Office 365 has many benefits, so it is no surprise that it is proving so popular with businesses, but one common complaint is the number of spam and malicious emails that sneak past Microsoft’s defenses. If you have a problem with spam and phishing emails, there is an easy solution to improve the Office 365 spam filter.

Office 365 Email Protection

More than 135 million commercial users are now on Office 365. Unfortunately, the popularity of Office 365 has made it a target for hackers. Microsoft has been proactively taking steps to improve the Office 365 spam filter to make it more effective at blocking spam and phishing attempts. Office 365 phishing protections have been improved and more malicious emails are now being blocked; however, even with the recent anti-phish enhancements, many businesses still have to deal with spam, phishing emails, and other malicious messages.

Businesses using Office 365 as a hosted email solution are likely to have their email filtered using Exchange Online protection or EOP. EOP does provide a decent level of protection and blocks spam, phishing emails, and malware. Osterman Research confirmed that EOP eliminates 100% of known malware and blocks 99% of spam email but struggles with the last 1%. Many businesses have found that EOP blocks basic phishing attacks but comes up short at blocking more advanced email threats such as spear phishing and advanced persistent threats.

To improve the Office 365 spam filter, it is necessary to upgrade to Advanced Threat Protection, the second level of protection offered with Office 365. The level of protection is much better, although Advanced Threat Protection cannot identify zero-day threats and falls short of many third-party solutions on blocking other advanced threats. A SE Labs study in the summer of 2017 found that even with the additional level of protection, which is only available in the Office 365 E5 license tier, protection only ranked in the low-middle of the market.

The number of cases of hackers exploiting vulnerabilities in Office 365 and the volume of direct attacks on Office 365 users has seen an increasing number of businesses looking for a way to improve the Office 365 spam filter further.

An Easy Way to Improve the Office 365 Spam Filter

Businesses that want to further improve the Office 365 spam filter (and those looking for an Office 365 Advanced Threat Protection alternative) need to consider implementing a third-party anti-spam solution.

Fortunately, there is a solution that will not only improve Office 365 spam filtering, it is quick and easy to implement, requires no software downloads, and no hardware purchases are necessary. In fact, it can be implemented, configured, and be up and running in a few minutes.

SpamTitan is a powerful cloud-based email security solution that has been developed to provide superior protection against spam, phishing, malware, zero-day attacks, and data loss via email.

In contrast to Office 365, SpamTitan uses predictive techniques such as Bayesian analysis, machine learning, and heuristics to block zero-day attacks, advanced persistent threats, new malware variants, and new spear phishing methods.

SpamTitan searches email headers, analyzes domains, and scans email content to identify phishing threats. Embedded hyperlinks, including shortened URLs, are scanned in real time and subjected to URL multiple reputation checks, while dual antivirus engines scan and block 100% of known malware.

SpamTitan also incorporates data loss prevention tools for emails and attachments, which are not available with EOP. Users can create tags for keywords and data elements such as Social Security numbers to protect against theft by insiders. SpamTitan also serves as a backup for your mail server to ensure business continuity.

With SpamTitan you get a greater level of protection against spam and malicious emails, a higher spam catch rate (over 99.9%), greater granularity, improved control over outbound email, and better business continuity protections.
