With an appliance-based solution, you have a single point of failure unless you double your investment. Cloud Anti-Spam solutions are usually provided through a large network of fail-over servers ensuring unbeatable service availability.
If Internet connectivity is lost or if there is a power failure, incoming email cannot be queued on an appliance. With a cloud Anti-Spam provider, email will be safely stored in the cloud until the customer’s infrastructure is up and running again, letting clients enjoy better protection against email loss.
If an email server is under attack, an Anti-Spam appliance can become overloaded and start creating delays in email delivery. If the attack is fierce, email delivery can stop altogether. With a cloud Anti-Spam solution, the vendor’s network will absorb the traffic peak. The attack will go unnoticed on the client side and email delivery won’t be affected.
Messages containing viruses, malware and other dangerous content are eliminated in the cloud, before they reach the client’s infrastructures. Only clean email is delivered to the client’s network.
When there is a cloud Anti-Spam vendor in the picture, best practice is to restrict acceptance of incoming email to messages coming from their network. That way, every message reaching the client’s network has first been scanned by an email security solution and spammers can no longer attack the client’s IP address directly. Ensuring that email communications are no longer accepted from the Internet at large provides another layer of security.
With an Anti-Spam appliance, there is an initial up-front hardware acquisition cost plus recurring licensing and update fees. Anti-Spam solutions are billed on a per user basis and usually pricing scales down according to the size of the organization. Plus, since cloud Anti-Spam solutions provide built-in redundancy, there is no need to pay for hot replacement.
Buying an Anti-Spam appliance is a capex expenditure that cannot be fully deducted in the period when it was incurred. But cloud Anti-Spam subscription fees are an operating expenses that allow clients a full deduction in the accounting period during which the cost was incurred. When you manage tight IT budgets, this can make all the difference.
An Anti-Spam appliance must be installed and configured. And it runs on the client’s server, using CPU, electrical power and physical space. With a cloud Anti-Spam solution, activation comes down to a simple modification of the MX records. There is no installation and initial configuration is usually very simple. Nothing at all runs on the client’s infrastructure.
A good quality cloud Anti-Spam solution should require very little management whereas Anti-Spam appliances must be updated regularly to maintain their efficiency level.
Spam and harmful messages delivery can represent up to 50% of your bandwidth usage. With cloud Anti-Spam solutions, only a flow of clean email is delivered to your server, completely eliminating bandwidth waste.
With current spam levels around 67%, cloud Anti-Spam solutions eliminate 4 connections out of 10 in the cloud. This reduces the email server’s load which in turns increases it’s efficiency and lifetime.
A good cloud Anti-Spam provider has all the email diagnosis tools on hand and should provide top-notch technical support which will help easily troubleshoot and resolve any email issue.
