CloudPassage Has Your Cloud Security Needs Covered

Wednesday, January 26th, 2011 by jrajani

CloudPassage has developed products built specifically to provide multiple layers of security for cloud servers. “Servers in the cloud need to be self-protecting and autonomous to survive the higher exposure level to threats and vulnerabilities,” said Srivats Sampath, founder and former CEO of McAfee.com, and an investor in CloudPassage. “Elastic cloud security from CloudPassage is the go-to-security solution for any organization that needs to scale and secure cloud servers.”

“Customers of our on-demand, enterprise-level email and social media marketing solutions have high standards for protecting their data and supporting their compliance needs,” said Tim McQuillen CIO and co-founder of StrongMail.  “CloudPassage allows us to clearly communicate in exact technical terms how we secure our environments and deliver compliance verification as frequently as needed.”

The ability to create new servers in the cloud within seconds means IT departments can be faster and more agile, but it creates huge security problems.  New copies of servers will duplicate all of the vulnerabilities and exposures that already exist, resulting in an increased attackable surface area on a company’s cloud server farm.

“Other server protection solutions that work in public clouds require painful deployment and management contortions,” said Carson Sweet, co-founder and CEO CloudPassage. “Because dozens of new servers can be created in seconds, through cloning and bursting, vulnerability and firewalling need to be done differently in the cloud; they need to be elastic.”

If there is a compromise on a normal server it can be prevented through configuration changes, software patches and improving firewall policies. In the cloud server model changes are difficult to manage as vulnerability management and firewall configuration has to be managed on each individual cloned or bursted server.

CloudPassage technology is built from the ground up to provide elastic security by automatically securing cloud servers when they burst or are cloned. Once security is set up on one server, all copies of that server created later will automatically adopt those security controls.  CloudPassage customers benefit from greatly reduced attack surfaces, lower risk of compromise and improved compliance.

Yes IT Administrator You Can Defragment Your Virtual Environment

Thursday, August 12th, 2010 by jrajani

Virtualization has become a popular IT tactic which leads to significant cost savings and time to deployment for various infrastucture needs. A key hurdle in the virtualization is the issue of fragmentation, the process can lead to reduced system performance and overtime effect the physical disk storing the virutal environment.

Vlocity 2.0 is a virtual platform disk optimizer software solution that works in the background to deliver defragmentation services for systems running on VMware ESX and Microsoft Hyper-V platform. The software solution incorporates IntelliWrite technology that writes files to disk and can prevent upto 85% defragmentation from occuring before it happens.

The solution was created as a virtual-specific product and not only does it perform defragmentation functions but also syncs activity between host and multiple operating systems deployed in a virtual environment. This activity can be configured on any type of setup including a high powered system with data storage occuring in a SAN setup.

“We deployed V-locity very shortly after deploying our virtual infrastructure, so there wasn’t much time for any bottlenecks to develop. We run V-locity on every Hyper-V virtual machine since it’s free with our license for the Hyper-V hosts. We did that mostly just to avoid the double defragmentation that can happen with virtual hard disks. We’ve also got it on a physical Exchange hub transport server (and another one that is virtual) mostly to keep the log files intact. The e-mail data is only on the hub transport servers temporarily during transit, but the log files change constantly. It’s also on the Exchange mailbox server to defragment about eight stores, almost all being over 100GB, and our main file share cluster. Both of those servers store their data on an HP SAN,” stated Eric Johnson from a Construction Industry site.

“The need for defragmentation is especially acute in virtual environments,” said Michael Materie, Product Management Director, Diskeeper Corporation. “Because physical hardware in a virtualized storage environment must support more operating systems and can undergo even more disk access and more stress than in a non-virtualized environment, fragmentation of these unique environments requires a specialized approach. With V-locity 2.0, users can realize the benefits of full virtual efficiency.”

Want Access to the Full Web? There finally is an app for that

AlwaysonPC has introduced a virtual PC app for the iPad and Android platforms that is packed with 40 pre-installed programs such as a mobile office suite and Firefox. The app delivers a productivity suite that can open common file types such as Word (.doc and docx), Excel (.xls and xlsx) as well as Powerpoint (.ppt, .pptx), etc.

Lack of flash on the iPad has been a major disappintment for most users and with this app users are now able to have access to a flash player with Firefox. The app does not support audio or video via flash, but the company has plans on improvements and upgrades over the lifecycle of the app.

The app uses an encrypted SSH connection to and from all devices. Users are provided solid security and high performance for common tasks. For example users can open large files, such as PDF files, PowerPoint decks or Excel Spreadsheets of 100Mb or more from an uploaded file, email attachment or an online storage folder such as Dropbox up to ten times faster than competing mobile solutions.

Most functions supported by a desktop environment are now available to tablet users, these include:

Copy and paste text & graphics between apps like Office, Firefox, email, & photos
Add browser toolbars like Google or Yahoo!
Click to open email attachments directly into the office or imaging apps
Multi-task: run multiple Office apps, email, IM and browser tabs and windows at once
Install Firefox Addons (a customer favorite is xMarks, which syncs passwords and bookmarks between the desktop PC and AlwaysOnPC, letting you browse without typing from your phone!)
Dropbox folder included- just login! (Other online storage services can be accessed via Firefox)
Image editing and Vector-graphic drawing programs
Games like Chess, Blackjack, Majongg, Sudoku & more
2 GB of online storage

AlwaysOnPC is available today in the iTunes Appstore as two applications (one for iPad, one for iPhone/iPod-touch), and in the Android Marketplace in the Productivity category for a special introductory price of $9.99.

Here’s a demonstration video for the app:
