Question: What is the difference between Proxy Sentinel™ and Firewall Sentinel™?

Answer: Proxy Sentinel™ is a full Internet proxy server, complete with its own secure firewall integrated in the same unit. Firewall Sentinel™ is essentially the same, but without the proxy server. Since many small companies
or small businesses running smaller networks don't always require the full
features of a proxy server, by buying only Firewall Sentinel™ they are
effectively saving almost 30% on the cost, and are still getting the best
Internet firewall protection there is in the industry.


Question: Who developed Proxy Sentinel™ and what is their experience in the field of Internet security?

Answer: Proxy Sentinel™ and Firewall Sentinel™ were completely developed by the General Center for Internet Services Inc. and took almost a year to develop. GCIS is one of Canada's oldest and largest Internet security, Internet services provider (ISP) and web hosting company. GCIS is also a major player in the field of e-commerce and B2B secure application development.

Additionally, in business since 1996, GCIS is an Internet application developer and integrator. The Center is also one of Canada's largest Internet Research and Development Center, with over 153 Canadian patents, over 55 U.S. patents and had approximately 330 patents pending as of August 1st, 2003. GCIS's intellectual property portfolio is as unique as it is diverse and fully reflects its serious commitment in developing and deploying innovative new Internet security technology and global Web-based solutions to modern business needs. GCIS is a North-American leader in Internet technology and Internet security development and integration.


Question: Two months ago, our company was hit with a network intrusion attack that resulted in the theft and misappropriation of confidential and very sensitive corporate documents. How can we prevent such attacks from further occuring? How can we tell if such an attack was done by one of our main competitors?

Answer: Unfortunately, that is a question we get almost daily. Since July of 2003, GCIS has made available Proxy Sentinel™, an extremely secure, scalable and almost impenetrable Internet proxy server that was designed and specifically developed to prevent such unwanted network intrusions. Since the Internet is now so much a big part of our corporate and private lives, companies, businesses and all levels of government must constantly take pro-active measures in preventing such attacks. As of July of 2003, many studies and government reports indicate that network intrusions and attacks, Denial of Service (DoS) attacks and outright hacking on corporate and government networks are rising continually. It is our hope that the Internet security solutions available on this website and, more specifically Proxy Sentinel™ will largely help prevent such attacks from ever happening.

As to the second question, using Proxy Sentinel™, with a reasonable amount of accuracy, it is now possible to determine approximately where an attack could have come from and then take the appropriate measures. However, Proxy Sentinel™'s mandate is not to determine where an attack came from but to protect the network it was intended to protect in the first place. By not letting any intruders in your network, you won't have to ever worry who might have tried to get in!

Proxy Sentinel™ is the most secure and dependable Internet proxy server on the market today.

Question: On top of all the many advantages of using a good proxy server and the increased Internet security provided by it, are there additional reasons or advantages I would need to know before making my decision?

Two answers:

1) Proxy Sentinel™ significantly reduces latency. The definition of latency is the delay between when a client (a browser such as Internet Explorer or Netscape Navigator) makes a request and until the entire response is delivered back to the client. If clients on a Local Area Network (LAN) are using the services of a caching proxy server such as Proxy Sentinel™ on the LAN, the caching proxy server will always be able to respond faster to requests for information and the download of new web pages.

2) Proxy Sentinel™ effectively reduces traffic on any network, thus, in the end, it makes the network run much faster, while at the same time eliminating any chances of bottlenecks. Since copies of an HTML page or a graphic are stored locally on Proxy Sentinel™, any request for that item after the first one can be served using the proxy's storage of files on its local hard drive. Note: Internet browsers also have caches of files, albeit so much smaller in size and capacity. Proxy Sentinel™'s internal cache feature refers to an entirely separate matter and is viewed as an important feature, on top of all the others, namely its high Internet security features.


Question: What else can Proxy Sentinel™ do for our company besides all of what's been said here?

Answer: On top of its all-important Internet security features, Proxy Sentinel™ is a very high-performance Internet proxy caching server for web clients. It fully supports FTP, HTTP data objects and even Gopher. Unlike traditional caching software, Proxy Sentinel™ handles all requests in a single and non-blocking I/O-driven process (Input-Output).

Proxy Sentinel™ keeps meta data and especially often-used web pages cached in its RAM. Additionally, it caches all DNS lookups, supports non-blocking DNS lookups and will even implement negative caching of failed requests. Proxy Sentinel™ fully supports SSL, extensive access controls and full request logging. By using a very lightweight Internet cache protocol, Proxy Sentinel™'s caches can be arranged in a hierarchy or mesh for additional bandwidth savings.

Proxy Sentinel™ consists of a main proxy server program, a Domain Name System lookup program DNS server, some optional programs for rewriting requests and performing authentication and also features helpful management and client tools. When Proxy Sentinel™ starts up, it spawns a configurable number of DNS server processes, in which each can perform a single, Domain Name System (DNS) lookup. This reduces the amount of time the cache waits for DNS lookups.
