On Messing Up…and Bouncing Back
BlackBerry used to be the dominant mobile messaging platform in the enterprise, but (by their own admission) they become arrogant as the market leader in the absence of serious competition.

Some Thoughts from EMC World
I spent some time at EMC World last week in Las Vegas. As always, it was time well spent in informative sessions and in individual meetings – and, gauging by the difficulty of traversing the hallways between sessions and after keynotes, the show was very well attended.

The Evolution of Cloud Data Management
We have contended for some time that many organizations will migrate to a hybrid of on-premises and cloud infrastructure for many of their key systems, such as email, archiving, security, etc. While migrating completely to the cloud for things like archiving is quite feasible and the right decision for many companies, some decision makers want […]

The Benefit of Confusion
Gleaned from a Web search this morning: “I have a data stream that will be sent as daily emails containing temperature and wind speed from a measurement site. Our email system is Outlook…” “We are a GroupWise 6.5.5 shop. We have a new employee who will start work in 3 weeks whose current email system […]

Longline fishing is a commercial fishing technique in which a main line of up to several miles in length contains hundreds or thousands of short lines with hooks, each loaded with their own bait.

Employees are Part of Your Security Infrastructure, Too
Most will agree that despite the enormous amounts spent on secure Web gateways, anti-virus software, cloud-based malware filtering and the like, users are still the weak link in the security chain. The primary reason for this is that increasingly they are the targets, often supplying the bad guys with the information they need by posting […]

The Growing Success of DMARC
Domain-based Message Authentication, Reporting and Conformance (DMARC) is a relatively simple authentication method designed to combat the growing problem of spoofed emails, particularly those that are designed to fool receivers who are the targets of cybercriminals. Using DMARC, a sender can indicate that any emails they send are protected by either the SPF and/or DKIM […]
