Blog | On email?s birthday, here?s a look at how to keep it safe

What some consider to be the first email ? the first electronic message sent between two computers ? was transmitted 47 years ago, on October 29, 1969.

The exchange, from a computer at UCLA to one at Stanford Research Institute, took place over the military communications network Arpanet, one of the world’s first computer networks and the earliest version of what we today call the Internet.

Credit for inventing email as we know it, however, usually goes to Ray Tomlinson, who established the first networked email system on Arpanet in 1971.

It was also Tomlinson who decided on the ?@? symbol to separate the recipient and the recipient?s computer or network, establishing the email address convention that is still used today.

While email use on Arpanet grew quickly after that, email didn?t take off on a wide scale until the 1990s, when large network service providers like America Online started connecting their proprietary email systems to the Internet. By the end of the 90s, email was established as an essential tool in most offices.

Worldwide email has grown exponentially since then, and continues to grow. According to a recent report from the Radicati Group, there are over 2.6 billion email users worldwide in 2016, and that number will top 3 billion by the end of 2020. That same report estimated that the number of business and consumer emails sent and received each day will total over 215 billion in 2016.

With convenience comes problems

Despite all the conveniences of instantaneous electronic communication (remember inter-office mail carts and having to send disks and documents via overnight delivery services?), email is obviously not without its problems.

For example, on May 3, 1978, less than ten years after its invention, a marketer from Digital Equipment Corporation sent out the very first spam email.

Very quickly, whether it was unsolicited marketing messages, scams trying to trick the gullible out of money (a Nigerian prince needs your help), or phishing attempts at identity theft, spam became a huge problem. Ten years ago, our mailboxes were choked with it.

And while estimates vary, some estimate that as much as 80% or more of the world?s email traffic is still made up of this sort of unsolicited junk mail. Today, however, modern sophisticated anti-spam filters are so good that we shouldn?t see much of it because 99% of it is blocked.

For businesses, the security of email is still a major concern. Malware (including computer viruses, ransomware, spyware, and other malicious programs) is becoming increasingly sophisticated, and email remains a primary delivery method. According to Verizon?s 2016 Data Breach Investigations Report it is the #1 attack vector for cybercrime.

Malware?s growth has been explosive, with ransomware alone expected to generate $1 billion or more for the criminals using it in 2016, thanks to developments like Ransomware-as-a-Service (RaaS) that make it easier for anyone to conduct cybercrime. In fact, ransomware downloaders are among the most prevalent malware seen by FortiGuard Labs with new variants every day.

So what are businesses to do?

The solution for businesses is a secure email system that not only keeps threats from getting in, but also keeps your critical data from getting out.

And with the speed that new malware threats are being created, you need a system who?s protection is constantly being updated with the latest threat intelligence and, as importantly, capable of detecting new malware when it targets you first.

If your secure email gateway service has been in place for more than two years, it probably wasn?t designed to deal with today?s threats like ransomware.

And if you have moved to a cost-saving cloud-based email security service you may not be getting the latest protections that come from dedicated security experts.

Today?s cyber criminals are pouring unprecedented resources into creating malicious threats designed to cripple your organization — sometimes even teaming up to do so. You need someone on your side.
