Proofpoint Introduces Industry's First Dynamic, Machine-Learning Based Email Reputation Service
Proofpoint Dynamic Reputation and netMLX Machine Learning Fabric Deliver Highest-accuracy, Highest-performance Reputation Analysis and Connection Management Capabilities
CUPERTINO, Calif., April 30 -- Proofpoint, Inc., the leader in large-enterprise messaging security solutions, today introduced the industry's first dynamic, machine-learning based email reputation solution, Proofpoint Dynamic Reputation(TM). Proofpoint Dynamic Reputation is the only email reputation service that uses a combination of local, predictive behavioral data and globally-observed reputation -- analyzed by powerful machine learning algorithms -- to block incoming connections from malicious IP addresses. The system provides Proofpoint customers with an accurate, first line of defense against spam, directory harvest attacks, denial of service attacks and other email-borne threats while delivering substantial bandwidth savings.
"Unlike reactive, static reputation services that are forced to make critical trade-offs between connection shed rates, detection accuracy and response time, Proofpoint Dynamic Reputation delivers the highest performance in all three areas at once," said Sandra Vaughan, senior vice president of products and marketing for Proofpoint. "Our solution can block more than 80% of inbound connections with a false positive rate of less than one in one million. Global reputation profiles are updated every minute, ensuring the fastest response to new botnets and malicious IP addresses the moment that they emerge."
Machine Learning Creates Most Accurate, Up-to-date Source of Global IP Reputation
New functionality in Proofpoint Dynamic Reputation builds on Proofpoint's innovative connection management features, first introduced in version 3.0 of the Proofpoint messaging security platform. All Proofpoint appliances and software deployments provide built-in, predictive, behavioral analysis of local IP traffic that responds in real-time to eliminate email traffic spikes and block or throttle malicious connections from botnets.
Now, customers with high email volumes can add enhanced protection to their Proofpoint deployments to further reduce connection volumes at the network edge. This protection is provided by Proofpoint netMLX(TM) reputation analysis technology, a global machine learning fabric built over and extending the machine learning technology that powers each Proofpoint customer deployment.
Proofpoint netMLX creates the industry's most accurate and up-to-date database of reputation for IP addresses sending email across the Internet, allowing each customer site to benefit from the network effect provided by Proofpoint's real-time, machine learning analysis of global sender behavior. Proofpoint netMLX consolidates global data on malicious and valid IP addresses-processing both measured data from local MLX analysis at customer sites and observed data from external sources -- and produces a score that represents the sender's reputation, whether positive or negative.
Each minute, hundreds of data points for all IP addresses are parsed with advanced machine learning algorithms to generate extremely timely, accurate network reputation scores. Proofpoint Dynamic Reputation then uses these scores, combined with local behavioral data, to make intelligent decisions about accepting, throttling or rejecting incoming email connections.
Advanced Reputation Service Provides Optimal Balance of Performance, Accuracy and Response Time
Proofpoint Dynamic Reputation provides customers with a reputation service that uniquely balances the three critical attributes of a reputation service:
o Rapid response times: The one minute refresh rate provided by
Proofpoint netMLX global machine learning analysis, combined with local
behavioral analysis, ensures near real-time response. Proofpoint
Dynamic Reputation reacts to new spam sources, such as botnets, up to
an order of magnitude faster than competing, static reputation
solutions.
o Highest anti-spam and connection management accuracy: Proofpoint
netMLX processing of hundreds of reputation-related attributes at the
global level ensures that Proofpoint Dynamic Reputation always has
access to the most comprehensive, accurate assessment of IP address
reputation.
o Performance and efficiency gains: Connection-level block rates of more
than 80% help customers radically reduce email volume and handle ever-
increasing spam volumes without having to deploy additional hardware.
"Like many organizations, the City of Topeka, Kansas has seen inbound email volumes more than double in the past 12 months," said Bill Stephens, manager of electronic communications for the City of Topeka. "As this growth continues, Proofpoint Dynamic Reputation will ensure that we can keep pace with even massive spikes in email volume without having to deploy new hardware infrastructure."
