Anyone who regularly spends time online can tell you that security is always an issue. People have been illegally accessing computer networks nearly as long as networks have existed, and the skills and technologies used to do so have continued to evolve along with the networks themselves.
Hackers who use the information they access for illegitimate/criminal gain (called "crackers" among the hacker community) are a very real threat to individuals and companies of any size: individuals can have their private data accessed, and along with the resulting feelings of helplessness and violation, can have credit card numbers stolen, their computer hijacked as part of a botnet to attack others, or have their identities stolen and used to commit further crimes.
The situation for companies is at least as bad, as a breach in network security affects many people - the owners, employees, shareholders and clients (and others). Loss of financial data, user account information (remember what happened to Winners a few years ago?), proprietary research results or information, and more are compounded by the costs in time, money and public opinion that can haunt a company for years afterwards.
However, despite any potential risks, organizations and individuals can't just disconnect themselves from the Web - not only does it offer a wide variety of tools and benefits, but chances are everyone they know (and most of their clients) are on there too. Everybody has a website now, and most companies rely on the Internet not only as a means of finding clients, but of selling them their products or services as well (i.e.: e-commerce).
One of the great things about the Web is its ability to send large amounts of information quickly and easily.
But this brings us neatly back to the issue of security: if we don't want to resort to techniques used by spies since the early days of the 20th century (dead-letter drops, armed couriers, etc.) how can we make sure we can send large files (and receive large files!) securely?
Using an online large file transfer service not only takes care of security issues, but they are easy to use as well: unlike systems like FTP, however, the security features do not impact the user experience – it's very easy to use a large file transfer service, as the features operate in the background and require no special training or knowledge to use.
Combined with robust security on the user end (firewalls, hard-to-guess passwords, etc.), such services can ensure secure file transfer for individuals, professionals and companies in any field.
