Reliable Networks is pleased to host the April meeting of the New England ISO group, a collaborative group of Information Security Officers and Chief Security Officers from New England enterprises.

During the meeting, I will be sharing our best practices regarding email server security. The talk will be less bits ‘n bytes technical (no procmail rulesets for example!) than it will be strategic; intended to provide ISOs with both a framework and a template for securing email systems.

Malware infestations typically penetrate enterprises through web browsing and email payloads. While there is no substitute for good end-user security training, there are some things which can be done on the email server-side of things to mitigate risk, at reasonable cost, and without inconveniencing end users unduly.

NEISO meeting attendance by non-members is by invitation, so if you would like to come, please follow the link on the NEISO website.

Hope to see you there!

All the best,

Zimbra is a fast-growing competitor to Microsoft Exchange with more than 55 million paid mailboxes globally and some multiple of that in free mailboxes provided via their unpaid open source version. Full Disclosure: More than two years ago we chose Zimbra for our own use, and soon thereafter became a Zimbra Premiere hosting provider.

We don’t play favorites here at Reliable Networks, and we think Exchange 2007 and Exchange 2010 are very good products, much improved over Exchange 2003 and earlier versions. We support Exchange at our clients as well as Zimbra; which platform they choose is based on each client’s unique needs.

VMware is now headed by Paul Maritz, who many pundits feel left Microsoft in a “three’s a crowd” situation nearly a decade ago.

Zimbra has been taking away some very big Exchange accounts from Microsoft since being acquired by Yahoo, and we expect that trend will accelerate with Zimbra now under the VMware umbrella.

So the good news for clients is that, when it comes time to upgrade your old Microsoft Exchange installation, you now have more interesting options than you did yesterday.

And watching the action as VMware and Microsoft compete on this new front, at least to techo-heads like us, is more entertaining than a new season of American Idol!

If you have questions about your email/collaboration choices, give us a call at (207) 772-5678. Zimbra isn’t for everyone, but neither is Exchange. We’ll help you make the choice that’s right for your company.

All the best,

Over the past year we have helped a number of our clients reduce their costs and improve reliability by getting rid of premises-based servers in favor of hosted services (e.g. Drop Box for file sharing) and/or data center hosting for mission-critical vertical applications.

Once the servers go off site however, the office’s connection to the Internet becomes the “weak link in the chain.” Some clients attacked that link by swapping out their current Internet connection for a more enterprise-grade connection (e.g. SDSL or bonded T-1s), but that still represents a single point of failure. Other clients upgraded their router/firewall to a device that can load balance or failover between two simultaneously active Internet connections. So when the cable modem service is down, the router automagically switches over to the DSL connection — totally seamlessly to the end users. Some router/firewalls even allow you to use one of those Sprint/Verizon Wireless PC Cards traveling laptop users have for the office’s secondary Internet connection. Which mix of redundant connections to use is a complex matter, requiring careful analysis of not only your bandwidth usage as a whole, but the workflow processes utilized by your employees, customers, vendors and others with whom you connect over the Internet, even if only by email.

As the Commonwealth of Virginia has discovered, not having any redundant Internet connectivity, even when using so-called “bulletproof” network connections, is just not acceptable. (You can read the story here.)

Consequently, we find our clients’ businesses increasingly require a conversation about the merits and costs of redundant Internet connectivity. For increasing numbers of clients, redundant Internet connectivity is no longer a luxury; rather, it is very cheap insurance if not a necessity.

If you need help deciding if redundant Internet connectivity is appropriate for your business, please feel free to give us a call at (207) 772-5678.
