Why Traditional MSP Security Models Are Falling Short for Today’s Businesses
In the rapidly evolving world of cybersecurity, many organizations are still holding onto outdated ideas. While it might seem simple to divide responsibilities between your company and your managed service provider (MSP), the reality is far more complex. As environments become increasingly hybrid, cloud-based, and interconnected, the lines of responsibility blur, creating risky areas of uncertainty.
The Blurring Lines of MSP Security
The days of clearly defined IT environments are long gone. Today’s environments span cloud platforms, containers, APIs, and remote teams, leading to overlapping responsibilities. For instance, while your MSP might manage hardware and physical security, virtual network segments and access policies often fall under your responsibility. Similarly, while your MSP may handle patching for platforms or middleware, user access, integrations, and app configurations are typically your concern.
The Risks in the Uncertain Zones
The most significant risks lurk in the areas where roles are not clearly defined. Consider these scenarios:
- Configuration Drift: Your MSP sets a secure default, but your team tweaks it for performance or user satisfaction, introducing unmonitored vulnerabilities.
- Incident Response Chaos: You detect an anomaly in your app, but lack visibility into the underlying infrastructure. Meanwhile, your MSP notices unusual network traffic but lacks context about your app, leaving both sides without a complete picture.
- Compliance Assumptions: Just because your MSP has certain certifications doesn’t mean your specific use case is covered. You might assume compliance until an audit reveals otherwise.
Building a Framework for Clarity
While you can’t eliminate complexity, you can manage it effectively. Start by establishing a dynamic framework that clearly defines responsibilities and adapts to your evolving environment. Key components include:
- Security Control Mapping: Assign each control to a specific owner and define the coordination process for shared controls.
- Ongoing Matrix Maintenance: Regularly revisit your control matrix to keep it up-to-date.
- Risk-Based Ownership: Align responsibility with actual risk levels. A development sandbox shouldn’t be treated the same as your payment systems.
- Clear Communication Channels: Ensure both sides understand who to contact, when to escalate, and how to collaborate during changes or crises.
Leveraging Technology for Better Boundaries
Once your framework is in place, technology can help enforce it and maintain visibility. Consider these solutions:
- Security Orchestration Integration: Achieve real-time visibility through connected monitoring and policy enforcement across both your and your MSP’s systems.
- Zero-Trust Principles: Implement identity-first security, micro-segmentation, and continuous verification that work regardless of resource ownership.
- DevSecOps Handoff Clarity: Seamlessly integrate security testing and vulnerability management into shared deployment pipelines to avoid finger-pointing.
Contracts and Legal Considerations
If your contracts focus solely on uptime and ticket resolution, they’re missing critical elements. Modern environments demand sophisticated language that defines what happens when things go wrong, not just when they go right. Ensure your contracts cover:
- Who is responsible for preserving logs?
- How will you coordinate with regulators or legal teams after a breach?
- What are your shared obligations under laws like GDPR or CCPA?
Implementation and Continuous Improvement
Treat your shared responsibility framework as a product that requires maintenance, iteration, and feedback. Regularly review it against new threats and business shifts, use shared dashboards for visibility and alignment, run joint tabletop exercises to pressure-test assumptions, and track metrics like response time, detection success, and ownership clarity to refine the model.
Emerging technologies, from AI to edge computing, will only increase complexity. The organizations that succeed will be those that build real partnerships with their MSPs, backed by clear, adaptable frameworks and mutual accountability. You don’t need to simplify the environment; you need to be more strategic in managing complexity. That starts by bringing clarity to the uncertain zones before they become a liability.
