Teamwire: Ensuring Your Data is in Safe Hands

With Teamwire, Your Communication Is Fully GDPR-Compliant and Legally Secure.

Companies need GDPR-compliant solutions to protect data optimally and avoid costly fines. At the same time, legal certainty is essential to prevent any unwanted data misuse. With our messenger, we offer a comprehensive answer to these challenges.

Modern Encryption Technology to Protect Your Communication and Data from Cybercrime

With the ever-increasing threat of cyberattacks, companies and government agencies need to strengthen their communication security. Teamwire uses state-of-the-art encryption technology to protect your data from unauthorized access and ensure maximum security. These are the key aspects of our security measures:

• Encrypted data exchange
  

  between app and server with HTTPS (TLS 1.2 with “Perfect Forward Secrecy”). The app and server negotiate random, temporary keys that prevent a potential attacker from decrypting the network traffic afterward.

• Encrypted metadata
  

  Your metadata, including the encrypted messages, is encrypted with AES-256 before being exchanged between the client and server. Only the app and the server can decrypt these data packets. For this purpose, an individual “communication key” is exchanged with Diffie-Hellman for each device during registration to protect metadata and prevent man-in-the-middle attacks.

• Encrypted messages
  

  Messages and digital media (photos, files, etc.) are encrypted by the sender using AES-256 and only decrypted by the recipient after transmission. For this purpose, an individual key is generated for each chat and exchanged once with the chat members in encrypted form.

• Encrypted data storage on the servers
  

  All messages, digital content, and user data are stored on our servers in encrypted form using AES-256. The database key is outsourced via the so-called “Vault”.

• Encrypted storage on the end devices
  

  To protect and separate company data, user data, messages, and digital content on mobile devices are also stored encrypted with AES-256.

Privacy: Strong Protection of Privacy

Data breaches and unauthorized access to personal data are a major risk these days. Teamwire therefore relies on comprehensive measures to protect your privacy consistently. This is how we ensure that your data is always secure. Here are the key points:

Specific Functions Guarantee Absolute Data Sovereignty and Control over Your Data

Uncontrolled data flows and data loss can have serious consequences for the security and efficiency of your organization. Therefore, they need absolute sovereignty and comprehensive control over their data. This includes, among other things, where data is stored, who can access it, and how long it is stored. With its specific features, Teamwire offers you exactly this control and guarantees absolute data sovereignty.

• High service level agreements
  

  For both the cloud and on-premises versions – guarantee high system availability and reliability and fast response times to support requests.

• Continuous, redundant data backup

  All data is written synchronously to several servers, regularly backed up, and stored in encrypted form in different locations. Backups are also created continuously.

• Emergency protocols for potential emergencies
  

  Ensure rapid limitation of the source of the fault and immediate restoration of stable operation, e.g. by switching to another data center in the event of a fire or earthquake.

Company-Wide Security Through Central Administration

Companies need comprehensive and centralized management and control over all users, devices, and data to close security gaps and ensure efficiency. With Teamwire, you have exactly this centralized control over your corporate communications, thanks to an administration that makes defining and enforcing security policies simple and efficient.

Mobile Application Management to Protect Company Data on Mobile Devices

Without comprehensive mobile application management, data on employees’ mobile devices can easily be compromised. Teamwire offers a secure solution with encrypted app containers and seamless integration with leading MDM/EMM solutions. This ensures that your data remains protected at all times and your communication is secure.

Ensuring Audit Compliance and Adherence to Compliance Regulations

Without comprehensive audit compliance, companies can quickly get into legal difficulties. Therefore, Teamwire attaches great importance to audit security and compliance to make your corporate communications secure and compliant. Our solution includes features such as audit-proof archiving and professional audit logs to ensure that all legal and internal requirements are met.

Zero-Trust Security Concept to Ensure the Highest Security Standards

Teamwire consistently relies on a zero-trust security concept to ensure the highest security standards and protect your company data from unauthorized access. Here are the key aspects and benefits of our Zero Trust approach:

• Multiple authentication for users
  

  Teamwire users are authenticated via their e-mail address and telephone number to prove their identity before they can communicate with colleagues and teams.

• Two-factor authentication for administrators
  

  Teamwire administrators must first go through a multi-stage registration process. Two-factor authentication is required each time to access the administration portal. Administrators enter a password and an app-based second factor to access confidential company data.

• Permanent user and device authentication
  

  Several unique IDs and factors are checked constantly to authenticate users and end devices. This happens every time the app is accessed or opened, as well as when messages are retrieved and sent.

• Passcodes for users
  

  For added security, the IT administrator can set a PIN passcode for each employee to access the Teamwire app.

• Blocking access for users or devices
  

  The IT administrator can quickly and easily block the access of a user or end device, for example, if an employee leaves the company or their end device has been compromised.

• Minimal authorizations and rights
  

  To ensure the best possible data protection, Teamwire assigns as few authorizations and rights as necessary – at the app, server, and infrastructure levels.

• Reduced access
  

  Access via firewall, APIs, etc. is reduced to a minimum. The server only communicates with known devices. Unknown device IDs are automatically rejected.

• Strict internal security policies
  

  Teamwire treats data with absolute confidentiality and implements strict internal security policies that limit access to infrastructure, data centers, and systems as much as possible.

• Internal and external audits
  

  Regular audits, including penetration tests, vulnerability analyses, and security assessments, ensure the highest security standards. Teamwire works closely with external security companies and IT associations.
