We are looking to replace our current web-based spam filter. Our current vendor is doing an adequate job, but we are beginning to run into issues. Multiple senders are having their emails caught in &quot;limbo&quot;. The messages will appear in our Exchange 1 hour - 2 days after being sent. The vendor's response to this has not been acceptable...it is time to move on.<br />
<br />
We are looking for a web-based &quot;first-line of defense&quot;. The product will spam / anti-virus check all email before it hits our on-site spam / anti-virus filter.<br />
<br />
I am looking for any recommendations. I have never researched this type of product before...so I am not really certain of which questions to ask.<br />
<br />
Thank you for the help,<br />

Web Based Spam Filter

Anti-virus software was originally developed to detect and remove computer viruses. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect from malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious layered service providers (LSPs), dialers, fraud tools, adware and spyware. Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity theft (privacy), online banking attacks, social engineering techniques, Advanced Persistent Threat (APT), botnets and DDoS attacks.

Anti-Virus Apps

Spyware is software that aims to gather information about a person or organization without their knowledge and that may send such information to another entity without the consumer's consent, or that asserts control over a computer without the consumer's knowledge; it has also come to include programs that engage in various kinds of electronic fraud. Anti-spyware is software that removes or blocks that software; some common vendors include Malwarebytes, McAfee, Spybot-Search and Destroy, Ad-Aware and BitDefender.

Anti-Spyware

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.
