Top 10 Features: Clearswift SECURE Email Gateway Modern business simply couldn t function without email. However, both incoming and outgoing messages can pose significant risks to the security of company networks and confidentiality. It is therefore vital that an organisation s email gateway is able to mitigate spam, neutralise viruses and prevent data leaks without hindering the free flow of messages. The Clearswift SECURE Email Gateway is a trusted email gateway security solution that gets the balance right. With the Clearswift SECURE Email Gateway installed, your organisation can be confident that it is protected from digital threats and data leaks while employees communicate freely by email. Inbound Threat Protection With thousands of new viruses and targeted attacks being created daily, the SECURE Email Gateway provides a number of unique methods to keep your perimeter defences tight. From viruses to malware, in-and-outbound threat protection keeps your inbox free from malicious emails and spam. Offering zero-hour anti-malware protection, IP reputation based filtering and signature based anti-virus, together with deep file inspection to identify hidden malware, you can be confident that your email is safe. Spam Protection Spam continues to be an annoyance for everyone, wasting bandwidth, processing time and cluttering inboxes; the current estimate for daily spam volumes is 93 billion messages per day. The SECURE Email Gateway employs a number of different techniques to deliver 99+% spam detection with minimal administration. Our multi-layer detection conducts initial checks using TRUSTmanager based on realtime repulation filtering, using RBL lists, reputation data and anonymous feedback from our customers Gateways, allowing Clearswift to score 60m+ addresses every 15 minutes. If further checks are needed, SpamLogic employs a number of filtering approaches to sort different types of spam, including: Greylisting Backscatter prevention (NDR) RBL SPF Recipient authentication Signature based anti-spam Heuristics Bayesian learning engine. Content Inspection Email is second only to removable storage as the most common cause of data leakage and it s estimated that one in five outgoing emails contains data that poses a legal, financial or regulatory risk. Given email s centrality to business communications, organisations need high-quality scanning for their message traffic, checking for potential violations (accidental or otherwise) without hampering business-critical data flows. 2

Policy Controls With flexible policy controls, Clearswift s SECURE Email Gateway gives you complete, bi-directional control over your organisation s email. Policy routes and rule-sets can be as complex as the organisation s AUP requires them to be. Depending on the result of a particular content rule and the context within which it has been detected, flexible application of policies is allowed. Content rules check that the data being sent via any given email route is acceptable for delivery. Examples of content rules include detection for: content, file type, spam, viruses, inappropriate or registered Images, filename or message size amongst others. Encryption Clearswift offers a wide range of encryption options that enable you to automatically encrypt emails, securing any information passed internally and externally in your organisation. For users who simply require encryption on messages between themselves and other organisations, support for TLS comes as standard on the Email Gateway. If you need a bit more, we support international standards for OpenPGP and S/MIME message formats, enabling communications between recipients who use standard email clients such as Outlook, Outlook Express and Notes. Finally, our portal-based encryption is an easy-to-use method requiring no user knowledge of encryption. Encrypted messages sent using the Secure Encryption Portal can be opened on all types of devices, from PCs to phones and tablets. 3
Management The SECURE Email Gateway has been designed to reduce management costs. Application updates, including any operating system patches, are automatically downloaded onto the system and applied by the customer at their convenience. By using a hardened Linux operating system, customers may only have to apply a patch once or twice a year. For day-to-day management, the Gateway supports multiple administrators with different associated privileges. This enables specific tasks to be completed such as message management, reporting or monitoring without the risk of settings being accidentally changed. In addition, the logical user interface means that business managers can be involved in message workflow when violations occur. Message management is simplified using separate quarantine areas for each violation, coupled with different admin roles, meaning that sensitive messages can only be managed by senior administrators. Reporting Built-in reports for operational aspects of the system, such as message volumes, spam, viruses, latency and policy violations can be tailored on demand. Reports can be generated in HTML, PDF or CSV format, and can also be schedule to run and be emailed to appropriate recipients - saving on operator intervention. Reporting is consolidated across all members of a peer group to reduce the overhead of having to run the same report on each gateway. The system also incorporates a message tracking feature that enables administrators to find messages using an advanced search interface. They can find messages that have been received or rejected, and display the exact history of how the message was received, processed and disposed of. Personal Message Manager (PMM) Clearswift takes the management of blocked messages to an enhanced level, empowering the right users to manage their own violations. For example, a senior partner sending a large, urgent message late on a Friday night could find it triggering the Maximum Size Rule. Often the partner has no choice but to track down someone in IT to release the message. The PMM eliminates this problem, allowing you to define who can release what violations. The process is fully audited, with logs and email notifications if required. Where the system is used for spam management, a secure browser interface with single sign on permits users to safely read messages and decide whether they want to receive them. For users who need to manage their mail on the move, the PMM Mobile Client interface for iphone and ipad is available from the itunes App Store.
