Frisbee
FAQ
General questions
What is Frisbee?
Frisbee is a corporate messenger, a secure platform for users to work together in government organizations. Compared to conventional messengers, Frisbee increases security and transparency of enterprise communications. Frisbee uses Big Data technologies to accumulate, structure and index the corporate knowledge base.
Which functions does Frisbee provide?
  • State-of-the-art user interface on all platforms, full replacement of Telegram and Skype
  • Organized communication in workspaces and chat rooms (channels)
  • Personal and group communications: messages, audio calls, video calls (soon)
  • Unlimited message history with documents and photos
  • Instant search across all chats, no matter how deep the archive is.
  • Centralized account administration and other resources
  • High fault tolerance, no points of failure
  • Integration with organization' IT services (employee directory, SIP telephony, etc.)
  • Ability to connect guest users (soon)
What is the difference between Frisbee and its analogs?
Frisbee is more suitable for government organizations due to the following features:
  • Frisbee uses customizable encryption algorithms. It's GDPR-compliant.
  • Frisbee can be deployed on the customer's server equipment or in a trusted data center.The analogues (Microsoft Teams or Slack) cannot be installed on-premise and stores all the information in their own data-centers.
  • Frisbee supplies the entire infrastructure for private cloud and cyber security. These components meet the same transparency and security requirements as the messenger itself. The customer gets a complete solution without additional costs for third-party software and certification. Analogues (Mattermost, Express) provide additional costs for deploying and maintaining virtualization software (Openshift, vmWare) on the customer's or service provider's equipment.
  • Frisbee allows you to change the appearance of the messenger for the customer or service provider (logo, name, basic colors).
Why Email should be replaced with a corporate messenger
  • In Email, all e-mails fall into one box, there is no separation by projects and tasks. You cannot disable notifications for a non-priority group of emails.
  • In Email, dialog is difficult to perceive, especially when there are many replies in a chain, it is difficult to communicate in real time.
  • Applications (documents) are often lost when replying or forwarding.
  • In Email, an employee may "drop out" of important correspondence if they forget to add it to a copy or click "Reply" instead of "Reply to all".
  • In Email, you can't quickly call or organize a conference with the participants of correspondence.
Why are public messengers unsuitable for working correspondence?
Public messengers (Telegram, WhatsApp, etc.)

Data separation: No workspace separation, personal and business correspondence are mixed.

Management: User accounts and chat rooms are managed by individuals. After dismissal, the employee remains in the chat rooms and maintains access to the correspondence history.

Data storage and processing: The organization does NOT own the data. The messenger operator independently manages the physical location and depth of the message archive. Data are stored and processed on the territory of other states.

Integration: Opportunities for integration with organization' IT systems are limited. There is no centralized user management and storage of the message archive.

Corporate platforms (Frisbee, Mattermost, etc.)

Data separation: Communication is separated into workspaces. Each workspace isolates group chats and personal correspondence.

Management: User accounts and chat rooms are managed by authorized persons of the organization (administrators, management). On dismissal, an employee's account is blocked for all chats at once.

Data storage and processing: The organization owns the data and manages the depth of the message archive. The data are stored and processed on the customer's servers or by a trusted provider in the customer's country.

Integration: Ability to connect user directories (Active Directory, LDAP), SIP-gateway, document management systems, and other enterprise systems.
What is a workspace?
Frisbee workspace is a logical union of channels (chats) and personal correspondence. It is a convenient tool in terms of information space organization and data protection. For example, separate workspaces can be created for the organization as a whole, its departments and large projects. All users can see all open channels inside the workspace.Demonstration: https://youtu.be/YYMbKC5Jrg0
What types of channels (chats) does Frisbee support?
  • Open (public) channels: visible to all workspace users
  • Closed channels are visible only to invited workspace users
  • Special channels: Main, Various, Saved.
  • Auto addition: All existing space users as well as new users are automatically added to the channel.
  • Notification: A user manages notifications separately for each channel.
  • Message History: new users see all previous messages sent before this user joined the channel.

