Evios is a fully managed enterprise class anti-spam appliance
deployed at your Internet gateway that filters spam and blocks
viruses before they get into your network. Evios makes e-mail
communication more useful and secure. Time proven technology
combined with flexible configuration result in a 95+% spam
Why do you need a mail filtering
Email is the life-blood of many businesses today. Unfortunately,
SPAM, or unsolicited commercial email (UCE), threatens to
overwhelm corporate network infrastructure, network and server
administrators’ already-busy schedules, mail server
resources, and user inboxes. Legitimate messages are buried
under inboxes overflowing with unwanted messages, or simply
get lost in the shuffle due to overtaxed servers and infrastructure.
SPAM accounts for 50-90+% of all incoming email volume for
most of our customers.
Why do I need a managed Evios Mail
Most products or services that claim to filter out SPAM fall
short in one (or more) of several areas, including:
- They use only a very small number of techniques to detect
- Worse, they use some of these techniques as a definitive
classification of spam or not spam.
- They use techniques that require the product or service
to be “trained” by the mail users (most users
will not do this!)
- They operate after the message has already touched the
mail server – which limits the types of analysis that
can be performed, and wastes even more resources at the
To greatly improve accuracy, Evios uses a comparatively
large number of techniques to detect SPAM, which can be tweaked
(if desired) by site mail administrators, and even by end-users.
(The mail administrator(s) can permit or deny this, in fine
What are the advantages of the managed
Evios Mail Appliance?
Most businesses don’t have the staff or resources available
in-house to implement first-class SPAM filtering. Evios allows
you to affordably leverage our experienced personnel to achieve
more effective results than would probably otherwise be realized
using simpler techniques and products.
Among other things, Mail By Design maintains the hardware
and software, constantly updates the system to meet new threats,
and provides sparing. The configuration database of each Evios
Mail Appliance is backed up remotely - should a hardware failure
occur, a new box can be built to replace it very quickly.
Evios is very flexible – options can be set on a per-appliance,
per-domain or subdomain, and even per-user level as desired.
Can Evios do anything besides filter
Of course! Evios can, among other things:
- Remove all executable attachments – this is extremely
useful for defeating so-called Day 0 viruses and worms (Day
0 refers to a virus or worm that spreads before antivirus
packages can be updated to detect them)
- Perform detailed mail logging and reporting
- For a traveling user, replace large attachments with
a private URL – so the user isn’t forced to
wait for extended periods of time when checking a POP mailbox
- For messages from an unknown address at a competitor
company, quarantine messages until either an administrator
clears the message or the sender agrees to an Acceptable
Use Policy, at which time the message is released
- Eliminate “forged” messages (email with an
internal From address, but which arrives from the outside)
How is the Evios Mail Appliance
protected from hackers?
All network access to Evios is heavily filtered. In addition,
administrative access by Mail By Design is accomplished using
strong encryption and authentication.
How is Evios customized?
There is no configuration or customization of the Evios appliance
required of the end users or network administrators. The default
settings work extremely well in most cases. If changes are
desired, they can be made through the Evios web management
interface. There is a web interface for the mail administrator(s),
for domain/sub-domain administrators, and for end users. All
levels can be utilized, or disabled as needed.
How does Evios remove mail determined
to be SPAM?
Evios by default classifies every email message into one of
three categories: Not SPAM, Probable SPAM, or SPAM. If a message
qualifies as SPAM or Probable SPAM, Evios can:
- Pass the message through unaltered
- Add a header or subject tag to the message so the mail
server and/or client can treat it (for example, file it
into a “SPAM” folder for review)
- Delete the message outright
What kinds of reports does Evios
Evios logs everything that goes through the box except for
the body of the message. Reports can be generated for individual
users, particular messages or similar messages, number of
messages received, number of spam messages and percentages
of legitimate mail versus spam.
How is Evios backed up?
Configuration information is backed up via secure link to
Mail By Design.
Does Evios require a particular
type of mail server?
No, Evios works as a mail gateway completely separate from
the mail server.
Can I use Evios if I don’t
have my own mail server?
Yes. The only requirement is that you have your own email
domain or subdomain.
Can Evios act as my mail server?
No. Evios is an email gateway, not a server.
Do you offer any High Availability
Yes. Multiple appliances are able to operate in parallel for
redundancy and/or load balancing.
At about what mail volume is a second
Each Evios appliance can handle approximately 250,000 messages
per day. When demand exceeds that, a second Evios box can
be installed and operated in tandem.
How much does Evios cost?
Evios is available in several tiers, including:
- Evios Lite - for smaller customers (up to 100 mailboxes)
– a shared server is used for greater cost-effectiveness.
Configuration flexibility is still available as it is with
a dedicated appliance
- Evios Full - one or more dedicated appliances are placed
on your external network, dedicated to your email
- Evios Pro - For service provider or high availability
Pricing is based on service tier plus the number of users
– please call your account executive for information
Where does Evios sit in my Network?
Evios sits in front of the firewall outside your network.
As such, there are no complex router or firewall configuration
How long does it take to install
Evios can be installed within 15 minutes. Its simplistic architecture
makes installation and removal, if necessary, a brief and
uncomplicated process. There is no network outage or downtime
required for Evios installation.
