Studies show 90% of the 200 billion emails sent out and received each day are spam messages. These spam messages are often harmless, but some may include malicious software (commonly known as malware) that compromise your security. You need reliable email filtering or anti spam services to protect your business.
There are two types of malware that are serious threats to businesses: spyware and Trojan horses. Spyware collects information about your network's users without your knowledge, while Trojan horses conceal other malicious programs that can do everything from keystroke logging to stealing passwords and credit card information. These malware aren't just threats to you, but to your business associates, customers, and anyone else you send emails to. This is why you need to find an email filtering service that has both inbound and outbound filtering.
When talking about spam protection for email, inbound filtering is what usually comes to mind. This type of filtering scans all emails you receive for threats, and alerts you about them or automatically put the infected emails into a designated spam folder. Inbound filtering is usually included in most email hosting services, such as Gmail and Yahoo Mail. Certain anti spam services may keep records of the email or IP addresses sending you spam messages, which makes it easier for you to block them.
Instead of scanning messages you receive through your email, an outbound email filtering service scans the messages sent from within your email system. Some hackers are able to gain access to your computer network without being detected, and could be using your own servers to send out malicious emails. Outbound filtering prevents this from happening by monitoring any potential threats in the messages you send, and detecting any suspicious activity such as sending out massive amounts of emails. This allows you to determine exactly where the spam or security threats come from, and enables you or your IT team to come up with an immediate solution.
Finding a Good Email Filtering Service
The tricky thing about security software is striking a balance between eliminating threats and making sure you still receive all your legitimate emails. Some filtering systems go over the top with their security measures, and may block messages from your business partners or customers. You want to stay protected but not risk losing any business relationships or opportunities because of your email's anti-spam protection.
There are many companies and software developers offering filtering services for businesses. When looking for reliable service providers, look for those who have years of experience and proven results under their belt. Doing a quick search on Google should reveal which among the available spam protection services are the most popular and effective, but you need to do more in-depth research than that. Find customer reviews and testimonials that talk about the software you are looking into, or ask your IT team for their recommendations.
Do not forget to keep your budget in mind as you search for filtering software. Some of the more effective packages are often pricey, but it is easy to find alternatives you can use until you manage to build up the funds for the best filtering services.
