KoMnA Server is a software platform, designed specifically for our servers. It's based on the OpenBSD operating system with custom configuration and additional server software, as well as application solutions developed in-house. These days, our servers mostly run on PC architectures (i386, amd64), some SPARC (Sun UltraSPARC) or (rarely) MacPPC (Apple PowerPC).
The server is primarily used for our company's needs and for hosting of our solutions. It can be configured for all other needs of our clients, such as firewall, mail server, file server, authentication server or as a backup server. We ensure rapid deployment, training of users and good maintenance.
Mail server KoMnA enables the client complete control over their e-mail and the highest possible level of security and privacy of messages. The server enables:
sending and receiving e-mails for one or more domains, with support for SMTP, POP3 and IMAP with SSL (SMTPS, POP3S, IMAPS) and TLS encryption,
antivirus protection with enabled inspection of the content of archive files (zip, tar, tar.gz, RAR, ARJ, CAB, ...),
protection against unwanted messages (filtering, grey and black lists, message analysis) with the option of archiving intercepted messages,
access to mailboxes through a web interface (webmail),
user groups with per group rules,
access to the administration interface via web (webadmin), with group management and management of features and server settings,
mailbox size limit and allowed or disallowed attachments (screening of compressed files) in messages for individual groups,
automatic user notification of exceeded limits,
archive of all messages that pass through the server and controlled access to the archives,
additional options such as archiving to remote locations, SMS notification of received messages, traffic surveys, analysis of links between senders and recipients, etc.
Data server enables storage of your data in the local area network (NAS – Network-attached storage) via the SMB/CIFS and NFS protocols) or on the Internet (FTP, HTTP/HTTPS, or SSH. SFTP, VPN connections), with simultaneous access for multiple users.
Additional options are strict access control, automatic backup, separate access for customers or the public, electronic document signing with time stamping, revision control, etc.
We also offer installation and maintenance of firewalls with packet filters and various proxy servers. Such services are usually implemented as a part of an overall threat analysis or implementation of company wide security policy that consists of:
server and local network protection,
Web content filtering, filtering of instant messaging programs and file sharing systems,
rules based on passive detection of operating systems,
other special settings requested by the customer.
With selecting firewall hardware, special emphasis is given to the quality of network interfaces. All our firewalls (without exception) and other security servers are OpenBSD based and have never been a target of any successful attacks.
