EVAC by mailbox: Business continuity and business continuation

mailbox presents EVAC: Business continuity at the touch of a button

Berlin, 21 January 2026 - mailbox launches EVAC, a ready-to-use secondary IT communication structure for companies and the public sector. With the new solution, organisations can ensure the continuity of their communications in the event of a failure of their primary structure due to cyber attacks, server outages or natural disasters and thus remain capable of acting. EVAC by mailbox enables the fulfilment of central NIS-2 requirements and the BSI 200-4 standard for business continuity management.

Business continuity: Growing threat situation and regulatory requirements

According to the World Economic Forum, 72 % of all organisations worldwide reported an increasing cyber risk in 2025. The consequences are serious: according to IBM, the average downtime after cyber attacks in 2024 was 185 days. Survey results from Bitkom put the damage caused by cybercrime in Germany alone at 178.6 billion euros in the same year. Organisations need a reliable emergency solution in order to be well prepared to deal with this growing threat situation and a failure of their communication and collaboration infrastructure.

In accordance with the NIS-2 Directive and the German law implementing NIS-2, companies and authorities must prove that they have functioning business continuity measures in place. EVAC supports organisations in fulfilling specific NIS-2 requirements, e.g. in risk management, incident response and reporting obligations. In addition, EVAC helps to fulfil the requirements of BSI Standard 200-4 on business continuity management: As part of the business continuity plan (CFP), EVAC enables the continuation of time-critical business processes.

EVAC: Complete communication capability in three steps

The mailbox solution comprises a complete communication and collaboration infrastructure in the web interface: Email communication, video conferencing, cloud storage, online office, calendar, address book and task management. For maximum availability, mailbox hosts all data 100 % GDPR-compliant in secure, redundant data centres in Germany.

EVAC was specially developed to minimise the recovery time objective (RTO) in the event of a crisis and thus reduce downtime. The business continuity solution works in three simple steps:

1. Selection and preparation: Select the desired mailboxes and data – additions and removals are possible at any time. EVAC infrastructure is ready in standby mode.

2. Activation in the event of a crisis: Emergency mailboxes are activated and employees automatically receive instructions on password assignment and access.

3. Communication continues: Employees access their mailboxes and collaboration tools via webmailer – business communication continues without interruption.
