Ultimate Remote Team Collaboration Server For 0€


One of the most challenging problems for remote team is how to establish secure way of communication and collaboration. There are a lot of proprietary software packages for remote team collaboration, but the goal of this article is to list number of open-source packages which can be used to build the ultimate collaboration server.

1. Active Directory – OpenLDAP – 0

The Lightweight Directory Access Protocol is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network. As examples, directory services may provide any organized set of records, often with a hierarchical structure, such as a corporate email directory. Similarly, a telephone directory is a list of subscribers with an address and a phone number.

Software feature includes:

  1. LDAPv3 Support — OpenLDAP supports Simple Authentication and Security Layer (SASL), Transport Layer Security (TLS), and Secure Sockets Layer (SSL), among other improvements. Many of the changes in the protocol since LDAPv2 are designed to make LDAP more secure.
  2. IPv6 Support — OpenLDAP supports the next generation Internet Protocol version 6.
  3. LDAP Over IPC — OpenLDAP can communicate within a system using interprocess communication (IPC). This enhances security by eliminating the need to communicate over a network.
  4. Updated C API — Improves the way programmers can connect to and use LDAP directory servers.
  5. LDIFv1 Support — Provides full compliance with the LDAP Data Interchange Format (LDIF) version 1.
  6. Enhanced Stand-Alone LDAP Server — Includes an updated access control system, thread pooling, better tools, and much more.
Operating system : Red Hat Enterprise Linux, CentOS, Debian, Ubuntu, FreeBSD, and OpenBSD

4. Video Conferencing – Jitsi – 0

Jitsi is a set of open-source projects that allows you to easily build and deploy secure videoconferencing solutions. At the heart of Jitsi are Jitsi Videobridge and Jitsi Meet, which let you have conferences on the internet, while other projects in the community enable other features such as audio, dial-in, recording, and simulcasting.

Software feature includes:

  1. Unlike other videoconferencing technologies, Jitsi Videobridge, the heart of Jitsi, passes everyone’s video and audio to all participants, rather than mixing them first.
  2. The result is lower latency, better quality and, if you are running your own service, a much more scalable and inexpensive solution.
  3. Jitsi is compatible with WebRTC, the open standard for Web communication.
  4. Jitsi supports advanced video routing concepts such as simulcast, bandwidth estimations, scalable video coding and many others.
  5. Jitsi is written in Java and some native code.

6. Server Security – EvoWall – 0

EvoWall changes the way teams can work together. Current best security policies involve strong passwords, two or multifactor factor identification and heavy use of VPN solutions. Thеse solutions are good enough, but do not provide multilayer defense system. Most of the time when first layer of defense is bypassed internal network does not have additional security mechanisms and attacker can sniff network packets and scan devices for open ports and early day exploits without problems.

EvoWall is designed with these problems in mind, so our solution enhances existing firewall solutios by adding finer access and denial control. Main problem of current firewall defense approach is that most of the time ports are either open for all users or are closed at all. And what happens if we have remote workers, that change their location often? Or you have to access company network during presentation, business meetting or demo? Or you want to give your clients access to internal resources, without giving them access to the whole network? Or you want to open server port for external application only.

Software feature includes:

  1. Multiple OS support
    Linux, Windows, Mac OS, Android, iOS(TBD) client support.
    Firewalld, UFW, Windows(TBD) firewall support.
  2. Secure
    AES encryption, Distributed, HtAccess, 500 000 unique unlocking keys
    Obfuscated binaries and encrypted data
  3. Low memory footprint
    20 MB memory usage of unlocker
    50 MB memory usage of server opener
  4. Simple API
    Setup and generate unlocker and opener for under 180 seconds
    Fast and easy port and protocol type rules management
  5. Effective
    Prevent port and zero day exploits scanning
    Effectively restricts access to critical resources
  6. Universal
    Can be used in multiple security use cases
    Server protection, client protection, zero days exploits protection, resources restriction, access monitoring
  7. Easy deployable
    Can be deployed in various enviroments – clouds, backbone servers, private datacenters
    Use standard opensource highly tested software as base
  8. Easy to integrate
