I tried to list offered services of all three companies and find out whether there are some significant differences, but based on their webpages all companies provide almost the same services.
As I come from the Czech Republic, our jurisdiction is based on civil law system which is greatly different from common law system followed by the USA. Based on the article Common Law vs. Civil Law4, I list features of both these systems.
Features of a common law system (USA) include
* There is not always a written constitution or codified laws; * Judicial decisions are binding decisions of the highest court can generally only be overturned by that same court or through legislation; * Extensive freedom of contract few provisions are implied into the contract by law (although provisions seeking to protect private consumers may be implied); * Generally, everything is permitted that is not expressly prohibited by law. Features of a civil law system (Czech Republic) include
* There is generally a written constitution based on specific codes (e.g., civil code, codes covering corporate law, administrative law, tax law and constitutional law) enshrining basic rights and duties; administrative law is however usually less codified and administrative court judges tend to behave more like common law judges; * Only legislative enactments are considered binding for all. There is little scope for judge-made law in civil, criminal and commercial courts, although in practice judges tend to follow previous judicial decisions; constitutional and administrative courts can nullify laws and regulations and their decisions in such cases are binding for all. * Courts specific to the underlying codes there are therefore usually separate constitutional court, administrative court and civil court systems that opine on consistency of legislation and administrative acts with and interpret that specific code;
* Less freedom of contract many provisions are implied into the contract by law and parties cannot contract out of certain provisions. In Czech law system there is generally a written constitution based on specific codes and precedent principle is not established. Based on paper The Criminal Justice System in the Czech Republic5, Criminal law in the Czech Republic is for the most part codified in one act called Criminal Code which is being continuously updated. Current version (only in Czech) is accessible from this address: http://portal.gov.cz/app/zakony/zakonPar.jsp?page=0&idBiblio=68040&fulltext=&nr=40~2F2009&part=&name=&rpp=15#local-content.
To be a successful computer forensics investigator, I have to be familiar with more than one computing platform. However, no one can be expert in every aspect, its important to develop my own network of professionals. I would begin by looking for groups of professional investigators in my surrounding for example Computer Technology Investigators Network (CTIN) and Technology Crime Investigation Association (HTCIA). I would start attending theirs meetings and try to become a member. Then if you are a member of one of these user groups, you get more credibility and can start share your experience, offer your skills, and try to maintain contacts by other professionals through e-mail. I think the best way how to find whether they are legitimate, is to discuss their experience and get recommendation for them from another people.
