Israel-based startup Porticor launches this week with technology aimed at
giving enterprises a way to encrypt data held in cloud computing services,
including those from Amazon and Rackspace.
Porticor Virtual Private Data is focused on protecting data at rest in
cloud-based computing centers where customers rent disk space or servers,
says Gilad Parann-Nissany, Porticor’s co-founder and CEO. What Porticor is
doing that’s distinct is relying on a so-called “split-key” method in
which the service to encrypt and decrypt doesn’t work unless both pieces of
the key are together.
The enterprise customer holds what Porticor calls the “master key,” and
the idea is to foster trust by putting the customer in complete control.
“We don’t have the customer master key,” says Parann-Nissany. In fact,
the service provider doesn’t even see the master key in the encryption
method th... (more)
As part of our cloud strategy, we’ve recently released a VMware version of
our cloud security offering. It allows cloud providers using VMware, as well
as the cloud users themselves, to create an encrypted environment within
minutes, while eliminating the complexity around encryption key management in
the cloud without compromising trust and confidentiality.
During this process we’ve engaged in many conversations with the cloud
providers’ community to better understand their requirements, and equally
important – their customers’ requirements. We’ve identified some
interesting pa... (more)
Secure cloud backup is a scenario which increasingly gains traction. It
allows organizations to implement an off-site backup while maintaining costs
at a minimum. In this blog post I would like to focus on a specific use case
of secure cloud backup. The system we describe is comprised of an on-premise
replication server, Porticor Cloud Security, and Amazon S3 as the final
backup destination, all integrated by one of our fine cloud integrators.
Secure Cloud Backup – The Business Need
In this use case, an enterprise organization was struggling with an
inefficient and costly offsite... (more)

Over the past year, the trend of developing and delivering a software
offering over a public cloud such as Amazon Web Services has grown
dramatically. Software Vendors, both established and start-up companies, are
using Infrastructure as a Service for its obvious advantages, such as cost
effectiveness, redundancy, high availability, and probably the most dramatic
effect for a software vendor – flexibility. A software vendor can make use
of the IaaS provided APIs to automatically add servers, disks, back... (more)
Recently, in our post on Database security in the cloud, we reviewed the
threats against database installations in the cloud and best practices for
protecting your data. A number of customers have asked us follow-on
Which database brands are open and tested with these techniques? What are the
most significant gotchas? What performance, scalability and fail-safe
characteristics can they expect when securing their database in the cloud?
We have found that all the major relational database brands (MySQL, Oracle,
Microsoft SQL Server, and IBM DB2, among others) can work wel... (more)