Is it possible to invite a guest users?
We are working on Frisbee functionality that will allow organizations to securely connect external collaborators to individual chats and group calls.
How can I test Frisbee?
You can create a workspace and invite your colleagues through Frisbee client applications or a web browser. This test copy of the Frisbee cluster is available in Google Cloud. Demonstration: https://youtu.be/YYMbKC5Jrg0
Architecture and scalability
On which devices is Frisbee available?
  • Mobile devices on Android and iOS
  • Workstations on Windows, MacOS and Linux
  • Browser (all Frisbee functionality is available without installing client applications)
Can a user work on several devices at once?
Yes, a user can work in Frisbee from multiple devices simultaneously. The number of user devices is unlimited.
Are there any limitations when scaling Frisbee?
No, there are no architectural restrictions on the number of users, workspaces, chat rooms, as well as the depth of the archive of indexed messages and the frequency of search queries.

Frisbee is a carrier-class platform with horizontal scaling for all parameters. Frisbee's supply includes the infrastructure for creating a private cloud on the customer's equipment.

The Frisbee architecture excludes components that may become bottlenecks when scaling a service. For example, some analogues use Elastic Search technology and relational database for message indexing. Frisbee uses fast indexing and search algorithms in a distributed Cassandra database.
What is the largest successful Frisbee implemantation?
11,000+ users (organization committee members and volunteers) worked in the Frisbee messenger during the II European Games 2019 with a peak load of over 1,000+ messages per second.
Is the Frisbee platform fault tolerant?
Yes, Frisbee is a carrier-class platform with multiple redundancy of all system components. Frisbee uses Kubernetes orchestration technology to automatically rebalance the load in case of failure of any of the system nodes (including between different data centers). Frisbee uses a distributed Cassandra database and software-defined Ceph file storage with three copies of all data.
Can a single Frisbee cluster serve multiple organizations?
Yes. Frisbee cluster is multi-tenant.
Is there a corporate file storage?
Yes, the Frisbee package includes the deployment and support of the Ceph software storage object network within the customer's private cloud. Frisbee provides unlimited storage for Ceph Storage Network applications (documents, images) through an S3 interface. Synesis is experienced in supporting large Ceph clusters of dozens of petabytes.
What are the requirements for the server hardware?
Requirements to the Frisbee server cluster are calculated upon request based on the following parameters:
  • Number of users
  • Depth of messages archive (months)
  • Integrations
Frisbee can be deployed on "cold hardware" (without software) or on virtual machines at the customer's premises, as well as at global cloud infrastructure providers, such as Google Cloud.
Security
How does Frisbee ensure confidentiality?
  • All Frisbee clusters regularly pass pentests to detect vulnerabilities, including the most dangerous ones from the OWASP Top 10 list (denial of service, administration hijacking, data leakage, changes in application and data composition).
  • When connecting a new device, the Frisbee user uses only one-time passwords (OTP), which minimizes the human factor.
  • When an employee is fired, the administrator can block the employee's account for all chat rooms and devices at once.
  • All data is encrypted using various algorithms.
  • Chat and user directories are distributed by workspaces. More confidential information can be placed in a separate space.
  • Frisbee transmits secure PUSH-notifications (without transmitting the content of messages to Google Play and Apple Store services).
  • The Frisbee cluster shall be placed on the customer's hardware or in a trusted data center of the customer's choice. Frisbee cluster may operate in a closed network loop.
  • Frisbee comes with the TheWall Cyber Security Platform, which includes a firewall, intrusion detection system and network filter.
  • The Frisbee source code can be provided to the authorized laboratories for the analysis of confidential correspondence (protection class KC1) and absence of undocumented opportunities.
Frisbee private cloud infrastructure software uses only open source components that have been tested by time and international experts.
What encryption means are used in Frisbee?
Frisbee allows you to select and configure encryption methods according to the legal requirements of the country and/or organization.
And unlike its analogues, Frisbee encrypts not only messages, but also streaming media (voice calls).
Can the Frisbee work in a closed network loop?
Yes, Frisbee works in a closed network loop:
  • The Frisbee cluster can be deployed in the local network on the customer's equipment. The main Frisbee services will work without Internet access.
  • Exception: services for delivery of PUSH-notifications on Android and iOS devices. To support these services you need to add simple rules to the corporate firewall. In this case, the content of sent messages is NOT transferred to the services of Google Play and Apple Store (safe PUSH-notifications).
What identification and authentication methods does Frisbee support?
  • The user is identified by e-mail address or cell phone number (user's choice).
  • User authentication is performed by sending a one-time password (OTP) to an e-mail address or via SMS to a cell phone. The user does not need to invent and remember a password.
Frisbee Integration
Does Frisbee have an open API?
Yes, Frisbee has an open REST API for embedding chat into customer applications and creating chat bots.
Is there integration with the user directory (Active Directory)?
Yes, Frisbee can synchronize with Active Directory and update the user card, including name, phone number, email, position.
Is there integration with VoIP/SIP gateways?
Routing voice calls (including group calls) from Frisbee to conventional phones can be implemented on demand through the corporate VoIP/SIP gateway.
Can I make chat bots for Frisbee? Any examples?
Yes, it is possible, for example, to implement chat bots that can:
  • One-click approval of internal documents
  • Voting (by analogy with Telegram)
  • Registration of badges, business trips, vacations, etc.

