Why Cisco Secure Email

Why Is Email Security So Important?

The volume and sophistication of email-based threats continue to grow at an unchecked pace. Most organizations observe that as much as 90 percent of their incoming mail is invalid (spam, viruses, etc.), with the total number of incoming messages increasing every year, even as the number of employees stays constant. These email security threats are fueled by a powerful profit motive associated with spam, fraud, and information theft. This creates resources that bring professional engineers into the business of developing new threats, further exacerbating the situation. As this cycle does not appear to have a natural equilibrium, threats are expected to continue to grow in volume and sophistication for the foreseeable future.

There are no “silver bullets” to eliminate the flaws found in email. The ultimate answer will likely emerge as a mixture of many complementary solutions. The sustained viability of email demands a convergence of market-driven research and technological development.

What Is the Cisco SenderBase Network?

Cisco Secure Email harness the power of the SenderBase® Network. This powerful threat tracking database captures data from more than 100,000 organizations worldwide, providing a large and diverse sample of Internet traffic patterns.

  • SenderBase receives over 30 billion queries daily.
  • Using SenderBase data increases malware catch rates by more than 20 percent over signature-based scanning alone – an unprecedented increase in efficacy.
  • For live threat updates and real-time access to your SenderBase Reputation Score (SBRS), visit https://www.senderbase.org.

What Are Cisco Secure Email’s Security Technology Differentiators?

Cisco Secure Email AsyncOS® is a unique, high-performance software architecture designed to address concurrency-based communications bottlenecks and the limitations of file-based queuing.

Cisco Secure Email Reputation Filters perform a real-time email threat assessment and then identify suspicious email senders. Suspicious senders are rate limited or blocked, preventing malicious traffic from entering the network.

Cisco Secure Email Anti-Spam combines best-of-breed conventional techniques with Cisco Secure Email’s breakthrough context-sensitive detection technology to eliminate the broadest range of known and emerging email threats.

Cisco Secure Email Outbreak Filters detect new virus outbreaks in real-time, then quarantine suspicious messages – offering protection up to 42 hours before traditional antivirus solutions.

Cisco Data Loss Prevention technology provides comprehensive DLP policies and remediation options, unparalleled accuracy, and easy deployment and management capabilities – meeting acceptable use policy and compliance requirements readily.

Cisco Secure Email PXE encryption technology revolutionizes email encryption – meeting compliance requirements while delivering powerful business-class email features.
