Network World - Email security appears grounded as attacks continue to take flight

“The (email security) market is moving from a static rule-based approach that relies on seeing the same virus or spam message across many customers, to dynamic machine-learning-based systems that learn and adapt to the attacks. Future email security systems will need to learn each customers’ environment and find anomalies in real-time,” said Asaf Cidon, vice president of content security services at Barracuda.
