MSPs face shrinking margins from unpredictable cloud fees and rising client risk from ransomware attacks, which surged 80% in recent years. A new approach to backup storage is needed—one that is sovereign, immutable, and predictable by design. This article explores how European object storage solves these core challenges.

The topic briefly and concisely

MSPs can secure predictable margins and eliminate vendor lock-in by using immutable backup storage with a zero-egress-fee model.

Sovereign cloud storage within the EU is essential for meeting GDPR, NIS-2, and EU Data Act requirements while avoiding CLOUD Act exposure.

S3 Object Lock provides an unbreakable defense against ransomware by making backup data immutable, ensuring it cannot be encrypted or deleted by attackers.

For Managed Service Providers, the pressure is constant: deliver flawless data protection while navigating razor-thin margins. Traditional cloud storage models often introduce unpredictable costs like egress fees, directly impacting profitability by up to 15%. Simultaneously, with ransomware attacks in Europe set to hit a record high in 2025, client data has never been more at risk. This landscape demands a shift towards immutable backup storage for MSPs that guarantees cost control, compliance, and resilience. European-based, S3-compatible object storage with Object Lock offers a clear path forward, ensuring data sovereignty and creating a foundation for secure, profitable growth.

Meet Rising Demands for Data Sovereignty and Compliance

A majority of EU decision-makers now demand European solutions for critical data, making EU data residency a primary selection criterion. For MSPs, offering GDPR-compliant solutions is no longer optional; it's a competitive necessity. Storing backup data exclusively in certified European data centers ensures it remains under EU law, avoiding CLOUD Act exposure completely. This approach simplifies compliance for clients in regulated industries like finance, where data residency is crucial. Impossible Cloud’s country-level geofencing provides verifiable proof of data location, a key requirement for over 60% of enterprise buyers. This focus on digital sovereignty builds client trust and unlocks new opportunities. Transitioning to a sovereign cloud platform prepares your service offerings for upcoming regulations.

Build Unbreakable Ransomware Defenses with Immutable Storage

Ransomware remains a top threat, with global attacks increasing 21% in the second quarter of 2025 alone. Immutable storage, enabled by S3 Object Lock, creates a Write-Once-Read-Many (WORM) copy of backup data that cannot be altered or deleted by anyone—not even administrators—for a defined period. This renders ransomware encryption attempts useless. Even if a threat actor breaches a network, the backup data remains secure and recoverable. Immutable backups are a core component of a modern 3-2-1 or 4-2-2 data protection strategy. Implementing immutability offers a powerful defense that over 70% of clients now expect. Key benefits of using S3 Object Lock for ransomware protection include: verifiable integrity, guaranteeing that backup files are exact, unaltered copies of the original data; a WORM model, preventing encryption, modification, or deletion of backup objects during the retention period; compliance readiness, helping meet strict data retention rules for regulations like GDPR and for financial audits; and rapid recovery, ensuring a clean, reliable data copy is always available for fast restoration after an attack. This technology transforms backup storage from a passive safeguard into an active defense mechanism.

Achieve Predictable Margins with a Transparent Cost Model

For MSPs, profitability hinges on predictable costs, yet hyperscale providers often erode margins with hidden fees. A 2022 market study revealed that excessive egress fees are a primary cause of vendor lock-in and unpredictable billing. These fees can inflate a monthly bill by 20% or more during a large client restore. Impossible Cloud eliminates this uncertainty entirely. Our model features zero egress fees, no API call charges, and no minimum storage durations. This transparent approach allows MSPs to build BaaS and DRaaS offerings with stable, defensible margins of at least 30%. With the EU Data Act set to ban egress fees by 2027, our model positions partners ahead of the curve. You can provide clients with clear, predictable pricing while protecting your own bottom line.

Simplify Operations with an 'Always-Hot' Architecture

Complex storage tiering introduces operational risk, with restore delays and API timeouts causing failures in up to 15% of urgent recovery scenarios. An “Always-Hot” storage model eliminates these challenges by ensuring all data is immediately accessible without any restore delays or retrieval fees. This simplifies backup and recovery workflows for tools like Veeam and NovaBackup, which expect consistent, low-latency access. This architectural choice reduces operational complexity by an estimated 25% compared to tiered systems. It ensures that every restore operation, whether for a single file or a full system, performs predictably every time. This reliability is critical for meeting stringent client Service Level Agreements (SLAs).

Leverage a Partner-Ready Platform Built for Growth

A successful partnership requires more than just great technology; it demands a platform built for the channel. Our partner console is designed specifically for MSPs to manage multiple clients efficiently and securely, providing the essential tools needed to scale your backup services. We are also expanding our reach with new distribution agreements through partners like api in Germany and Northamber plc in the UK, making it easier for local resellers to get started. This growing ecosystem provides the support MSPs need to thrive. Our partner-ready platform includes: multi-tenant management for securely managing multiple client accounts from a single, intuitive interface with robust role-based access control (RBAC); full automation, utilizing a fully S3-compatible API and CLI to automate workflows from bucket creation to user provisioning; integrated security, enforcing strong security with multi-factor authentication (MFA) and granular IAM policies for every client; and simplified onboarding, getting new clients set up in minutes, not days, with out-of-the-box integrations for leading backup tools. This focus on partner enablement ensures you can deliver high-value MSP backup solutions without operational friction.

Future-Proof Your Services for Emerging EU Regulations

The European regulatory landscape is continuously evolving, with two key directives set to impact MSPs directly. The NIS-2 Directive, which EU member states must adopt by October 2024, mandates stricter cybersecurity measures, including supply-chain assurance and incident reporting. It requires a continuous security process that our platform supports by design. Furthermore, the EU Data Act, applicable from September 2025, champions data portability and interoperability, giving customers the right to easily move their data. Our commitment to open standards and S3 API compatibility ensures you can offer clients a true exit path, preventing vendor lock-in. By building your services on a platform already aligned with these future requirements, you gain a competitive advantage and demonstrate long-term value to your clients.