What is more convenient: chat bots, mobile applications or web portals?
Simple automation tasks, as in the example above, are effectively implemented on the basis of chat bots. It is easier to click a button in the chat room than to go to individual sites or open individual applications.
Which programming language you need to use to create chat bots for Frisbee?
Chat bots can be implemented in any programming language as the REST API interface does not depend on platform and development environment. Suitable languages are Python, JavaScript, .NET and others.
Analogues and competitors
What are the Frisbee analogs?
  • Competitors (widely used): Email, Telegram, WhatsApp, Skype for Business
  • International: Mattermost, Teams, Wire, Slack
How does Frisbee differ from its nearest competitors?
Frisbee is more suitable for government organizations due to the following features:

  • Frisbee encryption algorithms for voice calls and messages are highly customizable. That mean Frisbee can use encryption algorithms according your national standards. Most of the known analogues use American algorithms within the protocols TLS and WebRTC.
  • Frisbee can be deployed on customer's server equipment or in a trusted data center. Most of the analogues, such as Microsoft Teams or Telegram, residents the data in a data centers in a different countries. Using that analogues may bring a security risks.
  • Frisbee includes software infrastructure for creating a secure, resilient and scalable private cloud based on open source software. Frisbee does not require additional software for orchestration, virtualization, storage and cyber security. The customer gets a complete solution with no additional costs for third-party software. Our competitors offers an additional costs for deployment, certification and supporting infrastructure software.
  • Frisbee allows you to change the appearance of the messenger for the customer or service provider (logo, name, main colors).

Frisbee and Email
  • In Email, all e-mails fall into one box, there is no separation by projects and tasks. In Frisbee, messages are separated by channels (chats), you can disable notifications for non-priority channels and focus on the main one.
  • It is hard to perceive dialog in Email, especially when there are many replies in a chain and it is difficult to communicate in real time. Frisbee is a full-fledged messenger.
  • In Email, attachments (documents) are often lost when answering or forwarding. In Frisbee, applications are immediately visible to all members of the channel (chat).
  • An employee can "drop out" of important correspondence if he forgot to add it to the copy or clicked "Reply" instead of "Reply to all".
  • It's impossible to quickly call or organize a conference with the participants of correspondence in Email. Frisbee allows you to call all the channel members in one touch.

Frisbee and Telegram (or WhatsApp)
Data separation: There is no centralized separation of workspaces, personal and business correspondence can be mixed. Telegram has an option of grouping chat rooms, but such grouping should be done by each user himself.

Management: User accounts and chat rooms are managed by individuals. After dismissal, the employee remains in the chat rooms and maintains access to the correspondence history.

Storage and data processing: The organization does NOT own the data. The messenger operator independently manages the physical location and depth of the message archive. Data are stored and processed on the territory of other states.

Integrations: Opportunities for integration with organization' IT systems are limited. There is no centralized user management and message archive storage.
Frisbee and Skype for Business
In 2017, Microsoft has announced that it is moving all users of Skype for Business to its cloud-based corporate instant messenger Teams. Thus, Skype for Business has not developed for many years.

