Progent has partnered with Postini to offer small businesses E-Mail Guard, a managed service that stops spam and email-borne viruses before they can penetrate your corporate firewall.

E-Mail Guard Blocks Spam and VirusesSpam now accounts for four out of five email messages. The spam epidemic seriously degrades the business value of your IT network by lowering productivity, slowing system performance, distracting IT management, and adding stress to the work environment. To solve this problem, Progent has partnered with Postini to offer small businesses E-Mail Guard, a managed service that stops spam and email-borne viruses before they can penetrate your corporate firewall.

E-Mail Guard handles the security and management of corporate email by providing continually updated spam and virus filtering, content filtering, and protection from email-based directory harvesting and denial of service (DoS) attacks. E-Mail Guard also includes monitoring, reporting and content management tools plus outbound filtering to help you troubleshoot your email system and define and enforce corporate email policy.

E-Mail Guard is based on Postiniís Perimeter Manager, a pass-through service which routes all your email to secure, fault-tolerant data centers ó the same ones used by Google, eBay and Yahoo ó where messages and attachments are screened using heuristic rules analysis. Clean email is forwarded to your email server, and suspicious email is tagged and delivered or quarantined to a web-accessible storage area for you to review. E-Mail Guard can be set up quickly and works with any email system by redirecting your mail exchange (MX) record.

The Postini Data Center

The E-Mail Guard service suite includes:

  • Spam Filtering using heuristic-rules that analyze senderís IP address and message content
  • Real-Time Virus Protection with customizable filters and quarantine areas for safe review
  • Attachment Filtering for policy-based blocking, re-routing or trusted partner pass-through
  • Connection Manager to block invalid SMTP connection attempts and Directory Harvest Attacks
  • Delivery Manager for load balancing and for storing messages in case your email server fails
  • Event-Based Alerts to notify your administrator instantly during attacks and system outages
  • Real-Time Monitoring and Graphic Reports for web-based views of system status and usage
Advantages of E-Mail Guard
Filtering email at the desktop, server or gateway wastes network bandwidth, disk storage and IT management time. E-Mail Guard uses Postini's Perimeter Manager to stand between the Internet and your corporate network, preserving both your system and personnel resources. Because Postiniís full-time security experts continually update filtering policies and virus databases, your email system always has the most current security technology without the intervention of your IT staff.

Perimeter Manager can also improve your email reliability. Postini's data center uptime averages 99.999 percent, far higher than small business email servers can expect to achieve. If your email server fails, messages are temporarily stored in a secure database at a Postini data center for delivery once youíre back on line. Perimeter Managerís load balancing technology restores recovered email by sending it at a measured pace in order to prevent your email server from being overwhelmed.

Perimeter Manager is also a powerful defense against Directory Harvest Attacks (DHAs). This is an aggressive technique used by spammers to gather employee email addresses by running scripts against email servers. DHA propagation is the primary driver behind the dramatic growth in spam targeted to corporate email users.

Benefits of E-Mail Guard

  • Accurately filters email to eliminate spam and viruses
  • Secures your email system from Directory Harvesting Attacks and Denial of Service Attacks
  • The Managed Service strategy keeps spam and viruses outside your firewall, increasing network performance and reducing stress in the work environment
  • Compatible with any email system ó no hardware or software to purchase, install, manage or upgrade
  • Automatic updating of managed services frees up your IT management staff
Key Features of E-Mail Guard
  • Secure external buffer stops unwanted or malicious email before it reaches your corporate firewall
  • Monitoring, management tools and graphic reports give you detailed visibility of all your corporate email traffic
  • Email policy, content and attachment management, plus outbound email filtering help you define and enforce your companyís email policies
  • Easily customizable by end users
  • Fail-safe architecture ensures no message is lost if your email server fails
  • Continual development, implementation and review of security policies and standards by Postiniís full-time staff of information security experts
  • Information security policies and programs are built around the ISO 17799 specification, the standard for enterprise computing
  • Good email is delivered instantly because filtering is done in memory, not on disk

Progent can also help you plan and implement a phased rollout of Postiniís services, select spam filters specific to department needs to reduce the risk of false positives, develop auditing and reporting practices, train your management, educate your end users on how to avoid spam and prevent virus propagation, and define an enforceable corporate email policy aligned with your business goals.

Why Does Progent Recommend Postini?
Gartner Research has recognized Postini as the number one spam filtering Managed Service Provider (MSP) with respect to the ability to execute. Postiniís administrative tools were recently cited by PC Magazine as the most advanced of any of the corporate anti-spam solutions they have reviewed, and in Network World's test of 16 anti-spam products Perimeter Manager scored the highest in accuracy for catching spam and delivered the lowest false-positive rate.

Postini processes over 1 billion messages weekly for over 2,700 customers and serves over 5 million end-users. The high volume of email processed makes Postiniís heuristic filtering engine continually more refined and efficient, and the companyís large customer base gives the Postini staying power that protects your investment in managed services.

Preserving Email Privacy
E-Mail Guard does not require users to provide personal contact or demographic information. Customers can deactivate services at any time by turning application settings off. Progent and Postini never sell or make available individual names, lists of users, or aggregate data to any third parties for gain. User configuration information provided to Postini is used explicitly to deliver services that match the clientís requirements and not for any other purpose. All user-specific information and email message information, including content, addresses, categorizations and IP addresses, are kept strictly confidential.

Impact on Email performance
Unlike store-and-forward solutions that use standard email server technology, Postiniís patented email processing method allows messages to be processed in real-time as the packets flow through the Postini servers. This also ensures that Postini does not expose customer data to hackers or potential loss of data. Postiniís filters process all email with no direct human contact with mail flow or individual messages. Mail messages are processed within milliseconds and immediately passed through to your email server. This eliminates any perceptible latency.
