Gateway with no complete data control
Protection at the perimeter, but no control over the data behind it.
groupios for the critical infrastructure sector
Security begins long before the emergency.
Because resilience isn't optional -
it's a responsibility.
The groupios Mare Cloud combines secure communication, email security, archiving, and backup in a sovereign platform - developed and operated in Germany for organizations with the highest demands on availability, information security, and digital resilience.
- High availability for critical infrastructure
- NIS2- and ISO-27001-oriented security strategy
- Data sovereignty & operations in Germany
- Protection against ransomware and cyberattacks
Reality for critical infrastructure security officers
The threat landscape has changed fundamentally
Standard security is no longer enough. Targeted attacks exploit weaknesses that classic architectures systematically overlook - and hit critical infrastructure with full force.
Primary attack vectors
- Phishing with targeted identity impersonation (spear phishing)
- Business Email Compromise (BEC) - manipulation of payment processes
- Man-in-the-middle / content manipulation of unencrypted communication
- Data exfiltration via email channels with no DLP control
Systemic risks in infrastructure
- Fragmented security stacks with no integrated control layer
- Inadequate encryption - manual, incomplete, inconsistent
- Vulnerable backup systems with no isolation or resilience architecture
- Dependency on hyperscalers with no data control or auditability
Your biggest vulnerability isn't a single tool - it's the lack of integration. Classic architectures protect systems. The groupios Mare Cloud protects the data itself.
Structural problem
Why existing security stacks systematically fail
Isolated solutions with no integrated control create blind spots - exactly where attackers look.
Encryption with no central policy control
Manual processes, inconsistent application, uncontrolled exceptions.
Backups with no isolation or resilience
Centralized backups are a single point of attack.
Cloud platforms with no data sovereignty
US hyperscalers are subject to the CLOUD Act - your data too.
Security at every layer
The integrated security architecture of the groupios Mare Cloud
Five coordinated security layers - centrally controllable, fully integrated, with no compromises.
Email Security Gateway Layer
- Multi-vector threat detection across all channels
- Blocklist filtering combined with heuristic analysis
- Real-time protection from phishing, malware, and ransomware
- Automatic quarantine of suspicious content
Encryption Layer - S/MIME end-to-end
- End-to-end encryption of all communication
- Central certificate management, zero manual intervention
- Policy-based encryption - automatic
- Elimination of unencrypted communication
Data Integrity and Compliance Layer
- Audit-proof email archiving per GoBD and GDPR
- Traceability of all communication processes
- Audit-ready logging for NIS2 compliance
- Immediate availability for audits and evidence
Secure Communication Layer - Groupware
- Controlled internal and external communication
- Integration into existing system landscapes
- Central policy control across all channels
- Complete protection of all communication paths
Resilient Backup Architecture
- Cloud2Cloud Backup: isolated backup of all SaaS data
- Protection from platform outages and vendor lock-in
- Multi-Node Backup: distributed architecture with no central weak points
- Maximum ransomware resistance through isolation and automated recovery testing
Four principles that carry our architecture
Zero Trust
No implicit trust. Encryption and verification as an unchanging standard.
Defense-in-Depth
Multi-layered security architecture. Prevention, detection, and recovery in one system.
Data-Centric Security
Focus on protecting the data - not just the systems. Full control over data flows.
Resilience-by-Design
Failover-capable architecture. Backup as an active security component, not an afterthought.
Attack scenario
Phishing + ransomware + data exfiltration: the difference decides
A realistic attack scenario - and how the groupios Mare Cloud stops or neutralizes every step of the attack.
Without groupios Mare Cloud
- Phishing email reaches an unfiltered inbox
- Identity impersonation goes undetected
- Communication is compromised
- Data loss through exfiltration
- Backup encrypted by ransomware - unusable
- Critical systems down for days or weeks
With groupios Mare Cloud
- Attack is intercepted at the gateway layer
- Spoofed senders are detected via DMARC/DKIM
- Content stays fully encrypted through S/MIME
- No exfiltration thanks to controlled communication channels
- Multi-Node Backup stays intact through isolation
- Full recovery in minimal time
Relief for the IT department
What the Mare Cloud changes for security officers
Five structural benefits that fundamentally strengthen your security architecture.
Reduced attack surface
A consolidated security stack eliminates redundant interfaces and blind spots.
Increased resilience
Multi-Node Backup and failover architecture eliminate all single points of failure.
Full data control
Independence from hyperscalers. Complete transparency over all data flows.
Regulatory compliance
NIS2, GDPR, and GoBD - structurally built in, auditable, and fully demonstrable.
Operational efficiency
Central policy control reduces administrative effort and manual sources of error.
What decision-makers want to know…
How exactly does the Mare Cloud reduce our attack surface?
Through consolidation. Fragmented stacks of gateway, backup, encryption, and archiving with no shared control layer create blind spots - exactly where attackers focus. The Mare Cloud integrates all five security layers into a centrally controllable architecture. Redundant interfaces disappear, data flows are fully controlled, and policy inconsistencies are structurally ruled out.
How does the Mare Cloud's zero trust approach work in practice?
Zero trust means: no implicit assumptions of trust - neither for internal nor external communication. In the Mare Cloud, this is implemented through policy-based S/MIME encryption, applied automatically and consistently to every communication process. Certificates are managed centrally, and manual exceptions are excluded. Every communication must meet the encryption and verification standard - with no room for discretion.
How does Multi-Node Backup ensure we can recover after a ransomware attack?
Multi-Node Backup distributes backups across multiple physically and logically isolated nodes. A compromised or encrypted primary dataset can’t reach the backups - the isolation is architectural, not configurable. Automated recovery tests are also run to guarantee that recovery actually works. Single points of failure are structurally ruled out.
How does the Mare Cloud support our NIS2 requirements in a critical infrastructure context?
NIS2 requires critical infrastructure operators to demonstrate risk management measures, reporting obligations, and resilience requirements. The Mare Cloud delivers the structural foundation: audit-proof archiving of all communication, full auditability of all security processes, GDPR- and GoBD-compliant data handling, and a backup architecture explicitly designed for resilience-by-design. Compliance isn’t an add-on - it’s built into the platform.
How does a proof of concept work - and what can we validate with it?
In the proof of concept, we implement the Mare Cloud in your own environment and specifically validate the aspects critical to your security architecture: gateway integration, encryption policy, backup resilience, and auditability. Our security architecture team accompanies the entire process. At the end, you receive a complete technical assessment including an integration plan for the rollout.
Mare Cloud brings all security solutions together in a single platform.
