  The When, Where and How of Cisco versus Microsoft for Unified Communications by Zeus Kerravala

  Earlier this week I was at a CIO conference in Europe and one of the big topics of conversation was Unified Communications. Remote working, collaboration initiatives and cost cutting have all made UC a more important topic over the past twelve months. There was lots of discussion about deployment issues, the ROI of UC, training issues, etc. but the biggest point of discussion was Cisco versus Microsoft and where to use which. Based on the conversations I had at the CIO summit plus others,...

  Anticipating the RSA Conference 2012 by Jon Oltsik

  It’s now February although you’d never know it from the balmy winter here in Boston. Aside from Valentine’s Day, February is significant because it is when security geeks from around the world get together in San Francisco for the RSA Conference. The show doesn’t start until 2/27 but you can feel the anticipation in the air across the whole security community. That’s a good thing since 2011 was an especially difficult year – some have even labeled it, “the year of the breach.” Hmm, what...

  F5 Shakes Up the Firewall Market by Jon Oltsik

  The high-end of the firewall market has really been dominated by two companies: Crossbeam Systems (with Check Point Software) and Juniper Networks. Over the past few years, these two firms won most of the high revenue/high margin enterprise and service provider deals. Of course, others took notice and wanted their own piece of the pie.

  Cybersecurity Lessons from the Battlefields of Europe by Jon Oltsik

  At the beginning of WWI, battlefield tactics had not advanced much since the U.S. Civil War. The general goal was to continually advance on the enemy with waves of infantry attacks and eventually break through the lines by overwhelming enemy defenses. It didn’t take long until both sides realized that things had changed. With the invention of the water-cooled machine gun and pill box fortification, human waves were not only ineffective; but also resulted in mass casualties. The sides...

  My Thoughts on IBM, NEC, and OpenFlow by Jon Oltsik

  IBM and NEC announced this week that the two companies will work together to offer networking solutions based upon SDN and OpenFlow. IBM provides the switches which are integrated with the NEC Programmable Flow Controller. To me, this is bigger than just a press release and some joint marketing programs. Here’s why: 1. IBM and NEC are moving OpenFlow beyond academic labs and cloud computing theory, taking their joint solution to enterprise data centers. Yes, enterprises need to be...
