What’s the cost of legitimate email being caught in your quarantine?

Can you block employees from infecting co-workers and customers with phishing threats?

Whether it’s the quarantined message you didn’t see that cost you a deal, thousands in clean up costs when employees click on phishing messages, or the time wasted removing spam from your inbox every day, the accuracy of your email filter counts!

Powered by patented machine learning technology, Sentinel Messaging spam and phishing technology efficiently filters millions of possible attributes in every email.

60 minutes every day per employee is lost dealing with missed spam and incorrectly blocked messages.

Advanced level scanning protection accurately filters emails by examining envelope headers and structure, content, email sender reputation, images and more, to prevent spam emails, malware, other malicious email and attachment-based spam reaching inboxes.

Proactively identify threats and minimize clean-up by catching malicious URLs before users click and get infected.

URL Defense enables protection on any device, at any time, from any location, by following the email and checking for the URL destination’s safety in real-time. A frequent technique used by hackers is to drive recipients to click on a link directing them to a website which is initially harmless but turns malicious after a period of time.