Frisbee allows you to organize collaborative work better than Skype through workspaces and channels, centralized data management and user management, as well as through integration with external IT systems.
Frisbee and Microsoft Teams
The main limitations of Microsoft Teams for government and other regulated organizations:
  • Microsoft Teams source code is not open. That mean that it can contain undeclared features and can create risk of security.
  • Microsoft Teams cloud servers are located in a different countries. That can lead to a direct violation of the law of personal correspondence and data security.
  • Microsoft Teams encryption algorithms are not customizable and can not fit to the national standarts of your country.
Frisbee and Mattermost
  • Both Frisbee and Mattermost can be hosted on customer servers (on-premises).
  • Mattermost uses a centralized (relational) database when placed locally. This architecture imposes restrictions on the number of users or messages per second processing. Frisbee always uses a decentralized Cassandra database, which provides horizontal scaling on all parameters.
  • Mattermost uses only American encryption algorithms. Frisbee allows the customer to select the way to protect his voice calls and messages.
  • Mattermost adds additional costs for deploying, certifying and supporting virtualization software, such as Openshift, VmWare, as well as software to protect against hacker attacks, such as F5. Frisbee provides the software infrastructure to create a secure, resilient and scalable private cloud based on open source software.

Partner Program
What does Frisbee cost depend on?
The cost of the Frisbee software part depends on the following parameters:
  • Numbers of users in the Frisbee cluster (not including external users)
  • Custom integrations that Synesis supports
  • SLA level
What are the options for selling Frisbee?
Licenses and subscriptions are sold per 1 user in the cluster (excluding external users):
  • Lifetime license (includes support and updates for the first 3 years, further paid additionally)
  • Annual license (includes support and updates for 1 year)
How does Frisbee cost compare with competitors' offers?
The average Frisbee price range is approximately equal to the price level of Mattermost Enterprise E20. Unlike Mattermost, Frisbee includes all dBrain and TheWall software infrastructure. Both these solutions meet the same transparency and security standards as the messenger itself. If you buy these components at market prices, they may cost more than the messenger. In addition, components purchased in this class are often not provided with source code.
Which organizations can become our Partners?
  • System integrators
  • Telecom and Cloud Computing Service Providers (ISPs)
  • Consulting companies
How Partner and Synesis will share their responsibilities?
  • The Partner will be responsible for marketing, promotion, design, sales, billing, first and second level technical support Frisbee to the end user.
  • Synesis will be responsible for software delivery, integrations, deployment and third level technical support. Synesis will be involved in marketing, promotion and design.
  • The software will be deployed either on the Partner's or end-user's computing infrastructure.
  • Partner concludes an agreement with an end user, and Synesis concludes an agreement with a Partner.
  • Partner shall pay to Synesis a fixed license (subscription) cost with discount or percentage of the actual income based on the license agreement.

How much and how does a Partner earn?
  • The Partner earns from 30% of the software cost (conditions can be discussed on specific projects).
  • Partner additionally earns on delivery of equipment, consulting and integration services to the end user.

Is it possible to register (protect) Partner's transactions?
Yes, transactions are registered by Synesis after the qualification of a potential Partner's client. The registration period is 1 year, it can be prolonged if there is a confirmed progress in the transaction with this client.
What is the minimum size of a Frisbee cluster?
We recommend connecting at least 1,000 users to one server application instance. Thus, the local (on-premises) deployment is suitable for large organizations. This requirement is due to the fact that Frisbee is built on "adult" cloud technologies such as Kubernetes, Ceph and Cassandra. For a smaller cluster, the cost of hardware and technical support per user will be noticeably higher. It is recommended to combine small and medium organizations (for example, a network of medical facilities) in a single cluster hosted by an integrator or service provider. The Frisbee cluster is a multi-tenant, i.e. the information spaces of each organization are completely separated by workspaces.
Is it possible to rebrand Frisbee (white label)?
Yes, it is possible to change the product name, logo and basic colors of the application under the end user or Service Provider Partner.

Rebranding is available for projects with prospects from 1,000 users.
