Blocking Outbound Spam with Cyren’s Email Security Engine

Customer loss, as well as operational cost overruns, brand and reputational damage through blacklists, and even potential lawsuits are a few of the possible consequences service providers face as a result of spam coming from inside their network. Since the problem differs from inbound spam, dealing with outbound spam effectively requires a completely different approach to ensure real protection for service providers.

How Outbound Spam Impacts Businesses

Outbound spam can disrupt service provider businesses in multiple ways:

  • Blocked IP ranges: Spam sent from subscriber PCs can potentially cause entire IP ranges to be blocked. This includes customers’ legitimate traffic, which will negatively impact customer satisfaction.
  • Increased cost: The effort needed to remove blocked IP ranges from blacklists and handle angry customers can be very manual. Increased support infrastructure, and risk of potential litigation all also increase cost.
  • Persistent zombies: Blocking outbound spam isn’t enough. Without identifying the source, you can’t fully treat the problem. This allows spammers to change tactics and continue exploiting your network.
  • Ineffective solutions: Employing standard inbound anti-spam filters to outbound traffic oftentimes results in high rates of false positives as well as frustrated users.
  • Legislation: Some governments propose legislation that requires service providers to proactively deal with compromised accounts.

A Unique Solution to Outbound Spam

Cyren’s Email Security Engine for Outbound Spam is specifically designed to protect you by:

  • Detecting spam rapidly and accurately: A small local engine can analyze local traffic, blocking spam outbreaks as they start with almost no false positives.
  • Blocking any type of attack or attacker: It’s important to block spam, malware or phishing in real-time. Additionally, zombie computers, AKA compromised accounts, spammer accounts, and webmail spam are all analyzed and blocked.
  • Identifying the source: This sends alerts to your abuse team, providing samples of unwanted traffic.

How Outbound Spam Protection Works

Cyren’s email security solutions utilize patented Recurrent Pattern Detection™ (RPD) technology. This technology can analyze billions of messages per day – identifying outbreaks the moment they occur. To provide accurate protection from lower volume local or regional outbound spam, a local instance of RPD is deployed with each Outbound Anti-Spam Engine. RPD then analyzes the traffic to provide spam and phishing classifications based on its unique global view of outbreaks. 

Outbound emails are scanned by the Anti-Spam Outbound engine for global and locally recurring patterns. This helps to identify spam, phishing, and email-borne malware while also tracking each sender’s traffic statistics, such as mails per time period. Once a sender crosses a threshold, a notification is then sent along with the sender address. Samples of the blocked emails are then provided for analysis during the remediation process.
