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 afterwards.

  • 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-Hellmann 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:

  1. Anonymized user data

    Teamwire largely anonymizes personal data and treats all data with absolute confidentiality.

  2. One-way encrypted passwords

    All IDs, phone numbers, e-mail addresses, and passwords are converted before storage using one-way encryption functions such as SHA-256 and other secure algorithms.

  3. The address book is not saved

    To protect your contacts, all contact data is anonymized using hash functions (SHA-256) and deleted from our servers immediately after connecting with colleagues. The user’s address book is not saved.

  4. No metadata analysis

    No analyses of metadata, users or their communication take place.

  5. Simple user settings

    Thanks to our easy-to-use app, you don’t have to make any complicated settings to protect your privacy. You select a chat for communication simply and the messages are only sent to the recipients of this chat.

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.

Configurable retention periods for servers
and automatic deletion of data from the server after the deadlines have expired.
Configurable retention periods for apps
and automatic deletion of data in the app after the deadlines have expired.
Remote data erasure
In the case of “data loss prevention”, for example, if an end device is lost or stolen, the IT administrator can remotely delete all data and content of the app on the affected device.
Granular policies for data access
to define company-wide rules for data access. These policies prevent the distribution of data (e.g. via “copy & paste”) or the sending of digital content (e.g. photos). Your IT administrator has around 40 granular policies at their disposal, which can be configured differently for access via mobile app, desktop PC, browser client, and bot, depending on the security requirements.
Secure integrations and connections
Teamwire has developed all integrations, interfaces, and APIs for third-party providers. This means we have complete control over the data exchanged with these solutions and prevent uncontrolled data leakage.
Deactivating the message preview
If your organization wants to prevent messages from appearing or being delivered in push notifications from Apple, Google, or Microsoft, message previews can be disabled for all users company-wide.

Professional audit log
These record a chronological log of all safety-relevant activities and enable comprehensive traceability.

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.
