A central promise of our Managed Spam Filter Services is to protect our customers from malicious mails. Especially the automatic detection of spam and malicious software has rapidly gained importance in recent months – Locky, Tesla, Petya and co. send their regards! The Content Filter is an additional, customizable protection. Customers can use it to independently control the handling of attachments contained in incoming and outgoing emails. The maximum file size for attachments can thus be set – although the Content Filter’s ability to detect certain types of file extensions is much more important. This allows administrators to define specific file extensions, thus preventing the delivery of an email with the relevant attachment.Specifically, this means: If an IT manager wants to prevent their email users from receiving attachments with the .exe extension, they need only enable the Content Filter (if not already activated) and enter .exe into the open field. As a special service and for ease of use, we have set up several group extensions to provide improved protection in all the default settings: .executable, .mediafile, .xlsmacro and .docmacro. If, for example, “.executable” is specified, the Content Filter automatically blocks 58 extensions of executable files. This group extension is continuously maintained and kept up to date in order to always ensure the highest possible protection. The extension .mediafile, for example, can be used to filter out files with the extensions .wav, .mp3, .mid. mpg and several others. The two other collective terms are specifically designed to retain macros in Excel and Word files, which often transmit links to blackmailer viruses. The Content Filter can incidentally be configured for the entire domain as well as for specific groups within a domain. If not already enabled, we thus urgently advise all customers and partners of Hornetsecurity to activate the Content Filter free of charge and add the file extension “.executable” to their list of files to be blocked. They can ramp up their protection another notch by doing so. The screenshot shows how this is done. Note: This blog post was first published in April 2015 and has now been updated and adapted to the new ransomware threats.
A central feature of Hornetdrive is the smooth, quick exchange of files between users. The company GROHE found an interesting use for the centralized control and distribution of its marketing materials to showrooms and sales representatives. INITIAL SITUATION GROHE, a leading German manufacturer of sanitary fittings, equips several showrooms with an iPad as part of a project. In addition to marketing videos and product information, it also provides selling points to guide the staff working in the showrooms. Several sales representatives also own iPads for their professional activities. Marketing materials had traditionally been provided via an enterprise application on the mobile devices. The problem: This software required an Apple license that had to be renewed annually and could only be installed by GROHE itself. The company thus had to collect all the iPads once a year to install a new version of the materials and the app and then send them back to the showrooms. It was thus impossible to make spontaneous changes to the product information. To put an end to this complicated and time-consuming procedure, GROHE looked for an alternative. SOLUTION With Hornetdrive, digital content can be distributed within seconds – to computers and mobile devices anywhere in the world with an internet connection. The user first loads all the files to be distributed onto the Hornetdrive cloud, from where they are then automatically synchronized with all access-authorized devices. For people who are not members of the respective drives and therefore do not have permission to access the data, the files are useless because they are encrypted locally before uploading. Multi-rights management can be used to assign users different permissions, facilitating easy control of the content’s usage and editing. The German company Hornetsecurity – the provider of Hornetdrive – operates the service exclusively in German data centers and in compliance with the German Data Protection Act. RESULT In Hornetdrive, GROHE found a service that allowed the company to distribute its marketing information to the iPads of its showrooms quickly and easily, without the bothersome annual recall of iPads. All showrooms with internet access can now install Hornetdrive, and then GROHE invites them to use the drives in which the content is found. At the same time, they are given a “read only” authorization, so that they cannot change or delete content and GROHE thus keep the control over product videos, data sheets, and so on. The company can also control updating of the materials from a central location – it simply inserts a new file into the drive and the iPads are immediately synchronized and brought up to date. And GROHE was satisfied with Hornetsecurity as a German provider because the data is fully encrypted and this is done in Germany.
