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.

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).
  

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.

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.

We are working on Frisbee functionality that will allow organizations to securely connect external collaborators to individual chats and group calls.

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.

Yes, a user can work in Frisbee from multiple devices simultaneously. The number of user devices is unlimited.

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.

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.

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.

Yes. Frisbee cluster is multi-tenant.

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. KLAUD ATLAS is experienced in supporting large Ceph clusters of dozens of petabytes.

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.

• 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.

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).

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).

Yes, Frisbee has an open REST API for embedding chat into customer applications and creating chat bots.

Yes, Frisbee can synchronize with Active Directory and update the user card, including name, phone number, email, position.

Routing voice calls (including group calls) from Frisbee to conventional phones can be implemented on demand through the corporate VoIP/SIP gateway.

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.
  
  

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.

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.

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).
  
  

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.

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.

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.
  

Express:
Data separation: One corporate space and one personal
Architecture: Multiple Server Federation
Infrastructure software: Not included (brings additional costs)

Frisbee:
Data separation: Unlimited number of workspaces
Architecture: A complete private cloud with centralized management of all servers (carrier-class solution)
Infrastructure software: Includes:
Kubernetes orchestration
Distributed Ceph Storage
Distributed Cassandra database
Other services

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 KLAUD ATLAS supports
• SLA level

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)
  

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.

Yes, transactions are registered by KLAUD ATLAS 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.

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.

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.
