MailCrusader – The Holy Grail of a Clean Inbox

Connecting to the Internet immediately puts your IT facilities at risk. Firewalls and other access control
devices can prevent hackers from entering your network, but cannot stop data which is “invited” onto
your systems. Email is an essential tool for communicating with customers and suppliers, but in a climate where viruses are commonplace, pornographic and other spam accounts for the majority of
email communications and scammers use so called “phishing” attacks to try to get hold of your bank
details and other identity theft, how can you protect yourself and your employees?

MailCrusader from Level 5 Internet Ltd is specifically designed to combat these threats. By checking
and filtering your email before it even arrives on your network, you have the peace of mind which
comes from knowing your systems are safe from email attacks.

Spam Filtering

A multi-layered defence keeps the spam away from your inbox.

1: Checks against known spam sources.
2: Checks databases of known spam emails.
3: Rule matching for words, phrases and other content commonly appearing in spam.
4: Bayesian database constantly learns about spam.
5: Regular updates ensure new spam methods are rendered ineffective.

Despite what some companies will tell you, it is impossible to detect and remove 100% of spam. Our
system has been tested on literally thousands of spam emails and we can guarantee that over 97% of
all spam will be detected.

Anti Virus Protection

You probably have anti-virus software on your desktop, but is this enough? No single scanner detects
100% of viruses. To ensure that all known viruses are kept away from your mailbox, MailCrusader uses
not one but two distinct virus scanning engines on each and every piece of email.

Anti-Phishing and other Dangerous Content

As a final protection, MailCrusader will stop any potentially dangerous content from reaching you. Certain types of files will often contain malicious code, so these are blocked and quarantined. Misleading hyperlinks are noted within the email, so users can make an informed choice before clicking.

Limitless Options

MailCrusader is a highly flexible service. Spam can be marked in the subject line, then delivered. It can
be deleted before getting to you. It can be forwarded to a separate email address. Email can be
scanned from any source. Quarantine measures can be relaxed. Our engineers will ensure that your
MailCrusader solution is tuned to comply with your company requirements and IT policy.

Pricing

A MailCrusader solution will cost no more than £1.50+VAT per user per month, with significant discounts on multiple users. Call us for a quote.
