Why cyber resilience is more than just IT security

Cybersecurity protects. Cyber resilience keeps you operational.

When protection fails

Firewall, backup, virus scanner — all in place. But when systems are hit, emails fail, the control center is offline, or no one knows who’s in charge, operations quickly grind to a halt.

Beyond cybersecurity

Cybersecurity alone is no longer enough. Organizations must be resilient – able to act during IT outages, ransomware attacks, or technical failures.

Business continuity

To ensure true business continuity, you need a reliable fallback tool. With Teamwire, you meet NIS-2, DORA and CER requirements and stay connected – even in an emergency.

Teamwire: Your reliable communication solution

Fail-safe communication even during IT disruptions

If mail, VPN, or Microsoft Teams fail, Teamwire can still be reached. As an independent back-up channel, it ensures that teams stay connected. Even in the worst-case scenario, there is no operational paralysis – everyone is reachable and able to make decisions.

Separate infrastructure and cluster server: Communication remains functional, even if mail servers, VPN, and Microsoft Teams fail

Emergency communication: Alert in seconds, coordinate live, and reach entire teams with one click – regardless of compromised IT

Secure communication during cyberattacks

Ransomware or DDoS attacks can paralyze entire organizations. A common scenario: company address books become inaccessible, cutting off critical contacts. Teamwire keeps information flowing, enables rapid response, minimizes damage, and keeps leaders in control.

Frequently asked questions (FAQs)

What is cyber resilience and why does it affect more than just the IT department

Cyber resilience means that an organization remains capable of working and making decisions despite cyber attacks, disruptions, or IT failures. It is not just about protection (firewalls, virus scanners), but about the ability to act when these protective mechanisms fail. Communication is key here—without communication, no crisis team can function. Teamwire ensures precisely this ability to act.

How does Teamwire help when systems such as email, VPN, or Teams fail?

Teamwire runs completely independently of your main IT system and remains available even if mail servers fail, the VPN is unavailable, collaboration tools such as Microsoft Teams are offline, or control center systems have been attacked. This gives you a reliable secondary channel that works in any situation.

Is Teamwire GDPR-compliant and legally secure in the event of cyberattacks?

Yes. Teamwire offers:

Hosting in Germany
ISO 27001 / BSI-C5
Zero-Trust
Complete, modern encryption of all data and metadata
full auditability

Furthermore, Teamwire is not subject to US jurisdiction, as it does not involve US clouds, the CLOUD Act, or data transfers to third countries.

How is crisis communication documented—including for NIS-2 or DORA?

Teamwire offers audit-proof archiving, audit logs, verifiable administrator actions, and exportable chat histories. This means that every action is traceable—a crucial criterion for audits and mandatory documentation.
