SonicWALL Email Security 300
Strengths: Extremely easy to deploy, configure and manage. Very attractive price
Weaknesses: Limited to email protocols. Missing other malware protection
Verdict: As an add-on for gateway protection to complement malware gateway solutions, this is a great buy
The SonicWall Email Security 300 v.7.0 solution is a purpose-built appliance providing gateway email content filtering and protection from viruses, spyware, trojan horses, worms and other types of malicious content in email. It can also prevent your organisation from sending out viruses in outbound email.
We were impressed with the compliance management capabilities of the product and also the reporting capabilities in the dashboard. Several templates and databases are included, as well as tools for building custom policies and databases.
The product we reviewed came with licences for both the McAfee and Kaspersky anti-virus engines.
The appliance came with SonicWALL's Time Zero Virus technology, which uses heuristic statistical methodology and virus outbreak responsive techniques to determine the probability that a message contains a virus. This option complements the virus-detection engines and provides the greatest protection for zero-hour threats.
A nice feature we discovered was the product's ability to prevent DHA (Directory Harvest Attack) and DoS (Denial of Service) attacks. There is email alerting for emergency alerts and user level access to review, manage and delete items in the junk mail folder.
SonicWALL also provides zombie detection, which protects networks against unauthorised software running on computers within an organisation, attempting to send out junk email, spam, phishing, virus or other unauthorised content.
With today's compliance and e-discovery requirements in mind, we found the product's ability to archive all incoming and outgoing email a major benefit. This can be accomplished by either forwarding to an external SMTP server or to a local file system.
The documentation was excellent, but we found that we really did not need it, as the web-based management was extremely easy to use. Numerous support options exist to cover the hardware, phone, email and web-based support and product and subscription updates.
The product lacked the malware integration we saw in the other products, but as a focused email malware solution, it does a great job for an attractive price.
