Email security

SSL Encrypted
Secure Communications

Kerio Connect protects corporate information with strong SSL encryption on all inbound and outbound emails. 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, be 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 organisation'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, 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.
