Kerio Connect – The Exchange Alternative

Microsoft Exchange – the 1,000 lb Gorilla

Microsoft Exchange is powerful software, but it has its place – in the enterprise. Microsoft Exchange is an enterprise-class messaging and collaboration server and along with it comes expensive hardware, overly complex administration and excessive IT overhead.

But what about Small Business Server (aka SBS) you ask? While it sounds like it’s intended for smaller organizations, don’t be fooled. SBS is marketing at its best – an enterprise-class product merely packaged, priced, and positioned for the small business market.

Whether Exchange or Small Business Server, it’s overkill and it requires far too much resource investment for many of today’s medium and small businesses like yours.


What makes Kerio Connect different

Kerio Connect on the other hand is engineered to address the needs of the work horses of today’s economy – businesses like yours. We focus on solving your IT needs, so IT doesn’t get in the way of your business.

As a result, we’ve done away with the complexity, overhead and excessive costs, and focused on building the world’s best and most flexible messaging and collaboration server for you, at a total cost of ownership you won’t even think about.

When you compare the hardware requirements, operating system requirements and licensing costs alone, without a doubt, Kerio Connect is the clear winner.

6 reasons why businesses, IT Consultants and VARs choose Kerio Connect over Exchange :

1. Lean.  Everything Exchange does, without the IT overhead
2. Flexible.  Deploy on Windows, Linux, Mac, VMware, Parallels or HyperV
3. Mobile. Broader mobile device support – sync public folders, shared calendars and contacts
4. Stable.  Focus on your business – not on downtime and unexpected costs
5. Simple.  Set-up, administration, and maintenance is a breeze
6. Value.  Lower licensing costs, lower hardware requirements, lower service costs

always connected

advanced email protection

Email Security

SSL Encrypted Secure Communications

Kerio Connect protects corporate information with strong SSL encryption on all inbound and outbound email. Whether accessing Kerio Connect from a web browser, mobile device or desktop client such as Outlook, every connection and communication is encrypted, preventing outsiders from capturing passwords and accessing email content.

S/MIME Security even on iOS 5 Devices

With support for Secure MIME (S/MIME) in most email clients, including iOS 5 devices configured using Exchange ActiveSync, Kerio Connect extends its high level security to your mobile team. Using a S/MIME supported client or device, rest assured that sender/receiver identity is authentic, and that email content and attachments are locked down in case a message falls into the wrong hands.

Robust Anti-Spam Protection

Is your inbox inundated with junk e-mail? Spam isn’t just an annoyance, it can pose a serious security threat to your organization’s network. The built-in Anti-Spam engine in Kerio Connect rids your inbox from all that un-wanted, and potentially malicious email. Protect from Directory Harvest Attacks (DHA), phishing and spoofing with Bayesian, Heuristic and SURBL spam filtering techniques, Internet blacklist servers, custom whitelists and blacklists, greylisting cloud service, SMTP restrictions and more.

Sophos Anti-Virus Protection

The integrated Sophos Anti-Virus engine in Kerio Connect seamlessly protects your network from viruses, Trojans, worms, spyware and adware commonly piggy-backed on email traffic. One of the most efficient virus scanning engines available, Sophos Anti-Virus catches all malware in a single scan and automatically guards against zero-day threats with minimum impact on memory and system performance.

Password Guessing Protection

Kerio Connect gives administrators granular control over protecting users from outside attackers attempting to guess weak passwords. Block IP addresses suspicious of account and password guessing attacks, block user accounts that have been targeted by password guessing attacks, or even specify to never block password guessing attempts from local clients if you have some forgetful users.


Server Backup and Data Recovery

With Kerio Connect, you’re protected in the event of a hardware failure and from users inadvertently deleting email. Administrators can schedule full or differential message store backups to automatically run on specified days and times, without taking the server off-line. Receive email notifications when backup has completed, or if there were any interruptions.

Easily restore server configurations and user data onto a new server, or integrate with third-party high availability solutions for maximum uptime. And when you need to recover emails from a users emptied deleted items, no problem. You’ll have them back in just a few clicks.


Archiving for Compliance and Governance

The built-in email archiving feature in Kerio Connect allows organizations to capture and store all incoming, outgoing and relayed messages for both local and remote sender/recipients. Whether regulated by one of the many governing bodies or simply want to maintain an email archive for potential legal discovery, Kerio Connect makes it easy for all organizations to follow archiving best practices.

Administrators can choose to archive on-premise to a local archive directory, or easily integrate with third-party archiving solutions and non-rewriteable media for legal compliance. Use Kerio Connect client for search of on-premise archive, or use a third party legal discovery service for more robust search and audit.

Retention Policy

Don’t let mail hoarders consume all your storage space. Flexible retention policy options allow administrators to create policies to automatically delete old email items. Configure policies by domain or by individual user, select which folders to include in the policy, and set the age of items to be deleted in days or years.



Whether businesses need total control over their mail server, or they simply want reliable full-featured email service, Kerio Connect offers the broadest deployment options and the widest client side access available.

On Premise

Kerio believes in freedom of choice. Whatever your rationale, if you choose an on-premise deployment, we’ve got you covered. Whether you run Windows, Mac, Linux or a virtualized environment in the back office, there is a Kerio Connect installation package available for the host OS or hyper visor to suit your needs.

In the Cloud

You’ve decided the cloud is right for you, but which cloud email service makes the most sense? Most cloud services today are public. Kerio takes a slightly different approach to cloud email, offering both shared and private cloud environments, both available as a pay-as-you-go service through Kerio’s partner network.

Supported Clients

Need a mail server as dynamic as your organization? Kerio Connect works seamlessly with the desktop clients that your teams use. Your marketing team uses Apple Mail and Outlook for Mac, but your sales and accounting teams use Outlook on PCs? No problem. Kerio Connect works with them all. Use Outlook at the office but don’t have Outlook at home? No Problem. Access your email and manage your appointments with the newly designed Kerio Connect client from any browser.



Kerio Connect’s fully functional web-based administration interface lets you easily configure your mail server settings no matter which deployment option you choose. And with the iPad optimized web admin interface you can fully manage the server from virtually anywhere.

Tackle routine tasks like reset a user’s Password or send/clear Message Queue items from the coffee shop. Or create and apply User Access Policies, tweak Spam Filter settings, or browse logs to troubleshoot the mail server with ease from your son’s ball game. With multi-gesture support, scroll logs faster with multiple fingers, two-finger tap to get contextual menus, and toggle to hide the menu tree to maximize screen real estate.



With simplicity as one of our core values, we want to make switching to Kerio Connect as fast, easy, and painless as possible. Whether you’re migrating from an Exchange environment, an IMAP environment, or something else, check out the free migration tools we have available.
