Introducing Defensio 2.0

Posted: 20 Jan 2010 04:00 PM | Defensio, the blog | no comments


Security for the Social Web After months of hard work, it is my extreme pleasure to introduce Defensio 2.0 - the first and only complete security suite for the social web . A number of new features now make Defensio the most advanced spam and malicious content detection service for the web. These features include: Spyware, malware, phishing and other types of malicious content detection URL blocking by category Profanity detection and filtering Script and executable blocking Enhanced statistics Asynchronous API (faster and non-blocking filtering) Thanks to Websense's Threat Seeker Network , Defensio can now detect and block much more than just spam , offering you the absolute best protection for your website. Screencast We prepared a screencast where you can see of the new Defensio 2.0 features. Wordpress The Wordpress plugin has been updated to leverage the new features we are introducing today. Upgrade today! Pixelpost Thanks to Dennis Mooibroek, Pixelpost now also supports Defensio 2.0. You can download the latest version of the Pixelpost plugin on our website . Facebook Protection A few months ago, we started noticing that a lot of spam, profanity, malware and malicious content was making it onto personal and corporate Facebook pages. We knew we had to do something about it. Our response to this growing problem is the first ever Facebook security suite. This is also launching today! Once Defensio for Facebook is installed, we will constantly monitor your page for possibly unwanted content. Should we find something suspicious, we will alert you. This Facebook application works with any kinds of pages, including personal and corporate profiles, group pages and fan pages. To install Defensio for Facebook, simply create an account at http://defensio.com/signup . If you already have a Defensio account, log in, then in the control panel, click "My API keys", then "Protect another web property". Other platforms More platforms will support 2.0 very soon. Defensio 1.x remains available and software using our old API will keep working as usual. New Developer API We love our developers, and we made sure not to leave them out in the cold. Defensio 2.0 ships with a brand new and improved asynchronous RESTful API! The new API features: Asynchronous (or synchronous) for fast, non-blocking calls to Defensio Optional web hook for asynchronous calls Entirely RESTful More generic wording, making it less targeted towards blogs and easier to use in a wider range of web applications New actions for profanity filtering and enhanced statistics Content classification (spam, malicious, innocent) See the API 2.0 documentation for more details. We're also releasing many 2.0-ready developer libraries for PHP, Ruby, Python and Perl. This should make your life easier when upgrading your application to Defensio 2.0. You can find them in the "downloads" section of our website . Conclusion I hope you're as excited as we are about the second coming of Defensio. Let us know what you think!

If you think image spam is elaborate, think again! At Defensio, we see all kinds of crazy and innovative spam each day. But recently, something we never thought we'd ever see showed up on our radar: a significant influx of VIDEO spam, most of it hosted on YouTube.com . I guess this just shows how far spammers are ready to go to sell their junk. Here's a screenshot... What do you think will be the next trend in spam?

This morning, hosted e-commerce solution Shopify enabled commenting on its users' blogs . After comparing the many spam filtering services available, the Ottawa-based firm decided to use Defensio as their first line of defense. This is yet another great step for us since Shopify currently hosts ~40,000 blogs. Shopify launched in mid-2006 and was greatly acclaimed . Building an online store with Shopify couldn't be easier and many believe they are a great contender to overtake eBay 's dominance in this market. Shopify recently announced they passed $10M in total sales .
