Blog Series, we will provide you with these additional security measures, including password encryption, PII protection, and more.

Receiving a quote from Protexure Lawyers is made super easy by the quick response time of their team. The renewal process is different from what I have ever seen, they offer a mostly filled out application which made the process even easier for me!

It was a pleasure working with you, - you gave me the most competitive price, quick turn around and good follow-up.

- Howard S. Kavenow

My account representative was very helpful in assisting me to complete my application. He made me feel like my questions and my business were a priority to him.

- Kim Davis

When faced with a substantial increase from our existing malpractice carrier, we received the name Protexure Lawyers from a referral. On contact, they were not only very prompt in processing our application, but also responded to several coverage questions we had. So far, the service has been excellent.

- Law Office of Shriver, O'Neill & Thompson

Mr. Dixon contacted me many months ago and I told him I renew my policy in September and that it would be helpful to contact me in July or August of this year. He did that; he was very patient with me and assisted me with the application process. He was extremely prompt in replying to my inquiries. I had been with the same company for many years so I was reluctant to leave them. He made the transition quite simple. I am fortunate that he was the salesman who contacted me.

- Robert Lewin

Thanks. You guys got my business because (a) your price was great, and (b) you were responsive and on top of things (a number of insurers surprisingly were not).

- Scott Maxwell

I first came in contact with Ryan on a cold call. Usually I am dismissive of these types of calls, but Ryan was brief and to the point - no hard sell or over promising. In the end, I received a less expensive policy than others I researched. I guess not all cold calls are a bad thing.

- Steve Hunter

Ryan offered to compare my current insurance with what he and his company could offer. I took him up on this, and gave him my pertinent information. I did my own research, and discovered that his quote was lower and the carrier had an A rating. I contacted my existing agent to see if she could match the quote. I had been her customer for a number of years and thought that was fair. She was unable to match Ryan's offer.

- Steve Hunter

I discussed some minor differences in the policies with my account representative, and throughout the process, he was easy to reach and called me back promptly. I value this a great deal. In the end, it was clear to me that I would receive a less expensive policy than I currently have, with the same coverage and excellent customer service.
