Tumbleweed - Eingehender Email Schutz

Protecting the inbound email stream from viruses, spam, dark traffic and other malicious messages is critical for network efficiency, user productivity and policy compliance.  With malicious traffic continuing to grow at exponential rates, Tumbleweed can help you build an email security infrastructure that seamlessly integrates with your existing Exchange, Notes and GroupWise messaging environment.

Anti-spam

Spam represents both an enormous administrative nightmare and a costly productivity drain for virtually every enterprise, and IT organizations are under intense pressure from everyone from the CEO on down to do something about it. But spam is a particularly hard problem to solve. Determined spammers are continually inventing new techniques to "outsmart" the latest defenses, making it difficult to define spam, let alone block it. An emerging best practice for combating spam is to employ a perimeter defense that applies a potent combination of anti-spam technologies to capture the maximum amount of spam with the minimum amount of false positives.

Tumbleweed's anti-spam arsenal, including MailGate Email Firewall and MailGate AntiSpam Appliance, provides highly effective spam blocking and management capabilities, while easing the management burden associated with fighting the daily deluge of junk mail. Our Message Protection Lab issues more than 500 new rules a day through the proactive Tumbleweed Dynamic Anti-spam Service, so you can always stay one step ahead of the spammers seeking to invade your email systems.

With Tumbleweed MailGate solutions, organizations can:

• Quickly deploy spam protection – set it up on 30 minutes or less.
• Stop up to 98% of spam with a false-positive rate of only 1 in 100,000– never lose a business message.
• Significantly reduce IT overhead and administrative costs with a single solution for battling spam.
• Automatically receive spam definition updates, even every hour if you choose.
• Improve employee productivity by preventing spam from reaching their inboxes.

Anti-virus

Devastating email-borne viruses can circle the globe in a matter of hours, causing irreparable damage and loss to an organization's communications infrastructure. If your enterprise is infected, you not only incur costly downtime, but your employees can unwittingly spread a deadly virus to customers, partners, and prospects. The costs in terms of lost productivity, lost data, and lost customer confidence can be astronomical.

MailGate Email Firewall and MailGate AntiSpam Appliance provide a high-performance, scalable virus scanning and repair service that protects your enterprise email traffic at the Internet gateway. By inspecting every incoming and outgoing email communication, these solutions can detect and disinfect potentially damaging messages and attachments before they enter or leave your network.

With MailGate Email Firewall and MailGate AntiSpam Appliance, organizations can:

• Detect and remove email-borne viruses, worms, Trojan horses and other malicious threats in all major file types, including mobile code and compressed file formats.
• Automatically receive virus definition and engine updates with no interruption in virus scanning, maximizing uptime and accelerating the deployment of cures.
• Establish scanning policies, implement configuration changes, receive alerts, and generate reports from a central administration console.

Defense against "Dark Traffic"

“Dark Traffic,” which currently represents up to two thirds of all inbound port 25 traffic, is comprised of a combination of spam, spam precursors like directory harvest attacks (DHA), email denial of service (DoS) attacks, malformed SMTP packets, invalid recipient addresses, and other requests and communications unrelated to the delivery of valid email messages. Most email hygiene solutions examine the content of these communications, which is expensive in terms of processor overhead, storage, bandwidth, and additional server licensing to handle the additional volume.

MailGate Edge is a secure email relay that takes a network-based approach to blocking dark traffic, freeing content-based solutions to process the remaining third of traffic. 

With MailGate Edge, organizations can:

• Instantly reduce inbound traffic and load by detecting and preventing DoS and DHA attacks.
• Control SMTP errors and create IP-based block and allow lists.
• Verify recipients before they enter your network.
• Significantly reduce costs by optimizing network performance and eliminating the need for costly email server upgrades.

Anti-phishing

Phishing attacks use spam techniques to distribute large volumes of forged or 'spoofed' emails designed to trick recipients into divulging personal financial data such as credit card numbers, account usernames and passwords, and social security numbers. These fraudulent phishing emails can look very official, often using email addresses, Web links, and branding that appear to be authentic. By hijacking the trusted brands of well-known banks, online retailers, ISPs, and credit card companies, phishers are able to convince up to 5% of recipients to respond to them.

Phishing emails, like spam, can be identified and filtered out of inbound email to stop employees from ever receiving them. MailGate Email Firewall provides an anti-spam and anti-fraud engine that automatically captures phishing email before it enters your network.

With MailGate Email Firewall, organizations can:

• Protect employees from exposure to fraudulent email by stopping inbound phishing attacks.
• Receive automatic heuristic updates via Tumbleweed’s Dynamic Anti-spam Service to combat new phishing scams and techniques.
• Employ a Digital Signature defense by digitally signing outbound email at the Internet gateway, assuring recipients that the email they receive from your organization is authentic.
• Tumbleweed is the founding member of the Anti-Phishing Working Group (APWG), an industry association focused on eliminating the identity theft and fraud that result from the growing problem of phishing and email spoofing.
