Email Firewall and Intrusion Prevention - Protecting the Network Infrastructure

Enterprise email infrastructures are vulnerable to a variety of attacks which can compromise the backbone of an enterprise e-mail system and devastate a company’s ability to conduct business as usual.

IronMail protects enterprises from denial-of-service, directory harvest attacks, port scans other types of attack. These attacks are blocked by the hardened IronMail appliance and never have a chance to reach the network.

Key Benefits and Functionality

TrustedSource with Connection Control

TrustedSource, CipherTrust’s best-in-class, next generation reputation system, constantly monitors data from over 4000 installed IronMail appliances around the world. IronMail’s Connection Control functionality uses the sender reputation information from TrustedSource to reject mail from senders that have a history of sending spam or other malicious attacks.

Hardened Operating System

IronMail is a purpose-built appliance built on a optimized, hardened operating system (BSD variant) to ensure that no unnecessary services are available to attack. After thousands of deployments and multiple penetration tests, no IronMail unit has ever been compromised, providing assurance to enterprises that no hacker, no matter how clever, will be able to get past the IronMail appliance protecting their email gateway.

Email Firewall

By blocking buffer overflow, denial-of-service, directory harvest, protocol attacks, and port scans, the IronMail platform is proven to protect the critical mail infrastructure from attack.

Intrusion Prevention System

IronMail prevents intrusions by detecting and blocking malicious code, unauthorized connections and other known attacks. Protocol enforcement is used by IronMail to identify new potential threats and disarm them before they can do damage. IronMail’s constantly updated set of attack signatures ensures that known attacks are identified and repelled in real time.

Email Anomaly Detection

IronMail is unique in applying behavioral techniques to pinpoint and block direct attacks on the email infrastructure. By granularly tracking message traffic, including senders, message volume, attachments, and a variety of other statistics, IronMail can detect when incoming or outgoing traffic is out of the norm. This usually indicates some type of attack is underway. Once detected, IronMail automatically applies rules to block the offending traffic.
