“I’ll send a quick message via WhatsApp.” Why this is precisely the problem.<\/span><\/h2>\n

An IT manager in city administration, a doctor on emergency duty, an operations manager at the fire department, or the closest government circle \u2013 they all face the daily challenge of passing on information quickly and securely<\/strong>.<\/span><\/p>\n

Reaching for a private smartphone and the familiar messenger is often an obvious choice. A quick update via WhatsApp, an assessment of the situation via Telegram, and feedback via Signal are fast, practical, and insecure<\/strong>.<\/span><\/p>\n

What may be considered harmless in the private sphere is a risk<\/strong> at the level of authorities, critical infrastructure, public safety, and health \u2013 legally, technically, and politically. The requirements for secure communication between authorities are higher today than ever before, and they cannot be met with standard messenger apps.<\/span><\/p>\n

In this article, you will learn why this is the case, which criteria count<\/strong>, and why Teamwire was built precisely for this purpose.<\/span><\/p>\n

Standard messenger: fast, practical – but not suitable for the authorities<\/span><\/h2>\n

Signal, WhatsApp, and Telegram are familiar to millions of users. They are intuitive, work across all devices, and offer security functions such as end-to-end encryption. But appearances are deceptive and caution is advised<\/strong>, especially for authorities.<\/span><\/p>\n

These apps were developed for the mass market. They are subject to commercial interests and often regulatory requirements outside the EU<\/strong>.<\/span><\/p>\n

They cannot be managed centrally, offer no granular assignment of rights, do not offer audit-proof archiving, or provide control over storage locations and data flows<\/strong>.<\/span><\/p>\n

Telegram even completely dispenses with transparent encryption, and WhatsApp, as part of the Meta Group, has been under close scrutiny for years regarding data protection<\/strong>.<\/span><\/p>\n

Recent incidents such as the so-called\u00a0<\/span>“SignalGate” scandal<\/span><\/a> in the USA show that caution is required.<\/span><\/p>\n

US ministers and other high-ranking government officials exchanged secret military plans<\/strong> for attacks in Yemen via the messenger Signal \u2013 in a group chat that inadvertently included a journalist from <\/span>The Atlantic<\/span><\/i>.<\/span><\/p>\n

This incident shows how quickly minor carelessness can cause significant security gaps<\/strong> in government communications, especially with solutions not designed for this purpose<\/strong>.<\/span><\/p>\n

In government communication, such errors are not only embarrassing but potentially dangerous<\/strong>.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Secure communication between <\/span>authorities must meet these 7 requirements<\/span><\/h2>\n

So what does it take to make communication at the authority level truly secure, GDPR-compliant, and efficient<\/strong>?<\/span><\/p>\n

The following seven points<\/strong> provide clear guidance:<\/span><\/p>\n

1. State-of-the-art encryption \u2013 without backdoors<\/span><\/h3>\n

Confidentiality is non-negotiable. Sensitive communication can only be protected if all messages, files, and calls are consistently encrypted<\/strong> and there are no provider backdoors.<\/span><\/p>\n

2. Metadata economy<\/span><\/h3>\n

Not only is content critical. Metadata such as “Who communicates with whom and when?” also says a lot. A solution for secure communication between authorities must also be limited to the bare essentials<\/strong> when collecting and analyzing metadata.<\/span><\/p>\n

3. Reliable authentication<\/span><\/h3>\n

Security-relevant communication requires clear identities<\/strong>. Only with verified users \u2013 for example, via single sign-on or connection to central directory services \u2013 can it be ensured that no one gains access unnoticed.<\/span><\/p>\n

4. Mobile device management (MDM) and central administration<\/span><\/h3>\n

Devices in public authorities and organizations must be able to be centrally configured, locked, deleted<\/strong>, or assigned usage guidelines.\u00a0<\/span>This is only possible with a centralized administration and ideally the support of an MDM platform.<\/p>\n

5. Archiving and documentation<\/span><\/h3>\n

Audit-proof communication<\/strong> is mandatory for audits, proof, or public transparency. Messengers without export or archiving functions fail here.<\/span><\/p>\n

6. Storage periods and retention policies<\/span><\/h3>\n

Data must not be stored indefinitely or deleted unregulated. Legally compliant communication means defined retention periods, automatic deletion concepts, and documented data storage<\/strong>.<\/span><\/p>\n

7. Hosting in the EU for genuine data sovereignty<\/span><\/h3>\n

A key requirement for trustworthy communication is that all data remains in Europe<\/strong>. This is the only way to guarantee GDPR compliance. Even better: hosting in an ISO-certified, BSI-C5-compliant data center.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Data sovereignty is no longer a nice-to-have but a strategic necessity<\/span><\/h2>\n

The discussion about Europe’s independence from US cloud services<\/strong> has taken on a new urgency due to laws such as the CLOUD Act, the<\/span> restriction of the PCLO<\/span><\/a>, and the consequences of the Schrems II decision.<\/span><\/p>\n

Any public authority or critical institution that relies on messaging services not subject to European regulation exposes itself to compliance risks<\/strong> and risks of losing control<\/strong> over sensitive information.<\/span><\/p>\n

So, it’s not just about data protection. It’s about\u00a0state sovereignty<\/strong>,\u00a0digital resilience<\/strong>, and the\u00a0credibility<\/strong> of public communication, which<\/span>\u00a0is particularly crucial in security-relevant areas.<\/span><\/p>\n
