Roughly 85% of all email received during the first quarter of 2010 was spam mail, according to a recent Kaspersky labs report. Spam is a multi-billion dollar industry that costs businesses billions of dollars and causes great annoyance to millions of internet users. Fortunately, there are many ways that businesses and ordinary citizens can fight the spread of spam and minimize its intrusion on commercial and personal internet activity.
Business Spam Solutions
Businesses concerned about spam and other computer-related security issues can choose between a large number of software and hardware solutions. Leading the way for serious protection is Barracuda Networks, a business security firm that provides a large range of spam and virus firewalls that can handle anywhere from 10 to 100,000 users. Barracuda firewalls can be clustered to support nearly any size of business. Spam and virus definitions are updated hourly by Barracuda networks and automatically pushed out to customer firewalls.
Of course, hardware firewalls are not the cheapest security solution, particularly for small businesses. Software-only solutions tend to be cheaper and often have per-desktop licensing to match smaller budgets. Symantec Endpoint Protection Small Business Edition claims to block 99% of spam in addition to providing malware protection, disk-based recovery, antivirus and email encryption. Corporate purchasing starts at 5 licences and can be purchased in exact denominations up to 1000.
Finally, services like Google’s Postini can filter spam for businesses (usually ISP’s) before reaching the local services. Individual users can log directly into Postini using their regular email address and passwords to verify whether filtered mail should be sent through to the user’s inbox.
Consumer Spam Solutions
Quite often, consumer spam solutions are based on the same technology as the corporate solutions. For instance, Symantec’s Norton Internet Security is a personal product that offers much of the same security features (including antispam protection) as Protection Suite but at a more consumer-friendly price. Competing commercial products include Kaspersky Internet Security 2010 3-User and ZoneAlarm Security Suite.
However, it’s the free solutions that many will opt for since many are available for non-commercial use.
